Psych 100- PSU Brian Crosby Exam 2. | Exam Revision Questions
And Correct Answers | Graded A+ | 2025 Update |
Absolute Threshold - Answer -Least Energy for correct stimulus to detect 50% of the Time.
Just Noticeable Difference - Answer -Smallest difference between two thing can be detected 50%
of the
time
-difference in two weight
Top-down Processing - Answer -experience/expectations
-listening to your favorite song bc you know how you'll feel
-past experiences
-Perception
Bottom-up Processing - Answer -Making new sense of new material
-hearing a new song for the first time
Perception - Answer -Method which by sensations are interpreted and organized
-two types: Top-Down and Bottom-Up
Sensation - Answer -Activation of receptors in various sense organs- allowing outside stimuli to
become
neural signals in the brain
Habituation Adaptation - Answer -tendency for brain to stop realizing constant unchanging stimuli
-Ex; fans, clock ticking, sounds that will fade
Sensory Adaptation - Answer -sensory receptors less responsive to constant stimuli
-Ex;being cold in a pool goes away after a little while

Iris - Answer -muscle that controls size of pupil
Pupil - Answer -When light enters interior of the eye
Lens - Answer -helps to focus light to the retina
Visual Accommodation - Answer -When the lens change shape to focus in on something
Retina - Answer --Contains photo receptor cells
-light gets covered to electrical impulses
-3 Layers
3 Layers of the Retina - Answer -1) Light passes through ganglion and bipolar cells
2)reaches and stimulates rods and cones
3)Nerve impulses from rods and cones travel alone a nerve pathway to the brain
How does light become a Impulse - Answer -Light
Sensory Impulse
Visual Cortex in occipital lobe
then decisions are made
Dark Adaption - Answer -recovery of the eyes sensitivity to visual stimuli in darkness after
exposure to
light
(Light to Dark)
-Involved with Rods
Light Adaptation - Answer -recovery of the eyes sensitivity to visual stimuli in light after exposure
to
darkness
(Dark to Light)
-happens really quickly within a matter of seconds
