Evidence that some cones are especially sensitive to red light, others to green light, and still others to blue light is most directly supportive of the __________ theory.
Young-Helmholtz
The direct link between a single cone and a single _________ preserves the fine details in the cone's message.
bipolar cell
Research participants picked one of two photographed faces as more attractive. When researchers cleverly switched the photos, participants readily explained why they preferred the face they had actually reflected. Their behavior illustrated
choice blindness.
The Gestalt principle that refers to an individual's tendency to perceive an incomplete figure as whole is called
closure
The basilar membrane is located in the
cochlea.
The ability to simultaneously recognize the color, shape, size, and speed of an oncoming automobile best illustrates
parallel processing.
Damage to the temporal lobe area of the brain essential for facial recognition produces a loss of
perception.
The receptor cells that convert light energy into neural signals are called
rods and cones.
In University of Utah driving-simulation experiments, students conversing on cell phones were slower to detect and respond to traffic signals. This best illustrates
selective attention.
The sequentially flashing Christmas tree lights appeared to generate pulsating waves of motion. This best illustrates
the phi phenomenon.
Which of the following is most closely associated with hairlike receptors in the semicircular canals?
Hearing
Which of the following explains reverse-color afterimages?
Hering's opponent-process theory
Feature detectors are neurons that are turned on or off by specific features of visual stimuli like edges and movement. Where in the visual system are these feature detectors located?
Occipital cortex
Which of the following is the correct path a neural impulse will follow through the different layers of the retina?
Rods and cones, bipolar cells, ganglion cells, optic nerve
What occurs when experiences influence our interpretation of data?
Top-down processing
An integrated understanding of perception in terms of our sensory capacities, cultural contexts, and Gestalt principles is most clearly provided by
a biopsychosocial approach.
The change in the curvature of the lens that enables the eye to focus on objects at various distances is called
accommodation
Which of the following sensations does NOT require transduction *
all require transduction
The rupture of an eardrum can lead to
conduction hearing loss.
Which of the following is the correct order of structures light passes through in the eye?
cornea, iris, pupil, lens, retina
Sensation is to __________ as perception is to __________.
detection; interpretation
Some people are better then others at detecting slight variations in the tastes of various blends of coffee. This best illustrates the importance of *
difference threshold.
Which process allows more light to reach the periphery of the retina?
dilation of the pupil.
Which of the following types of cells are located in the brain's occipital lobe?
feature detectors
While attending a concert, Anthony finds that he can clearly recognize the melody coming from the lead violin above all the other instruments playing in the orchestra, even though the other instruments may be louder. Gestalt psychologists would explain Anthony's ability using the principle of
figure-ground
Visual information is processed by
ganglion cells before it is processed by feature detectors.
The mechanical vibrations triggered by sound waves are transduced into neural impulses by
haircells.
Dilation and constriction of the pupil are controlled by the
iris.
The sense of smell is known as
olfaction.
Balanced is influenced by the
semicircular canals
Which theory can best explain why people respond differently to the same stimuli?
signal detection theory
The ability to pay attention to only one voice at a time is called
the cocktail party effect.
The pitch of a sound is determined by what?
the frequency of the sound wave
The axons of ganglion cells converge to form
the optic nerve.
The semicircular canals are most directly relevant to
the vestibular sense.
Heather Sellers suffers from prosopagnosia and is unable to recognize her own face in a mirror. Her difficulty stems from a deficiency in
top-down processing.
The process of converting incoming physical energy into a neural code that can be processed is called
transduction
The local fire department sounds the 12 o'clock whistle. The process by which your ears convert the sound waves from the siren into neural impulses is an example of
transduction.
The feature detectors identified by Hubel and Wiesel respond to specific aspects of ________ stimulation.
visual
Light's __________ is the distance from one wave peak to the next. This dimension determines the __________ we experience.
wavelength; hue
