Performance summary for Hank (Macaca mulatta). Percentage accuracy is displayed in blocks of 100 trials for both meaningful and nonmeaningful stimuli. The horizontal line at 50% represents chance performance. Performance is similar to and indicative of performance outcomes for all monkeys tested. Subsequently, graphical depictions of the nonsignificant results for all monkeys are not presented. No performance levels on any trial block were significantly different from chance.
