(A), (B), (C) and (D) are psychometric function plots of Experiment 2. (E) displays the sequential effect index between Experiment 1 and Experiment 2. (A). Response probabilities of “Longer than 1.2 second” on the comparison duration (0.6, 0.8, 1.0, 1.2, 1.4, 1.6 and 1.8 s) separately for previous time reproduction and direction adjustment tasks when the prior duration was either short (including 0.6, 0.8, and 1.0 s) or long (including 1.4, 1.6, and 1.8 s). The lines show the best-fitting psychometric function. (B). Points of subjective equality (PSE) values were plotted for previous time reproduction and direction adjustment tasks when the previous duration was short or long. (C). Response probabilities of “Longer than 1.2 second” on the comparison duration when participants made “Short Response” or “Long Response” in the previous time reproduction trials. The lines show the best-fitting psychometric function. (D). Corresponding PSE values for prior “Short Response” or “Long Response”. (E). Sequential effect index for previous timing trials and direction-reporting trials between Experiment 1 and Experiment 2. Error bars represent ± SEM. **p < .01, *p < .05. n.s. denotes non-significant.
