Study Notes
Feature Detectors
- Nerve cells in the brain that are responsive to specific features of stimuli, including shape, angle, and movement.
Parallel Processing
- The simultaneous processing of multiple aspects of a problem, a natural brain function for various tasks, especially vision; contrasts with the sequential processing of computers.
Young-Helmholtz Trichromatic Theory
- Proposes the retina contains three color receptors, sensitive to red, green, and blue, which combine to create the perception of any color.
Opponent-Process Theory
- Suggests that color perception is enabled through opposing processes in the retina.
Audition
- The sensory perception related to hearing.
Frequency
- Refers to the number of complete wavelengths that pass a point in a specific timeframe.
Pitch
- The perceived highness or lowness of a tone, determined by the frequency of sound waves.
Middle Ear
- The space between the eardrum and cochlea that houses three tiny bones (hammer, anvil, stirrup) responsible for amplifying eardrum vibrations to the cochlea.
Cochlea
- A coiled, fluid-filled structure in the inner ear where sound waves are transformed into nerve impulses.
Inner Ear
- The deepest part of the ear, containing the cochlea, semicircular canals, and vestibular sacs.
Place Theory
- Links pitch perception to the specific location on the cochlea's membrane where stimulation occurs.
Frequency Theory
- Indicates that the frequency of nerve impulses along the auditory nerve corresponds to the tone's frequency, enabling pitch perception.
Conduction Hearing Loss
- Results from damage to the mechanical system that transmits sound waves to the cochlea.
Sensorineural Hearing Loss
- Caused by damage to the cochlea's receptor cells or auditory nerves, also known as nerve deafness.
Cochlear Implant
- A device that converts sound into electrical signals to stimulate the auditory nerve through electrodes in the cochlea.
Kinesthesis
- Refers to the sensory system that detects the position and movement of body parts.
Vestibular Sense
- Involves awareness of body movement and position, crucial for balance.
Gate-Control Theory
- Proposes that the spinal cord has a neurological "gate" managing pain signals; small nerve fiber activity opens the gate, while larger fibers or brain signals close it.
Sensory Interaction
- The phenomenon where one sense influences another, exemplified by how smell can affect taste perception.
Gestalt
- Represents an organized whole; Gestalt psychology focuses on how we integrate pieces of information into meaningful entities.
Figure-Ground
- The principle of visual organization where we distinguish objects (figures) from their background (ground).
Grouping
- A perceptual tendency to organize stimuli into coherent, easily recognizable groups.
Depth Perception
- The ability to perceive spatial relationships and distance, despite receiving two-dimensional images on the retina.
Visual Cliff
- A research tool used to assess depth perception in infants and young animals.
Binocular Cues
- Depth cues that arise from having two eyes, such as retinal disparity.
Retinal Disparity
- A depth perception cue based on the differences between the images from two retinas; greater disparity indicates closer objects.
Monocular Cues
- Depth perception cues available to one eye, including interposition and linear perspective.
Phi Phenomenon
- The optical illusion of motion created when adjacent lights blink in quick succession.
Perceptual Constancy
- The recognition that objects remain constant in terms of brightness, color, shape, and size, despite changes in illumination and retinal images.
Color Constancy
- The perception of familiar objects as having consistent color, regardless of varying illumination that may change the wavelengths reflected.
Perceptual Adaptation
- The ability to adjust visuals to artificial alterations or displaced visual fields.
Perceptual Set
- A mental predisposition influencing an individual's perception, leading them to favor one interpretation over another.
