AP PSYCHOLOGY

Detailed explanation-1: -The sensitivity of a given sensory system to the relevant stimuli can be expressed as what has been called an absolute threshold. This refers to the minimum stimulation needed to detect a particular stimulus 50% of the time.

Detailed explanation-2: -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-3: -The absolute threshold is the minimum amount of stimulation required for a person to detect the stimulus 50 percent of the time.

Detailed explanation-4: -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-5: -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.
