WebEvery sense has an absolute threshold. The absolute threshold is defined as the lowest intensity at which a stimulus can be detected (recently, signal detection theory has offered a more nuanced definition of absolute threshold: the lowest intensity at which a stimulus will be specified a certain percentage of the time, often 50%). Websignal detection theory. Looks at how we make decision under conditions of uncertainty - discerning between important stimuli and unimportant "noise". At what point can we …
