SENSATION AND PERCEPTION FINAL STUDY
GUIDE 2026 TESTED ITEMS SOLVED
◉ Bottom-Up Processing. Answer: Analysis that begins with the
sensory receptors and works up to the brain's integration of sensory
information.
Externally Driven.
◉ Perception. Answer: Selecting, organizing, and interpreting what
comes in your window as meaningful objects and events.
◉ Top-Down Processing. Answer: Guided by higher level mental
processes, such as experience, motivation, and expectations
◉ Perceptual Adaptation. Answer: Ability to adjust to an artificially
displaced field
◉ Psychophysics. Answer: The study of how physical energy relates
to our psychological experience
◉ Transduction. Answer: Conversion of one form of energy into
another
, ◉ Absolute Threshold. Answer: The minimum stimulation needed to
detect a particular stimulus 50% of the time
◉ Difference Threshold
(JND). Answer: The minimum difference a person can detect
between any 2 stimuli 50% of the time
◉ Weber's Law. Answer: Difference thresholds differ by a constant
percentage rather than a constant amount.
◉ Signal Detection Theory. Answer: Predicts when we will detect
weak stimuli amid background noise
Depends on experience, expectations, motivation, and fatigue level
◉ Subliminal Messages. Answer: Stimuli below one's absolute
threshold
Unconsciously sensed
Works to an extent
◉ Sensory Adaptation. Answer: Diminished sensitivity as a
consequence of constant stimulation
◉ Wavelength. Answer: Determines Hue
