Psychology Exam Test queries and
answers graded A+
Sensation is _________ as perception is to __________ - ANS✅✅Bottom-up processing; top-down
processing
the process by which we organize and interpret sensory information is called - ANS✅✅perception
Subliminal stimuli are - ANS✅✅below out absolute threshold for conscious awareness
Another term for difference threshold is the - ANS✅✅just noticeable difference
Weber's law states that for a difference to be perceived, two stimuli must differ by - ANS✅✅a
constant minimum percentage
Sensory adaptation helps us focus on - ANS✅✅visual stimuli
Our perceptual set influences what we perceive. This mental tendency reflects out -
ANS✅✅experiences, assumptions, and expectations
The characteristic of light that determines the color we experience such as blue or green is -
ANS✅✅wavelength
The amplitude of light wave determines our perception of - ANS✅✅brightness
The blind spot in your retina is located where - ANS✅✅the optic nerve leave the eye
Cones are the eye's receptor cells that are especially sensitive to ____ light and are responsible for
our ____ vision - ANS✅✅bright;color
Two theories together account for color vision. The Young-Helmholtz trichromatic theory shows that
the eye contains ___ and the opponent-process theory accounts for the nervous system's having
_____ - ANS✅✅three types of color receptors; opponent-process cells
, What mental processes allow you to perceive a lemon as yellow - ANS✅✅Brain constructs the
perception of color in two stages.
-In first stage, the lemon reflects light energy into your eyes, where it is transformed into neural
messages. Three sets of cones, each sensitive to a diff light frequency (red,blue and green) process
color. In this case, the light energy-stimulates both red-sensitive and green-sensitive cones.
-In second stage, opponent-process cells sensitive to paired opposites of color (red/green,
yellow/blue, and black/white) evaluate the incoming neural messages as they pass through your
optic nerve to the thalamus and visual cortex. When the yellow-sensitive opponent-process cells are
stimulated, you identity the lemon as yellow.
The cells in the in the visual cortex that respond to certain lines, edges, and angels are called ____
____ - ANS✅✅feature detectors
The brain's ability to process many aspects of an object or a problem simultaneously is called _____
_____ - ANS✅✅parallel processing
Our tendencies to fill in the gaps and to perceive a pattern as continuous are two different examples
of the organizing principles called - ANS✅✅grouping
In listening to a concert, you attend to the solo instrument and perceive the orchestra as
accompaniment. This illustrates the organizing principle of - ANS✅✅figure-ground
The visual cliff experiments suggest that - ANS✅✅crawling human infants
Depth perception underlies out ability to - ANS✅✅judge distances
Two examples of ______ depth cues are interposition and linear perspective - ANS✅✅monocular
Perceiving a tomato as consistently red, despite lighting shifts is example of - ANS✅✅perceptual
constancy
After surgery to restore vision, patients who had been blind from birth had difficult -
ANS✅✅recognizing objects by sight
