The influence of positive affect and reward on processes of cognitive control
Final Report Abstract
In this project we investigated how performance contingent reward (as compared to positive affect and non-contingent reward) modulates processes of cognitive control. The main findings can be summarized as follows: (1) We found clear evidence that performance contingent reward increases proactive control, even to an extent that it is no longer beneficial. (2) These reward effects are not restricted to mere cue-triggered response priming but also hold true for cue-triggered task rule priming. (3) Performance non-contingent reward - even when provided in runs of 20 consecutive trials - still reduces proactive control and does not generally impair task engagement. (4) Positive affect also appears to reduce proactive control but is very sensitive to strategic influences such as motivation and time on task. The obtained results contribute to our broader theoretical framework, further confirming the selective influence of positive affect and (non) contingent reward on the modulation of the flexibility-stability-balance.
