Sensation/Perception
| Question | Answer |
|---|---|
| Gestalt | An organized hole emphasized our tendency to integrate pieced of information into meaningful wholes |
| Figure-Ground | The organization of the visual field into objects that stand out from their surroundings |
| Grouping | The perceptual tendency to organize stimuli into coherent groups |
| Depth Perception | The ability to see objects in three dimensions although the images that strike the retina are two-dimensional; allows us to judge distance |
| Visual Cliff | A laboratory device for testing depth perception in infants and young animals |
| Binocular Cue | A depth cue, such as retinal disparity, that depends on the use of two eyes |
| Retinal Disparity | A binocular cue for perceiving depth by comparing retinal images from two eyes the brain computes distance |
| Monocular Cue | A depth cue such a as interposition or linear perspective, available to either eye alone |
| Phi Phenomenon | An illusion of movement created when two or more adjacent lights blink on and off in quick succession |
| Perceptual Constancy | Perceiving objects as unchanging even as illumination and retinal images change |
| Color Constancy | Perceiving familiar objects as having consistent color, even if changing illumination alters the wavelengths reflected by the object |
| Perceptual Adaptation | The ability to adjust to changed sensory input, including an artificially displaced or even inverted visual field |
| Frequency | The number of complete wavelengths that pass a point in a given time |
| Pitch | A tones experienced highness or lowness; depends on frequency |
| Middle Ear | The chamber between the eardrum and cochlea containing three tiny bones that concentrate the vibrations of the eardrum on the cochleas oval window |
| Cochlea | A coiled, bony, fluid-filled tube in the inner ear; sound waves traveling through the cochlear fluid trigger nerve impulses |
| Inner Ear | The innermost part of the ear containing the cochlea, semicircular canals, and vestibular sacs |
| Sensorineural Hearing Loss | The most common form of hearing loss, caused by damage to the cochleas receptor cells or the auditory nerve; also called nerve deafness |
| Conduction Hearing Loss | Less common form of hearing loss caused by damage to the mechanical system that conducts sound waves to the cochlea |
| Cochlear Implant | A device for converting sounds into electrical signals and stimulating the auditory nerve through electrodes threaded into the cochlea |
| Place Theory | In hearing, the theory that links the pitch we hear with the place where the cochlea's membrane is stimulated |
| Frequency Theory | In hearing, the theory that the rate of nerve impulses traveling up the auditory nerve matches the frequency of a tone, thus enabling us to sense its pitch |
| Gate-Control Theory | The theory that the spinal cord contains a neurological gate that blocks pain signals or allows them to pass on to the brain |
| Olfaction | Our sense of smell |
| Kinesthesia | Our movement sense-our system for sensing the position and movement of individual body parts |
| Vestibular Sense | Our balance sense; our sense of body movement and position that enables our sense of balance |
| Sensory Interaction | The principle that one sense may influence another, as when the smell of food influences its tatse |
| Embodied Cognition | The influence of bodily sensations, gestures, and other states on cognitive preferences and judgements |
| Audition | The sense or act of hearing |
