The present study isolated and compared ERP components associated with flexible
behavior in two action-control tasks. The ‘withhold’ groups had to withhold all
responses when a signal appeared. The ‘change’ groups had to replace a prepotent go
response with a different response on signal trials. We proposed that the same chain
of processes determined the effectiveness of action control in both tasks. Consistent
with this idea, lateral (Experiment 1) and central (Experiment 2) signal presentation
elicited the same perceptual and response-related components in both tasks with
similar latencies. Thus, completely withholding a response and replacing a response
required a similar chain of processes. Furthermore, latency analyses revealed intraindividual
differences: When the signal occurred in the periphery, differences
between fast and slow change trials arose at early perceptual stages; by contrast,
differences arose at later processing stages when signal detection was easy but
stimulus discrimination and response selection were harder.
