Table 3 The first column shows the average duration across all individuals’ successful trials in Experiment 2, measured as the time taken from touching the string for the first time to holding the black token.

  1. Unsuccessful trials where individuals failed to retrieve the rewarding token are not included. The second column contains the pull-step ratios across individuals their successful trials, calculated as the percentage of correct pulls followed by steps (or other string attachments) over all attempts to pull the vertical string.
