Abstractionprototype Theory


ABX MODEL/PARADIGM. An experimental method used in the area of psychophysics for determining an organism's sensory difference threshold (i.e, the smallest detectable change in a stimulus or difference between two stimuli that can be detected reliably; also, called discrimination threshold, difference limen, or just noticeable difference, jnd) by presenting two stimuli, A and B, and a third stimulus, X, that is identical to one of the others. The individual's task is to decide whether stimulus X matches stimulus A or B. Another sensory threshold method employed in psy-chophysics, called the absolute threshold (also called the absolute limen or reiz limen) refers to the smallest intensity of a stimulus that can be detected or that reliably produces a sensation in the organism.
