 Formulas used to isolate antisaccade and task switching error and latency costs

ConditionTask
PSAS
Repeated prosaccades (PSR) are the baseline because they require neither an antisaccade nor a task switch. To isolate the antisaccade cost, the baseline was subtracted from repeated antisaccades. To isolate task switching costs, the baseline was subtracted from switched prosaccades. To isolate the task switching cost specifically for antisaccades, repeated antisaccades were subtracted from switched antisaccades.
Antisaccade cost: ASR − PSR
Task switch cost for PS: PSS − PSR
Task switch cost for AS: ASS − ASR
ASS, switched antisaccade; ASR, repeated antisaccade; PSR, repeated prosaccade; PSS, switched prosaccade.
