Participants in the TD control group were selected from a sample of 37 participants (19 male) who performed this task either as part of another study investigating developmental change of the VEP, or as part of the previously published study (Milne et al., 2009). Data from 12 of these participants is presented here; their inclusion was based on being a suitable match to one of the participants with ASD in terms of gender, age, and IQ and generating data from which an independent component that fulfilled the selection criteria (see below) was identified. The two samples of data were therefore well matched both in terms of participant characteristics and data quality. Participant details are provided in Table 1.
