AP PSYCHOLOGY

Detailed explanation-1: -Absolute threshold refers to the minimum amount of stimulus energy that must be present for the stimulus to be detected 50% of the time.

Detailed explanation-2: -Absolute Threshold: the minimum stimulation needed to detect a particular stimulus 50 percent of the time.

Detailed explanation-3: -The difference threshold, or just noticeable difference, is the ability to detect the smallest change in a stimulus about 50% of the time.

Detailed explanation-4: -Absolute threshold: the minimum stimulation needed to detect a particular stimulus 50% of the time. Signal detection theory: predicts how and when we detect the presence of a faint stimulus (signal) amid background stimulation (noise).

Detailed explanation-5: -An absolute threshold is the smallest level of stimulus that can be detected, usually defined as at least half the time. The term is often used in neuroscience and experimental research and can be applied to any stimulus that can be detected by the human senses including sound, touch, taste, sight, and smell.
