This study compared data on sleep disturbances of 22 autistic children obtained by questionnaires with data obtained with actigraphy. Questionnaire responses indicated that autistic children had an earlier morning awakening time and multiple and early night arousals; actigraphic monitoring, however, showed their sleep patterns were normal except…

Criteria to differentiate speaking from nonspeaking autistic preschool children were examined with 10 nonspeaking and 10 speaking children who were followed from age four-and-a-half to late childhood. Total developmental quotient; subscale scores of intellectual, selfcare, and motor ability; and several speech production factors distinguished…

This study of hyperlexia in 80 children with developmental delays found no significant differences in the frequency of hyperlexia in girls compared with boys; a significantly elevated frequency of hyperlexia in children diagnosed with pervasive developmental disorders (PDD) compared with children with non-PDD diagnoses; and a similar range of IQ…

This study of 102 individuals with autism found that the brainstem and cerebellum increased in size with age but were significantly smaller in autistic patients than in controls. Analysis of the speed of development suggests that brainstem and vermian abnormalities in autism were due to an early insult and hypoplasia rather than to progressive…

Three groups of 10 children matched on verbal mental age (either with autism, with Down syndrome, or normally developing) attempted to imitate single pretend acts and a series of pretend acts that formed a script. Although children with autism were best on the single-act imitation, they demonstrated specific difficulties on the script imitation.…

Comparison of children and adolescents with Fragile X Syndrome (n=18) or autism (n=18) for changes in cognitive ability and adaptive behavior over 9 years found steeper decreases in IQ scores among Fragile X subjects with older autistic subjects autism exhibiting stable test-retest scores. Comparative declines in adaptive behavior scores were…

The Psychoeducational Profile was translated into Chinese, adapted, and administered to 23 autistic children and 40 children with normal development, ages 3-7, in Hong Kong. The scale was found to have criterion-related validity, discriminant validity, and properties of a developmental scale. (Author/JDD)

This case study of two young males (ages 3 and 5) with autism who have preoccupations with feminine activities and objects addresses the establishment of gender identity in children with autism and the need for further study of the complex interplay of environmental and neurobiologic factors affecting gender identity and preoccupations in autism.…

In a study by Toshiaki Hashimoto and colleagues (EC 611 142), 10 infants with developmental delay, poor eye contact, and poor facial expression underwent magnetic resonance brain imaging and were later diagnosed with autism. This offered direct evidence of abnormality of the cerebellar vermis and the brainstem at the beginning stages of behavioral…

This study sought to differentiate pervasive developmental disorder not otherwise specified (PDDNOS) from similar nonautistic disorders on the basis of a cognitive deficit, theory of mind (ToM), which is the ability to infer mental states in others, a deficit highly prevalent in autism, a disorder similar to PDDNOS. Results suggest that children…

Seventy-two children (ages 23-148 months) referred to an autism center in the Netherlands were administered the Psychoeducational Profile (PEP) and the Handicaps Behaviour and Skills Schedule (HBS). The correlation between the two instruments was higher than expected, and internal consistency of the subscales of the PEP and the HBS was…

Two studies, 1 longitudinal with 29 subjects and 1 cross-sectional with 132 subjects, examined the adaptive trajectories and profiles of males with mental retardation caused by fragile X syndrome. Significant age-related gains were found in boys ages 1-10 but subjects ages 11-20 showed nonsignificant relations between age and adaptive skills. (DB)

Eighteen cases of disintegrative psychosis (DP) were compared with 52 cases of infantile autism (IA) with speech loss and 145 IA cases without speech loss. DP cases showed clearer regression after more satisfactory development than the IA cases with speech loss, and by age seven were more severely retarded but similar in autistic symptomatology to…

Research on the communication, language, social, and emotional development of people with autism is reviewed, concerning individuals who either are nonspeaking/limited speaking or use speech as their primary mode of linguistic communication. Research needs for longitudinal studies, investigation of early developmental patterns, and subgroup…
