FUNCTIONAL COMMUNICATION TRAINING WITH AND WITHOUT EXTINCTION AND PUNISHMENT

Functional communication training has been reported to be a promising treatment for severe behavior problems. In this study, functional communication training alone and combined with extinction and/or punishment was evaluated for 4 clients with severe retardation, behavior problems, and communication deficits. The participants were inpatients on a hospital unit for treatment of severe behavior disorders. They received individualized interventions based on functional assessment that included reinforcement of a communication response with the same function as their destructive behavior. Results showed that for some patients, functional communication training was not sufficient to produce clinically significant reductions in destructive behavior, and the combination of training plus punishment produced the largest and most consistent reductions.     

VALIDATING PREDICTED ACTIVITY PREFERENCES OF INDIVIDUALS WITH SEVERE DISABILITIES

We examined the accuracy of 24 staff members' predictions of activities preferred by 14 individuals with severe disabilities. For each of 144 activities, staff members assigned a client preference rating of “likes a lot,” “likes,” or “dislikes.” Two activities from each category were randomly selected for each individual with disabilities. Pairs of selected activities were presented to the individuals, who were prompted to choose an activity. Staff members' activity preference ratings correctly predicted the choices made by the individuals with disabilities for 78% of the trials. The more divergent the preference ratings of the paired activities, the more likely staff members were to predict correctly the activity selected by a participant.     

Parental functioning and children's adjustment in families of divorce: A prospective study

This paper prospectively examined relations between marital status, predivorce parenting practices, and children's adjustment, using data from the New York Longitudinal Study (NYLS). Prospective analyses of children's predivorce adjustment indicated that neither boys nor girls showed more problematic behavior prior to parental separation, and only boys had more difficulties after divorce. However, parents of to-be-divorced families reported more difficulties in childcare practices before divorce than did parents of always-married families. Parenting difficulties in to-be-divorced families were found consistently for boys but not for girls. Results suggest that the difficulties found among boys after divorce may be linked with parenting problems that begin before divorce.The authors are indebted to Alexander Thomas and Stella Chess, the original investigators of the project. We also would like to thank Jacqueline and Richard Lerner, and the John D. and Catherine MacArthur Foundation for their efforts in preserving this data base.     

A generalized family of coefficients of relational agreement for numerical scales

A family of coefficients of relational agreement for numerical scales is proposed. The theory is a generalization to multiple judges of the Zegers and ten Berge theory of association coefficients for two variables and is based on the premise that the choice of a coefficient depends on the scale type of the variables, defined by the class of admissible transformations. Coefficients of relational agreement that denote agreement with respect to empirically meaningful relationships are derived for absolute, ratio, interval, and additive scales. The proposed theory is compared to intraclass correlation, and it is shown that the coefficient of additivity is identical to one measure of intraclass correlation.The author thanks the Editor and anonymous reviewers for helpful suggestions.     

CROSS-CULTURAL COMPARISONS ON PSYCHOSEMANTICS OF ICONS AND GRAPHICS

This study is to report a cross-cultural comparison on perceptions of icons and graphics and their relationships. Data were ratings of 10 icons and 10 graphics against 21 bipolar semantic differential scales from 325 college students in three countries, Mexico, Columbia, and Japan. Cross-cultural factor analyses resulted in the identification of four semantic (three affective and one denotative) features, three icon factors, and three graphic factors. Indigenous cultural means of these iconic and graphic factors were computed and used to probe cross-cultural similarities and differences in perceptions. Psychosemantics of icon factors were further predicted by graphic factors through canonical correlation. This study concludes the importance of implicit cultural meanings of nonverbal figures in intercultural communications. The implications of this study are also discussed.     

TRADUCTION ET VALIDATION CANADIENNE-FRANÇAISE DE L'ÉCHELLE DE L'ESTIME DE SOI DE ROSENBERG*

Since the early days of psychology, the self-concept and more specifically global self-esteem has been addressed by numerous researchers in the field. Among the widely used instruments for measuring global self-esteem, Rosenberg's Self-Esteem scale (RSE) has displayed high levels of validity and reliability (Harter 1983; Wylie 1974). Through a brief (10 items) and direct approach, the RSE can be answered quickly by different age and social groups. Considering the good psychometric properties of the RSE mentioned above, and the importance of self-esteem for research in psychology, the purpose of the present four studies was to translate and validate in French the RSE Internal consistency (study 1) and confirmatory factor analyses through LISREL VI (study 2) were conducted with a French-Canadian junior college student population in order to verify the internal consistency and the unidimensional factorial structure of the scale. In addition, the construct validity (study 3) and temporal stability (study 4) of the scale were assessed. Although the present findings are preliminary in nature, they nevertheless support the reliability and validity of the Rosenberg's Self-Esteem scale in French.     

EXTENDED REDUCTIONS IN STEREOTYPIC BEHAVIOR OF STUDENTS WITH AUTISM THROUGH A SELF-MANAGEMENT TREATMENT PACKAGE

The literature suggests that self-management treatment packages have two potential strengths for the reduction or elimination of stereotypic behavior: (a) Self-management may be used for extended periods of time in the absence of a treatment provider, and (b) self-management techniques are easily adapated and used in a wide variety of natural settings. We assessed whether students with severe autistic disabilities could learn to use a self-management treatment package to reduce their stereotypic behavior within a multiple baseline across subjects design with withdrawals. The results showed that all of the students learned to use self-management procedures to reduce greatly levels of stereotypic behavior (typically to zero), and improvement occurred for extended periods of time in new settings without the presence of a treatment provider. The results are discussed in terms of the practical value of the treatment package and in terms of the implications for understanding autism.     

Punished and Nonpunished Responding in A Multiple Schedule in Humans: A Brief Report

Four male subjects responded on a multiple schedule in which responding was maintained by a random interval 20-sec (RI20) schedule of point presentation. Responding was suppressed in alternating components by an added variable ratio 30 (VR30) schedule of point subtractions. Each component was accompanied by distinctive stimulus lights. Subjects were exposed to the multiple schedule from the initial session. Two subjects experienced four 50-min sessions daily (Experiment 1) and the other two subjects participated in one 50-min session daily (Experiment 2). Once responding in the punished components had stabilized, responding in the nonpunished components continued to increase across sessions. Nonpunished responding did not stabilize even after as many as 36 sessions. These results are discussed in the context of previous studies using animals which employed multiple schedules with punished and nonpunished response contingencies.

     

Modeling item responses when different subjects employ different solution strategies

A model is presented for item responses when different subjects employ different strategies, but only responses, not choice of strategy, can be observed. Using substantive theory to differentiate the likelihoods of response vectors under a fixed set of strategies, we model response probabilities in terms of item parameters for each strategy, proportions of subjects employing each strategy, and distributions of subject proficiency within strategies. The probabilities that an individual subject employed the various strategies can then be obtained, along with a conditional estimate of proficiency under each. A conceptual example discusses response strategies for spatial rotation tasks, and a numerican example resolves a population of subjects into subpopulations of valid responders and random guessers.The first author's work was supported by Contract No. N00014-85-K-0683, project designation NR 150-539, from the Cognitive Science Program, Cognitive and Neural Sciences Division, Office of Naval Research.
