A test of subliminal symbiotic activation as a means of alleviating depression.

Thirty-six depressive subjects were randomly assigned to one of three treatment groups. Group 1 subjects received 60 subliminal presentations of a slide of two figures and the words MOMMY AND I ARE ONE for male subjects and DADDY AND I ARE ONE for female subjects. Group 2 subjects received 60 subliminal slide presentations of a single figure with the words PEOPLE ARE WALKING. Group 3 subjects did not receive a slide. A pretest and posttest Beck Depression Inventory was administered to assess depression increase or decrease. The "subliminal" therapy was carried out over four different sessions. The data show that Group 1 subjects significantly reduced depression scores from pretest to posttest, whereas the subjects in Groups 2 and 3 did not reduce depression scores. Discussion is centered on comparisons of the data with past findings. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Affective priming with subliminally presented pictures.

Affective priming studies have demonstrated that subliminally presented prime words can exert an influence on responses towards positive or negative target stimuli. In the present series of experiments, it was investigated whether these findings can be extended to pictorial stimuli. Ideographically selected positive, neutral, and negative picture primes that were sandwich-masked immediately preceded positive or negative target pictures (Experiment 1) or words (Experiments 2 & 3). Evaluative categorization responses to these target stimuli were significantly influenced by the valence of the prime. First, it was demonstrated that high anxious participants were selectively slowed when the subliminally presented prime was negative (Experiments 1 & 2). Second, the affective congruence between primes and targets also exerted an influence on the responses, but in a direction that is opposite to what is typically observed in affective priming research. These reverse priming effects are situated within a series of recent similar findings, and implications for theories of affective priming are discussed.

Effects of subliminal sympbiotic gratification and the magic of believing on achievement.

The present experiment examined the effect of a subliminally presented symbiotic gratification and a magic of believing message on academic achievement. Graduate students were randomly assigned to one of the two experimental message conditions, or to a control message condition, and received on the average 12 sessions, 10 exposures per session, of 4-msec visual subliminal presentation of one of the three messages. Each session occurred immediately prior to a lecture in either a statistics or a measurement class. Each of the courses was taught in a traditional manner by the regular faculty, who were naive regarding the experimental conditions. Objective final examinations for each course revealed statistically significant differences in favor of the symbiotic gratification experimental condition over the control condition. No differences were obtained between the symbiotic and magic of believing conditions. Research and clinical implications of the findings are also explored.

Incidental stimulation: A study of preconscious transformations.

Continuing the studies from the NYU Research Center for Mental Health on the effect of subliminal stimuli upon perception, the examiner tests the effect of such auditory stimuli upon the production of fantasy, in this instance, inventive stories. Fantasy stories subsequent to exposure to subliminal speech were analyzed in terms of symbolic representations or transformed derivatives of the original stimuli. The result generally confirms the effect of subliminal stimulation on thinking and the findings are related to the psychoanalytic theory of primary and secondary thinking. 20 refs.

Subliminal stimulation: A pervasive problem for psychology.

After a brief historical introduction and a discussion of methodological issues, this substantive review concentrates upon the relevant literature of the past 5 years. Special attention is given to the writer's own experiments on the effect of subliminal anchors upon psychophysical judgments. (67 ref.)

On becoming ready to pursue a goal you don't know you have: Effects of nonconscious goals on evaluative readiness.

Findings showed that the nonconscious activation of a goal in memory led to increased positive implicit attitudes toward stimuli that could facilitate the goal. This evaluative readiness to pursue the nonconscious goal emerged even when participants were consciously unaware of the goal-relevant stimuli. The effect emerged the most strongly for those with some skill at the goal and for those for whom the goal was most currently important. The effect of implicit goal activation on implicit attitudes emerged in both an immediate condition as well as a delay condition, suggesting that a goal rather than a nonmotivational construct was activated. Participants' implicit attitudes toward a nonconscious goal also predicted their goal-relevant behavior. These findings suggest that people can become evaluatively ready to pursue a goal whenever it has been activated--a readiness that apparently does not require conscious awareness or deliberation about either the goal or the goal-relevant stimuli. Theoretical implications of this type of implicit goal readiness are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
