Parent-identified problem preschoolers: Mother-child interaction during play at intake and 1-year follow-up

Parent-referred 2- and 3-year-olds and controls, participating in a longitudinal study of hyperactivity and related behavior problems, were observed with their mothers during play at an initial assessment and a 1-year follow-up. Mothers of problem children provided more redirection initially and made more negative control statements at follow-up than mothers of controls; problem youngsters tended to play more aggressively. Sex differences were prominent. Mothers of boys, regardless of referral status, were more directive at the initial assessment; their sons were less cooperative and somewhat more aggressive in their play. Maternal involvement in play decreased over time, possibly as a response to developmental changes in children's play. Group by time interactions indicated that mothers of control children provided fewer negative control statements at follow-up relative to mothers of problem children and to their own levels at the first assessment; mothers of problem youngsters redirected their children less than they had initially. Mothers of boys were also less directive at follow-up relative to their initial levels. Situational and developmental factors are discussed briefly.     

Recreation as a reinforcer: increasing membership and decreasing disruptions in an urban recreation centre

It is presumed that recreation activities have a variety of functions for people, from tension reduction to citizenship development; however, a recreation activity's most empirically obvious function is as a reinforcer. This study demonstrates how two recurrent problems of urban recreation programs-recruitment of members and reduction of disruptive behaviors within the program-can be handled simply by contingently adjusting the amount of time the recreation activities are available. When extra time in the recreation center was provided to those youths who brought new members, dramatic increases in membership were achieved. On the other hand, when the closing time for each evening's recreation program was publicly moved forward by a few minutes for each offense, disruptive behaviors were nearly eliminated. Recreation used as a reinforcer can thus improve the basic operation of a recreation center and might similarly enhance other presumed and desired functions of recreation.     

Applied behavior analysis: New directions from the laboratory

Applied behavior analysis began when laboratory based principles were extended to humans inorder to change socially significant behavior. Recent laboratory findings may have applied relevance; however, the majority of basic researchers have not clearly communicated the practical implications of their work. The present paper samples some of the new findings and attempts to demonstrate their applied importance. Schedule-induced behavior which occurs as a by-product of contingencies of reinforcement is discussed. Possible difficulties in treatment and management of induced behaviors are considered. Next, the correlation-based law of effect and the implications of relative reinforcement are explored in terms of applied examples. Relative rate of reinforcement is then extended to the literature dealing with concurrent operants. Concurrent operant models may describe human behavior of applied importance, and several techniques for modification of problem behavior are suggested. As a final concern, the paper discusses several new paradigms. While the practical importance of these models is not clear at the moment, it may be that new practical advantages will soon arise. Thus, it is argued that basic research continues to be of theoretical and practical importance to applied behavior analysis.     

DEVELOPMENT OF A JOB ANALYSIS-BASED PROCEDURE FOR WEIGHTING AND COMBINING CONTENT RELATED TESTS INTO A SINGLE TEST BATTERY SCORE

By definition, content-related approaches to test validation do not rely on criterion data. As a consequence, regression and other statistical procedures for weighting and generating a composite score from a test battery are not applicable when a content-related validation strategy is used. This paper presents a procedure for determining the component weights for a test battery that has been developed on the basis of a content-related validity strategy. The Relative Content Contribution (RCC) weighting procedure is a logical extension of the conceptual basis underlying the rational developmental process used to demonstrate the validity of content-related tests. Results from field implementations of the procedure in the development of two promotional test batteries (fire and police) and an entry-level test battery (police) in two large metropolitan cities are presented to illustrate the procedure.     

GRIDLAT: Toward a constructivist methodology to investigate brain lateralization

Verbal conceptual processes and emotional experience (in general, as well as positive vs. negative) are phenomena that appear to have lateralized correlates. A general method is herein put forth by which researchers can investigate the lateralization of various constructive processes in the brain. The technique, called GRIDLAT, is a computerized repertory grid protocol that displays element and construct information to a single hemisphere (vis à vis visual field) at a time during grid elicitation. GRIDLAT is described in detail. Then some preliminary findings are described, and several dependent variables possible in studies employing methods such as GRIDLAT are discussed.     

Activity anorexia: An interplay between basic and applied behavior analysis

The relationship between basic research with nonhumans and applied behavior analysis is illustrated by our work on activity anorexia. When rats are fed one meal a day and allowed to run on an activity wheel, they run excessively, stop eating, and die of starvation. Convergent evidence, from several different research areas, indicates that the behavior of these animals and humans who self-starve is functionally similar. A biobehavioral theory of activity anorexia is presented that details the cultural contingencies, behavioral processes, and physiology of anorexia. Diagnostic criteria and a three-stage treatment program for activity-based anorexia are outlined. The animal model permits basic research on anorexia that for practical and ethical reasons cannot be conducted with humans. Thus, basic research can have applied importance.     

Factors Associated With Participating in a Romantic Relationship in a Work Environment1

Questionnaires were administered to graduate students employed by a large university to assess part of Pierce, Byrne, and Aguinis's (1996) model of workplace romance. Based on data from 297 respondents, results indicate that (a) females held less favorable attitudes toward romance and sexual intimacy at work than did males, (b) participating in a romantic relationship with a member of the same organization was positively associated with a participant's self-appraised job performance, and (c) consistent with an affective spillover hypothesis, degree of loving feelings for a current romantic partner was positively associated with an individual's own level of intrinsic work motivation, job involvement, and satisfaction with his or her type of work. Results are discussed in light of Pierce et al.'s (1996) model, and potential study limitations are addressed.
