Impact of interpersonal problem-solving training on preschoolers' social competency

In order to test Shure and Spivack's theoretical position that a child's ability to verbally generate solutions to interpersonal problems and think about their consequences is directly related to the child's behavioral adjustment, preschoolers were tested on verbal problem-solving skills and their classroom behavior was rated by their teachers. Further, their behavior was observed by independent observers. No significant relationship between problem-solving skills and behavior was found. Following assessment, 54 of these children completed an 11-week training program, designed by Shure and Spivack, to improve their ability to think through and verbally generate solutions to interpersonal problems and to examine the possibility of mediation of such training to behavioral improvement. Preschoolers' ability to verbally generate alternative solutions to problems significantly increased due to training, however, this increase did not have an ameliorative effect on behavioral adjustment.     

Developmental differences in reactions to children labeled mentally retarded

In an attempt to examine age-related differences in response to the mental retardation label, 48 4th and 5th graders and 48 11th and 12th graders were told of a child of their own age and sex who was either labeled mentally retarded or unlabeled and who performed either competently or incompetently in giving a report. Incompetent target children were viewed more negatively than competent ones at both grade levels. The mental retardation label had less generalized impacts, leading girls but not boys (a) to cite lack of ability as the reason for a retarded child's failure, and (b) to hold low expectations that retarded targets would hold jobs, marry, or have children. A developmental shift in responses to the label was evident only on a trait perception measure; younger children stigmatized retarded targets, while older children granted special dispensation of a failing retarded child by viewing him or her more positively than a similarly incompetent but unlabeled child. Since only adolescent boys showed special dispensation, even though girls were more generally attentive to the label, both sex and age differences warrant further examination.     

Tower of Hanoi performance of retarded young adults and nonretarded children as a function of solution length and goal state

Three experiments were conducted with the Tower of Hanoi task to assess problem solving ability in 6-, 7-, 8-, and 10-year-old nonretarded children and mentally retarded young adults of varying maturational ages. In Experiment 1 we gradually reduced the number of moves required for solution until subjects could solve the 3-disk tower-ending problem. Although all groups experienced difficulty with the standard 7-move problem, all but the trainable retarded group readily solved the 6-move problem. The trainable group did not reach a comparable level of success until the 4-move problem. On the 7-move problem the retarded groups performed at the level of nonretarded groups that were maturationally $\text{1}\text{1}\text{2}$ to 3 years younger. An analysis of first moves indicated that subject groups differed in the strategies they used to solve the problems. In Experiment 2, practice effects were ruled out as a source of the superior performance on the 6- than on the 7-move problem. In Experiment 3, 7- and 10-year-old nonretarded children and mentally retarded young adults did not differ on 5-move problems in which configuration of the goal states was varied. A comparison of all 5-move problems judged to have the same depth of search requirements indicated that the tower-ending problems were significantly easier to solve than the partial-tower-ending problems, which in turn were easier than the flat-ending problems. A limited depth of search capacity sets boundaries on the use of sophisticated strategies and, to a large extent, accounts for the retarded groups' maturational lag.     

Automatic and conscious processing in retarded and nonretarded adolescents

Educable mentally retarded and nonretarded adolescents participated in incidental learning tasks that emphasized the utilization of processes that were consciously controlled but not deliberately aimed at memory (Experiment 1). Retarded individuals' performance on a standard recognition test was equivalent to that of nonretarded subjects following phonetic encoding and nonstrategic encoding, but was deficient following semantic encoding. Retarded subjects also demonstrated a lower level of performance on a rhyme recognition task. In Experiment 2, retarded subjects provided a pattern of responding identical to that of nonretarded subjects on a picture-word interference task designed to assess automatic processing. The two groups produced equivalent levels of semantic activation. It was argued that the results of the two experiments indicate deficient semantic processing on the part of retarded individuals relative to that of nonretarded individuals that cannot be accommodated by a structural-deficiency model, a developmental-lag model, or a hypothesis that predicts intelligence-related differences only when the task involves the use of deliberate mnemonic strategies.     

Étude des stratégies d’adultes présentant un retard mental dans la résolution de la Twenty Questions Task

A Twenty Questions problem solving Task was given to 30 mentally retarded adults, 30 mentally nonretarded adults matched on chronological age, and 12 mentally nonretarded children matched on cognitive efficiency. Four strategies were identified on the basis of a subject-by-subject analysis. Results showed group differences of frequency in the use of the strategies. Moreover, results indicated that the more frequent strategy used by the mentally retarded adults is the one which consists in identifying the categories without using them to efficiently reduce the problem space. The interpretation of the results as reflecting a conceptual deficit or a chronicle cognitive sub-functioning of the mentally retarded adults depicted in the literature is discussed.     

Influence of item identification on the memory performance of mentally retarded and nonretarded adults

The role of item identification in the memory performance of mentally retarded and nonretarded adults was examined by varying the identification and memory parameters of a sequential same-different task. In Study 1, retarded subjects' identification ability was demonstrated to be less efficient than nonretarded subjects' ability. In Study 2, target duration and interstimulus interval were varied. Memory performance differed between groups, and the memory deficit for retarded subjects was demonstrated to be independent of their identification deficit. The target durations in Study 2 were relatively brief, and in Study 3, the target duration was increased to insure that all subjects could identify the target. Mentally retarded subjects were demonstrated to have a memory deficit. The results were discussed in terms of possible sources of the memory deficit.     

Behavioral expectations of retarded and nonretarded children

Two experiments were conducted to examine the effect of the mental retardation (MR) label on impression formation among retarded and nonretarded children and adolescents. The first experiment, conducted with nonretarded children in a mainstreamed school, indicated that they have pessimistic expectations of retarded children with regard to cognitive and ability-related behaviorsand, to a lesser extent, social behaviors (i.e., getting married). However, their reactions were not as pessimistic nor as “patronizing” as were those demonstrated by college students in previous research. In the second experiment, mentally retarded adolescents indicated that they also have negative behavioral expectations of retarded children, however, their self expectations were negative only for social behaviors. The results suggest that, among retarded persons, the expectations associated with the MR label are negative for social behavior, but apparently less pessimistic for cognitive and ability related tasks.     

The Ability to Encode Facial and Emotional Expressions by Educable Mentally Retarded and Nonretarded Children

The object of the present study was to investigate whether 20 educable mentally retarded (EMR) children matched for verbal mental age on the Peabody Picture Vocabulary Test (PPVT; Dunn, 1965) with 20 nonretarded (NR) controls were adept in identifying emotional facial expressions and producing the equivalent word adjectives. I also reassessed the relationship between the phase of identifying facial expressions (i.e., happy, sad, angry, and scared) and the phase of producing emotional word adjectives, consisting of 16 emotional linguistic constructions (4 short stories for each of the adjectives) between higher in verbal ability educable mentally retarded (HEMR) children and higher in verbal ability nonretarded controls (HNRC) and between low in verbal ability educable mentally retarded (LEMR) children and low in verbal ability nonretarded controls (LNRC). There were no significant differences between EMR and NR children in general, despite the fact that EMR children had deficits in receptive linguistic competence.     

Selectivity and strategy in early search

Early information-processing strategies were examined in a study of very young children's search for hidden objects. Sixteen younger children (mean age: 1 year; 11 months) and sixteen older children (mean age: 2;6) received search problems in which observational and/or verbal information about an object's location was provided. The question of primary interest was how they would respond when given two conflicting sources of information, which differed in modality (observational vs verbal) and in currentness. Both younger and older children showed some use of an appropriate strategy of relying on the more current information, although they did not follow it consistently. Children also showed preferential use of observational over verbal information and response biases favoring the middle location. Age differences were found in children's use of verbal information, in the degree to which they benefitted from practice, and in response biases. These results suggested a distinction between two aspects of the development of search: the acquisition of new search skills and the establishment of appropriate priorities among skills already in the child's repertoire.     

The effects of social reinforcement and task difficulty level on the pleasure derived by normal and retarded children from cognitive challenge and mastery

In order to examine several factors influencing the pleasure derived from mastery, 32 normal first-grade children (mean MA = 7.7) and 32 MA-matched familial mentally retarded children were given puzzles representing four difficulty levels. Half of the children were socially reinforced for their successes and half performed in an experimenter-absent condition. There was more smiling among normal than retarded children, in the social reinforcement than in the experimenter-absent condition, and among girls than boys. The condition effect was greater for girls than boys. In the experimenter-absent condition, normal children displayed more pleasure on the difficult than on the easy puzzles, whereas the trend was just the reverse for the retarded children. Large within-sex differences were found for normal girls only, revealing that one subgroup derived more pleasure from the more difficult puzzles whereas another subgroup enjoyed the easier puzzles more. The findings were discussed in terms of the author's refinement of White's model of effectance motivation.     

The ability to encode facial and emotional expressions by educable mentally retarded and nonretarded children.

The object of the present study was to investigate whether 20 educable mentally retarded (EMR) children matched for verbal mental age on the Peabody Picture Vocabulary Test (PPVT; Dunn, 1965) with 20 nonretarded (NR) controls were adept in identifying emotional facial expressions and producing the equivalent word adjectives. I also reassessed the relationship between the phase of identifying facial expressions (i.e., happy, sad, angry, and scared) and the phase of producing emotional word adjectives, consisting of 16 emotional linguistic constructions (4 short stories for each of the adjectives) between higher in verbal ability educable mentally retarded (HEMR) children and higher in verbal ability nonretarded controls (HNRC) and between low in verbal ability educable mentally retarded (LEMR) children and low in verbal ability nonretarded controls (LNRC). There were no significant differences between EMR and NR children in general, despite the fact that EMR children had deficits in receptive linguistic competence.     

Evaluation of a French parent-training program in young children with autism spectrum disorder

Parent training programs (PTs) in young children with autism spectrum disorders (ASDs) are known to reduce parenting stress and improve child's behavior and parent-child interactions. Few PTs are available to French speaking families. In order to provide them with this type of intervention, we developed a French parent-training program of 12 bimonthly sessions and three individual home visits based on applied behavior analysis. The purpose of this study is to evaluate the social validity and efficacy of this new PT on eighteen parents who have a child with ASD and developmental delay. For 16 parents, the PT was considered effective, the objectives targeted important and the strategies learned acceptable for use with children. They have significantly improved their knowledge in ASD and behavioral intervention strategies and their children's socialization skills, and reduce their parental stress. This new French PT program seems to be a promising intervention.     

Social acceptance of mentally retarded children in regular schools in relation to years mainstreamed

This study examined whether the social status of mainstreamed retarded children among their nonretarded peers improved as a consequence of extended contact. A sociometric questionnaire was administered to the nonretarded classmates of two groups of retarded children mainstreamed for an average of 1.7 yr. and 4 yr., respectively. Social acceptance of retarded children was low relative to their nonretarded peers. However, in contrast with previous research, retarded children did not receive higher social rejection ratings. Acceptance and rejection measures did not indicate any improvement in social status of the retarded children as a result of an extended period of mainstreaming.     

GENERALIZATION AND TRANSFER BETWEEN COMPREHENSION AND PRODUCTION: A COMPARISON OF RETARDED AND NONRETARDED PERSONS

The study compared the acquisition, generalization, transfer, and maintenance of language comprehension and production responses by persons at two IQ levels: mentally retarded (N = 10) and nonretarded (N = 10). The two levels of the IQ Level factor were combined factorially with two levels of a Training Condition factor: Comprehension-Production and Production Only. Participants in the former groups were trained sequentially to (a) comprehend coin labels by pointing, and then (b) produce verbally the correct coin label. Participants in the Production Only groups were trained on the latter response only. A three-factor mixed design with one repeated measure plus a multiple baseline across coin responses was employed. Results indicated that both mentally retarded and nonretarded subjects attained a high level of acquisition and maintained their performance on 1- and 4-week follow-up tests. No difference occurred between mentally retarded and nonretarded participants in magnitude of acquisition, but the mentally retarded groups took approximately three times as many trials to complete training. Data also suggested, contrary to past research, that generalization from comprehension to production was bidirectional, with no difference in magnitude between mentally retarded and nonretarded subjects. Transfer from comprehension to production occurred in both nonretarded and retarded subjects; comprehension training facilitated a savings of trials in production training. These results show that language differences between retarded and nonretarded persons are quantitative rather than qualitative as some past research may have suggested.     

Comparison of nonretarded and mentally retarded children on tasks involving direct and rule-governed imitation.

The influence of intellectual level and social reinforcement on imitation learning was examined. Tasks involving direct and rule-governed imitation of a mode were presented to 20 mentally retarded and 20 nonretarded children. The children within each group were randomly assigned to either an affective ("good-fine") or an informative ("correct-right") social reinforcement condition. Reinforcement, administered on a fixed ration (FR4) schedule, was contingent on the child's imitative behavior. A multivariate analysis of variance showed that both the Population X Reinforcement Type interaction and the Reinforcement main effect were significant. Univariate follow-up tests showed that only rule-governed imitation contributed significantly to the multivariate effects. Analysis of simple effects indicated that retarded children performed optimally under affective reinforcement, while the nonretarded children performed highest under informative reinforcement.     

Control in memory for movement cues by mentally retarded children

The study was designed to determine the desirability of providing external prompts (1) to use a mnemonic to enhance accuracy of recall and (2) to use response 'priming' in memory for spatial location by mentally retarded persons. Two groups of 40 mentally retarded boys and girls and two groups of 40 MA-matched nonretarded children were compared for accuracy in the recall of movement on an arm-positioning task. No differences were found between mentally retarded subjects and MA-matched subjects treated under the same conditions. However, all groups were unable to make spontaneous control adjustments to accommodate the covert manipulations made just prior to recall. By providing response primes, appropriate performance adjustments were made by all groups, resulting in a significant improvement in accuracy of recall. These findings serve to reaffirm earlier reports showing remarkable similarity between the mentally retarded and MA-matched nonretarded subjects.     

Developmental auditory agnosia in the severely retarded: A further investigation

The hypotheses were investigated that (a) ability to recognize the auditory perceptual stimuli for familiar events is a developmental correlate to language acquisition and (b) the low functioning mentally handicapped suffer from auditory agnosia and are impaired in this ability. The subjects were 42 nonretarded children of ages 3 through 6 and 53 severely and moderately retarded, noninstitutionalized students. The retarded subjects were matched by mental age to the chronological age of the nonretarded children. The stimuli were 49 environmental sounds; the task consisted of sound-and-picture matching-to-sample. Group membership and developmental age were the factors in an analysis of variance design. The results revealed a strong effect of developmental age (p <. 0001). The effect of group was not significant, indicating that auditory agnosia may not be common among the lower functioning retarded. The assumption that agnosia may be a major factor underlying the language disability of the severely retarded was reexamined. It was suggested that the severely retarded achieve the requisite perceptual-semantic knowledge base for language too late, after the critical age for spontaneous and efficient language learning has passed.     

The relationship between father absence and children's social problem solving competencies

Predictions of deficits in children's social problem-solving competencies due to early and continuing father absence were investigated. To test these predictions, equal numbers of father-present and father-absent third graders matched on a number of variables were assessed on measures of social problem-solving performance. In Phase 2 of the study, half of the children from the father-absent category received a 15 week intervention programme which was conducted by adult male trainers to provide structured practice in social problem solving. Results demonstrated that father-absent treatment subjects, compared to father-absent control subjects, improved their social problem-solving skills significantly. Despite improvement due to intervention, social problem-solving scores for father-absent treatment subjects were still below those for father-present control subjects. Educational and developmental implications of the findings were discussed.     

Forgetting in retarded and nonretarded persons under conditions of minimal strategy use

Short-term memory processes of mentally retarded (mild, moderate, and severe) and nonretarded persons were compared in a delayed matching-to-sample task that minimized the use of verbal rehearsal. In addition to trials with delays up to 20 s, the inclusion of trials on which the sample and comparison stimuli occurred simultaneously made it possible to isolate memory and discriminability. Forgetting was most pronounced between the simultaneous and 0-s conditions, and nonretarded subjects forgot less than retarded subjects between these conditions. There were no group differences beyond the 0-s delay. Ease of strategy use failed to account for individual differences, and reported strategy use was not related systematically to performance. These findings are incompatible with the hypothesis that normal-retarded differences occur only on tasks involving effortful cognitive strategies. Differences between nonretarded and retarded groups in this study may be due to a failure in automatic encoding processes in retarded persons.     

Mnemonic strategy instruction in coding, processing, and recall of movement-related cues by mentally retarded children

The purpose of study was to examine the differential coding and processing characteristics of two movement cue types in the investigation of the short-term memory of mentally retarded and nonretarded children. The central focus of the study was to determine the effects of formal instruction in the use of a mnemonic versus no instruction with both types of cues in a memory for movement paradigm. The investigation was conducted across two experiments. The main conclusion drawn from Exp. 1 was that movement 'location' cues were coded, processed, and retained by both the mentally retarded and the nonretarded children, but only the former required instruction in the use of a mnemonic to achieve accurate recall. Exp. 2 was fundamentally a replication of Exp. 1 with the exception that movement 'extent' cues were maintained reliable. The results were similar but not exactly the same as those of Exp. 1. Only the mentally retarded children given mnemonic instruction appeared to code, process, and retain movement 'extent' cues over time. The net result of the two experiments was that formal instruction in the use of a mnemonic was of benefit to the mentally retarded subjects and was not necessary for nonretarded subjects to achieve the same level of movement accuracy.
