Self-concept in educable mentally retarded and emotionally handicapped children

A total of 48 educable mentally retarded (EMR) and emotionally handicapped (EH) children ( \(\overline {CA} \) =137.7 months) were pretested on Coopersmith's Self-Esteem Inventory (SEI), Nowicki-Strickland's Locus of Control Scale for Children (LCSC), and 3 behavioral measures: (1) risk-taking, (2) a chance/skill task, and (3) delay of gratification. One group of 12 children from each population was then exposed to either a self-confident or a control model. After exposure, Ss were given an opportunity to perform successfully on an ambiguous task and answer questions about their success, and were readministered the SEI, LCSC, and 3 behavioral choices. Correlational analyses of pretreatment data revealed significant relationships between defensiveness and LCSC, SEI, and delay of gratification and a near-significant relationship between LCSC and SEI. EMR and EH Ss were both lower on self-esteem than the general population, while EMR Ss were more defensive, more external, and less likely to delay gratification than EH Ss. Both treated groups matched more of the behavioral choices than the control groups, while only treated EH Ss were more likely to attribute their success to internal causes. It was concluded that EMR and EH children differ in self-concept development and that future attempts to modify self-concept should include greater modeling exposure as well as increased opportunity for performance with its resultant feedback.     

A comparison of short-term memory tests as predictors of reading achievement for learning-disabled and educable mentally retarded students

Poor performance' on short-term memory (STM) tasks has been associated with reading difficulties. However, little research has been devoted to delineating the STM tests that best predict this relationship. To gain insight into the relative efficacy of different STM tests to predict reading achievement, nine measures of STM frequently used by school psychologists were examined with a group of learning-disabled (n = 48) and educable mentally retarded (n = 34) students. The factor structure underlying the STM tasks was also investigated. The results indicated that not all of the STM tasks were significant (p < .05) predictors of reading. Stepwise regression analyses indicated that a sentence memory task was the best predictor for the learning-disabled students, whereas a letter sequences task was the best predictor of reading for the educable students. Factor analysis indicated that a language factor (auditory/verbal) and a non-verbal factor (visual/spatial) were the major components underlying performance on the STM measures. These findings were discussed in the context of the prediction of reading as a function of diagnostic group and the task structure of the STM tests.     

Television viewing habits of emotionally disturbed,learning disabled,and mentally retarded children

Two studies were conducted to compare the television viewing habits of handicapped and nonhandicapped children. In Study 1, one group (N = 38) of emotionally disturbed (ED), learning disabled (LD), and educable mentally retarded (EMR) children and two groups of matched controls comprised of nonhandicapped peers were interviewed about their television viewing habits. In Study 2, 42 ED boys and 42 non-ED boys completed a television program diary. The studies found that handicapped children watch more television overall and more aggression-laden programs (i.e., crime dramas and cartoons) than nonhandicapped children. The potential impact of viewing television aggression on the behavior of handicapped children is discussed.     

Enhancing the creative problem-solving skills of educable mentally retarded students

60 educable mentally retarded students from 3 schools in a large urban school system received 9 wk. of instruction from an adaptation of the Productive Thinking Program. Their performance on measures of creative thinking was compared with that of 60 students who received no additional instruction. The conclusions drawn were that (1) special attention to creative thinking training for educable mentally retarded students may be quite effective and results stable over time and (2) the measures of fluency, flexibility, and originality are the most useful in assessing creative thinking for this group.     

Social perspective-taking and adjustment in emotionally disturbed,learning-disabled,and normal children

Preadolescent emotionally disturbed, learning-disabled, and normal boys were compared on social perspective-taking and behavioral measures to examine possible contributions of social cognitive deficits to children's adjustment problems. Antisocial-prosocial and withdrawn-gregarious behavior dimensions were studied through subscales derived from teacher ratings. Results indicated that across all groups, high perspective-taking was associated with significantly less withdrawal than was low perspective-taking; within groups, this finding was significant only for the emotionally disturbed boys. Contrary to theoretical assumptions, antisocial behavior was not significantly related to perspective-taking across the sample. Among emotionally disturbed boys, relatively higher affective perspectivetaking was significantly correlated with higher antisocial behavior. This positive correlation for the emotionally disturbed group was significantly different from the nonsignificant negative correlation between antisocial behavior and perspective-taking among normals. Findings for learning-disabled boys were intermediate. between results for emotionally disturbed and normal boys on both perspectivetaking and behavioral measures, and the learning-disabled group generally did not differ significantly from either other group. Theoretical and clinical implications of the findings are discussed The authors acknowledge the invaluable assistance and cooperation of many teachers and principals in Jefferson County School District in Colorado, especially Ms. Norma Sobesky, coordinator of the program for Significantly Impaired Emotionally and Behaviorally Disturbed Children, and Ms. Beth Young, coordinator of the program for Perceptual and Communicative Disorders.     

Prevalence and correlates of self-reported depressive mood among seriously emotionally disturbed adolescents.

This study examined self-reported depression on the Reynolds Adolescent Depression Scale among 45 seriously emotionally disturbed adolescents. Scores of one-third of the sample exceeded the cut-off score, which indicated the need for further diagnostic study to assess the possible presence of depression. Significant positive correlations included an association with school attendance, a relationship with scores on the Revised Children's Manifest Anxiety Scale, and an association with teachers' ratings on two subscales of the Revised Behavior Problem Checklist. Also, the Depression scale's negative association with the Lie subscale of the Manifest Anxiety Scale is interpreted as indicative of seriously emotionally disturbed adolescents' response style on self-reported measures of depression.     

A validity study of the slosson intelligence test for use with educable mentally retarded students

The validity of the Slosson Intelligence Test (SIT) was investigated with two age groups of EMR children. The Stanford-Binet and WISC served as concurrent validating criteria. The SIT correlated significantly with the Binet although the SIT mean IQ was significantly higher. No significant differences were found between standard deviations or mental ages of the two tests. The SIT correlated significantly with WISC verbal and full scale with no significant differences found between standard deviations. The SIT mean IQ was significantly below that of WISC verbal, performance, and full scale. Implications for school psychologists are given.     

An observational study of emotionally disturbed and learning-disabled children in school settings

It has been alleged that populations of learning-disabled (LD) and emotionally disturbed (ED) children are essentially indistinguishable on important intervention-related symptoms. To examine this claim, a direct observation study of social interactions during class, lunch, and recess settings in two public schools was conducted. Teacher ratings of school behavior were also collected. The results indicated that the ED boys exhibited significantly more nonphysical aggression and noncompliance than the LD boys across settings, and that the LD boys had significantly higher rates of physical and non-physical aggression and immature behavior than the LD girls. The correlations between the observations and teachers' ratings were modest but consistent with previous studies. The results are discussed with regard to their assessment and treatment implications.This study was supported, in part, by a grant from the National Institute of Mental Health (MH30058). The authors wish to acknowledge the assistance of the following individuals: Patricia Grayson, James Fogarty, Merrill Zusmer, James Burke, Elizabeth Mulvihill, and the teachers from the Sayville and Premm Learning Centers (L. Fass, J. Gould, K. Jones, C. Lacey, B. Licking, S. Ott, S. Palmer, J. Thorpe, C. Wangenstein, D. Wayne, and L. Wetter). We also wish to thank Michael H. Epstein and Jan Loney for their helpful comments on an earlier draft of this paper.     

Social problem solving and mother-child interactions of educable mentally retarded children

Mothers of retarded children and nonretarded children were observed and videotaped as they interacted with their own child in a seminaturalistic situation, requiring teaching, cooperation, and free play. The child's social problem-solving abilities were assessed independently. The Vineland scale was employed to provide some convergent evidence of social problem-solving as a component of social competence. Twelve educable mentally retarded and 19 nonretarded 10-year-old children and their mothers comprised the sample. For the mentally retarded group, it was found that the higher maternal directiveness, the lower the child's social problem-solving skills. Mothers who often gave the child opportunity for decision-making and social influence had children with higher problem-solving skills. The retarded children produced significantly fewer different strategies for solving social problems, but gave a wider range of strategies than has been found in previous research. There was some support that social problem-solving skills are related to social maturity.     

The sufficient conditions for directed forgetting in normal and educable mentally retarded adolescents

A series of studies investigated the conditions under which normal and educable mentally retarded adolescents (13 to 15 years old) would or would not disregard irrelevant information in memory. A directed forgetting task was used in which the person was required to recall short sequences of picture names. In some sequences there was a cue to forget the first few pictures (irrelevant information) and to remember only the subsequent pictures (relevant information). When normal adolescents were given no explanation of the forget cue, there was interference from the irrelevant information. A minimum explanation of the cue, however, was sufficient to eliminate interference for the normal adolescents. The same minimal explanation was not sufficient for mentally retarded adolescents. It was clear that irrelevant information in memory interfered with the performance of retarded adolescents given only a minimal explanation of the forget cue. These results are important since most naturalistic situations do not involve an elaborate explanation of the importance of disregarding irrelevant information previously stored in memory.     

Perceptual learning by educable mentally retarded, average, and gifted children of primary school age

A match-to-sample task and a preference-ranking procedure were used to provide predifferentiation experiences on a color discrimination for 6- and 8-yr.-old children. The subjects included an educable mentally retarded 8-yr.-old group, an average 8-yr.-old group, a gifted 6-yr.-old group, and an average 6-yr.-old group. Mental age was the best predictor of success on task. A significant interaction of sex and teaching method suggests an advantage of girls in this group in instructional situations in which the perceptual learning task and testing tasks are not exactly the same. Girls did better than boys when a different response for task content was required in testing from that in teaching. Boys and girls performed similarly when the training task was the same as the testing task.     

Negative air ionization improves memory and attention in learning-disabled and mentally retarded children

The effect of increased concentrations of ambient negative air ions on incidental visual memory for words and purposive auditory memory for dichotic digits was investigated in 20 normal grade 4 children, 8 learning-disabled children, and 8 mildly mentally retarded children. Half in each group were assigned randomly to an unmodified air-placebo condition under double-blind testing procedures. All of the children breathing negatively ionized air were superior in incidental memory. In dichotic listening, the negative ions produced a counter-priming effect in the two learning-impaired groups, offsetting the difficulties that they showed under placebo in switching attention selectively from one ear to the other. The action of negative ions on the neurotransmitter, serotonin, may be the mechanism by which negative ions produce such behavioral effects. In view of the important environmental and remedial implications of these novel findings, interpretations should be made cautiously pending larger scale replications.This research was supported by a grant from the Ontario Institute for Studies in Education. We wish to thank Paul Hunnisett, who was the first person to our knowledge to suggest that negative ions may have an effect on children's behavior. We also thank Dave Patterson, superintendent of Special Services with the Northumberland and Newcastle Board of Education, for supporting this study, and Muriel Fung, OISE, for assistance with the data analysis.     

Varying preschool arrangements and self-concepts of educable mentally retarded children in grade 1

Differences in measured self-concept among educable mentally retarded children in Grade 1 were examined. Subjects included 90 children randomly selected from larger populations with varying preschool experiences. An initial positive influence of preschool experience on self-concept in Grade 1 appeared to be more pronounced among those subjects exposed to nonhandicapped peers.     

Maintenance and generalization of a semantic rehearsal strategy in educable mentally retarded children

Two groups of 11- to 12-year-old educable mentally retarded children, equated on the basis of a free recall pretest, were given a series of lists for free recall. Approximately half the subjects were trained in the use of a strategy designed to induce deeper level semantic encoding and the discovery of categorical relationships and half constituted a “no-training” control group with standard free recall instructions. The subjects received either related or unrelated lists during the training phase and related or unrelated lists during two post-tests, immediately following and 1 week after training. There was evidence not only that the semantic strategy was maintained over the 1-week delay, but that it also generalized to word lists unlike those used during training. The degree of generalization was greater for those subjects receiving related lists during training.
