Construction of ROC curve. (A) The probabilities for hit (solid line) and false alarm (dashed line) were independently computed at each of the time intervals from 0.0 to 1.2 s with 0.2 s increments following the onset of the response window after the target and reference. The vertical dashed lines indicate the start and the end of the response window. (B) The false-alarm probability function was plotted against hit probability function to construct the ROC curve (solid line). The area under the ROC curve (shaded area) was a measure of discriminative performance of the task.
