The four categories selected in the study as conditions, which were derived from the structure of the Go/No-go task and the specific stimuli sequence.

S indicates the actual trial, and S−1 indicates the immediately preceding trial. When S and S−1 require the identical response (executing or withholding), the processing is categorized as ‘Matching’; when S and S−1 require opposite responses, the processing is categorized as ‘Conflicting’. Conditions 1 and 2 split the conflict and match processing in the action execution. Conditions 3 and 4 allow the identical separation in action inhibition.
