THE USE OF BEHAVIORAL ASSESSMENT TO PRESCRIBE AND EVALUATE TREATMENTS FOR SEVERELY HANDICAPPED CHILDREN

Behavioral assessment procedures were used to prescribe and evaluate treatments of maladaptive behavior for 2 children with severe multiple handicaps. In Experiment 1, the results of an assessment of reinforcer preference were used in conjunction with a functional analysis of the conditions maintaining self-injurious behavior to prescribe a treatment for a child with severe disabilities. The treatment procedure involved the use of a pressure-sensitive microswitch to activate reinforcing stimuli during two solitary conditions, during which self-injurious behavior had occurred at high rates. The results were evaluated with a multiple baseline across settings design and indicated that self-injury decreased with concomitant increases in microswitch activation. Results were maintained at 6 weeks, 8 weeks, and 6 months. In Experiment 2, the results of behavioral assessments of reinforcer preference and self-injurious behavior were combined to develop a treatment for a second severely handicapped child, who exhibited high rates of self-injury in demand situations. This treatment was evaluated with a multiple baseline across tasks design and resulted in the elimination of self-injury for up to 15 months.     

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.     

The nature of control by spoken words over visual stimulus selection.

Eight retarded adolescents were trained to select one (a trained S+) of two visual stimuli in response to a spoken word (a trained word). Two different visual stimuli alternated randomly as the S-. To determine if the spoken work was merely a temporal discriminative stimulus for when to respond, or if it also specified which visual stimulus to select, the subjects were given intermittent presentations of untrained (novel) spoken words. All subjects consistently selected the trained S+ in response to the trained spoken word and selected the previous S- in response to the untrained spoken words. It was hypothesized that the subjects were responding away from the trained S+ in response to untrained spoken words, and control by untrained spoken words would not be observed when the trained S+ was not present. The two visual S- stimuli selected on trials of untrained spoken words were presented simultaneously. The untrained spoken words presented on these trials no longer controlled stimulus selections for seven subjects. The results supported the hypothesis that previous control by spoken words was due to responding away from the trained S+ in response to untrained spoken words.     

Examining the Use of Sex to Cope in a Forensic Sample

The authors examined differences between sexual and mentally disordered offenders on the Coping Using Sex Inventory. Sexual offenders were more likely to use sex to cope with negative life events but did not use all forms of deviant sexual activity.     

Ernst Kris and the art of the mentally ill1

Ernst Kris, a gifted art historian as well as an eminent psychoanalyst, had little regard for the aesthetic value of the spontaneous artistic products of the mentally ill, considering them to be of interest only for the insight they might provide about the patient's psychopathology and unconscious conflicts. Recent scholarship and developments in the art world warrant a critical review of his position, which appears to have derived from his adherence to classical and Renaissance criteria. The works of two untrained and psychiatrically disturbed artists are offered as evidence of their potential aesthetic worth.     

智障儿童和正常儿童外显记忆与内隐记忆的比较研究

本实验采取加工分离程序(PDP)对38名弱智儿童的外显记忆与内隐记忆进行研究,并与47名正常儿童进行比较,结果认为:(1)正常儿童外显记忆明显优于弱智儿童,但在内隐记忆方面,正常儿童与弱智儿童没有显著差异;(2)本实验中,年龄对内隐记忆和外显记忆均没有影响。研究结果对弱智儿童的教育方面有启示作用;另外,PDP实验由于其本身的复杂性,在对特殊人群进行施测时,需要特别注意。     

Sectioned offenders presenting with enduring mental illness: a study exploring behaviors indicative of bullying

Logit and logistic regression analyses were employed to explore the nature, extent and predictors of behaviors indicative of "being bullied" and of "bullying others" in a sample of 125 adult male offender-patients sectioned for enduring mental illness and detained within a high-secure psychiatric hospital. The study addresses the lack of research into this specialized population to date, with a subsidiary aim of comparing the results directly with a previous study conducted with a population of adult male personality-disordered offender-patients (n = 53). Participants were required to complete a self-report behavioral checklist (Direct and Indirect Patient behavior Checklist-Hospital version Revised). The prediction that indirect (subtle) aggression would be reported more frequently than direct aggression was supported in relation to perpetration estimates, with evidence such aggression was also more prevalent among personality-disordered than mentally ill offender-patients. As predicted verbal aggression was the most commonly reported direct behavior. Although it was predicted that those perpetrating aggression would present with increased experience with secure settings this was only supported with regard to bully-victims. Contrary to the prediction made, those victimized did not present with less experience of secure settings. Consistent with the hypothesis, bully/victims were predicted by increased negative behavior toward staff and hospital rules. The results are discussed in relation to the environment in which the aggression is taking place with the implications for practice and future research outlined.     

EFFECTS OF COMMUNITY-BASED,VIDEOTAPE, AND FLASH CARD INSTRUCTION OF COMMUNITY-REFERENCED SIGHT WORDS ON STUDENTS WITH MENTAL RETARDATION

Community-referenced sight words and phrases were taught to adolescents with mild and moderate mental retardation using three instructional methods in two locations. Words were presented on flash cards in a school setting, on videotape recordings in a school setting, and on naturally occurring signs in the community. During each session, participants were taught one third of the words in each of these conditions and were then tested at the community sites. A constant prompt delay procedure was used to promote stimulus control to the experimenter's cue initially and then to transfer control to the textual stimuli used for training. A multiple baseline across participants design was employed. Results showed rapid acquisition of the community-referenced sight words in all three training conditions and generalization from the flash card and videotape conditions to the community sites.     

Negative social interactions,distress, and depression among those caring for a seriously and persistently mentally III relative

Investigated both positive and negative social interactions and their effect on mental health for 106 individuals caring for a seriously mentally ill family member. Results from mixed-model (hierarchial and stepwise) multiple regression analyses in which caregiver age, socioeconomic status, caregiving demand, and severity of patient symptoms was controlled showed that negative social interaction accounted for a significant portion of variance in the caregivers' feelings of distress and depression. Moderated multiple regression analyses showed that under conditions of high negative interaction, the relationship between demand and distress was intensified. Implications of these findings for the conceptualization and measurement of negative social interaction as well as its clinical implications were discussed.
