chapter 5 sensation and perception Flashcards
the process through which the lens changes shape to bring objects into focus on the retina
accommodation
the location in the temporal lobe where auditory information is processed
auditory cortex
the tissue inside the cochlea where the hair cells are located
basilar membrane
auditory cues require comparing an image as it falls on both eyes in order to understand how far away an object is from the viewer
binocular depth cues
the processing of physical messages delivered to the senses
bottom up processing
sensory cells in the nose that respond to air molecules that we interpret as smell and taste
chemoreceptors
a snail shaped structure in the inner ear where the auditory hair cells are located
cochlea
cells in the visual striate cortex that respond to specific orientations in motion
complex cells
a type of photoreceptor in the retina that is typically most responsive to bright lighting conditions and is responsible for communicating information about acuity and color
cone
a term for several rare conditions where an individual is unable to experience pain
congenital angalgesia
the transparent covering of the eye; performs about 80% of the focusing of a visual image
cornea
part of the bipolar layer of the retina. These cells receive signals from the rods and send their messages to large (magno) ganglion cells
diffuse bipolar cells
Cones in the visual system that respond maximally to medium wavelengths of light (e.g., greens & yellows). Also known as M-cone
medium wavelength cones
specialized cells in the visual cortex that respond most actively to specific stimuli
feature detectors
the theory of audition that suggests we understand pitch because of the rate of cellular firing on the basilar membrane
frequency theory
also known as the Where stream, this pathway takes information from the occipital lobe to the parietal lobe, where we are able to identify object location
dorsal stream
the physical measurement of pitch, or how high/low a sound it
frequency measured in Hz
the portion of the retina directly behind the pupil. It contains a large concentration of cones and NO rods
fovea
a theory of pain perception that suggests that painful stimuli can be blocked in the spinal cord when you are engaged in other activities
gate control theory of pain
the physical distance from one energy cycle to the next; changes in wavelength are often perceived as changes in colour
wavelength
the location in the occipital lobe where visual information is organized and analyzed
visual striate cortex
also known as our sense of balance
vestibular sense
the structures in the inner ear that respond to cues associated with balance and posture
vestibular sacs
also known as the What stream, this pathway takes information from the occipital lobe to the temporal lobe where we are able to identify an object
ventral stream
A theory of color vision that proposes that color information is identified by comparing the activation of different cones in the retina.
trichromatic theory
The process by which external sensations are converted into neural firing in the brain.
transduction
Also known as the eardrum, this structure transfers energy to the three smallest bones of the body known as the ossicles.
tympanic membrane
The integration of a person’s beliefs, memories, and expectations into their sensory experiences to create a perception.
top down processing
The spatial organization of the basilar membrane is maintained through the auditory pathway.
tonotopic organization
receptors in the skin specifically designed to detect changes in temperature
thermoreceptors
the location of taste sensitive cells on the tongue
taste pore
