Unit 5 Vocab Flashcards
A monocular cue in which closer objects block farther ones.
Interposition / Occlusion
There are three color receptors (red, green, blue).
Trichromatic Theory
The height of a wave.
Amplitude
Gestalt concept. Distinguishing objects from background.
Figure and Ground
Focusing on one voice in a crowd.
Cocktail Party Effect
Missing changes in the environment when vision is interrupted.
Change Blindness
Sense of taste.
Gustation
Inner ear canals used for balance.
Semicircular Canals
Clearer vision for nearby objects.
Nearsightedness
Missing visible objects when focused elsewhere.
Inattentional Blindness
Focusing on a particular stimulus.
Selective Attention
Responding to visual stimuli without conscious experience.
Blindsight
Focuses images on the retina.
Lens
Hearing loss from cochlea or nerve damage.
Sensorineural Deafness
Partial color blindness.
Dichromatism
Sense of smell.
Olfactory system
Perception from sensory receptors to brain.
Botton-Up Processing
Sense of balance and body position.
Vestibular Sense
Inability to recognize faces.
Prosopagnosia
A monocular cue that refers to hazy objects being farther away.
Relative Clarity
Ability to perceive sound frequency.
Pitch Perception
Converting stimulus energies into neural impulses.
Transduction
Cells that detect color and detail; for bright light.
Cones
Sensory control center in the brain.
Thalamus
Two stimuli must differ by a constant percentage to be perceived as different.
Weber’s Law
Pitch caused by all hairs in Cochlea moving together.
Volley Theory
A monocular cue that refers to smaller images being farther away.
Relative Size
Reduced sensitivity from constant stimulation.
Sensory Adaptation
Carries impulses from the eye to the brain.
Visual Nerve
Gestalt concept of grouping nearby figures.
Proximity
Visual images persisting after stimulus removal.
After-Images
Spinal cord blocks/allows pain signals.
Gate Control Theory
Gestalt concept of completing incomplete figures.
Closure
Opposing retinal processes enable color vision.
Opponet-Process Theory
Perceiving whole forms out of parts.
Gestalt Psychology
Distance between wave peaks.
Wavelength
Organizing and interpreting sensory information to understand the environment.
Perception
Depth from comparing retinal images.
Retinal Disparity
Lens change shape to focus on objects.
Accommodation
Framework organizing information.
Schema
Point where the optic nerve leaves the eye; no receptors.
Blind Spot
Predisposition to perceive certain things.
Perceptual Set
Clearer vision for distant objects.
Farsightedness
Sense of body part movement.
Kinesthesis
Depth cues for one eye.
Monocular Depth Cues
Perceptions from experiences (brain) to body.
Top-Down Processing
Eyes moving inward for depth.
Convergence
Gestalt concept of grouping similar figures.
Similarity
Monocular cue that refers to parallel lines converging with distance.
Linear Perspective
Hearing loss from mechanical system damage.
Conduction Deafness
Detecting physical energy and encoding it as neural signals.
Sensation
Detect black, white, gray; for low light.
Rods
Perceived highness or lowness of a tone.
Pitch
Complete color blindness.
Monochromatism
Light-sensitive inner eye surface with receptor cells.
Retina
Chemical signals for communication.
Pheromones
One sense perceived as multiple senses.
Synesthesia
Minimum stimulation needed to detect a stimulus 50% of the time.
Absolute Threshold
Depth cues for both eyes.
Binocular Depth Cues
Pitch linked to specific hairs in the Cochlea.
Place Theory
A Monocular cue in which coarse to fine texture signals distance.
Texture Gradient
Cells in the retina that convert light into electrical signals that the brain can use.
Photoreceptors
One sense influencing another.
Sensory Interaction
Focusing awareness.
Attention
