Content Effects on Decision Making

How does the domain or subject matter of a decision problem affect the outcome of the decision? Although decision-making research typically dismisses content as merely a cover story, the present research shows that it plays a fundamental role in the decision process by influencing the information processing that underlies it. An experiment is reported in which the same basic decision problem was presented in several content domains (legal traffic tickets, academic course grades, stock investments, and casino gambling). The changes in content led to changes in both strategies and mental representations, which in turn led to changes in decision outcomes, even though measures of the subjective utilities of the options remained unchanged.     

A neural network approach to identifying adolescent adjustment.

This study examined the relationship between the quality of adjustment in adolescents and a set of psychiatric diagnoses, personality traits, parental bonding, and social support variables. One hundred fifty adolescents were administered the Millon Adolescent Personality Inventory, the Parental Bonding Questionnaire, the Social Support Questionnaire, and the Diagnostic Interview for Children and Adolescents. A neural network approach was then utilized, and it was found that several of the variables (e.g., Major Depressive Disorder, Conduct Disorder, and Societal Conformity) had a significant role in classifying adolescents into three groups: maladjusted, nominally adjusted, and well-adjusted.     

Lateralized audiogenic seizure: motor asymmetries exhibited and the effects of interrupted stimulation

Sensitized SJL/J mice were monaurally tested for susceptibility to sound-induced seizure. The acoustic stimulation was interrupted for 15 s at various points during the biphasic pattern of running which these mice characteristically exhibit before seizing. Asymmetries of run directions and side of fall were noted. In addition, a dramatic reduction in seizure incidence was found when the interruption either extended into the period when the later burst of running would have occurred or began during this running burst. Finally, the results indicate that the latencies to the later running burst and the subsequent seizure are determined at or about the time of the onset of the first burst of running.     

Increasing volunteering at a residential facility: An experimental evaluation of a volunteer assistance program

A helpful component for comprehensive residential services for developmentally disabled persons is volunteer assistance. This investigation involved the evaluation of a program developed to increase the amount of volunteer assistance provided to a public residential facility. The program consisted of three types of related procedures: systematic volunteer recruitment steps, specific volunteer activities at the facility, and consequence/recognition for the volunteer assistance. The program was successively implemented to involve students as volunteers from two local universities, and resulted in an increase in new students volunteering from both universities. Additionally, the frequency with which the students volunteered at the residential facility increased substantially from both universities relative to control periods during which the volunteer program was not in effect. Results are discussed in terms of the benefits of volunteers and continued research to increase involvement of other prospective groups of volunteers.     

Construct similarity, self-meaningfulness, and interpersonal attraction

Self-meaningfulness, a concept arising from personal construct theory research, has been defined in terms of the importance of the self in the personal construct system Forty-two undergraduate volunteers completed Repertory Grid ratings of the self and 15 individuals (five liked, five disliked, and five toward whom the subject was neutral) It was found that high self-meaningfulness individuals' ratings of attraction were more strongly associated with the perception of similarity than were the ratings of low self-meaningfulness subjects High self-meaningfulness subjects saw liked individuals as significantly more similar to the self than did low self-meaningfulness subjects In addition, liked, neutral, and disliked figures were seen as significantly different from one another on the similarity to self-measure for high self-meaningfulness subjects Only disliked figures were judged as more distant from the self for low self-meaningfulness subjects These findings were discussed in terms of the importance of investigating individual differences in similarity-attraction     

The development of antisocial behaviour patterns in childhood and adolescence

A developmental model of antisocial behaviour is presented in this paper. Arguments and evidence are presented for the position that although many factors such as parent criminality, social and economic disadvantage, child temperament, and marital discord systematically affect the development of antisocial child behaviour, their influence is mediated by the extent to which they disrupt day-to-day parenting practices. Particularly, it is argued that irritable, ineffective discipline and poor parental monitoring are the most proximal determinants of the early development and maintenance of antisocial behaviour. The implications of this model for prevention and intervention in child conduct problems are discussed, using examples of promising clinical work that focuses on direct parent training.
