Results of Experiment 1. (A). Response probabilities of "Longer than 1 second" on the comparison duration (0.4, 0.6, 0.8, 1.2, 1.4, and 1.6 s) separately for previous task types (Time or Direction) when the prior duration was either short (including 0.4, 0.6, and 0.8 s) or long (including 1.2, 1.4, and 1.6 s). The lines show the best-fitting psychometric function. (B). Points of subjective equality (PSE) values were plotted for previous time discrimination and direction adjustment trials when the previous duration was short or long. (C). Response probabilities of "Longer than 1 second" on the comparison duration when participants made "Short Response" or "Long Response" in the previous time discrimination trials. The lines show the best-fitting psychometric function. (D). Corresponding PSE values for prior "Short Response" and "Long Response". Error bars represent ± SEM. **p < .01, *p < .05.
