Detailed explanation-1: -Absolute threshold: the lowest level at which a stimulus can be detected. Recognition threshold: the level at which a stimulus can not only be detected but also recognized. Differential threshold: the level at which an increase in a detected stimulus can be perceived.
Detailed explanation-2: -The lowest value of a stimulus that produces a perception or sensation.
Detailed explanation-3: -Stimuli below the absolute threshold can still have at least some influence on us, even though we cannot consciously detect them. A variety of research programs have found that subliminal stimuli can influence our judgments and behaviour, at least in the short term (Dijksterhuis, 2010).
Detailed explanation-4: -A difference threshold is the minimum required difference between two stimuli for a person to notice change 50% of the time (and you already know where that “50% of the time” came from).
