- 6ThresholdsAbsolute threshold is the lowest level at which an individual can experience a sensation.
Differential Threshold (Just Noticeable Difference – JND) - Minimal difference that can be detected between two similar stimuli - 7Weber's lawThe JND between two stimuli is not an absolute amount but an amount relative to the intensity of the first stimulus
The stronger the initial stimulus, the greater the additional intensity needed for the second stimulus to be perceived as different. - 8Attention Perceptual selectionPeople attend to only a small portion of the stimuli to which they are exposed
- 9Attention Attention economics:management of information that treats human attention as a scarce commodity, and applies economic theory to solve various information management problems.

- 11How Attention Works: 2 States of AttentionLocation State (Where?): 2 strategies in location state:
Saliency Map (Treisman et al 1980, Wolfe et al 1994)
Systematic Search (Monk 1984, Ponsoda et al 1995)
Identification state (What?): Gather more information of selected object: e.g., reading, holding, etc. - 12Saliency map
- 13Systematic Search

- 15Grouping principle
- 16Figure-ground principle
