Influencesicture context on object recognition

The effect of sorrounding context on the recognition of objects from briefly presented pictures was investigated. Forty-eight undergraduates saw 100 msec displays of either line drawings containing several objects embedded in context or drawings of object arrays without background context. Following each exposure they were required to select from among four objects the one that had been contained in the picture. Presentation of objects in context aided recognition only when incorrect response alternatives were inconsistent with the picture context. The results suggest that context contributes to the construction of a general characterization of the pictures which provides expectancies regarding the identity of specific objects.     

Stress and strain in blue-collar and white-collar management staff

Previous research has demonstrated the relationship of work stress to indices of job strain, as well as underscoring the importance of moderating variables. In the present study of a mining organization it was hypothesized that personnel associated with actual mining operations would demonstrate stress-strain relationships different from those associated with administrative and staff work. Measures of stress and strain were obtained from management staff of blue-collar and white-collar groups to assess the moderating influence of collar color. Results strongly support collar color as a moderator variable. In particular, the two groups differ significantly with respect to how role conflict, job security, quantitative work load, variation in work load, and utilization of skills impact various strains. The effect of job function on stress and strain and possible practical implications of these results are discussed.     

Cognitive changes associated with social skills training

Changes in locus of control and self-esteem during social skills training and at 6 month follow-up were investigated. Forty-four adolescent, male offenders were randomly assigned to a social skills training, attention-placebo, or no-treatment control procedure. The results showed that pre- to post-training increases in self-esteem were produced for both the social skills training and attention-placebo control groups, but not for the no-treatment control group. These increases did not continue during the follow-up phase; the social skills training group, which showed the greatest improvement during training, displayed a decrease in self- esteem during follow-up.The locus of control measures showed a statistically significant shift towards internality for the social skills training group during training, which was not found for the attention-placebo and no-treatment controls. During the follow-up phase, all three groups showed a statistically significant shift towards externality, suggesting a tendency for boys to view their behaviour and consequences as being under the control of chance factors or powerful others, during institutionalization. This effect was partly reversed during training for the social skills training group, but the effect was not long lasting. It seems therefore that social skills training is effective in producing an increase in self-esteem and a shift towards internal locus of control. These changes are, however, of short duration and the self-esteem shift may be the result of increased staff contact or other non-specific therapy factors.
