______ is a mathematical model of what determines a person's report of a near-threshold stimulus.
A) Signal detection theory
B) Response bias theory
C) Weber's law
D) Fechner's threshold

Question

Quizplus · Accepted Answer

Signal detection theory is a mathematical model that explains an individual's ability to detect a signal amidst background noise or ambiguity. It takes into account both the individual's sensitivity to a stimulus (signal) and their response bias (the tendency to respond in a certain way). Therefore, it is the best choice for the given question. Response bias theory only explains an individual's tendency to respond in a certain way, while Weber's law and Fechner's threshold are principles related to the physical attributes of stimuli.
