Research into absolute thresholds has found that
A) there is a fixed point where the probability of detecting a stimulus jumps from 0% to 100%.
B) absolute thresholds vary between 25% detection rates and 75% detection rates, depending on the individual.
C) there are significant cross-cultural differences in absolute thresholds for light and sound.
D) the chances of detecting a stimulus increase as the stimulus intensity increases.

Question

Quizplus · Accepted Answer

Research into absolute thresholds has consistently found that the chances of detecting a stimulus increase as the stimulus intensity increases, which is known as the Weber-Fechner Law. Option A is incorrect because there is no fixed point at which detection probability jumps from 0% to 100%. Option B is also incorrect because absolute thresholds can vary widely between individuals and stimuli. Option C is partially incorrect because while there are some cross-cultural differences, they are relatively minor compared to individual differences.
