Choice and saccadic latency in a concurrent random interval reinforcement program

Abstract

Conventional decision models view reaction time as a consequence of decision-making process and it is classically assumed that the voluntary decision that one can make is where to make a saccade: changes in latency distributions are viewed as an artifact arising from the experimental conditions. However, some studies showed that reaction time distributions may be affected by reinforcement contingencies (Madelain et al., 2007). Here, we probe the possibility of a voluntary control of saccadic latencies in a choice paradigm.
