Reward Stop Signal Task (RSST)¶
Implemented through extensions systems in the RSST module.
This experiment perform the same task implemented in 1: Background: Inhibitory control, a key modulatory component of cognition guiding strategy and behaviour, can be affected by diverse contingencies. We explore here the effect of expectation of reward over behavioural adjustment in a Stop Signal Task modulated by reward. We hypothesize that cognitive control is modulated by different expectation of the reward.
Methods: Participants were allocated to two groups differing in their degree of knowledge in what to expect from rewards. Expected Specific Reward participants (N = 21) were informed of the different monetary feedbacks they would receive after each successful inhibition. Unexpected Reward participants (N = 24) were only told that they would receive monetary reward after correct inhibitory trials, but not the amounts or differences.
Configuration options¶
Stmuli duration: The time for each stimuli to be displayed. 750 bu default.
Initial delay: The inhibition time for the first trial, this will change according to the subject performance. 500 by default.
