The effects of impairments on employment and wages: estimates from the 1984 and 1990 SIPP

Unlike the minority groups covered by civil rights laws in the past, the disabled population is a heterogeneous group. Because of differences in the nature and onset of health conditions, it is important to study the labor market experiences of different impairment groups separately, rather than treating "disabled workers" as a single group. This article uses data from the 1984 and the 1990 panels of the Survey of Income and Program Participation to analyze trends in the employment and wages of six impairment groups in the years immediately preceding the ADA. The results confirm the diversity of labor market experiences within the disabled population and suggest that policies designed to improve labor market outcomes for workers with disabilities in response to the ADA should be targeted to the different needs of different impairment groups.     

Attention and memory for threat in panic disorder

Recently, information processing paradigms have been utilized to explore the role of attentional and memory processes in the maintenance of clinical anxiety disorders. The present study extended these data using a dual-task paradigm to assess attentional vigilance and a cued recognition task to evaluate short-term memory effects in Panic Disorder (PD). Twenty PD patients and 20 normal controls completed a computerized task wherein they read aloud one of a pair of rapidly presented words (primary task) while simultaneously attempting to detect a small probe that appeared adjacent to one of the words (secondary task). Eighty stimulus words were chosen to represent four categories: physical panic-related threat, social threat, positive-emotional, and neutral. Reaction time and accuracy in detecting the probe were assessed, as well as psychophysiological responding (heart rate, skin conductance, EMG). Following task completion, a cued recognition task was administered to examine short-term memory of task stimuli. Results indicated that PD patients exhibited slower reaction times relative to normal controls during presentation of physical panic-related threat and positive-emotional stimuli. A similar trend emerged for social threat stimuli, although the PD and control samples responded similarly to neutral stimuli. No group differences were found on the cued recognition measure or psychophysiological responding during task performance. The data are discussed in terms of possible implications for cognitive models of PD.     

Clarifying the role of shape in children's taxonomic assumption.

When asked to find a new referent of a novel label children tend to ignore thematic relations (e.g., the relation between a spider and its web) and focus instead on taxonomic relations (e.g., the relation between a spider and a snake). The precise nature of children's taxonomic assumption has not been clear, however. One possibility is that the taxonomic assumption reduces to a "similar-shape rule": perhaps children tend to select objects of the same taxonomic kind when asked to extend new labels simply because these objects are more similar in shape than objects which are only thematically related. Sixty children between 3 and 5 years of age participated in three studies which examined children's attention to thematic relations, similarity of shape, and taxonomic relations when extending novel object labels. The findings indicated that shape has some primacy in children's expectations about object label reference, yet when shape is not available as a guide, children also take taxonomic kind into consideration when searching for new referents of novel labels. Thus children make use of a relatively rich and somewhat varied set of expectations to guide their inferences about object label reference.     

Behavioral consequences of job-related stress among resident physicians: the mediating role of psychological strain

This study examined the correlations among stressors, psychological strain, and behavioral reactions in a national sample of 1785 resident physicians, 27 to 33 years old. Consistent with previous studies of resident physicians, analysis showed that those experiencing high job-related stressors experienced high psychological strain in both their personal and professional lives. Stressors were also correlated with behavioral reactions. Hierarchical regression suggested that psychological strain mediated the relations between two of the stressors and behavioral reactions to some extent. This was consistent with recent research suggesting that psychological reactions may mediate the relations between stressors and outcomes. Further research on both medical residency and the stressing process was suggested.     

Social Comparison,the Threat of AIDS,and Adolescent Condom Use1

This study tested hypotheses from social comparison theory about adolescent condom use. Questionnaires were administered to 457 twelfth-grade students (284 sexually active). Three different operationalizations of social comparison were used—comparative ratings, affiliative preferences, and derogation; each produced different results. Low condom users who felt threatened by AIDS made more downward comparative ratings regarding condom use than did unthreatened low users. In contrast, low users preferred upward affiliations with high users. Adolescents with higher self-esteem derogated adolescents with AIDS less as threat increased. Adolescents with lower self-esteem who made downward comparative ratings were more satisfied with their own past condom use. Satisfied low condom users were less likely to intend condom use in the future. The results provide evidence that downward comparison may act indirectly to deter behavioral change.     

Further evidence of associations of type a personality scores and driving-related attitudes and behaviors

The present study examined the effects of Type A personality on specific self-reported driving attitudes and behaviors when operating a motor vehicle. 102 undergraduate students completed the student version of the Jenkins Activity Survey (Form T) and several questionnaires asking participants about their driving history, driving attitudes, and driving behaviors. When the full range of Type A scores were examined, Type A personality was significantly related to more traffic accidents, greater frequency of breaking traffic laws, higher impatience when driving, more displays of aggression on the road, and engaging in more risky driving behaviors (rs<.17). When extreme Type A and Type B scores were compared, Type A drivers reported being involved in significantly more motor vehicle accidents and reported displaying more aggression on the road. Further research should examine actual behavioral data using more diverse samples to validate the results.
