A.R. luria's contribution to the study of the verbal control of behavior

Summary This paper examines Luria's contribution to research on the verbal control of behavior, which spanned from the 1930s to 1962. The speechmotor method utilized in the original Soviet experiments is reviewed, and the central methodological issues discussed. The internalization of speech is suggested as a theoretical problem yet to be adequately explained in cognitive or behaviorist theory.     

An investigation of the arousal model of interpersonal intimacy

In a study designed to test Patterson's arousal model of nonverbal intimacy, the heartrate, gaze, smiles, body orientation, and body lean of each of 40 female subjects who interacted with an accomplice were measured. Within a factorial design, subjects were induced to view more or less favorably the accomplice, who subsequently increased or maintained the same level of nonverbal immediacy as she did in an earlier session. It was hypothesized that (1) an increase in the accomplice's immediacy would effect an increase in subjects' arousal (heartrate) which, in turn, (2) would lead to either reciprocal or compensatory nonverbal adjustments by subjects, depending on whether they viewed the accomplice more or less favorably, respectively. The results supported the first but not the second hypothesis. However, interpretation of the results suggests, nevertheless, that they may be consistent with the arousal model.     

Interactive effects of generalized and situational expectancies on the arousal of cognitive and emotional components of social anxiety

This study examined the arousal of social anxiety in an interview setting as a function of anticipated self-disclosure. Of 88 college students who completed the Social Avoidance and Distress (SAD) scale and other measures of social anxiety, self-disclosure, need to affiliate, and interpersonal trust, 24 volunteered for the interview. During the interview, both components of anxiety (worry and emotionality) were affected by expectancy conditions, and emotionality was higher for high- than for low-SAD subjects. The prediction of an interaction between SAD level and expectancy condition on worry was confirmed: only high-SAD subjects exposed to the negative-expectancy condition experienced significant elevations in worry. Though social anxiety and self-disclosure measures correlated negatively, anxiety did not affect self-disclosure during the interview.     

Behavioral assessment of imipramine effects in a depressed child

A 7-year-old boy was diagnosed as suffering from childhood depression by two independent psychiatric evaluators who employed the Research Diagnostic Criteria. Multifaceted behavioral observations were performed on target behaviors which were identified as major problematic areas of functioning related to the child's depression. The behavioral assessment strategy included daily monitoring of on-task and disruptive behavior in the classroom, enuresis, and overall hygienic, social, and compliance behaviors as a means of identifying the specific drug-induced effects of an anti-depressant, imipramine. The assimilation and application of behavioral assessment strategies within child psychiatry have been slow and tenuous. Reasons for the resistance include theoretical differences and misconceptions among psychiatric personnel, who, although open to objective evaluations, may wish to employ nonbehavioral treatments such as pharmacologic agents. The primary purpose of this study was to demonstrate the viability of behavioral assessment as an integral adjunct to pharmacologic treatment in a psychiatric setting as a means of gauging the efficacy of a psychiatric intervention. Issues regarding the role of behavioral assessment in psychiatry and, in particular, pharmacologic interventions with depressed children are examined and discussed.This study was supported, in part, by NIMH Grant MH 30915.     

The relationship between arousal and positive self-presentation

Investigated the validity of the hypothesis that subjects would experience arousal if they received information suggesting that they were presenting themselves to others in a negative manner. Twenty-seven subjects were randomly assigned to a control, evaluation apprehension, or negative feedback group. Subjects' heart-rate was continuously monitored as subjects' rated a series of photographs. Subjects in the evaluation apprehension group were given a cue as to how to present themselves positively whereas subjects in the negative feedback group were told, following their response to the 15th photograph, that their responses suggested maladjustment. Heart-rate change above a baseline measure revealed that an increase in heart-rate occurred only when subjects were informed that they were transmitting negative information. Such a finding supports a positive self-presentation explanation of subject motives in the psychological experiment.
