On the handling of heavy bias in a self-paced task

Following an earlier observation that systematic variations in performance on a task with heavy frequency imbalance was correlated with fluctuations in the amount of bias in the input programme, an experiment was carried out to establish the roles of long and short term sampling. Two groups of subjects were trained on a self-paced, five-choice task. One group's input had an average of 68 per cent. bias on one source, the other had 44 per cent. on the same source. Analysis of data was carried out on three levels of local bias for each condition, one level being identical for both conditions. It was found that responses to the biased stimuli were determined by the average bias in each input sequence and not by moment to moment variations in that bias. The effect observed originally can therefore be accounted for in terms of a relatively simple additive model which includes the “repetition effect” first described by Bertelson.     

Interaction of asthmatics and their spouses: A preliminary study of individual differences

Some asthmatics show evidence of airways reactivity triggered by strong emotions. Six case studies of married patients with severe asthma are reported. The videotaped interactions of the asthmatic and his/her spouse were coded for affect and behavior. Repeated measures of pulmonary function and affective state were recorded before and after two interaction tasks. Over the course of the experimental period, two patients' pulmonary function improved and four patients' deteriorated. In general, decreased pulmonary function was associated with more self-rated hostility and depression. The results are discussed in terms of their implications for the intra- and interpersonal factors that are important in asthma management.     

Gender and computers. II. The interactive effects of knowledge and constancy on gender-stereotyped attitudes

A number of studies have failed to find that gender constancy (understanding that one's gender is permanent) predicts gender-typed attitudes and behavior. This study (run with a predominantly white sample) tests the hypothesis that gender constant children are motivated to master gender roles, but that how well they do so depends on their knowledge of gender stereotypes. We predicted that attitudes toward computer use (a stereotypically male activity) would be less positive only for 5–9-year-old gender constant girls who also had rich gender stereotypes. Predictions were confirmed, especially for girls whose constancy had recently increased. These data thus suggest that the clearest picture of gender role development emerges when both the unique and interactive effects of gender constancy and gender schema development are assessed. They also indicate that gender differences in computer attitudes can develop through self-socialization processes.This research was supported in part by research Grant No. R37 MH37215 and Research Scientist Development Award No. 00484 from the National Institute of Mental Health to the third author.

Testing Damasio's somatic marker hypothesis with psychopathic individuals: risk takers or risk averse?

Damasio and colleagues (A. R. Damasio, 1994; A. R. Damasio, D. Tranel, & H. Damasio, 1990) have theorized about a possible relationship between somatic markers and the behavior of psychopathic individuals (Ps), but, to date, there are no published data regarding the proposed relationship. The authors assessed 86 Caucasian and 71 African American male offenders using R. D. Hare's (1991) Psychopathy Checklist--Revised and used a modified version of Bechara and colleagues' (A. Bechara, A. R. Damasio, H. Damasio, & S. W. Anderson, 1994; A. Bechara, H. Damasio, D. Tranel, & A. R. Damasio, 1997) gambling task to test the hypothesis that Ps would, consistent with the somatic marker hypothesis, fail to become risk averse. Results indicated that level of anxiety, but not psychopathy, was predictive of response choices. Several limitations and implications of the study are noted.     

Sex Differences in the Relationship of Anger and Depression: An Empirical Study

A comparison of mean scores on the Beck Depression Inventory and State-Trait Anger Expression Inventory scales revealed that women scored significantly higher than men on depression, whereas there were no significant differences on any of the 6 anger scales. Separate multiple regression analyses revealed that there were statistically significant relationships between the linear combination of anger scales and depression for both groups. A comparison of zero-order correlations of depression with the anger scales revealed that Anger-In correlated significantly more highly with depression among women than men. Finally Anger-In correlated significantly with 4 of the 5 other anger scales for women, but only with one for men.
