ARCHER PSY 100 - QUIZ 2 CHAPTER 6 2025
QUESTIONS AND ANSWERS.
1. Sensation - correct answer - stimulation of sensory receptors &
transmission of sensory information to CNS
2. Perception - correct answer - process of selecting, organizing, &
interpreting sensory information
3. Transduction - correct answer - converting physical energy
4. Bottom-up processing - correct answer - starts at the sensory receptors
& works up to higher levels of processing
5. Top-down processing - correct answer - constructs perceptions from the
sensory input by drawing on our experience and expectations
6. Psychophysics - correct answer - study of relationship between physical
aspects of stimuli & our psychological experience of them

7. Absolute threshold - correct answer - smallest intensity of a stimulus that
must be present to be detected 50% of time
8. Difference threshold - correct answer - minimum difference in stimulation
that a person can detect 50% of the time
-JND (just noticeable difference)
9. Signal detection theory - correct answer - theory predicting how & when
we detect the presence of a faint stimulus amid background noise
-assumes no absolute threshold
10. Subliminal - correct answer - below one's absolute threshold for
conscious awareness
11. Priming - correct answer - the activation (often unconsciously) of
certain associations, thus predisposing one's perception, memory, or
response
12. Weber's law - correct answer - to be perceived as different, two
stimuli must differ by a constant minimum percentage (rather than a
constant amount)
