Perceptual Thresholds Weber’s Law

Threshold A point in which a stimulus is perceived and below which it is not perceived. The threshold determines when we first become aware of a stimulus.

Absolute Threshold The intensity level of a stimulus such that a person will have a 50% chance of detecting it.

Subliminal stimulus Has an intensity that gives a person less than a 50% chance of detecting the stimulus.

Just noticeable difference (jnd) Refers to the smallest increase or decrease in the intensity of a stimulus that a person is able to detect.

Weber’s law States that the increase in intensity of a stimulus needed to produce a just noticeable difference grows in proportion to the intensity of the initial stimulus.
