•   Just-noticeable-difference (JND), Weber's law
•   Signal-detection theory
•   Subliminal perception
•   Transduction
•   Visual system
•   Structures of the eye and their functions (cornea, iris, pupil, lens, retina, optic nerve)
•   Light sensitivity in rods and cones
•   Photoreceptors
•   Fovea vs. periphery
•   Blind spot
•   Night vision
•   Dark and light adaptation
•   Electromagnetic spectrum
•   Properties of light (wavelength, amplitude)
•   Theories of color vision (trichromatic, opponent process)
•   Color blindness
•   Characteristics of sound waves (frequency, amplitude)
•   Structures of the ear and their functions: (outer ear, pinna, eardrum; middle ear, 3 bones; inner ear, cochlea,
    basilar membrane, hair cells, auditory nerve)
•   Olfactory system: smell receptors and the cortex
•   Gustatory system: tongue and taste receptors
•   Kinesthetic sense
•   Vestibular sense (including semicircular canals)
•   Skin senses: touch, pain
•   Feature analysis and feature detectors
•   Bottom-up vs. top-down processing
•   Gestalt principles of perceptual organization (figure-ground, closure, proximity, similarity, continuity,
    common fate, law of Prägnanz)
•   Depth perception
•   Binocular cues (retinal disparity, convergence)
•   Monocular cues (relative size, interposition, linear perspective, texture gradient, height in plane, relative
•   Perceptual constancies (color, size, shape)
•   Perceptual set, cultural influences
•   Illusions
