Pragmatic Language and School Related Linguistic Abilities in Siblings of Children with Autism

Siblings of probands with autism spectrum disorders are at higher risk for developing the broad autism phenotype (BAP). We compared the linguistic abilities (i.e., pragmatic language, school achievements, and underling reading processes) of 35 school-age siblings of children with autism (SIBS-A) to those of 42 siblings of children with typical development. Results indicated lower pragmatic abilities in a subgroup of SIBS-A identified with BAP related difficulties (SIBS-A-BAP) whereas school achievements and reading processes were intact. Furthermore, among SIBS-A-BAP, significant negative correlations emerged between the severity scores on the Autism Diagnostic Observation Schedule and full and verbal IQ scores. These results are discussed in the context of the developmental trajectories of SIBS-A and in relation to the BAP

Pedantic speaking style differentiates asperger syndrome from high-functioning autism

Asperger syndrome (AS) is a pervasive developmental disorder recently introduced as a new diagnostic category in the ICD-10 and the DSM-IV. Along with motor clumsiness, pedantic speech has been proposed as a clinical feature of AS. However, few attempts have been made to define and measure this symptom. We studied 17 patients with AS (ICD-10; 14 male, 3 female; mean age 16.4 years, mean full-scale IQ 97) and compared them with a control group of 13 patients with normal-intelligence autism or high-functioning autism (HFA) (ICD-10/DSM-III-R; 12 male, 1 female; mean age 15.5 years, mean full-scale IQ 81.2). An operational definition of pedantic speech was formulated and a rating scale devised. 13 (76%) of the AS patients were rated as pedantic compared to 4 (31%) of the HFA group (χ 2 =6.3; p = .01). Results suggest that pedantic speech is common in AS and may help differentiate AS from high-functioning autism .Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/44615/1/10803_2005_Article_BF02172348.pd

The effects of multiple-exemplar self-instructional training on high school students' generalized conversational interactions

A multiple-baseline-across-students design was used to investigate the effects of multiple-exemplar self-instructional training on the acquisition and generalization of conversational interaction of 4 high school students with mental retardation. The multiple-exemplar component of the model consisted of (a) several peers without disabilities teaching the use of a self-instructional social skills strategy across diverse examples of conversational interactions and across two settings and (b) assessing the generalized effects of training across additional peers and one setting. Findings indicated that peers were effective in teaching the multiple-exemplar strategy and that peer training was associated with systematic increases in generalized conversational interactions with familiar and unfamiliar peers with and without disabilities in an additional setting. Social validation data indicated that following multiple-exemplar training, all participants' performances approximated those of general education students and was judged by others to have improved
