A COMPREHENSIVE EVALUATION OF REINFORCER IDENTIFICATION PROCESSES FOR PERSONS WITH PROFOUND MULTIPLE HANDICAPS

We evaluated comprehensively a preference assessment for identifying reinforcers for persons with profound multiple handicaps. Four experiments were conducted involving 18 individuals. Results of Experiment 1 replicated previous findings in that the assessment identified student preferences for respective stimuli, and caregiver opinion of preferences did not coincide with the systematic assessment. Results of Experiment 2 indicated highly preferred stimuli were likely to function as reinforcers in training programs, whereas stimuli not highly preferred did not function as reinforcers. Results of Experiment 3 suggested the 12 stimuli used in the assessment represented a comprehensive stimulus set for identifying preferences, although the utility of the set sometimes could be enhanced by caregiver opinion. Results of Experiment 4 indicated the assessment identified preferences likely to be maintained over time. Overall, results are discussed in terms of identifying limits and alternatives to a behavioral teaching technology when applied to persons with profound multiple handicaps.     

The Measurement of Self-Esteem, Stress-Related Life Events, and Locus of Control Among Unemployed and Employed Blue-Collar Workers

The purpose of this study was to measure the self-esteem, stress of life events, and locus of control among unemployed and employed blue-collar workers. It was hypothesized that (a) being unemployed decreases an individual's self-esteem, (b) being unemployed increases an individual's stress level by experiencing significant life changes, and (c) being unemployed increases an individual's external locus of control orientation. The study was conducted in a production/manufacturing organization, utilizing a systematic random sampling procedure that yielded 562 subjects. The results from the collected data did not support Hypothesis A or C. A significant change with stress in conjunction with life events was found but was mediated by several factors, including age and a nonsignificant correlation between time laid-off and stress levels. The study suggests that an individual's reaction to unemployment does not appreciably affect their self-esteem and locus of control when compared to the employed.     

Making choice a routine part of mealtimes for persons with profound mental retardation

Despite increased recognition of the importance of providing routine choice opportunities for persons with severe handicaps, this population continues to experience a typical lack of such opportunities. We evaluated a program for increasing the amount of choices made during routine mealtimes by persons with profound mental retardation and minimal communication skills. The choice provision program, involving systematic presentation of alternative food and drink items in a step-wise fashion during the course of the meal, was implemented with three persons in a residential facility. Results indicated that after implementation of the choice program, all three participants made consistently more choices concerning the foods and beverages they consumed relative to baseline. The choice provision program was conducted without extending the amount of time typically allotted to mealtime within the residential setting. Results are discussed in regard to additional research needed to continue developing means of assisting persons with profound mental retardation to exert control over meaningful events in their lives.     

Cognitions, affect, and behavior following uncontrollable outcomes: A response to current human helplessness research

A series of articles in the Journal of Personality challenge several central assumptions of the reformulated learned helplessness model: that perceptions of uncontrollability, awareness of noncontingency between responses and outcomes, and attributions made about the outcome are necessary to explain learned helplessness effects. The present article addresses the validity of this challenge through a consideration of the methodology employed in these and other traditional studies of human helplessness conducted in the laboratory. We maintain that although performance deficits can be demonstrated reliably following exposure to uncontrollable outcomes, a number of factors other than expectations of future uncontrollability (i.e., learned helplessness) may be responsible for these effects. In addition, demands of the experimental situation may prevent subjects from admitting their true underlying thoughts and feelings regarding the manipulations employed. Finally, the current use of artificial laboratory paradigms may unnecessarily restrict the study of a complex psychological phenomenon such as learned helplessness. We suggest that future researchers employ paradigms that more closely parallel real world situations to which they hope to generalize, or utilize naturally occurring uncontrollable life events to study the problem. In addition, we argue that future research should broaden its focus beyond attributions to explore other mediators of human helplessness.     

USE OF A SELF-RECORDING AND SUPERVISION PROGRAM TO CHANGE INSTITUTIONAL STAFF BEHAVIOR

The use of a self-recording and supervision program to increase interactions between direct care staff and profoundly retarded persons in a state residential facility was investigated. Following baseline, staff were provided with instructions regarding what to self-record, criteria for how many interactions to record, and a prepared card on which to make the recordings. Throughout the study, the staff supervisor monitored intermittently staff-client interactions. Observations indicated that when the staff recorded their interactions with clients in a loosely structured dayroom setting, the rate of interactions increased noticeably for each staff person. Behavioral ecology measures indicated that other staff responsibilities, such as maintaining the cleanliness of residents and the physical area, were not affected detrimentally when social interactions increased and actually showed small improvements. Additionally, small decreases in resident self-stimulatory and disruptive/aggressive behaviors occurred when the rate of social interactions from staff persons increased. Follow-up measures indicated that the rate of staff self-recording was variable, but when staff did self-record, the increased rate of staff-client interactions maintained.     

Chunking in recall of symbolic drawings

Three experiments explored memory for symbolic circuit drawings using skilled electronics technicians and novice subjects. In the first experiment a skilled technician reconstructed circuit diagrams from memory. Recall showed marked “chunking”, or grouping, by functional units similar to Chess Masters’ recall of chess positions. In the second experiment skilled technicians were able to recall more than were novice subjects following a brief exposure of the drawings. This advantage did not hold for randomly arranged symbols. In the third experiment the size of chunks retrieved systematically increased with additional study time. Supplementary analyses suggested that the chunking by skilled subjects was not an artifact of spatial proximity and chunk statistics, and that severe constraints are placed on any explanation of the data based on guessing. It is proposed that skilled subjects identify the conceptual category for an entire drawing, and retrieve elements using a generate-and-test process.     

Children at risk for delinquency: A follow-up comparison of aggressive children and children who steal

This study compared the follow-up incidence of court-recorded nonstatus offenses for three groups of adolescent children. These children had been seen 2 to 9 years earlier for problems with aggression in the home (N = 21), for stealing problems (N = 25), or for normative comparisons (N = 14). The results showed that 77% of the children with stealing problems had court-recorded offenses. This was significantly higher than the aggressive children, whose rate did not differ from the normative sample. These findings suggested that young aggressive children were not at risk for adolescent court contact. Instead, it was the young child with identified stealing problems who was highly likely to become an official delinquent. It also appeared that parental reports of stealing events constituted a predictive measure of later criminal acts.
