Background

This script implements Millisecond's version of the 'Pinatatask' (Helfinstein et al, 2013), a child friendly monetary incentive delay task to induce anticipation of reward (and punishment) within a simple reaction time task.

The Inquisit implementation is based on the publicly available eprime script published at: https://osf.io/43hfq/ !!Disclaimer: While we try to stay as faithful as possible to the original eprime script, the Inquisit implementation of the Pinata Task may still differ from it.

This batch script runs a practice script followed by the test script and shares the practice performance category (based on hitrate) automatically with the test script.
