below one's absolute threshold for concious awareness
- the--often unconcious--activation of of certain associations, thus predisposing one's perception, memory, or response.
- kittens versus werewolves (preference?)
the minimum difference between 2 stimuli required for detection 50% of the time.
the principle that. to be perciv3ed as different, 2 stimuli must differ from a constant minimum of 10%
diminished sensitivity as a consequence of constant stimulation.
- also know as cocktail party effect
- the ablity to truely focus on only one particular stimulus
the failure to see what you're not focused on
