The present study investigated the effects of a treatment program on the self-injurious behaviors of a 12-year-old autistic male. Initial observations indicated that these behaviors functioned primarily as escape responses to terminate performance demands. For 1 year the subject received general compliance training with the frequency of demands being systematically increased through consecutive treatment weeks. The subject's self-injurious behaviors were no longer reinforced by his escaping from demands nor did they receive social attention. Compliance to demands and appropriate behaviors in general were positively reinforced. The treatment produced substantial reductions in the rates of self-injurious behaviors and increased compliance. Additionally, the intensity of the subject's self-injurious behaviors decreased over the course of treatment. The present study suggests that the treatment approach is a reliable means of not only reducing self-injurious behaviors but also expanding performance repertoires. 相似文献

A burgeoning area of scientific inquiry uses psychological perspectives to understand traumatic events. This research has led to the identification of psychological symptoms and disorders frequently experienced in response to traumatic events. Many of the events having traumatic effects on large numbers of persons are of interest to political psychologists. Such events include the Holocaust, war, terrorism, captivity, torture, political migration, living as a political refugee, and assassination. Some interpersonal forms of trauma, such as rape and incest, also may be viewed with a political perspective. Although a number of studies have examined psychological consequences of political events, this area of inquiry is rarely explicitly considered within the domain of political psychology. Adopting an explicitly political psychology perspective on traumatic events may enrich our interdisciplinary understanding of these events and inform the design and evaluation of intervention programs to reduce psychological distress resulting from these events. 相似文献

Detection and identification thresholds were obtained for 6- and 10-year-old normal children and normal adults using five-formant synthesized consonant-vowel ([baHdflrfea]) stimuli. Sixyear-old children were found to have poorer detection than adults, just as they do for pure tones. For the identification task, the slopes of the performance-intensity functions were more shallow for 6-year-old children than for 10-year-olds and adults. Consequently, compared with 10-yearolds and adults, 6-year-old listeners require a greater increase in stimulus intensity above detection threshold to identify these stimuli at a high performance level. The influence of acoustic characteristics of the stimuli on all listeners is also discussed. 相似文献

The performances of 22 adult stutterers and 22 adult nonstutterers on motor tasks requiring the graphic reproduction of a sequence of alternating figures following the production of a series of nonalternating figures were studied. The finding that there were no differences in the performance of the two groups on the alternating motor tasks was interpreted as challenging the validity of previous observations that motor perseverative behavior exists in stutterers and is indicative of a central neurological deficit in that population. 相似文献

Over the last few years there has been a tremendous upsurge of research on child victims of trauma. However, very little has been reported on the process of psychotherapy with traumatized children. The purpose of this paper is to assess the role of countertransference and the use of a treatment parameter that has been tried in several individual cases of victimized children and found to be of value. 相似文献

This study investigated the relationships of metal levels and metal combinations to children's classroom behavior. Hair-metal concentrations of lead, arsenic, mercury, cadmium, and aluminum were determined in 80 randomly selected elementary-age children, who were also rated by their classroom teacher on the Walker Problem Behavior Identification Checklist (WPBIC). Parents were interviewed to control for confounding variables that may have affected behavioral development. Regression analysis indicated that the set of metals was significantly related to increased scores on four of the five WPBIC subscales and on the total scale, with lead being a major contributor to four of the six dependent measures. Metal combinations were significantly related to increased scores on the WPBIC subscales measuring acting-out, disturbed peer relations, and immaturity, and on the total scale. A continuing reexamination of metal poisoning concentrations is needed because metal levels and metal combinations previously thought harmless may be associated with nonadaptive classroom behavior. 相似文献
