Manifestation of choice in response-locked LRP. A, The average response-locked LRP is shown for correct and incorrect trials for the three payoff conditions. The upward direction is defined to be activity toward the stimulus. A′, The difference between the response-locked LRP of correct and incorrect trials obtained from LRPs shown in A. The differential activity toward stimulus shows that there is no difference between the average lateralization of correct and incorrect trials in all payoff conditions up to ∼200 ms before response. B, Average response-locked LRP is shown for correct and incorrect trials in which the upward activity depicts lateralization toward the final response. B′, The differential activity between correct and incorrect trials as obtained from LRPs in B shows that correct trials on average have a higher LRP amplitude than LRPs of the incorrect trials. This was true across all three conditions.
