Portage Learning General Psychology
Module 3 UPDATED ACTUAL Exam
Questions and CORRECT Answers
Sensation - CORRECT ANSWER -sense organs converting sensory information to
impulses
Transduction - CORRECT ANSWER -energy from sound or light is converted into nerve
impulse (Action Potential)
sensory adaptation - CORRECT ANSWER -Decreased responsiveness to stimuli after
prolonged exposure
absolute threshold - CORRECT ANSWER -amount of stimulation needed for an organism
to detect it
difference threshold - CORRECT ANSWER -the smallest amount by which two sensory
stimuli can differ in order for an individual to perceive them as different. (AKA: Just Noticeable
Difference)
Weber's Law - CORRECT ANSWER -states that just noticeable difference will be large
when energy is large and small when energy is small
signal detection theory - CORRECT ANSWER -- applied by Green and Swets (1966) to
psychophysics
- useful in furthering understanding in sensation and threshold
a. intensity of stimulus
b. degree of background stimulation (what distractions are present?)
, c. current state of person perceiving the stimulus (groggy or alert?) - CORRECT
ANSWER -What three things does sensation depend on?
Photoreceptors - CORRECT ANSWER -cells at the back of the eye that detect incoming
light
Retina - CORRECT ANSWER -layer at back of the eye formed by photoreceptors
rods and cones - CORRECT ANSWER -What are the two photoreceptors?
cones - CORRECT ANSWER -enable us to see color; concentrated in the center of the
retina called the fovea
rods - CORRECT ANSWER -enables us to see in the dim light
optic nerve - CORRECT ANSWER -bundles of axons from ganglion cells; exits the eye in
our blind spot
ganglion cells - CORRECT ANSWER -third type of cell in retina
Temporal lobe - CORRECT ANSWER -Where do the electric impulses go from
transduction in the ear?
Frequency - CORRECT ANSWER -number of vibrations a sound wave completes in a
given amount of time (How fast is it?)
pitch - CORRECT ANSWER -the highness or lowness of a sound
