Just noticeable difference

By Ernest Weber

The minimum difference that can be detected between two objects of similar magnitude

Signal detection theory

By Gustav Fechner

Every event of stimuli requires a discrimination between signal and noise

Absolute threshold

The smallest intensity of a stimuli which can be detected across the sense organs 50% of the time

Bottom up processing

This interprets stimuli at face value. Sensory information is interpreted based on sensory input

Interprets stimuli based on prior information or experience. It relates to classical conditioning and Deja by
