5 True/False questions
Perceptual set → the mental process of sorting, identifying, and arranging raw sensory data into meaningful patterns
sensation → The sense of hearing.
difference threshold → Just Noticeable Difference (JND); the smallest change in stimulation that you can detect 50% of the time; differs from one person to the other (and from moment to moment); tells us the flexibility of sensory systems
kinesthesis → The amount of energy in a light or sound wave, which we perceive as brightness or loudness, as determined by the wave's amplitude.
Herman von Helmholtz → A mental predisposition to perceive one thing and not another
