Forty-seven heroin addicts being treated at the New York VA Methadone Clinic were divided into an experimental and a control group. In addition to the regular methadone treatment program, both groups received subliminal exposures to a verbal message for 24 sessions (4 times a week for 6 weeks). The messages were MOMMY AND I ARE ONE (experimental) and PEOPLE ARE WALKING (control), administered under double-blind conditions. In keeping with the main hypothesis, the experimental subjects, when compared with controls, showed a greater decrease in their use of heroin and other illicit drugs during the postintervention period. Additionally, on a follow-up questionnaire, the experimental subjects reported being more in control of their drug habits and more effective in their work than did those in the control group. Also, analysis of the patients' reported dreams revealed that the experimental group had more dreams containing positive interactions with a significant woman or son than did the control group.

An experiment was performed to test the hypothesis that an unconscious conflict between a wish to attain symbiotic oneness with another person on the one hand and personal independence on the other, should be weakened by alcohol if the main effect of intoxication is to reduce the strength of psychological inhibitions. In turn, a reduction in such conflicts should improve motor performance. Data indicated no such effects, and it was concluded that the disinhibition hypothesis as an explanation of alcohol-related behavior was not supported.

The paper summarizes the results of studying the effects of subliminal stimulation of the basolateral part of the amygdala nuclei complex on alimentary secretory conditioned and unconditioned reflexes (11 dogs, 150 tests of low-frequency and 95 tests of high-frequency stimulation). It has been found that stimulation of the basolateral amygdala taking part in the inhibitory system of alimentary behaviour control may exert not only inhibitory but also activating influences on the alimentary secretory reaction. The inhibitory effects are, however, much stronger than the activating ones, particularly with low-frequency stimulation. Subliminal stimulation of the basolateral amygdala affects dissimilarly inborn alimentary reactions and conditioned, acquired reactions. Conditioned secretory reactions in most cases (up to 80% of the tests) are inhibited, while unconditioned ones, are activated. It is suggested that the amygdala plays a different role in these two types of reactions.
Research has shown that subliminal presentation of MOMMY AND I ARE ONE (MIO) can help improve adaptive functioning. Two experiments tried to determine whether changes in mood, especially free-response mood, could help explain these findings. In one experiment, 20 men were randomly assigned to receive either a subliminal MIO or control stimulus. Results showed predicted effects on a free-response and no effects on a self-report mood measure. In the other experiment, 54 male subjects randomly received one of three subliminal stimuli. They evidenced the same pattern of mood results. Sentential semantics were shown to be relevant to the obtained results. Ascending threshold and 150 forced-choice discrimination trials demonstrated that subjects could not report stimulus content. It was concluded that MIO effects were attributable to unconscious processing of the entire message and that free-response mood may partly mediate these effects. Suggestions for future research were offered.

Thirty schizophrenic patients were seen individually for three sessions in a balanced design. In each session, following subliminal stimulation with a neutral stimulus, a baseline assessment of pathology was made. Then, in different sessions, in counterbalanced order, each patient received one of three experimental (or "critical") stimuli: a) a neutral control stimulus; b) a message--CANNIBAL EATS PERSON--intended to activate aggressive ideation; c) a message--I AM LOSING MOMMY--intended to activate fantasies of object loss. Each of these conditions was followed by an initial and later assessment of pathology, and finally by a measure of the patients' sense of differentiation from a mothering figure. In the final session other measures were also obtained, including each patient's conscious association to the critical stimuli when presented supraliminally. The major results were: a) as in previous experiments, the subliminal aggressive message intensified pathology and aggressive ideation--especially for relatively undifferentiated and relatively nondefended patients; b) subliminal stimulation of fantasies of object loss also increased pathology--especially for nondefended patients--and also increased the patients' sense of merging with the mothering object; c) the patients' response to subliminal stimuli--including presumably neutral ones--was a function of the conscious meaning(s) of such stimuli. It was concluded that: a) the threat of object loss (real or fantasied) may be one of the motivations supporting the development of pathology in schizophrenics; b) the activation of fantasies of aggressive destruction can exacerbate schizophrenic pathology--perhaps by activating fantasies of object loss; c) future research with subliminal stimulation should consider carefully the differential responsiveness of subjects to the content of particular messages.

This investigation further examined the effects of activating unconscious symbiotic fantasies in schizophrenics. One hundred twenty-eight hospitalized schizophrenic men who qualified as "relatively differentiated" on the Adjective Rating Scale were randomly assigned to four groups. Each group was assessed for pathological thinking, pathological nonverbal behavior, and self-esteem before and after the subliminal exposure of an experimental and control stimulus. The control stimulus for all groups was the message PEOPLE ARE WALKING and the experimental stimuli were the messages MOMMY AND I ARE ONE, MOMMY IS ALWAYS WITH ME, MOMMY FEEDS ME WELL, and I CANNOT HURT MOMMY (one for each group). One half of each group was subliminally exposed to verbal messages only and one half to verbal messages accompanied by congruent pictures. The first stimulus (MOMMY AND I ARE ONE) was intended to activate unconscious symbiotic fantasies that in a number of prior studies reduced pathology in groups of relatively differentiated schizophrenics. The other stimuli were intended to activate reassuring unconscious fantasies about "mommy" that were not specifically symbiosis-related. Only the MOMMY AND I ARE ONE stimulus led to more adaptive behavior and did so on all three dependent variables. This supported the supposition, also borne out in two other studies, that it is specifically symbiosis-related gratifications that are ameliorative for schizophrenics. The above results were considerably stronger for the subgroup that was exposed to a picture accompanying the MOMMY AND I ARE ONE message. This was viewed as probably the result of the pictorial representation serving as a concretization of the more abstract verbal message and as such being more relevant to the relatively primitive mode of thinking in schizophrenia.
