A behaviour modification technique for the hyperactive child

This paper describes a procedure for the conditioning of attending behaviour in a brain-injured hyperactive boy.

Observations of the behaviour of two hyperactive children were made in the classroom setting. These observations were made from an observation bootn adjoining the classroom and provided data on the frequency of occurrence of the following high rate responses: walking, talking, distraction, “wiggling”. Each child was observed for a minimum of ten minutes a day, four days a week. Following several weeks of baseline observation, the conditioning procedure was begun with the expel imental subject. The conditioning trials took place in the classroom setting. During each time interval in which one of the high rate responses did not occur, S received an auditory stimulus (secondary reinforcer). This auditory stimulus had previously been paired with the delivery of candy and pennies. The stimulus was dispensed by a radio device which activated an earphone worn by the subject. At the end of each conditioning trial, S received whatever candy or pennies he had “earned”.

The data show that the control subject showed no significant change in the frequency of occurrence of the high rate responses during the three month period. The experimental subject showed a significant decrease in non-attending behaviour. This reduction in rate was maintained over a four week extinction period.     

Sex differences in acting out chronic undifferentiated schizophrenics

29 male and 21 female chronic undifferentiated schizophrenics were classified as aggressive or nonaggressive on items of a behaviorally anchored checklist completed by ward personnel plus adjunctive measures of behavior during institutionalization. Women were rated as significantly more aggressive than men. The women engaged in more hostile acts, destroyed more property, were more verbally abusive, and were more uncooperative with staff and other patients than men. The results are discussed in terms of possible sex differences in diagnosis, severity of symptoms, age of onset, and admission/discharge practices.     

Reducing delusional speech in chronic, paranoid schizophrenics

Four schizophrenic patients with paranoid and grandiose delusions who had been hospitalized for an average of 17 yr were exposed to social reinforcement contingencies in a multiple baseline design. During the baseline period, each patient was interviewed for four 10-min sessions each day. The elapsed time from onset of conversation to onset of delusional talk was recorded. At the end of each day, the patients engaged in a 30-min informal chat with a nurse-therapist while relaxing with coffee, snacks, and cigarettes. The intervention introduced two contingencies: (1) The 10-min interviews were terminated as soon as the patient began talking delusionally; (2) The patients earned time for their evening chat by talking rationally during their daytime interviews. Increases of from 200 to 600% in the amount of rational talk exhibited during the interviews occurred as the contingencies were introduced for each patient sequentially over time. These increases were maintained in three patients when the amount of reinforcement was halved, but declined when the patients were confronted directly with their delusional ideas. A modest amount of generalization occurred from the day-time interviews to the evening chats but did not extend to the behavior of the patients on the ward.     

Exploring the meaning of participation in a community art project: A case study on the Seeming project

In Australia, community art has drawn significant research attention in regard to its potential as a community development strategy. Despite the fact that researchers have presented evidence for the positive developmental outcomes of participation in community art projects, a gap remains in understanding how and why people's participation in a community art project can lead to those positive outcomes. This research explored the meaning of participation in a community art project from the vantage point of the people who experience it. Ten participants were interviewed about their participation in a community art project (The Seeming) held in Bendigo, Australia. Following thematic analyses we identified three themes of how participants viewed their participation in a community arts project. These themes included giving voice to the silenced, creation of social connections and challenging and reproducing stereotypes. Participation means coming together and the findings highlight the potential of community arts projects for promoting the creation of new relationships and new stories about community. However, there are also problematic stories about self and others that were not deconstructed. It is argued that the settings in which different groups join can be meaningfully extended if there is an explicit concern with consciousness raising and deconstruction of normative stories.

A deficit of primary affective facial expression independent of bucco-facial dyspraxia in chronic schizophrenics

Abstract

Chronic schizophrenics are known to manifest a deficit of categorisation and recognition of primary emotional facial expression despite intact recognition of face identity. An equivalent deficit of expression of the same primary facial emotions in schizophrenics has not been clearly established. Twenty chronic hospitalised schizophrenics and 20 normals were therefore tested on tasks of facial emotional expression upon verbal command, of facial emotional expression imitation, and of non-affective bucco-facial praxic imitation. Results indicate that chronic schizophrenics do manifest a deficit of facial emotion expression which can best be explained by task parameters, such as verbal cueing of emotions, perceptual recognition, and bucco-facial dyspraxia in decreasing order of importance. The deficit does not appear to result from neuroleptic or anticholinergic medication nor length of hospitalisation or disease.
