Sensory Adaptation
A person with monochromatism would most likely
have normal color vision but poor depth perception
experience color afterimages due to cone fatigue
see the world only in shades of gray
have difficulty distinguishing between red and green hues
Ganglion cells in the retina are responsible for
adjusting the size of the pupil based on light levels
transducing light energy into neural impulses
detecting color differences between short and long wavelengths
sending visual information from the eye to the brain via the optic nerve
Compared with cones, rods are more sensitive to
peripheral vision and red wavelengths
bright light and motion
dim light and black-and-white vision
color and fine detail
A person who is nearsighted can
focus light behind the retina
focus light directly on the retina
see close objects clearly but not distant ones
see distant objects clearly but not close ones
The blind spot in the eye exists because
there are no cones in the fovea
light is refracted by the lens
the optic nerve leaves the eye, creating an area with no receptor cells
rods are less sensitive to light at this location
The smell of freshly baked cookies enhancing their perceived taste best illustrates
top-down processing
sensory adaptation
sensory interaction
the gate control theory
Sensation occurs when
we focus on particular stimuli in the environment
previous experiences shape perception
sensory receptors detect physical energy from the environment and encode it as neural signals
the brain interprets sensory input
The absolute threshold refers to
the difference between sensation and perception
the point at which a stimulus becomes subliminal
the minimum stimulation needed to detect a stimulus 50% of the time
the smallest detectable change in stimulus intensity
After wearing a watch for a few minutes, you no longer notice its pressure on your wrist due to
bottom-up processing
Weber’s law
sensory adaptation
habituation
When recognizing a letter by first detecting its lines, angles, and curves, you are using
top-down processing
bottom-up processing
sensory adaptation
transduction
The difference threshold is best defined as
the minimum amount of energy needed to detect a stimulus
the point at which a stimulus becomes consciously noticeable
the smallest change in stimulation that can be detected 50% of the time
the point at which adaptation occurs
According to Weber’s law, two stimuli must differ by
a constant minimum percentage rather than a constant amount
a constant absolute value
an amount determined by sensory adaptation
a fixed intensity level for all senses
According to the trichromatic theory, the retina contains receptors that are sensitive to
red-green and yellow-blue opponent pairs
yellow, blue, and red hues
black, white, and gray tones
red, green, and blue wavelengths
The primary function of the lens is to
detect color
focus light onto the retina by changing shape
control the amount of light entering the eye
transmit signals to the optic nerve
Compared to blue light, red light has
(Think: Clifford with a deep bark)
a shorter wavelength and higher frequency
a longer wavelength and lower frequency
a shorter wavelength and lower frequency
a longer wavelength and higher frequency
Sensorineural hearing loss results from damage to
the eardrum or ossicles
the cochlea’s hair cells or the auditory nerve
the middle ear bones
the outer ear canal
The place theory of pitch perception suggests that
the rate at which neurons fire determines pitch
different sound frequencies stimulate different locations on the basilar membrane
all auditory neurons fire in synchrony with sound waves
pitch perception depends only on sound amplitude
According to the frequency theory,
pitch is determined by differences in air pressure
the rate of nerve impulses matches the frequency of the sound wave
sound waves are transduced by the semicircular canals
pitch is determined by where the basilar membrane is stimulated
The taste of umami is best described as
savory or meaty
sweet and pleasant
salty and mineral-rich
sour and citrus-like
Why do certain smells trigger vivid memories?
Olfactory information bypasses the thalamus and goes directly to brain areas linked to emotion and memory
The olfactory bulb transmits signals only to the visual cortex
Smells are stored as long-term procedural memories
The hippocampus suppresses emotional responses to odors
Kinesthesia refers to
awareness of external environmental stimuli
sensitivity to touch and pressure
balance and spatial orientation controlled by the inner ear
the ability to detect body position and movement of body parts
The semicircular canals in the inner ear are most directly involved in
regulating blood pressure
hearing
processing auditory pitch
detecting acceleration and balance
According to the gate-control theory, pain signals can be blocked or allowed to pass to the brain by
the semicircular canals
competing neural activity in the spinal cord
the frequency of auditory nerve firing
sensory adaptation in the somatosensory cortex
When you spin around and suddenly stop, the dizziness you feel is primarily caused by
