The relationship between affective and cognitive development in Down's Syndrome infants.

A close association between affective expression and cognitive development was demonstrated in a longitudinal study of 14 Down's syndrome infants. It was found that the Down's syndrome infants laughed to groups of stimulus items in the same order as did previous samples of normal infants. Although the process was delayed by several months, the retarded babies too laughed first at physically intrusive items and only later to items calling for greater cognitive sophistication. In addition, cognitive developmental status, assessed by the Bayley and Uzgiris-Hunt scales, paralleled and was predicted by the level of affective development. Predictive and concurrent correlations between Bayley mental scores and various indices of affectivity ranged from .68 to .92. There was striking individual consistency across affective, mental, and motor measures, suggesting the organized nature of retarded development. Finally, since Down's syndrome infants frequently smiled under conditions when normal babies would laugh, a role for tension production, in addition to cognitive factors, was suggested in accounting for the behavior of these infants.     

A study of auditory preferences in nonhandicapped infants and infants with Down's syndrome

11 infants with Down's syndrome (MA 9.2 months, CA 12.7 months) and 10 of 11 nonhandicapped infants (MA 9.6 months, CA 9.3 months) demonstrated that they could operate an automated device which enabled them to choose to listen to 1 of a pair of auditory signals. All subjects showed preferential responding. Both groups of infants showed a significant preference for nursery rhymes sung by a female voice rather than played on musical instruments. The infants with Down's syndrome had much longer response durations for the more complex auditory stimuli. The apparatus provides a useful technique for studying language development in both normal and abnormal populations.     

Children's eyewitness memory for a repeated event

OBJECTIVE: This study examined a significant issue for chronic sexual abuse investigations: Children's eyewitness testimony about repeated events. The few previous studies focused on preschoolers and none used the present methodology of presenting repeated events differing slightly in their details, as would happen in chronic abuse. METHOD: One group of 6- to 7-year-olds played individually with an experimenter on one occasion; the other group experienced three such events, with some details remaining the same and others changing. In a phased interview, children were questioned about the initial event. RESULTS: For details which stayed the same, the children who experienced three events had more accurate memories. They had poorer memories than the single-event group for details which were changed in the later events; however, this was due to interference errors, with errors of omission and commission being lower than in the single-event group. Children conveyed clearly that inappropriate touching did not occur. CONCLUSIONS: Children who experience repeated events have increased recall for repeated details but confuse the timing of details which change across events. The findings support previous suggestions that (a) it is unrealistic to expect children to be able to report repeated events without some confusion about timing of details and (b) children are resistant to misleading questions about abuse.     

Mirrow reactions of Down's syndrome infants and toddlers: cognitive underpinnings of self-recognition.

To examine the developmental significance of mirrow self-recognition in early childhood, a cross-sectional study with 55 Down's syndrome children was conducted. When their image is altered by rouge on the nose, normal infants by 22 months indicate self-recognition by touching their noses while looking in the mirror. Only a small percentage of Down's syndrome children touched their noses by this age, confirming the expected lag in this development. However, those young Down's syndrome infants with near-normal development quotient did manifest the reaction. In general, when developmental age was equated, the Down's syndrome children showed parallel development to normal children.     

Complementary expertise in a zoo educator professional development event contributes to the construction of understandings of affective transformation

Cultural Historical Activity Theory served as the analytical framework for the study of a professional development event for a zoo’s education department, specifically designed to build understandings of “Affective Transformation,” an element pertinent to the organization’s strategic plan. Three key products—an Affective Transformation model, scaffolding schematic, and definition, “providing emotional experiences for visitors which increase caring for animals and nature that may lead to zoo-related nature-protective behaviors”—emerged as a result of ongoing deliberation among professional development community members over two days. Participants, including both management- and non-management-level staff, as well as an expert facilitator, contributed complementary expertise to the process. The discussions, therefore, crossed both vertical and horizontal layers of authority. Moreover, leadership was distributed across these levels in the development of these products. Members used pre-existing resources, as well as tools created in the course of the professional development event. Interactions among participants and resources were instrumental in Affective Transformation product development. Examination of one zoo’s construction of understanding of affective goals, therefore, may offer insights to other organizations with similar aspirations.     

The relationship between affective response to social comparison and academic performance in high school

The goal of the present study was to study the relationship between affective responses to social comparison and test scores among high school students. Our analyses showed that three types of responses to social comparison could be distinguished: an empathic, constructive, and destructive response. Whereas girls scored higher on empathic response, boys scored higher on destructive response. In addition, students who had a high social comparison orientation (SCO) scored higher on all three types of responses than students who expressed a low SCO. Multilevel regression analyses indicated that, after controlling for previous performance, a destructive response was negatively related to performance on tests for reading comprehension and mathematics. An empathic response was positively related to performance on reading comprehension only whereas a constructive response compensated the negative relationship between destructive response and reading comprehension. Theoretical and practical implications are discussed.

Pretend play and patterns of cognition in Down's syndrome children

This study was designed to examine the relationship between cognitive functioning of Down's syndrome subjects as measured by the Bayley Scales of Infant Development and their symbolic play level. Subjects ranged in chronological age from 20 to 53 months and in mental age from 12 to 26 months. Each child was seen at home with the mother or primary caretaker present. A 1/2-hour play session was videotaped, followed by administration of the Bayley Mental Scale and Infant Behavior Record. Analysis of play behavior supported a 4-level scale. Symbolic play level was more highly correlated with mental age than with chronological age. Performance on the Infant Behavior Record was also highly correlated with symbolic play level.     

Exceptional educators: a collaborative training partnership for the inclusion of students with Down's syndrome

This article discusses the results of a teacher training initiative in the United States. Exceptional Educators is the result of an inter‐organisational collaboration between a community‐based organisation (Gold Coast Down Syndrome Organization), the local public school system and a university professor. The training focuses on three distinct objectives; understanding the physical and emotional needs of the disability, creating modified curriculum units based on individual learning goals and recognising common behavioral problems that arise in school settings. Overall, the results showed positive outcomes, with gains in knowledge of curriculum modification, behavioural strategies and overall understanding of Down's syndrome, as well as an increase in confidence level. A six‐week follow‐up survey indicated that the majority of the participants used the information presented back in their teaching environments. This study also investigated the added value of this collaboration, finding that the community connection often continues past the training and has provided teachers additional avenues for support.     

The Turner syndrome: cognitive deficits, affective discrimination, and behavior problems

Individuals with sex chromosomal anomalies are known to be at increased risk for learning problems and in some cases social or behavioral problems. Girls with an absent or structurally abnormal second sex chromosome (the Turner syndrome) have been found to have cognitive problem solving deficits and immature, inadequate social relationships. The present study attempted to link cognitive and social problems by assessing the girls' ability to process affective cues. 17 girls with karyotypes consistent with a diagnosis of Turner syndrome were compared to a group of 16 short-stature girls of comparable age, verbal intelligence scores, height, and family socioeconomic status on the Affective Discrimination Task, which required interpretation of affective intention from facial expression. The results revealed that the Turner syndrome girls were less accurate at inferring facial affect than the short-stature controls. Analyses revealed that the Turner syndrome girls performed more poorly on spatial, attentional, and short-term memory cognitive tasks and had more psychosocial problems than the short-stature controls. Ability to discriminate facial affect may be another area of cognitive weakness for girls with the Turner syndrome and may underlie the psychosocial problems found in this sample.     

Education of infants with down syndrome

The early education of infants with Down syndrome has been strongly influenced by studies highlighting the importance of the environment. These studies encouraged the belief that intelligence is not fixed and that early experience is critical to the course of development. Since the origins of a decline in IQ for Down syndrome had been traced to early infancy, it was hoped that early intervention programs might halt or even reverse this decline. The de-institutionalization movement converged with these studies to emphasize the home as a teaching environment and to view the mother as a teacher. It is suggested that the concept of the environment should expand beyond the family and that professionals should consider their own role in terms of the social ecology of the family. The programs need also to address the specific arousal needs of the infant with Down syndrome and to include motivational aspects in addition to cognitive measures when evaluating the effects of infant education.     

Factors associated with the effective inclusion of primary-aged pupils with Down's syndrome

It is increasingly common for pupils with Down's syndrome to be offered places in mainstream primary schools. However, there is still much to learn about the impact of these placements upon children and classrooms. Recently the Nuffield Foundation funded a two-year research project exploring the inclusion of primary-aged pupils with Down's syndrome. The research focused on the inclusion of 18 pupils with Down's syndrome who attended mainstream primary schools in six local education authorities (LEAs) in the north-west of England. The research team investigated the ways in which schools manage the inclusion of pupils with Down's syndrome and the factors that contribute to the success of mainstream placements. In this article, Sam Fox, Peter Farrell and Pauline Davis from the University of Manchester discuss some of the findings from the study. These concern the support in place for the child and the attitudes of staff, other pupils and the parents of peers towards the inclusion of the child with Down's syndrome. Evidence from the 18 case studies suggests that there is no single way to guarantee effective inclusion. The extent to which a child is effectively included in a mainstream class is likely to be influenced by a number of key factors, including the way in which the teaching assistant (TA) works with the class teacher. Inclusion is more likely to be successful when the class teacher takes a central role in the management of support and the organisation of a child's daily educational experiences.     

The organization of exploratory behavior in Down syndrome and nondelayed infants

The exploratory behaviors of a sample of 11 infants with Down syndrome and 11 nondelayed infants, matched on Bayley mental raw scores and gender, were analyzed. Transitional probabilities and z scores were computed for each possible behavior change as well as frequencies of each behavior. The analyses revealed significant differences in how the 2 samples distribute their exploratory activities. The significant transitional probabilities among the 6 behavioral states revealed a pattern of similarities and differences. In general, both groups of infants organized their exploratory activities in a similar manner. However, there were differences that appeared to depend on the level of exploratory sophistication. The results are discussed in the context of the similarities and differences between the samples.     

Predicting parents' satisfaction with the education of their child with Down's syndrome

This study investigated parents' satisfaction with the schooling of their children with Down's syndrome and its relationship to parent identity. Responses to a postal questionnaire from 131 parents of children with Down's syndrome aged from 4 to 19 years were recorded for analysis. Using identity process theory to provide a theoretical framework, it was predicted that parent satisfaction with education would be a function of the extent to which the identity principles described by this theory are threatened by perceived educational circumstances. Composite measures of identity, perceived school climate and parents' satisfaction with school were obtained, and correlations among these variables calculated. Regression analysis confirmed the prediction that parents' satisfaction is closely related to self-efficacy, perceived involvement with their children's education and perceived school climate.
