2 - Perception Flashcards
Q
Theory that rays of light emanating from the eye, in combination with light from the environment, produces vision (disproven)
Extramission Theory
Q
Theory that rays of light reflected from objects into the eye produce vision (proven)
Intromission Theory
Q
Transparent, flexible structure that focuses light rays falling on the retina
Lens
Q
Muscle that adjusts the lens
Ciliary Muscle
Q
Curvature of the lens adjusting to alter the visual field
Accommodation
Q
Neural tissue lining the inside back portion of the eye
Retina
Q
Specialized visual receptor cells that are central to daytime and colour vision
Cones
Q
Specialized visual receptor cells that are central to night vision, peripheral vision, directing vision, and detecting motion
Rods
Q
Spot in the center of the retina that contains only cones, where visual acuity is greatest
Fovea
Q
Focusing the fovea directly on a stimulus
Foveating
Q
Theory that the human eye has 3 different types of cones that are each sensitive to a specific wavelength (colour)
Trichromatic Theory
Q
Cues about distance based on the varying views of each eye
Binocular Cues
Q
Closer objects seem to move faster, while distant objects seem to move slower
Motion Parallax
Q
An object becoming so distant that both eyes have the same view, and it is impossible to tell its distance
Perceptual Infinity
Q
Cues about depth that can be observed in a 2D/flat image
Pictural Depth Cues
Q
Processes details about what objects are (form, colour, lines, etc.)
Ventral (What?) Stream
Q
Processes details about where objects are in space (motion, depth, etc.)
Dorsal (Where?) Stream
Q
External ear, acts as a cone for collecting sound and funneling it along the ear canal to the eardrum
Pinna
Q
Receives soundwaves from the pinna and transmits vibration to the ossicles
Tympanic Membrane (Eardrum)
Q
Set of 3 tiny bones in the inner ear, amplify small changes in air pressure
Ossicles
Q
The process of locating the source of a sound in space
Auditory Localization
Q
Determining the location of an object using echoes
Echolocation
Q
The sensory system for taste
Gustatory System
Q
Clusters of taste receptors that line the tongue
Taste Buds
Q
Sweet, sour, bitter, salty, umami (savoury)
Primary Tastes
Q
The sensory system for smell
Olfactory System
Q
The perception of where the body is in space
Proprioception
Q
The perception and control of how the body moves
Kinesthesia
Q
Portion of the inner ear, provides a sense of balance and spatil orientation
Vestibular System
Q
Perception of sensations from inside the body (hunger, thirst, excretion, heart rate, digestion, etc.)
Interoception
