A context-specific detrimental effect of UCS preexposure on place conditioning with morphine

The effect of morphine preexposure on place conditioning with morphine was investigated. In the first experiment, five injections of 10 mg/kg morphine were administered to rats prior to place conditioning or taste-aversion training with morphine. Although this number of preexposures retarded taste-aversion learning, there was no effect on place conditioning. In subsequent experiments we investigated the role of context blocking in UCS preexposure in place conditioning. In one experiment, preexposure to five morphine injections prior to place conditioning resulted in a reduced place preference, compared with preexposure and place conditioning in different contexts. However, the overall detrimental effect of morphine preexposure was questionable, because the rats that were preexposed were only marginally different from those that were not preexposed. In a final experiment we examined the effect of a context change from preexposure to place conditioning with 15 preexposures and demonstrated a detrimental effect of preexposure on place conditioning that was context specific. These results support a role of classical conditioning in place-preference conditioning with morphine.     

Approaches to studying in deaf and hearing students in higher education

We conducted a survey to compare the responses of 149 deaf students and 121 hearing students taking the same courses to a shortened and adapted version of the Approaches to Studying Inventory. In general, the impact of deafness on approaches to studying was relatively slight, and deaf students appeared to be at least as capable as hearing students of engaging with the underlying meaning of the materials to be learned. We used factor analysis to identify eight scales, and differences between the two groups were statistically significant on four of these scales. Discriminant analysis indicated that deaf students found it more difficult to relate ideas on different topics and that this was more marked in those who preferred to communicate using sign. However, deaf students were more likely than hearing students to adopt a critical approach and to analyze the internal structure of the topics studied.     

Predicting early school success with developmental and social skills screeners

The purpose of this study was to identify developmental, social skill, and problem behavior sub-domains that best predict academic achievement and grade promotion or retention in the early school years. Subjects were 184 children tested at the end of kindergarten using the Early Prevention of School Failure screening package and the Social Skills Rating Scale, and a year later using the Stanford Achievement Test. Information on promotion or retention was gathered in late spring for the two school years. Four kindergarten screening areas figured prominently in predicting first grade academic success: receptive language, visual memory, cooperation, and self-control. In addition, social skill subscales played significant roles in predicting promotion and retention. The findings suggest that assessment of social skills should be included in kindergarten screening packages with the possibility of targeting deficits for early intervention. © 1997 John Wiley & Sons, Inc.     

Evidence-Based Methods for Children and Youth with Autism Spectrum Disorders: Stakeholder Issues and Perspectives

Despite variable interpretations of the meaning and nature of specific effective practice methods and research-supported strategies, such approaches are generally considered essential for children and youth with autism spectrum disorders (ASDs). Indeed, there is general consensus that only by qualified professionals using effective methods in an approved fashion will optimal student outcomes be achieved. Related to this need, this article presents perspectives of stakeholders connected to use of effective practices with children and youth diagnosed with ASD. A parent, educational practitioner, and program administrator each share their unique perspectives on the subject of effective practice methods for learners with ASD.     

Research Supervision: An Important Site of Teaching

Supervision of students engaged in research projects and theses is an important site of teaching. Schon's (1987) well-known framework–educating for reflective practice–proves aptly suited for this teaching forum, offering insights for research supervision at multiple university levels. Conceptually, a research and writing studio where a practicum takes place is substituted for Schon's illustrative architectural design studio. The framework is mined for its fine-grained analysis of student-coach interaction and its emphasis on bringing self-reflection, a practice consistent with social work ideals, to three levels: research and writing, the student-coach dialogue and the relationship in which it is embedded.
