Data has been obtained during a computerized motor reaction time: a STOP SIGNAL TASK modified with reward levels. Task consisted on 4 blocks, 4 minutes each. Specific feedback was given inside each block. Three type of feedback were granted: a no monetary feedback given by a Smiley, and two types of monetary rewards: low and high reward. There are two conditions: increasing and decreasing rewards (IC and DC). Both conditions started by a no monetary reward on the first block (Smiley). Increasing conditions conferred a low reward on the 2nd and the 3th blocks and a high reward at the end. Decreasing conditions granted the high reward on blocks 2 and 3, and the low reward at the end. Two groups has been tested: In one group, participants knew about reward levels, the other was blind. Data has been organized through columns in their correspondent reaction time (MRT, SSD, SSRT) and behavioural measures variables (failed inhibition, missed go, wrong keys, rewards). Subjects are identified by letters in order to protect identity of all participants. Special variables has been created to distinguish distinct subgroups and conditions inside the task.
