Psychosocial adaptation of fathers of children with autism, Down syndrome, and normal development.

Fathers have been largely neglected in previous research of families of autistic children. We compared fathers of 20 autistic, 20 Down syndrome, and 20 developmentally normal children on several measures of psychosocial adaptation. Groups were matched on child's adaptive behavior age equivalent, gender, birth order, family size, and SES. The three groups differed significantly on measures of intrapersonal and family functioning but not on social-ecological variables. Fathers of children with autism or Down syndrome reported more frequent use of wish-fulfilling fantasy and information seeking as coping strategies as well as more financial impact and disruption of family activities than did fathers of developmentally normal children. There were few significant differences between fathers of children with autism and those of children with Down syndrome. These results suggest that fathers adapt relatively well to the demands associated with raising a child with a developmental disability.

Concrete operational thought in children with learning disabilities and children with normal achievement.

This study compared Piagetian cognitive development in normal achieving children and two groups of children with learning disabilities designated as either auditory-linguistic or visual-spatial on the basis of Verbal-Performance IQ differences on the Wechsler Intelligence Scale for Children-Revised (WISC-R; 1974). The two groups with learning disabilities were matched with normal achieving controls on intelligence, socioeconomic status, sex, race, and age. Piagetian tasks measuring conservation, seriation, and classification were administered to each child to determine level of operative thought. The auditory-linguistic group scored significantly below normal controls in operativity, and significantly fewer were at a concrete operational level on a conservation of length task than were normal achieving children. The visual-spatial group did not differ significantly from normal controls. These results suggest that auditory-linguistic disabilities may be more detrimental than visual-spatial disabilities to development of operativity.

A comparative evaluation of adaptive behavior in children and adolescents with autism, Down syndrome, and normal development.

The adaptive behaviors of 20 autistic, 20 Down syndrome, and 20 developmentally normal children were compared using the Vineland Adaptive Behavior Scale. Unlike previous studies, we included a comparison group of very young normally developing children and matched subjects on overall adaptive behavior as well as several pertinent demographic characteristics. Findings revealed that, relative to children with Down syndrome or normal development, autistic children displayed significant and pervasive deficits in the acquisition of adaptive social skills, and greater variability in adaptive skills. These findings underscore the need to longitudinally assess the development of socialization in autistic children and further highlight the utility of the Vineland in operationally defining the nature of social dysfunction in autistic children.

Do autistic children differ from retarded and normal children in Piagetian sensorimotor functioning?

Piagetian sensorimotor functioning of 10 autistic, 10 retarded, and 10 normal children, closely matched on mental age, was assessed with the Dunst revision of the Uzgiris and Hunt scales of infant psychological development. The three groups showed no significant differences in overall performance or specific subtest performance as revealed by estimated developmental ages, number of failed items, and Piagetian stage levels. These findings, which are contrary to previous reports of early sensorimotor deficits specific to autism, suggest that the long-term cognitive deficits in autism are more in symbolic thinking, which does not emerge until the end of the sensorimotor period.

The autistic child and family functioning: a developmental-family systems perspective.

Autism is a severe, long-term developmental disorder that potentially has substantial influence on different aspects of the family system. Principles from family-systems theory are considered as they relate to the autistic child within the family. A selective and critical review is presented of research findings on the influence of the autistic child on the functioning and interactions of family members, including parents, siblings, and the family as a whole. Research findings are also reviewed on resources associated with successful family adaptation to the autistic child. Suggestions are offered for improved research to assess the relationship between certain child variables and measures of family functioning.

Autism and Piaget's theory: are the two compatible?

Autism is interpreted in Piagetian terms with particular reference to the question of whether the atypical cognitive development represents an exception to the similar sequence hypothesis. Findings from relevant research applying Piaget's theory to mental retardation, psychosis, and autism are reviewed. The apparent exceptions to the hypothesis presented in autistic individuals are explained by Piaget's two-factor theory of figurative versus operative functions. Many autistic individuals show an arrest in operative functions at the sensorimotor level while continuing to progress in figurative functions. The early arrest interferes with subsequent development of higher-level conceptual, symbolic, and social skills. Questions for research are offered.
