Myers' AP Psychology Sensation and Perception
Exam Questions With Correct Answers
sensation - CORRECT ANSWER✔✔-the process by which our sensory receptors
| | | | | | | | | |
and nervous system receive and represent stimulus energies from our
| | | | | | | | | |
environment.
perception - CORRECT ANSWER✔✔-the process of organizing and interpreting
| | | | | | | | |
sensory information, enabling us to recognize meaningful objects and events.
| | | | | | | | |
bottom-processing - CORRECT ANSWER✔✔-analysis that begins with the sensory
| | | | | | | | |
receptors and works up to the brain's integration of sensory information.
| | | | | | | | | |
top-down processing - CORRECT ANSWER✔✔-information processing guided by
| | | | | | | |
higher-level mental processes, as when we construct perceptions drawing on our
| | | | | | | | | | |
experience and expectations. | |
selective attention - CORRECT ANSWER✔✔-the focusing of conscious awareness
| | | | | | | | |
on a particular stimulus
| | |
inattentional blindness - CORRECT ANSWER✔✔-falling to see visible objects when
| | | | | | | | |
|our attention is directed elsewhere.
| | | |
change blindness - CORRECT ANSWER✔✔-falling to notice changes in the
| | | | | | | | | |
environment.
, transduction - CORRECT ANSWER✔✔-conversion of one form of energy into
| | | | | | | | | |
another. In sensation, the transforming of stimulus energies, such as sights,
| | | | | | | | | | |
sounds, and smells, into neural impulses our brain can interpret.
| | | | | | | | |
absolute threshold - CORRECT ANSWER✔✔-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 fain stimulus (signal) amid background
| | | | | | | | | | | |
stimulation (noise). Assumes that there is no single absolute threshold and that
| | | | | | | | | | | |
detection depends partly on a person's experience, expectations, motivation, and
| | | | | | | | |
alertness.
|
subliminal - CORRECT ANSWER✔✔-below one's absolute threshold for conscious
| | | | | | | | |
awareness
priming - CORRECT ANSWER✔✔-the activation, often unconsciously, of certain
| | | | | | | | |
associations, thus predisposing one's perception, memory or response.
| | | | | | |
difference threshold - CORRECT ANSWER✔✔-the minimum difference between
| | | | | | | |
two stimuli required for detection 50 of the time. We experience this as a just
| | | | | | | | | | | | | | |
noticeable difference (or jnd). | | |
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).
