Multivariate analysis of the interaction of person,situation and response variables in situation-specific interpersonal behavior

This study attempted to use multivariate statistical methodology to empirically derive and define person, situation and response variables which interact in determining situation-specific behavior of college students, and to clarify the nature of the interaction of those variables. A variant of principal components analysis was used to derive reliable dimensions of persons and situations underlying situation-specific self-reported response. These dimensions appeared to correspond to clusters of grossly similar situations. An attempt to define the derived dimensions using measures based on Murray needs did not provide clear-cut, quantitative definitions. The solution derived using the principal components procedure was found to have validity in terms of predicting overt behavior in a contrived situation. Results were interpreted as being supportive of the principal components technique as a method for deriving determinants of situation-specific behavior, but the need for new technology for defining those dimensions was commented upon.     

The rorschach assessment of borderline defenses: a concurrent validity study

This study assesses the concurrent validity of two Rorschach defense scales designed to identify borderline defensive structure. A Rorschach scale designed by Cooper and his colleagues was systematically compared to a defense scale constructed by Lerner and Lerner. Despite considerable overlap on a conceptual and operational level, the scales are based on divergent theoretical models (developmental arrest and fixation) and Rorschach units of analysis (all responses and human responses). Our results are based on the capacity of each scale to discriminate between independently diagnosed samples (neurotic, outpatient borderline, inpatient borderline, schizophrenic) and the relative discriminatory power of particular defenses within each scale to differentiate between groups.     

Depletion of brain norepinephrine with DSP-4 does not alter acquisition or performance of a radial-arm maze task

The acquisition of a radial-arm-maze task was unimpaired following administration of DSP-4, a selective noradrenergic neurotoxin. Maze performance remained unaffected when 5- or 30-min delays were imposed between the fourth and the fifth arm selection. Neurochemical analysis performed 90 days after injection revealed that DSP-4 significantly decreased concentrations of norepinephrine in the hippocampus, cortex, and cerebellum. The regional concentrations of dopamine and serotonin were not affected. These data are consistent with previous reports demonstrating that depletion of brain norepinephrine does not impair spatial learning and memory.     

Memory-enhancing characteristics of client-recalled important events in cognitive and experiential therapy: Integrating cognitive experimental and therapeutic psychology

In an attempt to encourage further integrative theorizing and experimental work across cognitive and therapeutic psychology, characteristics of therapeutic events that might contribute to their ‘memorableness’ were examined. Scales that rate five ‘information processing’ characteristics of therapeutic events were employed to score such characteristics of 55 client-identified important and 55 matched control events taken from actual therapeutic sessions of both cognitive and experiential psychotherapies. Results indicated that scales scoring the ‘depth’, ‘elaborateness’, and ‘conclusion-orientation’ of therapeutic dialogue during the events examined tended to discriminate reliably and as predicted between client-identified important and control events, particularly when ratings of therapist talking turns were examined. Limited support also was found for a second prediction based on Paivio's (1986) dual coding theory of memory concerning different patterns of results for cognitive versus experiential therapeutic events. Suggestions are offered for further research on human memory for specific events in therapeutic and other areas of applied psychology.
