Signal detection theory ap psychology.

Signal detection theory predicts when an individual will decide if a weak stimulus is present or not based on psychological factors as opposed to the biological theories of absolute threshold. Psychologists use signal detection theory to evaluate how accurately participants are able toAccording to the theory, there are a number of determiners of how a detecting system will detect a signal, and where its threshold levels will be.

The general approach of signal detection theory has direct application for us in terms of sensory experiments. The subject's task is to detect a signal which is presented along some sensory continuum.

Signal detection theory (SDT) is widely accepted by psychologists; the Social Sciences Citation Indexcites over 2,000 references to an influential book by Green and Swets (1966) that describes SDT and its application to psychology. Even so, fewer than half of the studies to which SDT is applicable actually make use of the theory (Stanislaw
