Response Inhibition Is Facilitated by a Change to Red Over Green in the Stop Signal Paradigm.

摘要: Actions are informed by the complex interactions of response execution and inhibition networks. These networks integrate sensory information with internal states behavioral goals to produce an appropriate action or update ongoing action. Recent investigations have shown that, behaviorally, attention is captured through a hierarchy colors. studies showed how color affected visual processing. To determine whether can be extended higher level executive functions such as inhibition, we conducted several experiments using stop-signal task (SST). In first experiment, modified classic paradigm so that go signals could vary in task-irrelevant color, auditory stop signal. We found did not differentially affect times. second experiment determined making signal relevant for selection still reaction times and, thus, execution. third was change The mean time red approximately 25ms faster than green other words, facilitated more signals, however, there no comparative facilitation findings suggest but execution, sensitive differences salience. They also based on attentional simply early
