Figure 2: Reaction Time and Task Performance. (A) Distribution of mean RT (left) and RT standard deviation (STD)(right) for each participant from trials included in ERP waveforms following all trial rejection procedures. Distributions are plotted separately for the TD group (blue) and the ASD group (red). Dots represent individual participant values. (B) Mean RT for trials included in ERP waveforms stratified as a function of the preceding cue type. (C) Mean RT for trials included in ERP waveforms plotted as a function of age. Blue dots indicate TD participants, and red dots indicate ASD participants. (D) Mean RT across all trials included in ERP waveforms stratified by RT bin. (E) Mean RT across all trials, including trials removed from ERP data analysis, excessively long trials, and excessively short trials. In cases where one trial elicited two or more button press responses, reaction time was computed based on the first response. (F) Percentage of ‘hit’ trials, defined as trials in which the participant responded between 150 ms and 1 second post-stimulus onset. (G) Percentage of trials in which participants responded with more than one button press.
