This study examined psychoanalytic, physiological, and social learning models of depression in terms of etiology and symptomatology. Emphasis was placed on social learning theories of depression. First, Beck's cognitive approach stated that the root of depression was a negative cognitive set. Depressive episodes might be externally precipitated, but it was the individual's perception and appraisal of the event that rendered it depression inducing. Secondly, Seligman's learned helplessness model explained reactive depression in terms of a belief in one's own helplessness. Specifically, Seligman stated belief in the uncontrollability of outcomes resulted in depression, irrespective of the correspondence of such beliefs to objective circumstances. Additionally, depression resulted from noncontingent aversive stimulation and noncontingent positive reinforcement. Thirdly, Lewinsohn's model was based on these assumptions: a low rate of response-contingent positive reinforcement which acted as an eliciting stimulus for depressive behaviors. This low rate of response-contingent positive reinforcement constituted an explanation for the low rate of behaviors observed in the depressive. Total amount of response—contingent positive reinforcement is a function of a number of events reinforcing for the individual, availability of reinforcement in the environment, and social skills of the individual that are necessary to elicit reinforcement.

The assumption that EMG biofeedback cultivates an antistress response was tested under stress conditions while investigating the comparative efficacy of low versus high arousal treatment strategies. Biofeedback-assisted, cue-controlled relaxation training was used as the low arousal treatment strategy for half of the 20 normal subjects used in the study. The other half received a high arousal treatment strategy which used the same training in combination with an avoidance conditioning procedure. In this procedure mild electric shock was used as contingent aversive stimulation designed to reinforce relaxation responses. Both groups received four in-lab training sessions with a 4-day interim of home practice of cuecontrolled relaxation prior to the last in-lab training session. Pretraining assessment consisted of four 10-minute periods of alternating no-stress and stress conditions. Mild electric shock and loud tones were used as stressors. Posttraining assessment was identical to pre training except subjects employed self-directed, cue-controlled relaxation rather than self-directed relaxation based on instructions without training. Frontal EMG, subjective mental and muscle tension ratings, and behavioral observations of relaxation behavior served as dependent measures during pre- and posttraining assessment. EMG readings were used during in-lab training and the two subjective rating scales were used during home practice.

Hypnotic susceptibility, often regarded as a relatively stable individual characteristic, has been found to be related to the personality dimension of absorption. To test the hypothesis that this relationship is a function of the nature of the sensory response to stimulus events and the development of cognitive models pursuant to the processing of that information, a group of hospitalized, chronic pain patients were assessed on the following dimensions: absorption, clinical hypnotic responsiveness, cognitive resistance to interference, and visual automatization.

A group of 44 high-orgasm-consistency and 34 low-orgasmconsistency women were administered the Harvard Group Scale of Hypnotic Susceptibility, a Sexual Behavior Questionnaire, and the Fall Back Task. Excitatory and inhibitory controlling attitudes as manifested in hypnotic susceptibility, reported control of thinking and movement during coitus, causal attributions, and attitude toward alcoholic beverages were related to orgasm consistency. Women experiencing expectancy disconfirmation for coital outcomes attributed outcomes to unstable factors, supporting the application of Weiner's achievement model to the domain of coital orgasm. High and low consistency women showed different patterns of causal attribution for coital outcomes. High consistency women's attributions fit their reported sexual experiences, while low consistency women's attributions suggested the presence of self-esteem enhancing cognitive distortions.
