Identification of special education students with mental retardation: Correlates of state child-count data

The number of children identified as mentally retarded by the special education system in the United States has declined dramatically over the past 15 years. Hypotheses regarding this decline have generally focused on changes in state definitions and social factors related to the stigma of the mental retardation classification. In the present study, we investigated differences in state definitions of mental retardation as well as demographic and economic variables as predictors of states' MR identification rates. Definition variables failed to relate significantly to identification rates while several race and per capita expenditure variables were significant predictors. Results are discussed in terms of the importance of investigating demographic and economic variables in understanding the variation in state MR identification rates.     

流动儿童歧视知觉与心理健康水平的关系及其心理机制

为了探讨流动儿童所感受到的歧视对他们心理健康水平的影响, 以及应对方式和自尊在其中所起的作用, 从北京市公立学校和打工子弟学校选取1164名流动儿童、从公立学校选取525名北京儿童、从流动儿童主要来源地的农村选取568名农村儿童作为被试, 采用问卷调查的形式, 测查了流动儿童感受到的歧视、他们的心理健康水平(社交焦虑、孤独感、抑郁)、应对方式和自尊。研究发现: (1) 流动儿童所感受到的社会歧视在学校类型、流动性上存在显著的差异, 打工子弟学校的流动儿童得分显著高于公立学校的, 流动性高的儿童得分显著高于流动性低的, 但在性别上不存在显著差异, 也不存在学校类型与性别和流动性的交互作用; (2) 流动儿童的心理健康水平在性别、学校类型和流动性上存在显著的差异, 女孩、来自公立学校的流动儿童、流动性高的儿童的心理健康水平显著差于与之相对应的被试, 除在社交焦虑和抑郁上存在学校类型和性别的交互作用外, 在孤独感上不存在学校类型和流动性的交互作用; (3) 不同类别儿童在心理健康水平上存在显著差异, 流动儿童在社交焦虑、孤独感上最差; (4) 除消极应对与自尊、积极应对与抑郁相关不显著外, 歧视、心理健康水平、应对方式、自尊两两之间都相关非常显著; (5) 歧视知觉对心理健康水平有显著的直接影响, 也通过应对方式和自尊对心理健康水平产生显著的影响。自尊不仅在歧视知觉与心理健康水平之间起到显著的部分中介作用, 在应对方式和心理健康水平之间也起到了显著的部分中介作用。     

STIMULUS OVERSELECTIVITY IN LEARNING DISABLED CHILDREN

Stimulus overselectivity, a phenomenon exhibited by autistic and institutionalized retarded individuals, was examined in mildly handicapped and nonhandicapped public school children. Subjects were 16 young, educable mentally retarded, 16 learning disabled, 15 nonhandicapped first- and second-graders, and 16 older, educable retarded students. The children were trained on a 3-component visual discrimination task and then tested on individual elements to determine which element or elements were controlling subject responses. Nine of the young educable mentally retarded children and eight of the learning disabled students showed some overselectivity. The majority of overselective retarded children were controlled by only one of the three components of the training cue, whereas the majority of the overselective learning disabled children responded to the discrimination task on the basis of two of the three components. No overselectivity was exhibited by the nonhandicapped students. All three cue components were also functional in controlling the responding of 14 of the 16 older retarded students, but two children were under the control of only one cue. The research indicated that in terms of overselectivity, learning disabled children respond more like young, mildly retarded children than they do like nonhandicapped ones. The demonstration of stimulus overselectivity in a sizable portion of a learning disabled sample may have implications for a more empirically based approach to this handicapped population.

Mentally retarded persons as parents: Prevalence and the situation of their children

This paper describes a research program on mentally retarded parents and their children. For this nation-wide study, two structured questionnaires were sent to all municipalities in Norway. Both questionnaires were sent to public health nurses and were followed-up by a structured telephone interview based on the questionnaires. The primary aim of the study was to survey the number of children born to mentally retarded parents. In addition, the children's needs and functional abilities were to be assessed. Twenty-three mentally retarded persons had given birth in the course of the past twelve months. A total of 126 children with mentally retarded parents were identified, with an incidence of 27 children per year, and a prevalence of approximately 430 children under 16 years of age in a population of 4 mill. People with a mean of 1.05 child per family. About 43% of the children of mentally retarded parents appeared to have learning difficulties. Forty percent of the children suffered from failures of care. Between 25% and 68% of the children with learning problems had poorly developed motor or language abilities, sense modalities or psycho-social status.     

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.     

Differential production of positive and negative discriminative stimuli by normal and retarded children

Using an observing procedure similar to Wyckoff's (1969), two normal and two mentally retarded children were studied. The children were initially trained to earn pennies by pressing a rectangular key according to a multiple variable-interval extinction schedule of reinforcement. After discrimination training, the children were allowed to produce the discriminative stimuli by depressing a second or observing key. The retarded children were different from the normal children in that they produced more of the positive discriminative stimulus (S+) than the negative discriminative stimulus (S?). In the case of the retarded children, S+ observing started high and remained high. In the case of the normal children, S+ observing was initially substantial and then rapidly diminished.     

自闭症幼儿的情感认知特点的实验研究

本实验采用3(组别)×4(基本情绪)×3(实验材料)×2(实验条件)的混合设计的方法对平均心理年龄24个月的6名自闭症幼儿和心理年龄与之相近的6名正常儿童和6名弱智儿童的情感认知特点进行了比较性的研究。实验结果表明:在“语言提示”条件下,自闭症幼儿的正答率远远低于正常儿童和弱智儿童,但在“表情提示”条件下,自闭症幼儿与弱智幼儿几乎没差距,在对“愤怒”和“惊恐”等情绪的认知中,正答率高于弱智幼儿。这意味着自闭症幼儿可能运用了其他的替代策略进行情感认知。     

Evidence for language recoding in autistic, retarded and normal children: a re-examination

In a replication and extension of earlier studies by Hermelin & O'Connor, language recoding abilities in autistic, retarded and normal children matched for mental age and digit span, were compared in a verbal recall task. Random word lists, sentences, and anomalous sentences, eight or 12 items in length (for high and low memory span subgroups) were presented and the number of words recalled from each type of input was scored. All low span children recalled sentences better than random lists with normal children superior to retarded and autistic children and the latter group poorer than the retarded group. Autistic children showed a recency effect with both types of input. There were no group differences amongst high span children and sentences were again better recalled than random lists. In Expt II sentences were better recalled than anomalous sentences, with autistic and retarded children equivalent in performance and poorer than normal children. Although low span autistic children were clearly deficient in recall of sentence material when compared with the two control groups, the effect of conditions showed that they were able to use structure to improve recall. Since high span autistic children did not perform differently from controls it is suggested that results from this kind of study may not be generalizable, and that claims for a specific coding deficit in autistic children need further substantiation.     

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.     

Caregiver interactions with autistic children

Caregiver interactions with young autistic children were contrasted with those involving caregivers and developmentally matched mentally retarded and normal infants. Caregivers of autistic children were similar to other caregivers in their responsiveness to child nonverbal communication bids and in their engagement in mutually sustained play. Caregivers of autistic children were similar to caregivers of mentally retarded children in their greater use of control strategies. However, these two groups of caregivers differed in the particular strategies they used to shape their children's behavior. Caregivers of mentally retarded children pointed to objects while caregivers of autistic children spent more time physically holding their children on task. Individual differences within the autistic sample indicated that caregivers regulated their children's behavior less and showed more mutual play and positive feedback to more communicatively able autistic children. These findings suggest that caregivers respond differentially to the specific deficiencies shown by their children.     

The differential validity of hyperactivity/attention deficits and conduct problems among mentally retarded children

The independence of hyperactivity, attention deficits, and conduct problems among mentally retarded children was addressed using factors of the Conners' Teacher Rating Scale-39 (CTRS-39) and the more recently developed IOWA Conners' inattention/overactivity (IO) and aggression (A) subscales. CTRS-39 ratings were obtained for children of normal intelligence and for mentally retarded children. Differences between the groups were examined as were intercorrelations of the Conners' factors and IOWA subscales. Conduct problems proved to be less strongly associated with hyperactivity and attention deficits among mentally retarded children compared to children of normal intelligence. However, attention problems and conduct problems may be associated with mental retardation in general. Implications of these data and CTRS scoring system recommendations for mentally retarded children are discussed.     

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.     

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.     

Operant measurement of subjective visual acuity in non-verbal children

The present experiment sought to develop a reliable procedure for measuring visual acuity in non-verbal retarded children. Five non-verbal retarded children and two literate adults were examined. The two adults were included in the experiment so that verbal communication with them could validate certain assumptions regarding the experimental procedures. By utilizing a lever press as the criterion response signifying a visual discrimination and employing the Snellen "E" discriminanda, a reliable subjective measure was obtained, not unlike those measures taken from verbal adults. Contrary to several antecedent procedures, a relatively precise measurement of subjective acuity was shown to be obtainable from non-verbal retarded children. Additionally, the procedure was successful in evaluating the effectiveness of prosthetic lenses previously prescribed for two of the children.     

Equivalence class formation in language-able and language-disabled children

Stimulus equivalence seems to have relevance to the study of semantics and of language more generally. If so, there may be a relation between language use and the demonstration of stimulus equivalence. This was examined in three groups of children ranging in chronological age and matched on a conventional measure of mental age: normally developing preschoolers, retarded children who used speech or signs spontaneously and appropriately, and retarded children who did not. All children were taught a series of four related discriminations and were then tested to determine if classes of equivalent stimuli had formed. All of the language-able children (retarded and normal) formed equivalence classes, whereas none of the language-disabled children did so. Although the exact nature of the relation between stimulus equivalence and language remains to be clarified, these results support the view that stimulus equivalence is a phenomenon with relevance to language.     

Parent Perspectives on Child Health and Wellbeing in Same-Sex Families: Heteronormative Conflict and Resilience Building

Measurable aspects of child health and wellbeing for children in same-sex parented families show that these children develop well, overall. Increasingly however, it is understood that stigma can have a negative impact on their health within a same sex family context. The aim of this study is to understand how child health in same-sex parented families is constructed by same-sex attracted parents and what this teaches us about the impact of stigma on child health in this context. Families from across Australia were sampled from a larger study of child health and wellbeing. We used family interviews, which took place between January and August 2013. Thematic analysis was used to identify themes. We report on the data from 11 parents with 10 children. Families presented stories of heteronormative conflict that arose from their position in society. Through family constructs, gender assumptions, discrimination and challenging interactions with institutions this heteronormative conflict had a significant influence on child health, sometimes through the generation of broader familial stress. Resilience building was used by parents to construct a positive environment for child health by combating the lack of understanding and discrimination seen at a societal level. Resilience that is developed to combat stigma provides significant benefits, particularly in a heteronormative world where traditional assumptions about families dominate. The anticipation of stigma, and heteronormative pressures, can stimulate same-sex attracted parents to prepare their children for potential negativity. This should be supported through appropriate school programs and considered political leadership.     

Recognition memory for colors and faces in profoundly retarded young children

Visual recognition memory was examined in a group of profoundly retarded young children whose visual-motor developmental level was estimated to be below one year. The children were tested for recognition of a previously shown face photo or a previously exposed color either immediately or following a short-term delay by observing the distribution of their visual fixation responses to novel stimuli when paired with previously seen targets. During a study or “familiarization” period the profoundly retarded children devoted voted approximately the same amount of attention to photos of faces as they did to colored, abstract patterns, and individual differences in overall looking time proved to be reliable. During the recognition testing phase the profoundly retarded children demonstrated immediate recognition memory for both faces and colors, preferring a novel to a previously exposed target, but responsiveness to novelty declined abruptly over a short-term delay, providing little evidence for delayed recognition.     

The stigma of having a parent with mental illness: Genetic attributions and associative stigma

Children often report associative stigma because they are ‘contaminated’ by association with a parent who has a mental illness. An exploratory study was conducted to investigate the role of genetic attributions in the aetiology of associative stigma. The first hypothesis was that genetic attributions would predict associative stigma over and above the contribution of biochemical and stressful‐event attributions, while the second hypothesis was that the relationship between genetic attributions and associative stigma would be mediated by the perceived likelihood that children would develop the same disorder as their parents. Two‐hundred‐and‐two individuals were asked to read a hypothetical scenario describing a teenage girl whose mother had been diagnosed with either schizophrenia or depression. Both hypotheses were supported. The findings of the study have implications for a number of professions working in the community such as teachers and psychologists. Additional avenues for future research are also explored.
