STUDY GUIDE 2026 QUESTIONS WITH
ANSWERS GRADED A+
◉ What is transduction? Answer: The conversion of stimuli detected by
receptor cells to electrical impulses transported to the brain.
◉ What is perception? Answer: The organization and interpretation of
sensations by the brain.
◉ What is psychophysics? Answer: The branch of psychology that
studies the effects of physical stimuli on sensory perceptions and mental
states.
◉ What is the absolute threshold? Answer: The intensity of a stimulus
that allows an organism to just barely detect it.
◉ What is the absolute threshold for vision? Answer: A single candle
flame burning 30 miles away.
◉ What is the absolute threshold for hearing? Answer: The tick of a
clock 20 feet away in a quiet room.
, ◉ What is the absolute threshold for taste? Answer: 1 teaspoon of sugar
dissolved in 3 gallons of water.
◉ What is the absolute threshold for smell? Answer: 1 drop of perfume
in a three-room apartment.
◉ What is the absolute threshold for touch? Answer: The wing of a bee
dropped on our cheek.
◉ What is signal detection analysis? Answer: A technique used to
determine the perceiver's ability to separate true signals from
background noise.
◉ What are the two measures yielded by signal detection analysis?
Answer: Sensitivity and response bias.
◉ What is the difference threshold? Answer: The change in a stimulus
that can just barely be detected, also known as the just noticeable
difference (JND).
◉ What is Weber's Law? Answer: The JND is a constant proportion of
the original intensity of the stimulus.
◉ What are subliminal stimuli? Answer: Stimuli that fall below the
absolute threshold that may or may not influence behavior.
