AP psych unit 3 Questions and
Answers (100% Correct Answers)
Already Graded A+
sensation
Ans: information coming into our brains from our sensory receptors. ex
light waves, sound waves, etc.
perception
© 2026 Assignment
Ans: the process of organizing and interpreting sensory information,
enabling us to recognize meaningful objects and events
Guru01 - Stuvia
transduction
Expert
Ans: transferring physical energy into neural messages that our brain
interprets
wavelength
Ans: The distance between two corresponding parts of a wave
intensity
Ans: the amount of energy in a light or sound wave, which we perceive as
brightness or loudness, as determined by the wave's amplitude
hue
Ans: the dimension of color that is determined by the wavelength of
light; what we know as the color names blue, green, and so forth
pupil
Ans: the adjustable opening in the center of the eye through which light
enters
iris
Ans: muscle that controls the pupil opening and closing
lens
Ans: behind the pupil, changes shape to focus light energy onto the
retina (accomodation)
, 2
retina
Ans: light sensitive inner surface of the eye, contains photoreceptors,
where transduction occurs
accommodation
Ans: lens changing shape depending on the distance of an object
rods
Ans: photoreceptors that percieve black and white, dim light, 120 million
cones
© 2026 Assignment
Ans: photoreceptors that perceive color, fine detail, mostly in the fovea,
6 million
Guru01 - Stuvia
optic nerve
Expert
Ans: nerve that carrier neural impulses from eye to brain
blind spot
Ans: area where optic nerve leave the retina, contains no rods or cones
fovea
Ans: central point of focus on the retina (cones are clustered here)
feature detectors
Ans: nerve cells in the brain that respond to specific features of the
stimulus, such as shape, angle, or movement
parallel processing
Ans: the processing of many aspects of a problem simultaneously; the
brain's natural mode of information processing for many functions,
including vision.
Young-Helmholtz trichromatic theory
Ans: three types of cones in the retina, red, blue, green. These 3 types of
cones can make millions of combinations of colors. In the cones and
retina
opponent process theory
Ans: neurons in retina and thalamus come in pairs, red/green,
