What is the central feature of extraversion? Social attention versus reward sensitivity

R. E. Lucas, E. Diener, A. Grob, E. M. Suh, and L. Shao (2000) recently argued that the core of the personality dimension of Extraversion is not sociability but a construct called reward sensitivity. This article accepts their argument that the mere preference for social interaction is not the central element of Extraversion. However, it claims that the real core of the Extraversion factor is the tendency to behave in ways that attract social attention. Data from a sample of 200 respondents were used to test the 2 hypotheses with comparisons of measures of reward sensitivity and social attention in terms of their saturation with the common variance of Extraversion measures. The results clearly showed that social attention, not reward sensitivity, represents the central feature of Extraversion.     

Big five factors and facets and the prediction of behavior

The authors compared the Big 5 factors of personality with the facets or traits of personality that constitute those factors on their ability to predict 40 behavior criteria. Both the broad factors and the narrow facets predicted substantial numbers of criteria, but the latter did noticeably better in that regard, even when the number of facet predictors was limited to the number of factor predictors. Moreover, the criterion variance accounted for by the personality facets often included large portions not predicted by the personality factors. The narrow facets, therefore, were able to substantially increase the maximum prediction achieved by the broad factors. The results of this study are interpreted as supporting a more detailed approach to personality assessment, one that goes beyond the measurement of the Big 5 factors alone.     

What Price Attractiveness? Stereotype and Risk Factors in Suntanning Behavior

Two experiments examined stereotype and risk factors in suntanning. In the first, subjects formed more positive impressions of a target described as having a suntan than of a control target. Ratings were not as positive, however, if the tan was portrayed as having been intentionally sought. A negative facet to the tan stereotype, in terms of perceived vanity, was also observed. In the second, subjects observed a videotape documenting the risks associated with sun exposure either before or after responding to a questionnaire dealing with attitudes and beliefs about suntanning. The results were consistent with the interpretation that the tape influenced observers in the direction of perceiving a tan as less attractive and enhancing their concern about the dangers of tanning. Subjects displayed the "optimistic bias" effect (Weinstein, 1980) in their estimated likelihood of getting skin cancer. While those with higher reported tan levels were more likely to endorse the attractiveness stereotype associated with a suntan, there was minimal evidence that these individuals were apprehensive or concerned about the risk factors. Their responses to a number of items suggested a measure of resistance or denial. Women generally indicated greater awareness and concern about risks than did men. The results of both studies suggest the important role played by images perceived to be associated with suntanning. In the context of mounting evidence regarding the carcinogenic properties of sun exposure, implications for changes in tanning behavior were considered.     

Effects of gender and gender role identification of participant and type of social support resource on support seeking

The relationship between type of social support resource (emotional vs. instrumental support) sought and gender and gender role identification was examined. Gender-typed and androgynous, white, middle to upper middle class males and females were given scenarios describing situations in which help was needed, and which also identified a female helper who would provide either emotional or instrumental support. The results indicated that males reported a significantly lower likelihood of seeking emotional support than instrumental support, while no significant differences were found between levels of seeking emotional and instrumental support for females. In comparing men and women for each type of support, it was found that males reported a significantly lower likelihood of seeking emotional support than did females. In addition, gender-typed males reported seeking emotional support significantly less than did the other three groups: androgynous males and females, and gender-typed females.This article was derived from the first author's master's thesis, who wishes to gratefully acknowledge the support and guidance of Ann Fuehrer, Richard Sherman, and Stephen Hinkle in the preparation of this article, the assistance of Andrew Avellano and Jami Pennington, and the anonymous reviewers for their comments on this article.     

Amnesia for random shapes following unilateral and bilateral electronvulsive shock therapy.

Three 16-point shapes were shown to 15 patients before undergoing either unilateral or bilateral electroconvulsive therapy. They were then tested for recognition following therapy. The same subjects were similarly tested for recognition memory with no intervening shock. Analysis of variance indicated no significant differential effects of the two methods of electroshock application.     

The lateralized effects of concurrent cognitive and motor performance

Subjects were required to simultaneously tap two button switches, at two different distances apart, while at the same time performing a running memory span (RMS) task of either words or faces. Performance on the button-pressing task was assessed in terms of both speed and consistency. When the switches were close together, both of these measures showed leftand right-hand performance to be selectively disrupted by concurrent performance of faces and words memory tasks, respectively. With the switches further apart, selective disruption of the contralateral hand occurred only with thespeed index. Using the consistency index, however, bilateral disruption was observed with both types of RMS tasks. Error and d’ performance on the words and faces RMS tasks was only disrupted by contralateral manual activity. Some implications of these results for neuropsychological models of brain lateralization of function are discussed.     

The function of academic and non-academic criteria in employers' selection strategies

The different ways in which employers use educational qualifications and non-academic criteria in their recruitment and selection of young people are explored. Five different types of selection strategy are identified, each of which is characterised by a different balance between the use of academic and non-academic criteria. After a consideration of the functions that educational qualifications perform in the different strategies, the nonacademic criteria are examined in more detail. The paper concludes with an examination of the implications of these findings for careers guidance.
