Abstract

The aim in the current study was to investigate the early development of joint attention, eye contact and affect during the first 2 years of life, by using retrospective parental interviews and analyses of home videos of infants who were later diagnosed with Autistic Disorder (AD). The 36 children with AD and the 27 matched control children were all aged between 3 and 5 years at recruitment. Reported anomalies in gaze and affect emerged in the children with AD as early as the first 6 months of life, generally becoming more severe just prior to the second birthday. Video data confirmed these anomalies from as early as the first year. Joint attention impairments were found throughout the second year of life. The results suggest that early dyadic behaviours—eye contact and affect—may play a role in the joint attention impairment in AD.

MANOVAs were used to analyse the data since experiment-wise error rate is appropriately controlled while several dependent variables are being analysed (Hall and Bird 1985). This was considered preferable to the more conservative method of using a Bonferroni adjustment (Keppel 1982) which increases the risk of committing Type 2 errors to an unacceptable level.

A detailed coding protocol is available from the authors; N.B. The Early Social Communication Scales, Seibert et al. (1982) and the ADOS-G Module 1/2 (Lord et al. 1999) were used in the development of these operational definitions.
 
3
Qualitative ratings were not undertaken when there was less than 4 min of video footage as the coder could not confidently make this judgment.
