Video primacy—A further look

This paper reviews the literature on the complex question of the relative importance of the verbal, visual and vocal channels in various types of judgments. It is noted that a wide variety of methodologies are used in such research with studies differing in terms of the type of stimuli used (varying on the dimension of stylised to naturally occurring), the task required of the subjects (particularly varying on the cognitive-affective dimension) and the method used to assess the relative importance of the channels. An attempt is made to assess the important variables which affect the way the various channels are used by decoders, including whether deception is involved or expected, whether the message is discrepant, the particular judgment being made and the dimension on which the stimulus varies, the sex of the encoder and the decoder and the relationship between them, and the age of the decoder. The possibility of other related variables also acting as moderators is discussed.     

THE EFFECTIVENESS OF FAMILY THERAPY IN THE TREATMENT OF ADOLESCENTS WITH CONDUCT DISORDERS AND DELINQUENCY

A literature review was conducted on recent studies using family therapy approaches to the treatment of conduct disorders in adolescents. Results from studies conducted since the Shadish et al. (1993) meta-analysis on the effects of family and marital therapies are included. Barriers to effective treatment are identified, costs of care are discussed, and a variety of systems of care in which family interventions are embedded are reviewed.

Behavioural techniques for enhancing alertness and performance in shift work

This paper reviews behavioural and cognitive methods for increasing alertness, enhancing performance, and decreasing long-term negative consequences due to shift work. Methods having the most potential for effective intervention include the short-term alerting effects of the optimal timing of work breaks, social activity during breaks, and sensory stimulation. Stress coping techniques and sleep hygiene information for workers and their families have the most potential for addressing long-tcrm effects of shift work. Recommendations for areas requiring further investigation include the altering effects of bright light, fresh air, and cold water; performance enhanccmcnt through psychophysiological self-regulation and imagery; and the impact on performance of second jobs and family responsibilities.     

The “hurried child”: The myth of lost childhood in contemporary American society

The hurried child writers argue that childhood has changed fundamentally for the worse in contemporary American society. The authors assert that today's youth are too adultlike: they behave like adults and are treated as adults by parents, schools, the workplace, the media, and society in general. While offering some perceptive insights, the thesis poses numerous methodological, substantive, and empirical problems. These include (1) a limited historical perspective on the changing nature of American childhood, (2) a failure to identify exactly who the hurried children are, and (3) the use of a deterministic model and negative bias in their work. Our analysis indicates no large-scale destruction of childhood and adolescence hypothesized by the hurried child writers. For the vast majority of contemporary American children, the hurried child is more myth than reality.     

Rethinking Occupational Integration

This paper uses US Census data from 1970 to 1990 to focus on “integrated” occupations—those in which men and women are approximately equally represented. We focus on the extensive variability that exists across these nominally integrated occupations, specifically their social demography and the paths by which they reach compositional sex equity. We also examine the link between occupational integration and race/sex succession, and explore the earnings consequences of working in mixed occupations. Our findings suggest that integration means quite different things at different levels of the occupational hierarchy and for the women and men integrating sex-atypical occupations. This is a revised version of a paper presented at the Annual Meetings of the American Sociological Association, Anaheim, CA, August 2001.     

Commuters' eye contact with strangers in city and suburban train stations: Evidence of short-term adaptation to interpersonal overload in the city

In the present study experimenters attempted to make eye contact with commuters as they approached an express train linking city and suburb and, 20 minutes later, as commuters left the same train. During both the morning rush from suburb to city and the evening rush from city to suburb, commuters were less willing to meet an experimenter's eye at the city train station than at the suburban station. These results support the hypothesis that reduced eye contact with strangers in the city is a short-term adaptation to interpersonal overload in the city. Most generally the results indicate a convergence of laboratory and field data toward the conclusion that crowding effects on behavior are best understood as adaptation to interpersonal overload.
