Reward positivity affects temporal interval production in a continuous timing task

摘要: The neural circuits of reward processing and interval timing (including the perception and production of temporal intervals) are functionally intertwined, suggesting that it might be possible for momentary reward processing to influence subsequent timing behavior. Previous animal and human studies have mainly focused on the effect of reward on interval perception, whereas its impact on interval production is less clear. In this study, we examined whether feedback, as an example of performance‐contingent reward, biases interval production. We recorded EEG from 20 participants while they engaged in a continuous drumming task with different realistic tempos (1728 trials per participant). Participants received color‐coded feedback after each beat about whether they were correct (on time) or incorrect (early or late). Regression‐based EEG analysis was used to unmix the rapid occurrence of a feedback response …
