Top Down Processing
Definition
Use past experiences and othre things to recognize a stimulus
Term
Absolute Threshold
Definition
min. stimulation you need to detect a stimulus more than 50% of the time
Term
Alternative Signal Detection Theory
Definition
looks at ppls biases in response to a stimuli (like will they guess if they hear it or not)
Term
Difference Threshold
Definition
How different do two things need to be before that difference is noticeable and you're guessing better than chance (so minimum change necessary)
Term
cornea
Definition
surrounds the eye and point of entry where light hits the eye
Term
Iris
Definition
colored area that controls the size of the pupil

Lens
Definition
focuses the light to the back of the eye

Definition
short, middle, and long wavelength cone receptors
Term
Young-Hemoltz trichromatic theory
Definition
short, middle, and long wavelength cone receptors
Term
Opponent Processing Theory
Definition
Some colors cause an excitatory response, others cause inhibitory

Term
auditory nerve
Definition
Term
visual cortex

where info from rods and cones goes
Term
auditory cortex
Definition
where info from auditory nerve enters
Term
frequency theory
Definition
freq. of sound correlates with AP produced by hair cells (low sounds)

that level of experience removed from conscious awareness
Term
preconscious level
Definition
info or mental events that are just out of awareness but could easily be brought back to consciousness (ex.zoning out in class)
Term

additive color theory
Definition
all combos of colors caused by mixing of certain colors of light (light emitted from a source)
Term
subtractive color theory
Definition
all colors (esp. for paints and stuff) are caused by what colors the material absorbs or reflects.

Term
insomnia
Definition
treat the UNDERLYING CAUSE
go to bed when sleepy
standardize routine to promote clues to sleep
bright light and social interactions to accentuate wake periods
avoid stimulants
use hot shower in PM

Term
classical conditioning
Definition

Term
extinction
Definition
break assoc bw CS and UCS, which eliminates the CR
Term
Spontaneous recovery
Definition
reemergance of a CR after a CS is reintroduced
Term

Definition
CR occurs not only to the CS, but also to stimuli that resemble the CS
