Display vs. memory search for digits and faces among mentally handicapped and MA-matched non-handicapped youngsters

This experiment was designed to explore possible explanations for handicapped individuals' characteristically poor performance on memory scanning tasks. Independent variables included group (mentally handicapped vs. non-handicapped), type of search (display vs. memory), type of stimuli (digits vs. pictures of unfamiliar boys' faces), and load (2, 3, or 4 items to be searched). Results indicated that handicapped and non-handicapped groups did not differ when searching displays but did when searching memory, which suggested that the handicapped group's most significant impairment was specific to some aspect of memory search. Handicapped youngsters were also hindered by increasing loads more than control youngsters were. This result as well as impairment in memory search may have been due to handicapped youngsters' relatively short visual spans. The groups did not differ in their response to the two types of stimuli, faces and digits. Facial search was a considerably more demanding task than digit search for handicapped and normal children.     

Stimulus overselectivity in autistic,trainable mentally retarded,and non-handicapped children: Comparative research controlling chronological (rather than mental) age

Much of the comparative research on stimulus overselectivity has been flawed by either failure to control for chronological age and language ability of the subjects or reliance on the controversial technique of matching on mental age. The present study investigated the prevalence of overselectivity in autistic, trainable mentally retarded, and non-handicapped children demonstrating some expressive speech. The ages of the children were between 6 years-6 months and 9 years-3 months. Thus, chronological age and language ability were controlled, rather than allowed to vary unsystematically. Results indicated no significant differences between the autistic and TMR samples, but significant differences between the handicapped samples and the non-handicapped group. Some, but not all, of the handicapped children displayed overselectivity.     

Differential Predictability: Selection of Handicapped and Non-handicapped

This research is concerned with the question of differential predictability of handicapped and non-handicapped subgroups. The specific question posed was: Is the performance of non-handicapped subgroups of skilled, clerical, and non-skilled workers more predictable than that of handicapped subgroups when aptitude measures are used as predictors? Correlations between scores on selected scales of the GATB and a composite performance criterion were obtained for each of the subgroups. Results showed a pattern of consistently lower validities for the handicapped which suggests that aptitude measures typically used in selection may not be appropriate for the handicapped, and that validity coefficients may be diluted by the inclusion of this subgroup with the non-handicapped in validity studies.     

Cognitive style and moral judgement in mentally handicapped and non-handicapped children of equal mental age*

Forty-seven mentally handicapped and 47 non-handicapped children matched on mental age were assessed with Kagan's Matching Familiar Figures Test (MFFT) and a Piagetian measure designed to elicit moral judgements. No significant differences were observed in the error and latency scores between the two groups nor in the proportion of reflective, impulsive, fast/accurate or slow/inaccurate individuals. The results also indicated that the subjects did not differ in their level of moral judgement; although reflectives made moral judgements on the basis of intention rather than consequence. Moral judgement was not significantly correlated with performance on the MFFT. The findings were interpreted as being consistent with Zigler's developmental concept of cultural-familial retardation and suggesting that the ability to solve moral dilemmas appears to involve cognitive capacities.     

Taking visual disability into account: Explaining failure to experts and non-experts

The present study was designed to investigate visually handicapped students' explanations for failure when the motive to maintain or enhance self-esteem was in conflict with the motive to present a favorable social image. Subjects experienced manipulated failure in a text comprehension task and were subsequently asked to give causal and responsibility attributions in the presence of either a visually handicapped or a non-handicapped experimenter. It was expected that visually disabled participants would claim a handicap-bonus from the non-handicapped experimenter by explicitly presenting non-defensive attributions and accounts as well as handicap-related responses, while defensive explanations should be more pronounced when faced with a blind experimenter. The data provide support for the existence of presumed social expectations as determinants of individuals' verbal self-presentations.     

Social interactions among teachers, handicapped children, and nonhandicapped children in a mainstreamed preschool

The emotional tone and social integration of two mainstreamed preschool classes were studied to determine whether or not the findings of an earlier study would be repeated. Although most variables showed no differences between handicapped and nonhandicapped children's peer-directed and teacher-directed behaviors, result did suggest that, particularly in one class, nonhandicapped children tended to selectively interact with other nonhandicapped (as opposed to handicapped) children when engaging in more complex (associative) social play. Handicapped children did not show the same tendency to interact more within their own group. At the same time, handicapped children received more help and affection from peers, and were more effectionate towards peers, than nonhandicapped children. Teachers refused handicapped children's requests and corrected their behavior more often; however they also gave them more help and more affection than nonhandicapped children. The results were generally congruent with those of an earlier study but did show more segregation on the part of nonhandicapped children.     

THE DEVELOPMENT OF COMMUNICATION SKILLS IN PHYSICALLY HANDICAPPED CHILDREN

The present study was primarily concerned with the communication skill development of physically handicapped children. Since these children often are denied contact with peers because of their disabilities, it was suggested that they may be unable to develop the perspective-taking ability necessary for adapting communication to a specific listener. It was also suggested that the increased contact provided by moving the handicapped into regular public school classrooms may help alleviate this problem. First-, third-, and sixth-grade children, handicapped and nonhandicapped, with and without the others in their classes, were tested on their listener-adaptation abilities in general and their adaptation to handicapped children, using pictures as stimuli for messages. The results support the hypothesis that handicapped children are deficient in listener adaptation. Classroom association with “normals” seems to improve this, but does not raise them to the level of their nonhandicapped peers. Nonhandicapped children are unable to adapt to handicapped children, and contact with the handicapped does not seem to improve this situation. Being in an integrated class seems to have some positive effects on handicapped children and few effects on the nonhandicapped.     

Training severely and profoundly mentally handicapped nocturnal enuretics

The problem of nocturnal enuresis in the institutionalized mentally handicapped is a major one which reduces independence in many handicapped adults and has major implications for hospital resources. Much work, which has looked at initial success rates, relapse rates, and factors involved in these, has been carried out with non-handicapped populations. However, there have been remarkably few such studies with the mentally handicapped. A study is reported in which five severely and profoundly mentally handicapped adolescents or young adults were successfully trained over periods ranging from 18 to 92 weeks. Several interesting features of the data are discussed.     

Étude du style interactif maternel et des compétences sociocommunicatives des enfants. Une étude comparative entre enfants porteurs de trisomie et enfants typiques

The goal is to explain Down syndrome social language disturbances. Down's syndrome and non-handicapped children were observed interacting with their mothers. We compared 22 dyads with Down syndrome children and 22 dyads with non-handicapped children. Down's syndrome children were matched on mental age with non-handicapped children (4 to 24 months). Social context, mothers' behaviours and children's social communicative competences were evaluated. Interaction behaviours in the mothers of DS children differ from those of mothers of non-handicapped children. DS communicative competences also are different from those in non-handicapped children. We argue that mothers' behavioural interaction in the dyads with DS children can be an aspect of social communicative disturbances of DS children.     

PEER INTERVENTION EFFECTS ON COMMUNICATIVE INTERACTION AMONG HANDICAPPED AND NONHANDICAPPED PRESCHOOLERS

A peer-mediated intervention designed to promote communicative interaction on the part of three language-delayed children was evaluated. Two nonhandicapped preschoolers were taught strategies thought to facilitate interaction and were prompted to use these strategies during free play with three handicapped classmates. The intervention resulted in higher rates of interaction for each of the handicapped children that persisted above baseline levels after teacher prompting was withdrawn.     

Favourite objects of autistic children

Favourite objects (FOs) of autistic children were compared with the FOs of healthy preschool and school children as well as mentally handicapped children. Three clusters of objects were obtained for normal children (comprising primary transitional objects and their forerunners, secondary transitional objects, and non-cuddly toys). When autistic children and mentally handicapped children were included, a fourth cluster of deviant objects was found. Frequency distributions of the two handicapped groups in the clusters were similar. Similarities between the two handicapped groups were also found within each cluster. The occurrence of secondary transitional objects was rare in the handicapped groups. The characteristics of "autistic" FOs reported in earlier case studies (e.g. being hard, often having an exciting effect, not being used in their adequate functions) were typical only of objects in the fourth cluster.     

Waking and dreaming: related but structurally independent. Dream reports of congenitally paraplegic and deaf-mute persons

Models of dream analysis either assume a continuum of waking and dreaming or the existence of two dissociated realities. Both approaches rely on different methodology. Whereas continuity models are based on content analysis, discontinuity models use a structural approach. In our study, we applied both methods to test specific hypotheses about continuity or discontinuity. We contrasted dream reports of congenitally deaf-mute and congenitally paraplegic individuals with those of non-handicapped controls. Continuity theory would predict that either the deficit itself or compensatory experiences would surface in the dream narrative. We found that dream form and content of sensorially limited persons was indifferent from those of non-handicapped controls. Surprisingly, perceptual representations, even of modalities not experienced during waking, were quite common in the dream reports of our handicapped subjects. Results are discussed with respect to feedforward mechanisms and protoconsciousness theory of dreaming.     

Play behaviors of handicapped preschool children in the presence and absence of nonhandicapped peers

Sixteen minimally handicapped children and 18 nonhandicapped children were observed playing as separate classes and as a combined group on their preschool playground. Play behaviors directed toward self, toys, teachers, and peers were recorded using a time sampling procedure. Repeated measures analyses revealed that: (1) handicapped children engaged in less peer-directed and more teacher-directed behaviors than the similar chronological age but developmentally more advanced normal children; (2) a comparison between a subsample of normal and handicapped children who were approximately equivalent on developmental age suggested that the normal children only vocalized more often; (3) when integrated with the normal children, handicapped children engaged in more peer-directed and less teacher-directed behaviors than when playing in the non-integrated situation; (4) during the combined group play situation, normal children directed more behaviors to their own classmates while handicapped children directed approximately equal amounts of behavior to their own classmates and to their normal peers. These results suggest that the normal children were not negatively affected and the handicapped children were positively affected by the integrated play situation.     

A follow-up study of young cerebral palsied patients Some psychological, educational and vocational aspects

Abstract.— In a follow-up study of 39 non-oligophrenic spastic adolescents and young adults it was found that 85% attended normal schools, the rest went to schools for physically or mentally handicapped. If retarded children with learning difficulties were left out of account, there were no more than 10% regular problem cases, an incidence which is very close to what is found among ordinary, non-handicapped Danish school children.-With regard to vocational career, nearly 80% were estimated to be able to obtain and remain in open employment. About one third had experienced rather pronounced vocational problems either because of physical weakness and slowness, or because of personality disturbances or intellectual retardation. Females appeared generally more content with and successful in their jobs than the males. There was an overrepresentation of clients with a mild physical handicap in the problem group, indicating that it may be difficult to occupy such a "marginal" position with its easy accs to comparison and competition with the socalled normal standards.-A close relationship was found between the data from the original psychological evaluation and the course of schooling. In contrast, there was a low agreement between the childhood reports and the follow-up employment data.

Assessment and attempted modification of future teachers' attitudes toward handicapped children.

In a study designed to determine whether future teachers have negative sttitudes toward groups of exceptional children based upon the labels attached to these children, 13 special education majors and 32 students majoring in other fields of education were administered the Personal Attribute Inventory at the beginning and conclusion of an introductory course in special education. Results for labels, physically handicapped, educable mentally handicapped, and learning disabled, indicated that the latter two were evaluated significantly less positively than the first on both pre- and post-course testings. There were no significant differences between the respondents' pre- and post-course ratings of the three labels. Interestingly, special education majors were significanlty more positive in their pre- and post-course evaluations than non-special education majors. These findings certainly are not supportive of "mainstreaming" children who have been categorized as either learning disabled or educable mentally handicapped.     

Acquisition and performance difference between normal and mentally handicapped adults on a complex assembly task

Several single studies concerned with work training with the mentally handicapped have been reported in the literature (Bitter & Bolanovich, 1966; Huddle, 1967; Gold, 1969; Screven, Straka & Lafond, 1971). Most have been concerned with issues of acquisition and motivation to perform. No studies have been reported which focus on the evaluation of different techniques of training or which assess rate of acquisition against that of non-handicapped controls. The aim of this experiment is twofold. It uses a complex task, analysed by MTM-2, to enable comparison between the performances of mentally handicapped adults and adults from a 'normal' population, in the acquisition of new work skills. Various strategies of training were compared and the increase in the rate and quality of performance following acquisition was measured for both, in terms of speed and accuracy of production. Results add further support for the notion that the potential of mentally handicapped individuals is commonly underestimated. It is hoped that the findings provide a basis from which further experiments can be developed and evaluated.     

Project early: A program at Oakland University to retrain teachers to work with young handicapped children

Mandatory education and mainstreaming of handicapped children creates demands and opportunities for teachers and schools. Project Early is a special graduate program at Oakland University designed to retrain teachers to work with young handicapped children.     

Incremental Benefits of a Daily Report Card Intervention Over Time for Youth With Disruptive Behavior

This study examined the percentage of children who respond positively to a daily report card (DRC) intervention and the extent to which students achieve incremental benefits with each month of intervention in a general education classroom. Participants were 66 children (87% male) with attention-deficit hyperactivity disorder or disruptive behavior problems who were enrolled in a school-based intervention program in rural, low-income school districts in a Midwest state. The DRC was implemented by each child's teacher, who received consultation from a graduate student clinician, school district counselor, or school district social worker. A latent class analysis using growth-mixture modeling identified two classes of response patterns (i.e., significant improvement and significant decline). Results indicated that 72% of the sample had all of their target behaviors classified as improved, 8% had all of their targets classified as declining, and 20% had one target behavior in each class. To examine the monthly incremental benefit of the DRC, individual effect sizes were calculated. Results for the overall sample indicated that most children experience a benefit of large magnitude (.78) within the first month, with continued incremental benefits through Month 4. The differential pattern of effect sizes for the group of improvers and the group of decliners offer data to determine when and if the DRC should be discontinued and an alternative strategy attempted. Evidence-based guidelines for practical implementation of the DRC are discussed.     

Two types of feedback in teaching swimming skills to handicapped children.

Two types of feedback (non-task-specific praise and task-specific praise plus corrections) were used in a counterbalanced design to teach two swimming skills to each of four handicapped children. The children were grouped into pairs, and each member of a pair received the alternate type of feedback for the same skill. In every case, faster and more complete acquisition was found to result from task-specific praise plus corrections.
