Polarizing effects of intergroup comparison

Compared the effects of intergroup and within-group comparison on attitudes differentiating two well-defined student groups. Social work students (n = 48) expressed attitudes either before or after estimating ingroup or outgroup (commerce students) norms. Subjects adopted more extreme attitudes following outgroup comparison, but were unaffected by comparison within the group.     

Achievement motivation in college women revisited: Implications for women,men, and the gathering of coconuts

An attempt was made to replicate the findings of French and Lesser (1964) within one university on the effects of value-appropriate arousal conditions on achievement motivation scores and motivation performance relationships in women. The findings of this study do not uphold those previously reported. There were no significant differences on either achievement motivation scores or task performance under value-appropriate versus -inappropriate arousal conditions. In the present study there were two innovations — performance criteria were extended to include academic performance, and scoring procedures were developed to give equal weight to achievement imagery in areas defined as traditionally feminine. The principle findings concern the importance of the scoring procedures. Intellectual (classic) N Ach does not relate to value orientation, task performance, or grade point average. Women's Role N Ach, however, is significantly related to task performance and to grade point average. This motivation-performance relationship exists despite differences in value orientation among women. It is suggested that when scoring procedures allow subjects, male or female, to express achievement strivings in areas of value to them, then performance may be morc sensitive to motivational variables.This article is based on research supported by Grant 1 RO1 HD-02403-01 from the National Institute of Mental Health to Lynette K.

Families-at-risk and home-based intervention: A therapist training model

Home-based family therapy programs are designed to provide intensive family intervention for at-risk children and adolescents. However, examination of the literature reveals limited publications about training therapists for this difficult task. The purpose of this paper is to describe a therapist training model based upon a family-as-context approach to crisis intervention. Specific units covered during the course include: family-as-a-system, structural family therapy, family crisis intervention, family assessment and simulation. It is concluded that the effective prevention of placement for at-risk children and adolescents requires both a home-based family treatment program and a specific therapist training model for family intervention.John J. Zarski, PhD, is a professor in the marriage and family therapy training program at the University of Akron. Carol A. Pastore is program coordinator for the T.I.E.S. program in Canton, OH. A. Lynette Way and Richard N. Shepler are home-based therapists with T.I.E.S.

Within-session meal-size effects on induced drinking.

As a control for the effects of session duration and hunger on the relation between food magnitude and induced drinking, four food-deprived rats were exposed to a variable-time 50-s schedule of food delivery in which the size of each food delivery varied randomly within sessions. Food-related behavior and schedule-induced drinking per opportunity were examined as functions of meal size and postfood time. All rats showed an inverted-U-shaped relation between drinking per opportunity and meal size. This relation was caused by variation in the percentage of intervals that contained drinking and by variation in the number of drinking bouts per interval, rather than by bout duration or by the amount of drinking within those intervals that actually contained drinking. Head-in-feeder time increased linearly with meal size. Schedule-induced drinking was entrained by food delivery in 3 of 4 subjects; the entrainment was due to regulation of the starting time of each drinking bout rather than to regulation of bout duration.     

The influence of similarity between relevant and irrelevant information upon a complex identification task

This experiment sought answers to two questions: (1) Do increases in the similarity between relevant and irrelevant information present in visual stimulus patterns detrimentally influence the performance of a complex identification task, and (2) does the effect of such similarity interact with increasing amounts of irrelevant information? An analysis of the response latencies and errors indicated that identification of the relevant information in the stimulus patterns becomes significantly poorer with increasing similarity between relevant and irrelevant information and with increasing amounts of irrelevancy. The results also showed that the joint effect of similarity and irrelevancy produces a greater performance decrement than that associated with either variable alone. Practice on the task reduced the detrimental effects.     

EXPANDING THE IMPACT OF BEHAVIORAL STAFF MANAGEMENT: A LARGE-SCALE,LONG-TERM APPLICATION IN SCHOOLS SERVING SEVERELY HANDICAPPED STUDENTS

Experimental evaluations of behavioral staff management procedures usually have been limited to relatively small-scale demonstration studies. We evaluated a large-scale, long-term application of a staff management program designed to improve the functional utility of educational services for severely handicapped persons. The intervention, involving a brief in-service program followed by supervisory prompts and feedback, was implemented by three principals in four schools involving 21 classrooms. Implementation of the management procedures was consistently accompanied by increases in student involvement in functional educational tasks in each classroom. Further, the improved services continued throughout a 2-year follow-up period. Staff responses to a questionnaire indicated a high degree of staff acceptance of the management program. Results are discussed in terms of expanding the use of behavioral supervisory procedures from experimental demonstrations to actual adoption by existing human service agencies.
