The purpose of this study was to determine whether antisocial preadolescent children display more stimulation seeking than normals or neurotics in a situation intentionally designed to be boring. (Author)

The purpose of the present investigation was to extend previous findings in three areas, further relating hemisphericity to psychopathology. Based on the findings relating hemisphericity to psychopathology and to classroom seating, it was expected that there would be a relation between classroom seating and psychopathology. (Author)

This study investigated the hypothesis that fears are attitudes and can be reduced through the use of positive reinforcement. (Author)

The current study is concerned with developing a procedure designed to maximize subject attention to the written information while minimizing potentially confounding boredom or fatigue factors and second to cross-validate previous studies employing written information to modify performance with an improved experimental procedure.

Article investigated the psychological characteristics of chronic primary insomniacs (persons who show no major psychological or medical problems other than long-term difficulties with sleep). (Author/RK)

This study investigated the possibility of employing mildly mentally retarded residents to observe the mealtime behaviors of lower level mentally retarded residents. Then these residents were employed as reinforcing agents, to determine if a retarded "trainer" could modify the observed mealtime behaviors within a multiple baseline design.…

Previous studies have shown a low rate of engagement in pleasant activities to be a concomitant of depression. The crucial question addressed by the Hammen and Glass study (1975) is whether an increase in pleasant-activity level will produce a decrease in depression level. (Editor)

Thirty three college students were arbitrarily given a number of electric shocks by an experimental partner for incorrect answers. Similarity between S and partner was then manipulated. The instigation to self-aggression is apparently greatest when high similarity is perceived between self and attacker. (Author/MF)

Similarity of impairment in naturally occurring depression and laboratory-induced, learned helplessness was demonstrated in college students. (Editor)

The present study attempted to deprive human subjects of dreaming through the administration of a posthypnotic suggestion and to increase or facilitate dreaming through a second suggestion that was used with another group of subjects. (Author/RK)

A carefully controlled comparison of the personality characteristics of heroin addict (n=27) and nonaddict (n=20) offenders was carried out so as to avoid methodological problems associated with earlier studies. (Editor)

These studies constituted attempts to determine whether and to what extent the problems exhibited by children with learning disabilities are due to dysfunction at the level of the cerebral hemispheres. (Author)

The goal of the study described here was to learn more about dream content in patients who had recovered from serious depression. The question was asked whether these formerly depressed patients still showed depressive traits in their nocturnal dreams, even though their daytime behavior and mood now approached entirely normal levels. (Author)

This paper is written to propose and describe a set of four criteria for the empirical evaluation of psychiatric classification. (Author)

Three theoretical viewpoints have dominated the recent empirically oriented literature on depression: Beck's cognitive view, Seligman's helplessness model, and Lewinsohn's theory implicating a low rate of response-contingent reinforcement. Here each theory is evaluated individually interms of its empirical support and adequacy as a theory and all…
