PSYCHOLOGY OF EMOTIONS

Detailed explanation-1: -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-2: -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-3: -But what is that “50% of the time” part of the definition for? Why not 100% of the time? That is because our absolute threshold can vary according to external and internal factors like background noise, expectation, motivation and physical condition.

Detailed explanation-4: -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.

Detailed explanation-5: -Absolute threshold is the smallest level of energy required by an external stimulus to be detectable by the human senses, including vision, hearing, taste, smell and touch. It is more precisely defined as the degree of intensity of a stimulus necessary to correctly detect that stimulus 50% of the time.
