Adjustment problems in the family and school contexts, attitude towards authority, and violent behavior at school in adolescence

This study analyzed the role of different but interrelated variables in the family and school contexts in relation to problems of violent behavior at school during adolescence. Participants were 1,068 students aged 11 to 16 (47% male) drawn from secondary schools in the Valencian Community (Spain). Statistical analyses were carried out using structural equation modeling. The model accounted for 32% of the variance in school violence. Results showed a direct association between quality of communication with father and teacher's expectations of the student with the adolescent's involvement in violent behavior at school. Moreover, findings showed indirect paths by which adolescents' self-concept (family and school domains), acceptance by peers, and attitude toward authority, seemed to be influenced by the quality of interactions with parent and teachers, and also were closely associated with violent behavior at school. Findings are discussed in relation to previous research on adolescent psychosocial adjustment and behavioral problems at school.     

Attention during visual secondary tasks in driving: Adaptation to the demands of the driving task

Visual attention in driving with visual secondary task is compared for two visual secondary tasks. N = 40 subjects completed a 1 h test drive in a motion-base driving simulator. During the drive, participants either solved an externally paced, highly demanding visual task or a self paced menu system task. The secondary tasks were offered in defined critical and non-critical driving situations. Eye movement behavior was analyzed and compared for both tasks. Before starting the secondary tasks, eye movement behavior shows a smaller standard deviation of gaze as well as longer fixation durations for both tasks. The comparison between the two tasks indicates that drivers use the possibilities the self paced task offers: during the secondary task, they monitor the driving scene with longer fixations and show a greater standard deviation of gaze position. Furthermore, independently of the type of secondary task, drivers adapt their eye movement behavior to the demands of the situation. In critical driving situations they direct a larger proportion of glance time to the driving task. Last, the relation between glance behavior and collisions is analyzed. Results indicate that collisions go together with an inadequate distribution of attention during distraction. The results are interpreted regarding the attentional processes involved in driving with visual secondary tasks. Based on the similarities and differences between the two secondary tasks, a cognitive approach is developed which assumes that the control of attention during distraction is based on a mental situational model of the driving situation.     

Prevalence of smokeless tobacco consumption at a southwestern university

265 students attending a southwestern university were surveyed about their use of smokeless tobacco products. 27% of 84 male respondents indicated they consumed smokeless tobacco. The women did not report routine use of smokeless tobacco.     

Inviting witnesses to speculate: effects of age and interaction on children's recall

Inviting speculation has been found to increase children's false recall. In this study, kindergartners and third graders saw a clown perform actions alone or in interaction with a child. Two weeks later, the speculation group recalled all actions and was asked to speculate on half the actions. The control group recalled all actions without speculating. Four weeks after the show, all children recalled all actions again. The speculation group gave more false answers to the speculated items than the control group. Surprisingly, older children tended to report as many if not more false responses than younger children, regardless of speculation. In the speculation group, there were fewer false answers for interactions than actions, but false answers did not differ across observation types in the control group. Finally, speculation did not affect free and cued recall differentially.
