AP PSYCHOLOGY

Detailed explanation-1: -An absolute threshold is the smallest amount of stimulation needed for a person to detect that stimulus 50% of the time. This can be applied to all our senses: The minimum intensity of light we can see. The lowest volume of a sound we can hear.

Detailed explanation-2: -the minimum amount of stimulation required to trigger a reaction or produce a sensation. Absolute threshold is measured across several trials. It is the lowest or weakest level of stimulation (e.g., the slightest, most indistinct sound) that can be detected on 50% of trials.

Detailed explanation-3: -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.

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: -The “absolute threshold of sensation” refers to the minimum intensity of a stimulus that a person can detect half the time. This threshold is not fixed, but varies from person to person and can be influenced by psychological factors, such as expectations, motivation, and alertness.
