Over repeated trials subjects are required to decide whether there was a tone present or not. WebAnother study examined the effects of noise on the simultaneous performance of a tracking task and a detection task. For the tracking task, a higher percentage of time spent on target indicated better performance. For the detection task, performance was expressed as the percentage of signals detected in a variety of positions in the visual field.

WebSignal Detection: Hits and False Alarms Examples. If we wish to compare memory ability for two people, why can’t we simply use the percent correct on identifying old items (i.e., hit rate) as the measure of ability?
