Response rate and sensitivity to the molar feedback function relating response and reinforcement rate on VI+ schedules of reinforcement

In 5 experiments, the author examined rats' sensitivity to the molar feedback function relating response rate to reinforcement rate on schedules of reinforcement. These studies demonstrated that, at lower rates of responding, rats' performance on variable ratio (VR), variable interval (VI), and variable interval with linear feedback loop (VI+) schedules was determined largely by reinforcement of interresponse times; response rates were faster on VR than on both VI and VI+ schedules. In contrast, when procedures were adopted to maintain high rates of response, rats showed sensitivity to the molar characteristics of the schedules; they responded as fast on a VI+ schedule as on a VR schedule and faster on both of these schedules than on a yoked VI schedule. When the variance of response rate was manipulated, this factor was noted as an important element in determining sensitivity to the molar characteristics of the schedule.     

The parental attitude research instrument: An approach to use of attitude questionnaires

Parental attitude questionnaires such as the Parental Attitude Research Instrument (PARI) are still in use despite their inherent difficulties. In light of the need to test theoretical models by measuring a range of parental characteristics, the properties of the PARI were re-examined and, on the basis of a factor analysis of the 23 subtests of the PARI, a shortened version was constructed. A measure of maternal Authoritarian Control, which was found to be associated with measures of maternal mental ability, personality, level of education, reading age, number of adverse family conditions and child-rearing practices, has proved useful for other projects related to this ongoing study. It is recommended that such instruments be used only in conjunction with other measures which examine the family environment, for example in an index of child-rearing practices.

The structure and correlates of self-reported symptoms in 11-year-old children

Self-reports of DSM-III symptomatology were obtained from 792 11-year-old children using the Diagnostic Interview Schedule for Children (DISC). We report results concerning 13 subscales derived from the DISC. Factor-analysis of the subscales suggested a broad distinction between externalizing and internalizing disorder for boys' self-report. For girls, two separate internalizing factors representing anxiety and depression emerged. We also found sex differences in correlates of self-reported disorder. Finally, we examined agreement between child and parent and teacher reports. Overall, agreement was relatively low, although somewhat higher for child-parent than for child-teacher.The Dunedin Multidisciplinary Health and Development Research Unit is supported by the Medical Research Council of New Zealand and the Departments of Education and Health, and involves several departments of the University of Otago. Much of the data are gathered by voluntary workers from the Dunedin community. The authors are indebted to the many people whose contributions make this ongoing study possible.     

Cognitive problem-solving and life event correlates of depressive symptoms in children

This study examined the relationship between a number of cognitive problem-solving and life event variables and depressive symptoms in a sample of non-referred grade school children. The results indicated that higher levels of depressive symptoms were associated with an external locus of control, increased levels of objective and subjective life stress, and lower performance levels on an impersonal problem-solving task. Level of depressive symptoms was also found to be inversely related to socioeconomic status as measured by father's occupation. Contrary to prediction, no consistent relationship was found between depression and interpersonal problem-solving ability.This research is based on the first author's master's thesis submitted under the supervision of the second author to the Department of Psychology, University of Missouri-Columbia.     

Asthma-specific cognitions,self-focused attention,and fear of negative evaluation in adolescents and young adults diagnosed with childhood-onset asthma

The present study examined the impact of asthma-specific thought intrusion (TI) and thought suppression (TS) on two cognitive-affective variables (self-focused attention and fear of negative evaluation) among adolescents and young adults (AYAs) diagnosed with childhood-onset asthma. Participants were 290 AYAs who completed assessment questionnaires and participated in a written exercise electronically. Asthma-TI and TS were reported by participants following participation in a writing assignment. Asthma-TI was associated with increased private, public, and social anxiety self-focused attention, and greater fear of negative evaluation. Interestingly, asthma-TS was not associated with these same outcome variables. Findings suggest illness-specific cognitions are associated with cognitive-affective variables and it may be important to assess for illness-specific intrusive thoughts following asthma-focused medical appointments. Additionally, findings suggest the importance of assessing asthma-TI and TS separately in order to better understand thoughts about health and psychological functioning.     

Personal and Professional Development for Judges: The Institute for Faculty Excellence

This interview study describes the role that participation in the Institute for Faculty Excellence in Judicial Education (IFEJE) played in the personal and professional development of four judges. Judicial education is a relatively new field of adult and continuing professional education. There is limited literature devoted to this area of study outside of the arena of substantive legal or judging topics. Interviews served as the primary data source for this study along with program evaluations, photographs, and e-mail correspondence from Institute participants. The findings revealed that the combined safe environment, challenges, and support participants experienced at the Institute and learning about adult learning helped them: feel less isolated in their work; stretch their normal work boundaries resulting in the completion of projects for which they had great passion; and benefited them as judges, supervisors, teachers, and in other social relationships.
