Chap4: Sensation And Perception Flashcards
Light-sensitive tissue lining the back of the eyeball.
Retina
Monaku
The ability to see fine detail.
Visual acuity
The process by which the eye maintains a clear image on the retina.
Accommodation
コンタクト
Length of light waves
Hey or color
Light waves of amplitude
Brightness
The number of light waves
Tasty ration and richness of coler
Photo receptors that detect cooler, operate under normal daylight conditions, and allow us to focus on fine detail.
Cones
Photoreceptors that become active under low-light conditions for night vision.
Rods
An area of the retina where vision is the clearest and there are no rods at all.
Fovea
The region of the sensory surface that, when stimulated, causes a change in the firing rare of that neuron.
Receptive field
The pattern of responding across the three types of cones that provides a unique code for each color.
Trichromatic color representation
Pairs of visual neurons that work I. Opposition.
Color-opponent system
The part of the occipital lobe that contains the primary visual cortex.
Encoding edge orientation.
Area V1
Represent an object’s shape and identity
Go down
Ventral stream
To identity the location and motion of an object
Up
Dorsal stream
The inability to recognize object by sight
Ex: card no
Visual-form agnosia
How features are linked together so that we see unified object in our visual world rather than free-floating or miscombined features
Binding problem
A perceptual mistake wheee features from multiple objects are incorrectly combined.
Illusory conjunction
Misunderstanding what they saw
Bluex > red A
The idea that focused attention is not required to detect the individual features that comprise a stimulus but is required to bind those individual features together.
Feature integration theory
A perceptual principle stating that even as aspects of sensory signals change, perception remains consistent.
Perceptual constancy
A mental representation that can be directly compared to a viewed shape in the retinal image
Template
Aspects of a scene that yield information about depth when viewed with only one eye
Monocular depth cues
The difference in the retinal images of the two eyes that provides information about depth
Binocular disparity
Ex: interposition, etc
The perception of movement as a result of alternating signals appearing in rapid succession in different locations
Apparent motion
When people fail detect change to the visual details of a scene
Change blindness
How high or low a sound is
pitch
A sound’s intensity
Loudness
A fluid-filled tube that is the organ of auditory transduction
Cochlea
A structure in the inner ear that undulates when vibrations from the ossicles reach the cochlea fluid
basilar membrane
Specialized auditory receptor neurons embedded in the basilar membrane
Hair cells
A portion of the temporal lobe that contains the primary auditory cortex
Area A1
The cochlea encodes different frequencies at different locations along the basilar membrane
Place cord
The cochlea registers low frequencies via the firing rate of actin potentials entering the auditory nerve.
Temporal code
The active exploration of the environment by touching and grasping objects with our hands.
Hepatic perception
Feeling of pain when sensory information from internal and external areas converges on the same nerve cels in the spiral cord
Refereed pain
A theory of pain perception based on the idea that signals arriving from pain receptors in the body can be stooped, or gated, by interneurons I’m the spinal cord via feedback from two directions
Gate-control theory
The tree fluid-filled semicircular and adjacent organs located next to the cochlea in each inner ear.
Vestibular system
Receptor cells hat initiate the sense of smell
Olfactory receptor neurons ORNs
A brain structure located above the nasal cavity beneath the frontal lobes
Olfactory bulb
Biochemical odorants emitted by other members of its spices that can affect an animal’s behavior or physiology
Pheromones
