In a series of studies, researchers examined the visual search of targets that share features with distractors in a visual array and concluded that people with ASD showed enhanced performance on visual search tasks. However, methodological limitations, the small sample sizes, and the lack of developmental analysis have tempered the interpretations of these results. In this study, we specifically addressed age-related changes in visual search. We examined conjunctive visual search in groups of children with (n?=?34) and without ASD (n?=?35) at 7–9 years of age when visual search performance is beginning to improve, and later, at 10–12 years, when performance has improved. The results were consistent with previous developmental findings; 10- to 12-year-old children were significantly faster visual searchers than their 7- to 9-year-old counterparts. However, we found no evidence of enhanced search performance among the children with ASD at either the younger or older ages. More research is needed to understand the development of visual search in both children with and without ASD.

Brief Report: The Autism Spectrum Quotient has Convergent Validity with the Social Responsiveness Scale in a High-Functioning Sample / Kimberly ARMSTRONG in Journal of Autism and Developmental Disorders, 43-9 (September 2013)

It is readily available free of charge online and is easily accessible to practitioners, researchers and individuals who suspect that they may have an ASD. Thus, the AQ is a potentially useful, widely accessible tool for ASD screening. The objective of this study was to examine the convergent validity of the AQ using a well-established, published screening measure of autism: the Social Responsiveness Scale (SRS). Twenty-three high-functioning participants (aged 8–19) with ASD were administered both measures. Results indicated a significant correlation between the SRS and AQ ratings, providing evidence for convergent validity of the AQ with the SRS.

Reliability of self, parental, and researcher measurements of head circumference / Jillian SULLIVAN in Molecular Autism, (January 2014)  

Public ISBD [article]  inMolecular Autism > (January 2014) Titre : Reliability of self, parental, and researcher measurements of head circumference Type de document : Texte imprimé et/ou numérique Auteurs : Jillian SULLIVAN, Auteur ; Teresa TAVASSOLI, Auteur ; Kimberly ARMSTRONG, Auteur ; Simon BARON-COHEN, Auteur ; Ayla HUMPHREY, Auteur Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : The measurement of head circumference (HC) is widely used in clinical and research settings as a proxy of neural growth. Although it could aid data collection, no studies have explored either the reliability of adult self-measurements or parental measurements of young children. This study therefore aimed to examine whether adult self and parental measurement of HC constitute reliable data.FINDINGS:A total of 57 adults (32 male) were asked to measure their HC twice following written instructions (adult self-measurement). These measures were compared to those of a researcher independently measuring the same participant's HC twice. Additionally, mothers of 25 children (17 male) were also asked to measure their child's HC (parental measure), and again this was compared to researcher measurements of the child's HC. The intraclass correlation coefficient between adult self- and researcher measurement was 0.84 and between parent and researcher measurement was 0.99. The technical error of measurement was also acceptable, within the range of a skilled anthropometrist. The high degree of agreement between researcher and adult self-measurement/parental measurement of HC demonstrates that these different assessors produce similarly reliable and reproducible data. This suggests adult self- and parental measurements can reliably be used for data collection to enable valid large-scale developmental and clinical studies of HC.
