A Mind of Her Own: Effects of Need for Closure and Gender on Reactions to Nonconformity

Research on opinion deviance suggests thatconformity and agreement with the established majorityis generally valued in groups. The present studyexamines how motivations for cognitive closure mayinfluence reactions to conforming and deviating membersbased on accessible gender role expectations. Caucasianmales and females participated in a group discussionwith confederates who either conformed or deviated from the majority opinion. Results showed thatgroup members motivated to reach cognitive closurenegatively evaluated female opinion deviants relative toconformists. However, contrary to previous research findings, they did not derogate male deviants.Motivation to avoid closure led to different evaluativepatterns by male and female evaluators. In addition toimportantly modifying results obtained by Kruglanski and Webster (1991) regarding closure motivationand conformity versus deviance, the current results arealso informative regarding gender role expectations andintra-group interactions. Limitations and implications of these results are alsodiscussed.     

Accepting and exempting the unexpected: 30-month-olds'' generalization of event knowledge

In 2 experiments, we used elicited imitation to test the effects of the amount and type of change to a previously experienced event on 2.5-year-olds' generalization of event knowledge. In Experiment 1, children were shown and then enacted event sequences. At two subsequent visits the props used to enact some of the sequences were completely or partially replaced by functionally equivalent props. Children used the new props to enact the events, thereby demonstrating spontaneous generalization. Nevertheless, as in previous research (Bauer & Fivush, 1992), there were decrements in performance associated with the prop-change manipulation. In Experiment 2, we examined in more detail the determinants of disruption to generalization. Results indicated that an interaction of the location and amount of change within pairs of actions joined by enabling relations (i.e., change to both members of a pair of actions occurring early in the event sequence) negatively affected generalization. Across locations, there was a greater negative effect on generalization when change was made to an antecedent rather than a consequent member of an enabling pair. We suggest that influences on the accommodation of change within events can be understood by considering the organizational role played by the elements subject to change.     

Olfaction in Persons with Alzheimer's Disease

The need for low cost, noninvasive procedures for aiding in the diagnosis and understanding of Alzheimer's Disease (AD) has led to theories and procedures examining the role of olfactory disorders because of the finding that the brains of AD patients invariably exhibit neuropathology hi the hippocampus and entorhinal cortex. This loss correlates with the increase in the number of plaques and tangles and with the severity of dementia. Considered together, these findings suggest that brain structures closely related to the olfactory system demonstrate significant histopathology in AD. A comprehensive review of the literature pertaining to olfaction in persons with AD revealed that the olfactory identification ability of patients with memory disorders is impaired relative to controls. Consistency is lacking, however, when olfactory detection thresholds are investigated. Also, there is inconsistency in regards to severity of illness and olfactory function. In addition to differentiating AD patients from normals, the olfactory paradigm has shown some limited usefulness in differentiating AD patients from some other demented patients.     

Predicting environmental learning from spatial abilities: An indirect route

Relationships among spatial abilities, as assessed by a battery of psychometric tests and experimental tasks, and environmental learning, as assessed by a series of macrospatial tasks, were examined in two studies using confirmatory factor analysis with directional paths. The initial study indicated the utility of a five-factor model, one (general spatial ability) derived from psychometric tests, two (spatial-sequential memory and spatial perspective-taking latency) from experimental tasks, and two (topological knowledge and Euclidean direction knowledge) from measures of environmental learning. The best fitting path model further indicated that the spatial-sequential memory factor mediated the relationship between general spatial ability and topological knowledge, and that perspective-taking latency mediated the relationship between general spatial ability and Euclidean direction knowledge. The second study confirmed the five-factor path model using a different participant sample and environmental setting. The only failure to replicate involved the path between perspective-taking latency in the lab and Euclidean direction knowledge in the environment. Results indicate that the relationship between basic spatial abilities and environmental learning is significantly mediated by cognitive processes that can be assessed using laboratory tasks.     

Group decision making in the planning team process: Myth or reality?

Based upon theories from organizational psychology, this study assessed the relationships among school staff role, participation, and satisfaction during planning Team meetings which decide special education placements and programming. A strong positive relationship was found between staff role and participation. Regular education teachers were lowest in participation and satisfaction whereas school psychologists were ranked the highest on both variables. Other staff roles did not necessarily show a one-to-one relationship between participation and satisfaction levels, yet within roles, the level of satisfaction increased with higher levels of participation. These findings were discussed in the context of interdisciplinary decision making and implementation of the placement team decision.     

THE ROLE OF RESPONSE DELAY IN IMPROVING THE DISCRIMINATION PERFORMANCE OF AUTISTIC CHILDREN

This study investigated the influence of a response delay requirement on the discrimination performance of autistic children. In the context of a multiple baseline design with subsequent repeated reversals, two conditions were compared: a no-response-delay condition, where the child was allowed to make the target response immediately after presentation of the discriminative stimulus versus a response-delay condition, where the target response was permitted three seconds following the discriminative stimulus when the therapist would signal the child to respond. The results showed that the response-delay condition produced higher levels of correct responding than the no-response-delay condition. In addition, teachers in the research setting rated the response-delay procedure to be a practical and effective teaching technique that could be implemented in a classroom setting. The results were discussed in relation to the literature on impulsivity, and were interpreted as indicating that the response-delay procedure provides a valuable technique for teaching autistic children.     

TEACHING MENDING SKILLS TO MENTALLY RETARDED ADOLESCENTS

This experiment presents a model for analyzing community living skills and teaching them to mentally retarded adolescents. A task analysis of three mending skills was developed and validated, aided by consultation with persons having expertise in home economics and mental retardation. The task analysis was modified to compensate for the constraints imposed by the trainees' disabilities. Five moderately retarded youths received training on sewing hems, buttons, and seams. Sewing skills were acquired rapidly and maintained. The behavior generalized from trained to untrained tasks on their common components for all subjects. A multiple baseline across participants combined with a multiple baseline across responses demonstrated the combined effectiveness of an objectively validated, detailed task analysis; graduated sequence of prompts; and response consequences in training and maintaining community living skills with mentally retarded adolescents.     

Stutterer''s scaled attitudes and their prognostic significance in therapy

Thirty individuals who manifested stuttering behavior participated in an intensive therapy program. Measures of pretherapy attitudes on the Attitude and Behavioral Observation Scale, which consists of self-evaluations of attitudes on a scale of five equal-appearing intervals and also two questionnaires, the Iowa Scale of Attitude Toward Stuttering and the Stutterer's Self-Ratings of Reactions to Speech Situations were utilized. These three scales were found to be significantly correlated. A difference score from the Motor Performance Scale, a speech proficiency scale of one to five was completed at pre- and posttherapy, as a measure of the client's success from therapy. Generally, pretherapy attitudes did not correlate significantly with success from therapy.
