Brief report: developing spatial frequency biases for face recognition in autism and Williams Syndrome
Leonard, Hayley C. and Annaz, Dagmara and Karmiloff-Smith, Annette and Johnson, Mark H. (2011) Brief report: developing spatial frequency biases for face recognition in autism and Williams Syndrome. Journal of Autism and Developmental Disorders 41 (7), pp. 968-973. ISSN 0162-3257.
The current study investigated whether contrasting face recognition abilities in autism and Williams syndrome could be explained by different spatial frequency biases over developmental time. Typically-developing children and groups with Williams syndrome and autism were asked to recognise faces in which low, middle and high spatial frequency bands were masked. All three groups demonstrated a gradual specialisation toward the mid-band. However, while the use of high spatial frequencies decreased in control and autism groups over development, the Williams syndrome group did not display a bias toward this band at any point. These data demonstrate that typical outcomes can be achieved through atypical developmental processes, and confirm the importance of cross-syndrome studies in the investigation of developmental disorders.
