ACTUAL Questions and CORRECT
Answers
Psychophysics - CORRECT ANSWER✔✔- The study of how physical stimuli are translated
into psychological experience.
sensory adaptation - CORRECT ANSWER✔✔- tendency of sensory receptor cells to
become less responsive to a stimulus that is unchanging
bottom-up processing - CORRECT ANSWER✔✔- analysis that begins with the sense
receptors and works up to the brain's integration of sensory information
- register raw stimuli
- convert to neural impulses
- relay to the brain
top-down processing - CORRECT ANSWER✔✔- information processing guided by higher-
level mental processes, as when we construct perceptions drawing on our experience and
expectations
- organizes, identifies and interprets sensation
- form mental representation
Retina - CORRECT ANSWER✔✔- the light-sensitive inner surface of the eye, containing
the receptor rods and cones plus layers of neurons
proximal stimulus - CORRECT ANSWER✔✔- In perception, it is the information our
sensory receptors receive about the object.
distal stimulus - CORRECT ANSWER✔✔- In perception, it is the actual object or event out
there in the world, as opposed to its perceived image.
,proximal stimulus vs distal stimulus - CORRECT ANSWER✔✔- Proximal stimulus is the
stimulation that actually occurs when your sensory receptors are activated... the neural
activity.
Distal stimulus is the actual stimulus or object in the real world that you end up sensing and
then perceiving, which results in the proximal stimulus.
cone cells - CORRECT ANSWER✔✔- work best in bright light and enable you to see
colors; concentrated in fovea
rod cells - CORRECT ANSWER✔✔- work best in dim light and enable you to see black,
white, and shades of gray; concentrated in periphery
just noticeable difference (JND) - CORRECT ANSWER✔✔- the minimal change in a
stimulus that can just barely be detected
Weber's Law - CORRECT ANSWER✔✔- the principle that, to be perceived as different, two
stimuli must differ by a constant minimum percentage (rather than a constant amount); larger
stimulus, larger JND
Area VI - CORRECT ANSWER✔✔- the part of the occipital lobe that contains the primary
visual cortex; activate feature detectors with specialized neutrons that respond to specific
aspects of stimuli (e.g. edges, angles, size) to determine what stimuli is
Neural data --> Thalamus --> PVC (Occipital)
binocular cues - CORRECT ANSWER✔✔- depth cues that depend on the use of two eyes
absolute threshold - CORRECT ANSWER✔✔- the minimum stimulation needed to detect a
particular stimulus 50 percent of the time
signal detection theory - CORRECT ANSWER✔✔- a theory predicting how and when we
detect the presence of a faint stimulus (signal) amid background stimulation (noise).
, perceptual hypothesis - CORRECT ANSWER✔✔- assumptions brain uses to make quick,
automatic extrapolations
Gestalt Principles - CORRECT ANSWER✔✔- ways for the brain to infer missing parts of a
picture when a picture is incomplete; form of top-down processing
monocular cues - CORRECT ANSWER✔✔- depth cues available to either eye alone; help
determine size, distance from motion parallax and pictoral cues
familiar size (monocular cue) - CORRECT ANSWER✔✔- two objects placed higher than
one another look different sizes but are actually the same
linear perspective (monocular cue) - CORRECT ANSWER✔✔- Parallel lines appear to meet
in the distance.
textural gradient - CORRECT ANSWER✔✔- Close objects have greater detail than far
objects.
transduction - CORRECT ANSWER✔✔- The process of converting outside stimuli, such as
light, into neural activity
selective attention - CORRECT ANSWER✔✔- the focusing of conscious awareness on a
particular stimulus
cocktail party effect - CORRECT ANSWER✔✔- Ability to concentrate on one voice
amongst a crowd
