Investigations of the reinstatement of extinguished fear

In two experiments, fear was conditioned to the situational cues in one compartment of a hurdle-jumping apparatus and was then extinguished. Subsequently, either one shock (Experiment 1) or three or nine shocks (Experiment 2) were given in a situation distinctively different from that in which conditioning and extinction had taken place. Although some associative strength between the situational cues and fear was shown to have remained after extinction, in neither experiment did the postextinction-shock treatment increase the fear elicited by these cues: Escape-from-fear performance was no better in the shocked groups than in control groups given no additional shock. Thus, the nonassociative hypothesis which postulates that inflating the value of the representation of the UCS with shock-alone presentations can reinstate the extinguished fear of a stimulus was not supported. Rather, the results showed that, after extinction, an increase in fear of a simulus depended on further conditioning to that stimulus. The data also indicated that the nonvisual components of the situational cues predominated over the visual component.     

Neuropsychiatric and experiential correlates of violent juvenile delinquency

This article reviews evidence regarding contributions of neuropsychiatric and psychological vulnerabilities to violent delinquency, and the interaction between intrinsic vulnerabilities and experiential factors in the genesis of antisocial juvenile behavior. Consideration is given to biochemical and physiological factors, genetics, medical status, and neurological, psychiatric, and neuropsychological factors. Implications for treatment are discussed.     

The ontogeny of hemispheric specialization: some old hypotheses revisited

This paper re-examines two hypotheses on the ontogeny of hemispheric specialization that long ago fell into disfavor in neuropsychology. It is argued that these hypotheses, equipotentiality and progressive lateralization, may have suffered from misinterpretation that fostered premature acceptance of the developmental invariance view of hemispheric specialization. An alternative view is presented that incorporates both hypotheses within a neurodevelopmental context using anatomical (postmortem) and childhood aphasia data.     

Research on working women: A report card of 22 journals

The study was part of an official project of the Women in Management Division of the Academy of Management to examine the status of research in gender issues in organizations. It specifically looked at 22 major scholarly and trade journals plus the Proceedings of the Academy of Management for the six-year period of 1983–1988 to determine quantity, patterns, and trends in publication of research on issues of interest to the domain of the division. Results show a downward trend in gender-issue publication at a time when working women are becoming an ever-increasing percentage of the work force. This is particularly true of the so-called prestige journals. Psychology journals accounted for 64% of the total, management 13.4%, personnel 19%, and Proceedings 3.5%. Implications for research and careers are discussed.A shorter, less-complete version of this paper was presented in summary form at the annual meeting of The Academy of Management in Washington, DC, August 1989 as part of a symposium for the Women in Management Division.     

Contributions of the care-giving role to women's development

It was hypothesized that older widows (N=309) who had been care givers to their husbands would have undertaken a greater number of household responsibilities than had women who had not been care givers. Findings indicated that, prior to the husband's death, more traditionally male and more traditionally female tasks were performed by the care-giving wives (n=158). This was particularly true in the case of Alzheimer's care givers (n=21). More importantly, widows' present feelings of competence were related to undertaking household responsibilities, with those who had been care givers expressing significantly higher levels of competence.     

The response of day and night wetting children and children who wet only at night to retention control training and the enuresis alarm

Forty-five children with night wetting only (NW) and 30 children with day and night wetting (DNW) were randomly assigned to 2 treatment groups: alarm only and alarm preceded by 4 weeks of retention control training (R.C.T.). Fewer children became dry at night in the DNW group than the NW group and DNW children relapsed earlier following treatment. The enuresis alarm was far superior to R.C.T. in reducing night wetting in both enuretic groups. It also reduced day wetting in some of the DNW children. Children who became dry in the NW group did not show significant changes in functional bladder capacity. Although changes in functional bladder capacity were seen in the DNW children who became dry, changes were only noticeable once dryness had been achieved.     

Perceptions of male and female success or failure in relation to spouse encouragement and sex-association of occupation

Male and female subjects read four paragraphs portraying successful (experiment 1) or unsuccessful (experiment 2) males or females in masculine or feminine occupations, with a supportive or nonsupportive spouse. The likelihoods of various conflicts, consequences, and causes of the success or failure were rated. Generally, ratings of more negative consequences were associated with lack of spouse support for a career pursuit. Spouse support influenced perceptions of female more than male success. The sex-association of the career proved to be an important determinant of perceptions of conflict, consequences, and attributions for the success or failure. Although male and female occupations had been equated for status, female jobs appeared to be generally devalued relative to male jobs.     

Does echoic memory develop?

A series of experiments is reported on the stimulus suffix effect with the primary variables being age of the subject (7 and 11 years), rate of presentation, and list length. While the suffix effect was larger for younger subjects at a slow rate of presentation, the effect was nearly identical across age groups with a fast presentation rate. It was concluded that when the contaminating effects of more central processes are reduced, there is no developmental change in the capacity of echoic memory. An interesting effect of rate of presentation is reported with younger subjects performing better at faster rates of presentation and adults performing better at slower rates.     

Attitudes and duration of unemployment among sixteen-year-old school-leavers

Research is reported which looks at the possibility of using attitude measures to identify, before they leave school, those low-attaining pupils at risk of longer periods of unemployment, and therefore in particular need of support, information and skills. Two independent assessments of attitudes were used: ratings by class teachers, and attitude scales. Findings were largely negative: we cannot predict, through the use of attitude measures alone, which pupils will take longest to find jobs. A variety of other factors influencing duration of unemployment are discussed, together with some implications for careers teaching in schools.
