Exam 2

the concentration of mental energy that must be used to process incoming information

active process of focusing on a specific stimulus while ignoring others

attention bottleneck

items that lie outside of our conscious awareness

exposure to a stimulus that influences the processing of a susequent, related stimulus

priming produced by a prior encounter with the stimulus (effortless)

detectors for inputs you think are upcoming are deliberately primed (effortful)

target stimuli is processed faster if preceeded by a related word

target stimuli is processed slower if preceeded by a word related to target's alternative meaning

stand out and grab attention (color, motion, orientation, intensity)

the involuntary focusing of attention, for example by a change in a stimulus which interrupts other processing

decrease in responsiveness when exposed to a repeated stimulus

a change in the stimulus or a new stimulus "resets" the system

failure to perceive unexpected stimulus due to engagement in something else

failure to notice visual stimulus has moved or changed

the brain's ability to focus auditory attention on a single speaker or conversation while filtering out background noises

only attended input is analyzed and perceived, unattended informatino receives little to no analysis

all inputs are analyzed, selection occurs after analysis, unattended information might be perceived but then forgotten
