Signal Detection Theory has wide application, both in humans and animals. Topics include memory, stimulus characteristics of schedules of reinforcement, etc. Conceptually, sensitivity refers to how hard or easy it is to detect that a target stimulus is present from background events. For example, in a recognition memory paradigm, having longer to study to-be-remembered words makes it easier to recognize previously seen or heard words. In contra… WebSignal detection theory allows you to compute sensitivity and criteria separately from subject responses (i.e. the hit and false-alarm rates) so that you can determine how …
