Sensation & Perception Flashcards
A Monocular cue. Closer objects block farther ones.
Interposition
Three color receptors (red, green, blue).
Trichromatic Theory
Height of a wave.
Amplitude
Gestalt concept-Distinguishing objects from background.
Figure and Ground
Missing changes in the environment when vision is interrupted.
Change Blindness
Focusing on one voice in a crowd.
Cocktail Party Effect
Sense of taste.
Gustation
Inner ear canals for balance.
Semicircular Canals
Missing visible objects when focused elsewhere
Inattentional Blindness
Focusing on a particular stimulus.
Selective Attention
Clearer vision for nearby objects.
Nearsightedness
Responding to visual stimuli without conscious experience.
Blindsight
Focuses images on the retina.
Lens
Hearing loss from cochlea or nerve damage.
Sensorineural Deafness
Perception from Sensory receptors to brain.
Bottom-Up Processing
Sense of smell.
Olfactory System
Sense of balance and body position.
Vestibular Sense
Inability to recognize faces.
Prosopagnosia
A Monocular cue. Hazy objects are farther away.
Relative Clarity
Ability to perceive sound frequency.
Pitch Perception
Converting stimulus energies into neural impulses.
Transduction
Cells- detect color and detail; for bright light.
Cones
Sensory control center in the brain.
Thalamus
Pitch caused by all hairs in Cochlea moving together.
Volley Theory
Two stimuli must differ by a constant percentage to be perceived as different.
Weber’s Law
Monocular cue. Smaller images are farther away
Relative Size
Reduced sensitivity from constant stimulation.
Sensory Adaptation
Carries impulses from the eye to the brain.
Visual Nerve
Gestalt concept. Grouping nearby figures.
Proximity
Gestalt concept. Completing incomplete figures.
Closure
Spinal cord “gate” blocks/allows pain signals.
Gate Control Theory
Opposing retinal processes enable color vision.
Opponent-Process Theory
Perceiving whole forms out of parts
Gestalt
Distance between wave peaks.
Wavelength
Depth from comparing retinal images.
Retinal Disparity
Organizing and interpreting sensory information to understand the environment.
Perception
Lens changes shape to focus on objects.
Accommodation
Point where the optic nerve leaves the eye; no receptors,
Blind Spot
Framework organizing information.
Schema
Predisposition to perceive certain things.
Perceptual Set
Sense of body part movement.
Kinesthesia
Clearer vision for distant objects.
Farsightedness
Depth cues for one eye.
Monocular Depth Cues
Perceptions from experiences (brain) to body.
Top-Down Processing
Eyes converging inward for depth.
Convergence
Monocular cue. Parallel lines converging with distance.
Linear Perspective
Hearing loss from mechanical system damage.
Conduction Deafness
Gestalt concept. Grouping similar figures.
Similarity
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
Partial color blindness.
Dichromatism
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 using both eyes.
Binocular Depth Cues
Pitch linked to specific hairs in the Cochlea.
Place Theory
A Monocular cue. Coarse to fine texture signals distance
Texture Gradient
One sense influencing another
Sensory Interaction
Focusing awareness.
Attention
Visual images persisting after stimulus removal.
After Images
Information processing where we construct perceptions from our experiences and expectations.
