Table 1 Paired two-sample t tests comparing unassisted and assisted trials.

Hypothesis testing was performed in R (43) by subtracting the unassisted condition from the assisted condition, showing improvement due to assistance in all five measures. Both the task-specific measures and ergodicity—measured as the distance from ergodicity—capture the effect of the assistance. Note that the df for success rate is 39 because there is only one rate per participant.
