  1. Mean and standard deviations for the amount of acceptable, artifact-free epochs are presented for each group by condition. Results of independent-samples t tests are reported for pairwise comparisons between groups. Bold font highlights significant group differences.
  2. Abbreviations: TYP typical development, ASD autism spectrum disorder, NON no known likely gene-disrupting mutation, LGDM likely gene-disrupting mutation
