Sensation and Perception (Psychology)

Recall cards on how we sense and perceive the world. Sensation versus perception: sensory receptors and transduction, absolute and difference thresholds, Weber's law, subliminal messages, bottom-up and top-down processing, sensory adaptation, inattentional blindness, and signal detection theory. Waves and wavelengths: amplitude, wavelength, and frequency, the visible spectrum, hue and brightness, pitch, loudness, the decibel, and timbre. Vision: the cornea, pupil, iris, lens, accommodation, retina, rods and cones, the fovea, optic nerve, blind spot, and optic chiasm, the trichromatic and opponent-process theories, afterimages, color blindness, and depth cues (binocular disparity, monocular cues, linear perspective). Hearing: audition, the pinna, eardrum, ossicles, cochlea, basilar membrane, and hair cells, temporal and place theories of pitch, sound localization, and conductive versus sensorineural hearing loss. The other senses: the chemical senses, the five tastes and umami, olfaction, pheromones, touch receptors, thermoception and nociception, and the vestibular sense, proprioception, and kinesthesia. And the Gestalt principles of perception: figure-ground, proximity, similarity, continuity, closure, and perceptual set.
