The impact of timing the reward on conflict suppression, considering its duration

The paper explores the role of time dimension of effectiveness (immediate vs. cumulative) in the inhibition of conflict-related behaviors induced by rewards. Effectiveness refers to the strength of the association between rewards and task performance. In Study 1, a within-subject design was used, with 2 factors for immediate rewards (high, low) × 2 factors for immediate effectiveness (high, low) × 3 factors for consistency (inconsistent, consistent, neutral). It was found that under conditions of high effectiveness, rewards had a more significant effect on improving reaction speed. However, rewards and their effectiveness did not affect the inhibition of conflict-related behaviors. In Study 2, the same within-subject design was used, but with 2 factors for immediate rewards (high, low) × 2 factors for cumulative effectiveness (high, low) × 3 factors for consistency (inconsistent, consistent, neutral).…
