2.2.3. Overall and Communicative Development Assessment

Parents filled in the CSBS-DP checklist at the time of the audiovisual and attention tasks, since this tool was also used as a screening tool to make sure that the TD group indeed followed a typical development. Not all infants that participated in the attention and audiovisual tasks provided data for the questionnaire, and thus the sample of infants for overall and communicative development assessment differed from that of the audiovisual/attention tasks (see details in the result section). Data from the CSBS-DP were examined through correlation analyses with performance on the audiovisual task.
