An absolute threshold is: A. a) the smallest amount of a stimulus that a person can reliably detect. B. b) the maximum amount of a stimulus a person can tolerate. C. c) the amount a stimulus must change for a person to detect a difference. D. d) an amount of a stimulus so small, it is unable to be perceived. E. e) an amount of a stimulus beyond what a person can tolerate.

The correct answer is A. the smallest amount of a stimulus that a person can reliably detect.

Explanation:

An absolute threshold is the smallest amount of a stimulus that a person can reliably detect. Example is in the case of light detection, the smallest level that you are able to detect half of the time is your absolute threshold.

A) The smallest amount of a stimulus that a person can reliably detect

Explanation:

Absolute threshold can be define as the ability of a person to sense or detect stimulus.

Example an individual may be a able to detect stimulus at a lower level.

Absolute threshold can enables someone to detect or sense the difference between when there are stimulus available and when there are non available stimulus .

Absolute threshold is vital because it makes it possible for a person to detect stimulus either through sound , touch, taste and smell which are the human sense which is why it is called ABSOLUTE THRESHOLD.
