Current Status and Future Trends in Psychedelic (LSD) Research

       Since the discovery of d-lysergic acid diethylamide (LSD-25) 
in 1943, a voluminous literature has accumulated concerning its 
effects on a variety of animals, including man. Despite the mass 
of published reports, definitive evidence is generally lacking, 
particularly with regard to the subjective and behavioral effects 
both during and subsequent to the LSD induced state. It is well 
established that this powerful agent produces major alterations 
in cerebral processes and central autonomic functions. There is 
also ample evidence indicating a markedly lowered threshold for 
arousal (Key & Bradley, 1960) and an increased sensitivity to 
stimuli in all modalities (Klee, 1963). These 
psychopharmacological effects parallel the findings of clinical 
and behavioral studies at least on the molar descriptive level. 
Pronounced perceptual changes have been almost invariably 
demonstrated with concomitant alterations in affect, ideation, 
and the relationship between subject and environment (Hoffer, 
1965). Beyond these rather global findings, results have been 
inconsistent and often contradictory, even within species far 
less complex than man (Cohen, 1964).   
 
       The well-known methodological problems encountered in 
research with centrally acting drugs are at least partly 
responsible for the slow progress thus far (Zubin & Katz, 
1964). This has been especially true with human subjects. 
Systematic study of human reactions to LSD poses unique problems 
associated with greater organic complexity, shortcomings of 
currently available measuring devices, the ubiquity of individual 
differences, lack of an adequate theoretical model, and the 
influence of non-drug variables such as set and setting. In 
addition to these experimental obstacles, LSD has until recently 
been the center of a complicated medico-legal-social controversy 
(Harman, 1964). This has tended to obscure the relevant empirical 
questions and inhibit investigations which are both imaginative 
and reasonably objective.   
 
   
AMBIVALENCE IN A PERIOD OF TRANSITION
 
 
       The short but illustrative history of LSD-25 (a) as a subject 
of research, (b) as a psycho-social phenomenon, and (c) as a 
theoretical or philosophical enigma may be viewed as a case study 
of significant trends in contemporary psychology and psychiatry. 
It is equally instructive to reverse the process by viewing the 
growing interest and fascination with altered states of 
consciousness from the perspective of recent shifts in 
psychological theory and research. As young disciplines lacking 
stable direction, self-scrutiny and constant revision 
characterize the social sciences. And in the light of their 
subject-matter, these fields are particularly attuned to the 
wider culture. In this connexion, recent developments in the 
philosophy and sociology of science emphasize the transactional 
interplay between theory, observer, and actuality. Rather than 
laws of nature, theory and evidence are more accurately viewed as 
working fictions or convenient myths and reflect the belief 
system of a given time and place (Holten, et al., 1965). A rather 
extreme version of this "Indeterminacy Model" of 
science has been described by Alfred de Grazia (1963, p. 56):   
 
 
    
      The model suggests that the spirit of the times and 
    customs dictate what will and will not be science.... 
    Scientists operate under the indeterminacy system by various 
    mythsprimarily of rationality, of causation, and of 
    power of choicebut in fact do not know what they are 
    seeking, what is available, or what are solutions. That their 
    compensation, whether in esteem, position, or money, is 
    related to performance is only an illusion. What is accepted 
    and what is rejected are therefore only a product of chance 
    encounters of purpose and provision.   
 
 
       A growing body of empirical evidence supports the view that 
science as a branch of human endeavor is socially and 
psychologically conditioned just as any other human activity 
(Rosenthal, 1963). From this perspective, contemporary 
theoretical issues and recent shifts in psychological research 
become a sensitive barometer of the present social climate and 
also a timetable of significant cultural trends. A case in point 
is the recent emergence of a "third force" in American 
psychology with its emphasis on personal growth and greater 
realization of human potentialities. The third force in 
psychology has counterparts in each of the arts and science. (1) Collectively, they 
represent a concerted effort to counteract the progressive 
subordination of personal identity to what Erik Erikson calls the 
"technological superidentity" (1962). Interestingly, 
they also share a highly positive vision of modern man's 
foreseeable possibilities. This ambivalent, somewhat paradoxical 
position suggests that contemporary humanistic thinking has been 
inspired not only by the dehumanizing effects of the 
scientific-industrial complex, but also by its capacity for 
making the lives of men healthy, safe, and reasonably secure for 
the first time in history.   
 
       Traditionally, the motive power of western cultures has 
necessarily focused on survival and environmental 
masteryhuman strivings which are highly congenial to a 
behavioristic or psychoanalytic frame of reference. In contrast 
to these orientations, Maslow views the organismic equilibrium 
made possible by satiated bodily needs, physical safety, and some 
measure of psychological security as merely prerequisite to more 
uniquely human pursuits. This hierarchical conception of man's 
strivings depicts him as a self-directed creature with impulses 
toward creative expression and self-enhancement as well as 
homeostatic maintenance (Maslow, 1962).   
 
       It is too early to gauge the extent to which Maslow's 
humanistic image of man meshes with the modern temper. On the 
other hand, considerable evidence has already accumulated 
indicating that behaviorism and psychoanalysis, in their orthodox 
forms, no longer have what Bruner describes as "an immediate 
resonance with the dialectic of experience" (1962). Yet 
their continuing impact on our self-and world-view is clearly 
substantial. Thus, three divergent orientations occupy the same 
stage concurrentlyreflecting and in turn effecting social 
values and individual conduct. Viewed comparatively, these 
equipotent theories of man and the research they generate give 
testimony to the preoccupations and uncertainties of our time.   
 
       Placed within this broader context, the diverse descriptions 
and interpretations of the LSD experience become more 
understandable. And since psychedelic, 
"mind-manifesting," substances have been known and 
ingested throughout man's history (Barnard, 1963), the current 
fascination with this class of experiences seems particularly 
significant. Although presently unclear, one general reason for 
the increasing interest in psychedelic phenomena can be 
identified: either as a means of investigating higher thought 
processes or as a potentially valuable personal experience, the 
LSD-induced state is intriguing because it meshes with the 
zeitgeist in the social sciences and with major trends in the 
larger culture. There is convincing evidence from a variety of 
quarters which supports this contention.   
 
   
EXPERIMENTAL PSYCHOLOGY: THE RETURN OF THE OSTRACIZED
 
 
       In a recent issue of the American Psychologist, an 
incisive paper by a well-known research psychologist is entitled, 
"Imagery: The Return of the Ostracized" (Holt, 1964). 
After examining the traditional scientific and cultural 
resistances to such phenomena as pseudohallucinations, hypnogogic 
and dream images, extrasensory perception, and hypnosis, the 
author goes on to describe the current status in these fields. 
Echoing Hebb's manifesto as president of the American 
Psychological Association (1960), he points to a number of recent 
breakthroughs in a variety of research areas which signal the 
second phase of a psychological revolution. The first phase, 
covering the first half of the century, was characterized by the 
scientific extremism of psychoanalysis and behaviorism; movements 
which purged psychology of the unique and the private. While both 
psychoanalysis and behaviorism in their orthodox forms have made 
valuable contributions to our understanding of man, it seems 
evident now that these orientations can no longer exclude altered 
states of consciousness and novel perceptual experiences from the 
primary subject-matter of a normal psychology.   
 
       Significantly, some of the leading exponents of both theories 
such as B. F. Skinner (1963) and H. Hartmann (1958) have 
recognized these omissions and indicated a need for revision. 
Consistent with theoretical developments, behavioristic research 
shows an increasing concern with internal processes including 
sensations, images, and cognitions (London & Rosenhan, 1964). 
Similarly, psychoanalytic studies focus more on normal or 
superior functioning and less on pathology (Frosch & Ross, 
1960). These trends are not surprising since some of the most 
exciting developments during the past decade have occurred in 
experimental work with dream activity, sensory deprivation, 
creativity, hypnosis, and the psychedelic drugs. Viewing this 
rich array of research activity as occurring within a broader 
cultural context, one convergent finding seems of major 
significance; namely, that richness of imagination and so-called 
regressive experiences are not the exclusive privilege of madmen 
and artists. Instead, this work indicates quite conclusively that 
under favorable circumstances, most people can greatly expand 
their experiential horizons without sacrificing effectiveness in 
dealing with conventional reality.   
 
       The significant parallels among relatively independent lines 
of investigation are most striking. First it should be noted that 
each of these phenomenon (psychedelic, dreams, creativity, 
sensory isolation, and hypnosis) have traditionally been 
associated with the negative, bizarre, and abnormal. Until 
recently dreams and hypnosis have generally been linked with 
magic and the occult. Similarly, "hallucinogenic" drug 
states, sensory confinement, and inordinate creativeness have 
strong historical associations with defective character and 
insanity. As a result, these classes of experience have typically 
been treated as isolated phenomena, discontinuous with other 
psychological processes and inexplicable in terms of known 
principles.   
 
       Although presently accepted as legitimate areas of study, the 
tainted heritage of novel experiences has continued to exert 
strong influence. For example, recent findings indicate that the 
main features of creativity and the necessary conditions for its 
development run counter to prevailing ideologies (Getzels & 
Jackson, 1962; Gruen, 1964). Similar cultural and professional 
resistances have been documented regarding the psychedelic drugs 
with particular reference to their presumed 
"psychotomimetic" properties (Savage & Stolaroff, 
1965). The same biases have been noted in perceptual isolation 
research. In their recent critique, Arnhoff and Leon (1964) 
conclude that most studies of sensory deprivation effects have 
grossly misapplied the concepts and terms of pathology. In much 
the same vein, Shor's (1960, p. 162) work on 
"hypnotic-like" experiences in normal subjects 
indicates that:   
 
 
    
      In our culture naturally-occurring hypnotic-like 
    experiences tend to be regarded with some misgivings if not 
    as outright pathology. Consequently they are little talked 
    about, but this does not mean that they occur with less 
    frequency or profundity than in cultures where they are 
    encouraged or institutionalized. In many cultures such 
    experiences are seen as a vital source of creative 
    inspiration and gratification.   
 
 
       A second significant parallel concerns the remarkable 
subjective and behavioral similarities of these experiences. 
Consistent findings in research on hypnotic, psychedelic, and 
dream states, certain phases of the creative process, as well as 
sensory and dream deprivation indicate an almost complete overlap 
of major effects. Reported communalities include significant 
alterations in perception, dominance of sensation and imagery 
over verbal-associative thinking, relaxed ego boundaries, changes 
in bodily feelings, and the suspension of conventional 
realityorientation to space, time, and self.   
 
       Theoretical accounts of these psychological changes have also 
run parallel. Whether self-induced or situationally induced by 
means of fatigue, drugs, or some form of stress, such states have 
typically been viewed as regressive, infantile, or primitive, 
indicating sudden loss of ego control and the eruption of 
unconscious forces. Until very recently, the effects have been 
interpreted as disturbing, incapacitating, quasipsychotic, 
dissociative, or depersonalizing. Consistent with these 
interpretations, persons prone to altered states of awareness 
have generally been described as poorly adjusted, suggestible, 
irrational, passive, and low in ego strength. (2)   
 
       Perhaps the most important parallel concerns the current 
status and direction of research in these areas. At the present 
time, work in each area reveals a discernible shift away from 
investigating the condition or phenomenon per se, focusing 
instead on the situation-and subject-determined variables. This 
significant turning point calls attention to the key importance 
of the psycho-social context in which these experiences are 
inextricably embedded. Related to this new research strategy, 
recent findings and shifts in theorizing about altered states of 
consciousness have taken a more positive turn.   
 
       As a case in point, the aftereffects of dream deprivation, 
both positive and negative, vary widely across subjects. Dement 
(1960) found that "the kinds of alterations represent 
extensions or revelations of tendencies native to the individual 
personality" and that their form, degree, and dynamic 
meaning were influenced by the setting and by interpersonal 
transactions. With regard to hypnotic susceptibility, Barber 
(1964) has established the central importance of attitudinal and 
motivational variables. Similarly, recent findings indicate that 
the nature and intensity of hypnotic experiences are strongly 
influenced by the sociopsychological milieu, particularly the 
mutual expectancies of subject and experimenter (Sarbin & 
Lim, 1963).   
 
       The same trends are found in sensory deprivation research. 
Considerable evidence has accumulated indicating that greatly 
reduced sensory input can impair or facilitate mental functioning 
depending on the particular interaction of set, setting, and 
personality (Brownfield, 1964). For example, Leiderman (1964) 
found that "with the element of fear removed, the imagery of 
sensory deprivation becomes like the imagery of daydreams, quite 
familiar and usually not anxiety-producing." Interestingly, 
sensory deprivation is reportedly therapeutic for some patients 
(Zuckerman, 1964). The direction of thinking in this area is 
perhaps best summed up by Suedfeld (1964). Noting that some 
experimentally isolated subjects reveal striking creativity in 
solving problems, he poses the question, "What would happen 
if creative behavior were externally reinforced by the 
experimenter?"   
 
       Turning to the psychedelics, it has become apparent that 
adverse psychological or behavioral effects are not 
drug-specific. More generally, the nature, intensity, and content 
of the experience are the result of complex transactions between 
the subject's past history and personality, the set and 
expectancies of both subject and administrator, and the physical 
and psychological setting in which the experience takes place 
(see e.g., Unger, 1964a). As in the case of related phenomena, 
most of these determinants of response to LSD can be 
intentionally arranged and manipulated so as to foster either a 
propitious or a stressful experience. In the search for 
relatively invariant or "drug-specific" reactions much 
of the research until recently has failed to assess, control, or 
systematically vary relevant non-drug variables.   
 
       Laboratory studies of behavioral effects during the 
LSD-induced state have been particularly insensitive to 
situation-and subject-determined variables. Changes in 
performance levels on a wide variety of tasks have been 
extensively investigated with inconclusive results. Instrumental 
learning has been found to be impaired (Krus et al., 1963), 
enhanced (Rosenbaum et al., 1959), and unchanged (Kornetsky, 
1957). Both impairment and enhancement of color perception have 
been reported (Wapner & Krus, 1960; Hartman & Hollister, 
1963). Similarly, studies of the effects of LSD on recall and 
recognition, discrimination learning, concentration, symbolic 
thinking, and perceptual accuracy have yielded contradictory 
results (see e.g., Trouton & Eyesenck, 1961). It is perhaps 
significant that most of the laboratory research has used the 
drug as a stressor with the intention of simulating 
psychotic-like performance-impairment (psychotomimetic 
orientation). In contrast, well over three hundred clinical 
studies on the therapeutic effectiveness of LSD have reported 
almost uniformly positive results (Hoffer, 1965; Mogar, 1965a). 
This more recent line of investigation views the drug as a 
liberator which facilitates accurate perception, self-insight, 
and performance-enhancement (psychedelic orientation). Consistent 
with their objectives and positive findings, clinical studies 
have generally (a) optimized the context of the drug experience 
and (b) been particularly attentive to individual differences in 
personality and set.   
 
       A number of studies have demonstrated that personality 
differences are as important as preparation and setting in 
determining response to LSD. In a study of immediate and 
long-term effects of the psychedelic experience, Mogar and Savage 
(1964) found that post-LSD changes were related to personality 
styles and modal defense patterns. The results indicated that 
subjects with a well-defined but flexible self structure 
responded most favorably to the drug, while those with either 
under-developed or overly-rigid ego defenses responded less 
favorably. Similar differential findings have been obtained 
recently in work with sensory deprivation and hypnosis. For 
example, both neuroticism and "field-dependence" 
correlate significantly with disturbing, stressful reactions to 
sensory deprivation (Zuckerman & Cohen, 1964). Other 
isolation studies have found positive relationships between 
"field-independence" and performance-enhancement 
(Brownfield, 1964), and between "self-actualizing 
maturity" and enjoyment of sensory deprivation (Blazer, 
1963). Particularly relevant to the psychedelics is the finding 
that positive visual imagery during isolation correlates highly 
with (a) intellectual flexibility, breadth, and richness, (b) 
acceptance of one's passive, feminine side, and (c) freedom from 
emotional disturbance and constriction (Holt & Goldberger, 
1961).   
 
       Comparable results in research on individual differences in 
hypnotic susceptibility have seriously undermined long-standing 
interpretations. Specifically, a host of studies recently found 
that hypnotic susceptibility was negatively correlated with 
neuroticism and placebo-responsiveness, and positively correlated 
with emotional stability (Bentler et al., 1963; Lang & 
Lazovik, 1962). Although generally unrelated to specific 
personality attributes in normal subjects, independent work by 
Shor et al. (1962) and As (1963) indicate a consistently high 
relationship between hypnotizability and the frequency of naturally 
occurring altered states, particularly ecstatic and peak 
experiences. The range of personal history experiences 
inventoried in these studies were characterized by constructive 
use of regression, tolerance for logical paradoxes, willingness 
to relinquish ego control, and the ability to suspend disbelief 
or adopt an "as if" attitude. It is worth noting that 
these correlates of hypnotic susceptibility are also associated 
with propitious psychedelic states, certain aspects of 
creativity, and self-actualization. (3)   
 
       Current findings and theorizing in the various areas 
considered here can be summarized briefly.. Whether self-induced, 
stress-induced, or drug-induced, altered states of consciousness 
will be welcomed and valuable rather than feared and harmful to 
the degree that the sociopsychological demands of such 
experiences are congenial to the "kinetic" needs and 
values of a given individual. Based on an analysis of imagery in 
Rorschach responses, Holt and Havel (1960, p.311) reach a similar 
conclusion:   
 
 
    
      We find primary process thinking in conscious subjects 
    either out of strength or out of weakness. In the former 
    case, it is more likely to appear in a playful or esthetic 
    frame of reference, accompanied by pleasant affect. If, on 
    the other hand, primary thinking breaks through the usual 
    defenses uninvited and unwanted, the subject may feel anxious 
    or threatened and is likely to act defensively.   
 
 
       This view is consistent with recent developments in 
personality theory, particularly the current emphasis on latent 
creative potential and self-actualizing tendencies. 
Representative of this trend, the opposing dualisms in 
psychoanalytic theory have undergone major revision so as to 
include regression in the service of the ego and creative fusions 
of primary and secondary process thinking (Hilgard, 1962). In a 
similar vein, Maddi (1963, p. 193) refers to the id as "the 
breeding ground of love and worship, as well as of the novel 
imaginations which are eventually applauded, instituted, and 
cherished by society." Stated simply, recent theoretical 
innovations recognize that greater access to unconscious 
resources is a cardinal feature of psychedelic, creative, and 
other novel perceptual experiences, as well as psychosis. And 
that in contrast to hallucinatory states, creative or revelatory 
experiences involve a temporary and voluntary 
breaking up of perceptual constancies, permitting one "to 
shake free from dead literalism, to re-combine the old familiar 
elements into new, imaginative, amusing, or beautiful 
patterns" (Holt & Havel, 1960, p. 304).   
 
   
PSYCHEDELIC EXPERIENCES AND CONTEMPORARY PSYCHOTHERAPY
 
 
       Consistent with the scene in experimental psychology, a 
similar trend away from viewing psychedelic phenomena as 
undesirable or pathological is also apparent in clinical 
psychology and psychiatry. A growing recognition of the potential 
value of psychedelic experiences is especially discernible in 
contemporary psychotherapy. Recent theorizing in psychotherapy 
reveals an increasing awareness of the restraints imposed by 
conventional modes of thought and perception. As suggested 
earlier, current developments in psychoanalytic theory correct 
the previous over-emphasis on maintaining impulse-control and a 
sharp distinction between self and non-self. Instead, present 
formulations recognize the relative flatness of consensual 
reality as well as the creative potential of novel thoughts and 
impulses. Representative of this trend, the conditions of mental 
health proposed by Heinz Hartmann (1958) include the ability to 
"deautomatize" stereotyped perceptions and the ability 
to maintain fluid subject-object boundaries. It is noteworthy 
that similar attributes have been found to characterize highly 
self-actualized persons. More significantly, a number of studies 
have found that novel states of awareness including loss of 
distinction between self and non-self, transcendental or peak 
experiences, and oceanic feeling states are fairly common in the 
normal college population (As, 1962b; Shor, 1960). Furthermore, 
there has been a greater willingness in recent years to 
acknowledge and report such experiences without apology or 
embarrassment.   
 
       These conceptual revisions and empirical findings also call 
attention to the well-documented shortcomings of orthodox 
therapies and the critical need for more effective techniques. In 
a recent critique of the status of psychotherapy, Colby (1964) 
concludes that our current paradigms have demonstrably failed and 
urges a major transition from ordinary to extraordinary 
innovation. Certainly many therapists readily acknowledge what 
Colby calls an impending crisis. However, Astin (196I) notes that 
"the principle of functional autonomy will permit 
psychotherapy to survive long after it has outlived its 
usefulness." A similar view is expressed by Korn (1964,p.38) 
after examining previous reactions to new methods of treating 
psychopathology.   
 
 
    
      It is notorious that virtually no nostrum has ever been 
    abandoned merely because it failed to work. The old method 
    had always to be overthrown by the newand it is also 
    notorious that the practitioners of the traditional way will 
    attempt to prevent even the first trial of the method on the 
    strange grounds that it has never been tried and 
    provena criterion not applied in their own case.   
 
 
       Despite the reluctance to abandon the old and embrace the 
new, disillusionment with traditional techniques finds expression 
in the current upsurge of interest among therapists of all persuasions 
in Zen Buddhism (Maupin, 1962), existentialism (Lyons, 1961), and 
transcendental or peak experiences (Maslow, 1962). Also 
indicative of present developments is the host of studies 
establishing personal and cultural belief systems as key 
variables in psychotherapy. The representative work of 
Hollingshead and Redlich (1958) demonstrated a significant 
relationship between social class, incidence and type of mental 
illness, and the form of treatment received. The relationships 
found were remarkably consistent with middle-class American 
values. Numerous studies have indicated that improvement in 
therapy involves a basic change in the patient's core belief 
system, that therapists' values influence both the process and 
outcome of therapy, and that in "successful" outcomes, 
the patient's value orientation changes in the direction of the 
therapist's (see, e.g., London, 1964; Schofield, 1964).   
 
       These trends are relevant to what is perhaps the major issue 
in psychotherapy today, namely, the search for positive criteria 
of mental health or personal growth which are explicitly based on 
humanistic values. It is now generally recognized that 
psychological health or self fulfillment involves more than the 
absence of illness or emotional disturbance. These developments 
in mental health concepts have paralleled the recent discovery 
that most recipients of psychotherapy are not suffering from the 
traditional forms of neurosis and character disorder. While 
certainly self-dissatisfied and unfulfilled, the person seeking 
therapy today is generally not unproductive, ineffective, or 
crippled with neurotic symptoms. Many writers have described the 
typical therapy patient as one who is relatively free of physical 
complaints, neurotic anxiety and depression, failures of 
achievement, and interpersonal conflicts (Strupp, 1963). In 
short, the hallmarks of emotional disorder are conspicuously 
absent. Rather, the central struggle for an increasing number of 
successful and relatively well-adjusted people seems to be 
"a loss of meaning in life, an absence of purpose, or a 
failure of faith" (Schofield, 1964). Modern discontent tends 
to take the form of alienation. In William Barrett's terms, 
alienation from God, from nature, from the human community, and 
ultimately, alienation from self (1958). While recognizing that 
the person with problems in personal identity and life outlook 
deserves help, some investigators have concluded that the 
psychotherapist is ill-equipped for such a priestly task 
(Wheelis, 1958). This belief is somewhat substantiated by the 
disappointment which many patients of this type experience in 
psychotherapy. Yet a dearth of alternative resources seem open to 
the person in this predicament.   
 
       In the light then of what seems to be an incompatibility 
between psychotherapy, as traditionally conceived, on the one 
hand, and the nature of modern discontent, on the other, it is 
certainly less than a coincidence that many people who fit this 
description express an interest in the psychedelic experience and 
find their way to LSD. It should perhaps be emphasized that the 
only sentiment these people share with the stereotyped beatnik is 
a sense of alienation from traditional values.   
 
       The attitudes and reactions to LSD, both positive and 
negative, become more understandable when viewed against this 
background of present-day trends in psychology and psychiatry. 
Within this broader context, it is not surprising that the major 
application of LSD today is to treat mental illness rather than produce 
it. Beyond this shift in emphasis, the use of LSD for therapeutic 
purposes clearly reflects the ambivalence among therapists toward 
the ever-growing number of meaning-and identity-seekers who 
request their services. The research and clinical literature 
concerning LSD as a therapeutic agent reveals two major 
viewpoints which seem representative of this ambivalence. These 
two orientations are associated with greatly dissimilar methods 
of administration. One emphasizes the use of LSD periodically and 
in small doses as an adjunct to traditional techniques of 
psychotherapy (Crockett et al., 1963). The other major approach 
employs LSD in a single, large dose, producing an intense and 
prolonged psychedelic experience. Applied in this manner, LSD 
serves as a catalyst for inducing rapid and profound changes in 
the subject's value-belief system and in his self-image (Sherwood 
et al., 1962). While recognizing the therapeutic benefits of LSD, 
this latter technique places greater emphasis on its more unique 
potentialities and value, namely, as a means of facilitating 
personal growth and self-actualization. Rather than freedom from 
emotional symptoms, the primary objective of the psychedelic 
experience becomes a major reorganization of one's beliefs and 
life outlook. In short, the first method is essentially 
illness-oriented, the second, health or growth-oriented.   
 
       When employed as an adjunct to psychotherapy, most 
investigators have associated the beneficial effects of LSD with 
reduced defensiveness, the reliving of early childhood 
experiences, increased access to unconscious material, and 
greater emotional expression. In contrast, when used as a primary 
vehicle for rapid personality change, emphasis is usually placed 
on the transcendental quality of the experience, the resynthesis 
of basic values and beliefs, and major changes in the 
relationship between self and environment.   
 
       With regard to effectiveness, both orientations have reported 
impressive results. Since over three hundred studies have been 
reported, only the most salient and consistent findings will be 
summarized. (4) 
Despite great diversity in the conduct of these studies, high 
improvement rates have been almost uniformly reported, with both 
adults and children, and in group as well as individual 
psychotherapy. Used either as an adjunct or as a primary 
treatment method, LSD has been found to facilitate improvement in 
patients covering the complete spectrum of neurotic, 
psychosomatic, and character disorders. Particularly noteworthy 
are the positive results obtained with cases highly resistant to 
conventional forms of therapy. High remission rates among 
alcoholics, for example, have frequently been reported following 
a single, large dose LSD session. Based on their findings with 
over one thousand alcoholics, Hoffer and his co-workers concluded 
that LSD was twice as effective as any other treatment program 
(1965). Other chronic conditions carrying a poor prognosis which 
have responded favorably to psychedelic therapy include sexual 
deviations, criminal psychopathy, autism in children, and 
adolescent behavior disorders.   
 
       Since most reports have been based on clinical judgments of 
unknown reliability, it is worth noting that comparable results 
have been obtained by investigators in many other countries. 
Furthermore, Freudian therapists, Jungians, behaviorists, 
existentialists, and a variety of eclectic therapists have 
reported positive findings with LSD. It seems safe to conclude 
from the breadth and consistency of the clinical evidence that 
LSD can produce far-reaching beneficial effects in some people, 
under some conditions. However, controlled studies of the process 
variables involved have yet to be conducted. Specifically, in 
what particular ways do various kinds of people respond to LSD, 
both during the experience and afterward? What are the optimal 
conditions of preparation, administration, and follow-up for 
given objectives, and for given subjects? How can we account for 
the various kinds and extent of change which follow an LSD 
experience? In short, despite the mass of accumulated data on the 
outcome of psychedelic therapy, relationships among process 
variables remain obscure.   
 
       Primarily because of the controversy surrounding these 
chemical agents (which interestingly is confined to the United 
States), controlled research aimed at maximizing their safety, 
their effectiveness, and their human value has barely begun. In 
addition to questions concerning the possible uses of LSD as a 
therapeutic or educative device, its potential value as a basic 
research tool for investigating higher mental processes has also 
been minimally explored. Although clinical evidence and 
testimonial reports indicate that LSD promises to be a valuable 
tool for both the study and enhancement of cognitive and 
perceptual functioning, such claims have been neither supported 
nor refuted by means of controlled studies. Other hypotheses 
readily testable include the suggested similarities noted earlier 
between psychedelic, hypnotic, and dream states, the 
inspirational phase of creativity, as well as sensory and dream 
deprivation experiences.   
 
   
PSYCHEDELIC, NADIR, AND PEAK EXPERIENCES
 
 
       The nature, extent, and duration of effects both during and 
subsequent to the LSD-induced state has been a major focus of 
study in the psychedelic research program conducted at the 
International Foundation for Advanced Study, Menlo Park, 
California. Over a three-year period, extensive assessments were 
obtained on almost four hundred subjects before, during, and at 
various points following a psychedelic experience. Each subject 
underwent a single, large dose LSD session conducted in a 
comfortable, aesthetically pleasing setting. Although trained 
staff members were present throughout the session day, primarily 
for emotional support and human contact, no attempt was made to 
direct or interpret the experience. Rather, the subject was urged 
to explore himself and his universe without external guidance or 
intrusion. Prior to the LSD experience, each subject was given a 
physical and psychiatric examination followed by a series of 
preparatory interviews. These interviews were designed to help 
the individual examine or reexamine his reasons for taking LSD, 
to clarify whatever problems or questions he wished to explore, 
and to become accustomed extensive follow-up evaluations were 
made covering a minimum of six months.   
 
       The design of this research program was based on the 
assumption that significant changes would occur along three major 
dimensions; values and beliefs, personality, and actual behavior 
in major life areas. More specifically, it was hypothesized that 
a profound psychedelic experience tends to be followed by a major 
reorientation of one's value system and life outlook. It was 
further hypothesized that this change in basic beliefs would in 
terms be followed by slower alterations in personality as 
well as changes in modal behavior patterns.   
 
       The findings so far provide considerable support for the 
general hypothesis concerning parallel changes in values, 
personality, and behavior (Mogar and Savage, 1964; Savage et al., 
1965a; Savage et al., 1965b). Three days following the LSD 
session, a consistent and reliable increase was found in the 
extent to which an individual agrees with test items reflecting a 
deep sense of meaning and purpose in life, open-mindedness, 
greater aesthetic sensitivity, and sense of unity or oneness with 
nature and humanity. Decreases were found on values pertaining to 
material possessions, social status, and dogmatism. Also 
significant was the finding that changes in personal beliefs 
either remained constant or became still more prominent at later 
follow-ups. These were consistent results cutting across such 
factors as age, sex, religious orientation, or personality type. 
Thus, it seems safe to conclude that a rapid and extensive change 
in values does tend to occur in most subjects, and importantly, 
is maintained over time.   
 
       The additional hypothesis that slower modifications in 
personality and behavior would occur has also received 
considerable support. For example, the data show that if a person 
values human brotherhood more after his psychedelic experience, 
his personality and behavior reflect this new conviction. He 
tends to be less distrustful and guarded with others, warmer and 
more spontaneous in expressing emotion, and less prone to 
feelings of personal inadequacy. With regard to modal behavior 
patterns, parallel changes tend to occur in such areas as marital 
relations and work effectiveness (Savage et al., 1965a).   
 
       Although the overall results indicate that almost all 
subjects derived some degree of benefit along the lines 
hypothesized, it is important to emphasize that the nature, 
extent, and the stability of changes varied considerably. 
Specific sources or correlates of this variability included 
pre-LSD personality structure, the type of presenting problem, 
and variations in the psychedelic experience itself. With regard 
to pre-LSD individual differences, subgroups were objectively 
defined according to (a) personality structure (anxiety 
neurotics, borderline psychotics, nonconforming normals, 
manic-impulsives, and normal depressives), and (b) major defense 
pattern (hysterical, intellectual-compulsive). Despite the 
brevity of the LSD program, all subgroups displayed positive 
personality changes at two and six months following the 
psychedelic experience. The nature and extent of improvement 
compared most favorably with longer-term orthodox therapies 
(Mogar & Savage, 1964).   
 
       Although each subgroup maintained significant improvement, 
subjects varied considerably in their capacity to translate 
profound insights into attitudes, feelings, and conduct. 
Individual differences were particularly apparent at six months 
since by this time a leveling off had generally occurred, that 
is, most subjects had in large part come to terms with their 
rapidly altered self-world image. For six months habitual 
patterns of response to situations had been scrutinized and 
repeatedly challenged. Dissonance between thought, feeling, and 
action had generally been reconciled and a higher level of 
integration achieved At six months some individuals maintained 
and consolidated the gains demonstrated at two months 
(Nonconforming Normals, Manic-Impulsives, Normal Depressives). 
Others displayed further personal growth which was still in 
progress (Anxiety Neurotics, Intellectual-Compulsives). Still 
others showed a tendency to regress from the level of improvement 
indicated at two months (Borderline Psychotics, Hysterics). In 
these subjects, either the pull of well-entrenched maladaptive 
defenses and/or an uncongenial life environment undermined to 
some extent the favorable personality alterations demonstrated 
earlier.   
 
       With regard to the nature of changes characterizing different 
personality types, shifts tended to occur consistent with the 
symptoms and defense pattern of a given group. Anxiety neurotics 
were less anxious, compulsive, and withdrawn while close 
relationships were more gratifying. In contrast, impulsive, 
hyperactive subjects led a more orderly, less hectic existence 
and displayed greater impulse control.   
 
       The "illness-oriented" nature of these findings 
reflects the fact that two-thirds of the total sample resembled 
the typical case load of an outpatient psychiatric clinic. The 
remaining one-third did not present complaints of a psychiatric 
nature and revealed minimal emotional disturbance according to 
both diagnostic evaluation and psychological test data. Instead, 
the interest expressed by these subjects seemed to be 
"growth-motivated" rather than 
"deficiency-motivated." Some were dimly aware of 
potentialities which they hoped to activate and develop more 
fully. Others expressed a feeling of emptiness and lack of 
meaningful purpose while adequately meeting the exigencies of 
life. Still others sought a deeper understanding or more 
satisfying resolutions to problems of an existential nature.   
 
       As a result of their stable life circumstances and relative 
freedom from neurotic disturbance, these subjects were more 
likely to grapple with ultimate problems during the LSD 
experience. In addition to self-identity and personal worth, 
questions of love, death, creation and rebirth, and the 
resolution of life paradoxes received frequent attention. Unlike 
the neurotic group, childhood memories, intrapsychic conflicts, 
and specific interpersonal relations were explored minimally. 
Accounts of the experience written shortly afterward revealed 
that healthier subjects were less likely to view the psychedelic 
state as fantastic or totally dissimilar from previous 
experience. These personal reports together with clinical 
evaluations and ratings also indicated that this group benefited 
considerably from the psychedelic experience along the lines of 
self-actualization, richer creative experience, and enhancement 
of specific aptitudes and talents. At the present time, these 
tentative findings are being investigated more objectively with 
measures appropriate for a normal sample. Thus it will be 
possible to compare individuals, differing in personality and 
presenting problems, with regard to health-growth dimensions as 
well as decreases in pathology.   
 
       Since most subjects in this series of studies were college 
trained and psychologically sophisticated, it is noteworthy that 
the frequency of occurrence of transcendental-like experiences is 
apparently as great in "naive" prisoners and alcoholics 
(Unger, 1964a). Such communalities are not surprising in view of 
the key role placed by universal and personal symbolism in 
psychedelic experiences and the relatively weak role of the 
conscious self (including verbal facility, accumulated knowledge, 
and intelligence). What seems to be affected by 
subject-differences is the content of the experience, rather than 
its form, intensity, or profundity.   
 
       Differences in the thematic content of the experience were 
found among subjects with diverse cultural backgrounds. For 
example, wide individual differences were demonstrated with 
respect to content in the frequent experience of unity. However, 
the fact that the majority of subjects experienced a sense of 
unity or oneness seems far more significant than whether the 
unity was felt with self, nature, the universe, God, or some 
combination of these. This is merely another way of saying that 
to the degree an individual can verbalize the experience, he will 
draw on his own particular semantic framework and belief system. 
One can only speculate on the discrepancy between this 
communicated account of the experience and the experience itself. 
  
 
       These findings suggest that the profundity or intensity of a 
psychedelic experience is more crucially related to subsequent 
change than thematic content. More specifically, the hypothesis 
currently being tested is that subsequent transformations in 
values, personality, and conduct are a function of the 
experience's intensity, either positive or negative-or both. In 
other words, painful experiences can be as personally revealing 
and permanently beneficial as experiences of great joy and 
beauty.   
 
       The hypothesis that a profound and intense psychedelic 
experience, regardless of its emotional valence, can serve as a 
catalyst for rapid personal growth is consistent with current 
interpretations of both nadir and peak experiences. Concerning 
nadir experiences, Erikson's brilliant analysis of the 
post-adolescent identity crisis (1959) has recently been extended 
to include periodic "crisis of maturation" (Kahn, 
1963), naturally occurring "desolation experiences" 
(Laski, 1961), and the therapeutic value of "existential 
crises" (Bugental, 1965). In each case, these writers 
emphasize that although negative and painful, a personal crisis 
is: (a) not pathological, (b) a critical choice point in life 
necessitating a "leap of faith," (c) an essential 
condition of growth and psychological change, and (d) often a 
catalyst for an emerging inner conviction or new awareness. The 
potential value of nadir experiences has been well-stated by 
Forer (1963, p.280): "Crisis as a psychological experience 
is a part of any creative effort, scientific, artistic, 
therapeutic, or inter-personal."   
 
       With regard to positive revelatory experiences, Maslow 
recently developed the thesis that experiences referred to as 
religious, mystical, or transcendental actually denote special 
cases of the more generic "core-religious" or peak 
experience, described as the hallmark of highly self-actualized 
people (Maslow, 1964). Similarly, the extensive research on 
creativity by MacKinnon and his associates indicates that the 
truly creative person is distinguished from the noncreative 
individual by his capacity for "transliminal 
experience" (MacKinnon, 1964). Following Harold Rugg's study 
of creative imagination, the transliminal experience is 
characterized by an illuminating flash of insight occurring at a 
critical threshold of the conscious-unconscious continuum. 
MacKinnon's description of the transliminal experience bears a 
striking resemblance to the more inclusive peak experience. 
Interestingly, Maslow (1964) suggests that psychedelic drugs may 
offer a means of producing a controlled peak experience under 
observation, particularly in "non-peakers."   
 
       Although tentative at this point, these lines of 
investigation seem highly significant and certainly suggestive of 
future directions in LSD research. And if the historical 
perspective described earlier is relatively accurate, the 
exploration of ways of expanding human consciousness will soon 
occupy a prominent position in the mainstream of contemporary 
psychology. Should this prediction materialize, we can look 
forward to a far more extensive application of these powerful 
agents as a means of facilitating social as well as individual 
potentialities. For the present, research with the psychedelics 
will continue to seek those conditions which maximize their 
safety, their effectiveness, and their human value.
