Proportions of “longer” or “more pitch change” responses as a function of Comparison Level for the time-change (top) and pitch-change (bottom) tasks, and shown separately for the three standard velocity conditions.

Overall, duration tended to be overestimated when the comparison velocity was faster than the standard velocity, and underestimated when the comparison was slower than the standard. On the other hand, pitch change was underestimated when the comparison was relatively fast and overestimated when the comparison was relatively slow. Notably, results were opposite for the time-change and pitch-change tasks.
