SOCIAL CLASS PERCEPTION AND SOCIAL STATUS AMONG SWEDISH YOUTH

Social class perception (identification) was studied as a function of ‘objective’ status (socioeconomic level) and class (occupational class) using a sample of Swedish high school students. Confirming the two minor hypotheses, the results disclosed that class perception was affected by both the ‘objective’ class and status of the subject: the manual occupational class, and those with low socioeconomic status, had in general a higher proportion of working-class identification than the nonmanual class, and those with low socioeconomic status, respectively. However, the major hypothesis, an interaction hypothesis stating that manuals are not affected by status in their class perceptions, was not confirmed. The results are discussed in the context of social psychological theory and earlier empirical research.     

Perceived family environment as a moderator of young adolescents' life stress adjustment

A longitudinal design was employed to test the main and stress-moderating effects of young adolescents' perceived family environment (Family Environment Scales; FES; Moos & Moos, 1981) on their depression, anxiety, and self-esteem. This study was part of a larger longitudinal project (L. Cohen, Burt, & Bjorck, 1987) that demonstrated the significant cross-sectional effects of the young adolescents' controllable and uncontrollable negative events, and the significant longitudinal effects of the former. The present cross-sectional analyses demonstrated the hypothesized main effects of the FES scores; families perceived as cohesive, organized, and expressive were related to positive psychological functioning, whereas families perceived as conflict-ridden and controlling were related to negative functioning. However, in general these effects were nonsignificant in the longitudinal analyses. Although there were a number of significant Negative Events x FES interactions, in no instance did the pattern support the hypothesized stress-buffering role of positive family climate.     

The discrimination of human odour by the dog

In reply to a suggestion made by Galton in 1875, the ability of dogs to discriminate between the odour of human twins was investigated. In a matching-to-sample simultaneous discrimination task, dogs were tested on their ability to discriminate odours from twins differing only in genetic relatedness or only in environmental factors, particularly diet, or from twins identical in both genetic relatedness and environmental factors. Dogs could discriminate between the odours from twins who differed only in environmental factors and between the odours of twins who differed only in genetic relatedness. However, they were unable to discriminate between odours produced by infant twins identical in both genetic relatedness and environmental factors. Thus twins may be discriminated by dogs as long as they differ in genetic relatedness or environmental factors. The possible source of discriminable odours is discussed and how the effects of genes and environment are mediated considered.
