THE TREATMENT OF COVERT SELF-INJURY THROUGH CONTINGENCIES ON RESPONSE PRODUCTS

Assessment and treatment of covert self-injurious behavior are complicated because it is difficult to quantify and apply differential consequences to covert responses. In this study, both tangible and social reinforcers were identified using reinforcer assessment methods. These reinforcers were then provided contingent upon the absence of tissue damage identified during physical examinations, resulting in near 100% success in physical assessment checks that was maintained over 10 months.     

ASSESSMENT AND TREATMENT OF DESTRUCTIVE BEHAVIOR MAINTAINED BY STEREOTYPIC OBJECT MANIPULATION

In the current investigation, 2 participants with mental retardation displayed property destruction and stereotypy, and both responses involved the same materials (e.g., breaking and tapping plastic objects). Three experiments were conducted (a) to indirectly assess the functions of these two responses, (b) to determine their relation to one another, and (c) to develop a treatment to reduce the more serious behavior, property destruction. In Experiment 1, previously destroyed materials were either present or absent, and their presence reduced property destruction but not stereotypy. In Experiment 2, matched toys (ones that produced sensory stimulation similar to stereotypy) were either present or absent, or were replaced by unmatched toys (for 1 participant). Matched toys produced large reductions and unmatched toys produced small reductions in property destruction and stereotypy. In Experiment 3, attempts to pick up undestroyed objects were either blocked or not blocked while matched toys were continuously available. Response blocking reduced property destruction (and attempts), prevented stereotypy, and increased manipulation of matched toys. These results suggest that the two aberrant responses formed a chain (e.g., breaking and then tapping the object), which was maintained by the sensory consequences (e.g., auditory stimulation) of the terminal response, and that previously destroyed material or matched toys made the initial response (property destruction) unnecessary.     

DEPRESSION IN WOMEN AS RELATED TO ANGER AND MUTUALITY IN RELATIONSHIPS

Self-in-relation theory (Jordan, Kaplan, Miller, Stiver, & Surrey, 1991) proposes that a lack of mutuality in women's relationships predisposes them to depression and inhibits their ability to acknowledge and address effectively emotions such as anger. Research linking anger to depression has not examined women's emotional expressivity within the context of their partner relationships. Women's depression as a function of both their level of anger suppression or inappropriate anger expression and the level of perceived relationship mutuality was studied in a sample of 223 college women, aged 18 to 54. Lower levels of mutuality and higher levels of suppressed or inappropriately expressed anger were associated with depression. Moreover, mutuality made contributions to predicting depression beyond that explained by anger. Lower mutuality was also related to higher anger suppression, but unrelated to inappropriately expressed anger.     

Nonstranger sexual aggression: A discriminant analysis of the psychological characteristics of undetected offenders

Sex Roles - Rape is an underreported and underconvicted crime. Therefore, many highly sexually aggressive men are missed by research employing judicial identification for sample selection. The...     

Decreased helpfulness with increased group size through lessening the effects of the needy individual's dependency1

The present experiment attempted to integrate the research on helpfulness in which subjects work for someone else in an artificial laboratory setting (Berkowitz & Daniels, 1963; Berkowitz, 1972) with the bystander-intervention-in-emergencies studies often carried out under more realistic conditions (e.g., Latané & Darley, 1970; Schwartz & Clausen, 1970; Clark & Word, 1972). Fifty-six university women in a 2 × 2 factorial design were led to think they were working for a same-sex peer who could win a cash prize, although there was “nothing in it for them.” Half were told that the other's chance of getting the prize was greatly dependent upon their effort while the remaining participants were informed that the other did not need their-work very much. Moreover, half of the subjects thought they were the only ones working for the other whereas the remaining people believed there were two other co-workers and that the output from all three would be averaged. It was expected that the participants would feel the greatest personal responsibility to help the other and would work hardest for her when she was greatly dependent upon their productivity and they were the only worker, while the subjects would feel the lowest level of personal responsibility for their peer and would be least helpful to her when she was not particularly dependent upon them and there were two other co-workers. The findings are generally in accord with these expectations.     

The relationship between frontalis muscle activity and self-reports of headache pain

The relationship between levels of frontalis muscle activity and self-reports of pain was evaluated in two studies. In Study I frontalis muscle activity and self-reports of pain collected during biofeedback treatment of muscular contraction headache clients were correlated. In Study II frontalis EMG activity was increased and decreased using biofeedback techniques while concurrent reports of headache pain were recorded. The results of Study I indicated a significant relationship between EMG activity and reported headache pain for only two of the five subjects studied. The biofeedback procedures in Study II were associated with reliable increases and decreases in EMG activity. Concordance between EMG and pain reports occurred only during the EMG increase condition. Overall correlations were significant for one of the 2 subjects. The results suggest that EMG activity may not be sufficient to account for pain reports in all chronic headache clients, and variables other than EMG activity may be influencing reports of pain in some patients.     

A test of the hypothesis that Cronbach's alpha reliability coefficient is the same for two tests administered to the same sample

In measurement studies the researcher may wish to test the hypothesis that Cronbach's alpha reliability coefficient is the same for two measurement procedures. A statistical test exists for independent samples of subjects. In this paper three procedures are developed for the situation in which the coefficients are determined from the same sample. All three procedures are computationally simple and give tight control of Type I error when the sample size is 50 or greater.The author is indebted to Jerry S. Gilmer for development of the computer programs used in this study.     

An Assessment of the Effectiveness of Two Tactics to Reduce Arousal in Crowded Mass Transit Settings1

Studies of crowding in various settings have shown that individuals are aroused and frequently suffer from ill health. Several studies have shown that it is possible to successfully intervene in residential, shopping, and classroom settings to reduce the negative effects of crowding. The present laboratory experiment assessed the effectiveness of two tactics commonly used by passengers in crowded mass transit settings. Results indicated that the two tactics, reading a newspaper or talking to others, failed to reduce arousal. An explanation for the failure of these tactics is offered.
