The performance of two screening instruments for Pervasive Developmental Disorders was studied in the total population of participants with mental retardation between 4 and 18 years (n = 1059) in Friesland, a northern province of the Netherlands. Parents completed the Autism Behavior Checklist...

Systematic study of abnormal repetitive behaviors in autism has been lacking despite the diagnostic significance of such behavior. The occurrence of specific topographies of repetitive behaviors as well as their severity was assessed in individuals with mental retardation with and without...
- Network Model of Decreased Context Utilization in Autism Spectrum Disorder. Beversdorf, David Q.; Narayanan, Ananth; Hillier, Ashleigh; Hughes, John D. // Journal of Autism & Developmental Disorders;Jul2007, Vol. 37 Issue 6, p1040
Individuals with autism spectrum disorders (ASD) demonstrate impaired utilization of context, which allows for superior performance on the �false memory� task. We report the application of a simplified parallel distributed processing model of context utilization to the false memory task. For...
- Quantification Judgement in High Functioning Autism: Superior or Different? Gagnon, Louise; Mottron, Laurent; Bherer, Louis; Joanette, Yves // Journal of Autism & Developmental Disorders;Dec2004, Vol. 34 Issue 6, p679
This study examined the hypothesis of superior quantification abilities of persons with high functioning autism (HFA). Fourteen HFA individuals (mean age: 15 years) individually matched with 14 typically developing (TD) participants (gender, chronological age, full-scale IQ) were asked to...
- Atypical Lexical/Semantic Processing in High-Functioning Autism Spectrum Disorders without Early Language Delay. Kamio, Yoko; Robins, Diana; Kelley, Elizabeth; Swainson, Brook; Fein, Deborah // Journal of Autism & Developmental Disorders;Jul2007, Vol. 37 Issue 6, p1116
Although autism is associated with impaired language functions, the nature of semantic processing in high-functioning pervasive developmental disorders (HFPDD) without a history of early language delay has been debated. In this study, we aimed to examine whether the automatic lexical/semantic...
- Review of Adaptive Behavior Studies in Mentally Retarded Persons with Autism/Pervasive Developmental Disorder. Kraijer, Dirk // Journal of Autism & Developmental Disorders;Feb2000, Vol. 30 Issue 1, p39
A review is presented of the investigations carried out concerning the adaptive behavior of persons with the dual disability of mental retardation and autism/PDD. A close correspondence is found between the results obtained by means of a Dutch set of scales, the SRZ, SGZ, and SMZ, and those...
- Commentary: Further Commentary on the Debate Regarding Increase in Autism in California. Earle, Rita S. // Journal of Autism & Developmental Disorders;Feb2004, Vol. 34 Issue 1, p87
The article presents the views of the author regarding increase in autism in California. The California Department of Developmental Services has reported that the proportion of "higher functioning" children among the autism population has substantially increased and is on the rise, with a steady...

Current research suggests that effort indices designed for the detection of malingered neurocognitive functioning do not have adequate sensitivity or specificity for use in cases where malingered mental retardation (MR) is the issue. Therefore, development and validation of reliable, objective...
- A Longitudinal Study of Pretend Play in Autism. Rutherford, M. D.; Young, Gregory S.; Hepburn, Susan J.; Rogers, Sally // Journal of Autism & Developmental Disorders;Jul2007, Vol. 37 Issue 6, p1024
This study describes a longitudinal design (following subjects described in Rutherford & Rogers [2003, Journal of Autism and Developmental Disorder, 33, 289�302]) to test for predictors of pretend play competence in a group of children with autism. We tested the hypothesis that developmental...
