Background: Autism spectrum disorders (ASD) are characterised by social and communication difficulties in day-to-day life, including problems in recognising emotions. However, experimental investigations of emotion recognition ability in ASD have been equivocal, hampered by small sample sizes, narrow IQ range and over-focus on the visual modality.…

Qiu, Anqi; Adler, Marcy; Crocetti, Deana; Miller, Michael I.; Mostofsky, Stewart H. – Journal of the American Academy of Child & Adolescent Psychiatry, 2010
Objective: Basal ganglia abnormalities have been suggested as contributing to motor, social, and communicative impairments in autism spectrum disorder (ASD). Volumetric analyses offer limited ability to detect localized differences in basal ganglia structure. Our objective was to investigate basal ganglia shape abnormalities and their association…

Schwartz, Lorna T. – ProQuest LLC, 2010
Speech and language pathologists (SLPs) are collaborators in a diagnostic process that reflects an increasing number of referrals of children with autism spectrums disorders (ASD). Also, current practices leading to the remediation of speech and language disorders have come under scrutiny for limitations in effective carryover of targeted goals…

Young, Edna Carter; Diehl, Joshua J.; Morris, Danielle; Hyman, Susan L.; Bennetto, Loisa – Language, Speech, and Hearing Services in Schools, 2005
Purpose: Pragmatic language disorders (PLDs) are difficult to diagnose in a cost-effective manner, and there are few assessment tools that yield quantitative data. This investigation was designed to determine whether two formal assessment tools would differentiate PLDs in children with autism spectrum disorders (ASDs) from controls matched on…
