AP PSYCHOLOGY

Detailed explanation-1: -The absolute threshold is the minimum amount of stimulation required for a person to detect the stimulus 50 percent of the time. The difference threshold is the smallest difference in stimulation that can be detected 50 percent of the time.

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: -Absolute threshold refers to the minimum amount of stimulus energy that must be present for the stimulus to be detected 50% of the time. Another way to think about this is by asking how dim can a light be or how soft can a sound be and still be detected half of the time.

Detailed explanation-4: -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.

Detailed explanation-5: -The just noticeable difference (JND), also known as the difference threshold, is the minimum level of stimulation that a person can detect 50% of the time.
