II and III only
Hyrum is at a concert when a flute player hits a very high note at the end of a song. Which of the following best explains why the pitch of the note sounds so high?
It has a short wavelength and high frequency.
Which of the following is true about the blind spot in the eye?
It occurs where the optic nerve leaves the eye.
Makayla and Noah are listening to a song that ends with all the instruments playing the same note. Makayla can distinguish the various instruments playing the note, while Noah cannot. Which of the following best explains their perceptual differences?
Makayla is better at discriminating timbre than Noah.
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
After staring at a green, black, and orange "American flag" for about a minute, an individual will see a red, white, and blue flag afterimage. Which of the following explains this phenomenon?
Opponent-process theory
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
John walks into art class and is overwhelmed by the smell of paint. However, the longer he stays in the room, the less noticeable the smell becomes. Which of the following appears to be operating in this instance?
Sensory adaptation
Laura arrives at a park that is located very close to a factory that produces cookies. She immediately notices the strong odor of chocolate chip cookies, but after a while she no longer detects the smell of the cookies. This can best be explained by which of the following?
Sensory adaptation
When Rosa has a cold, she cannot taste the flavor of her pizza. Which of the following psychological terms describes Rosa's inability to taste?
Sensory interaction
The table above is most likely to be used in a study investigating which of the following?
Signal detection
Ernst Weber's and Gustav Fechner's psychophysical laws concern the relation between which of the following?
The intensity of a stimulus and its corresponding psychological sensation
Which of the following explains transduction?
The process by which sensory stimuli are converted into neural signals
Julia is practicing her trumpet and produces a loud sound. Which of the following is the best explanation for the loudness of the sound?
The sound has a high-amplitude sound wave.
When Kaylee's friends discovered she was going to have her tonsils removed, they told her she was going to be in a great deal of pain. After the surgery Kaylee reported that she was in a lot of pain, although most of her pain should have been alleviated by her pain medication. Given this scenario, which of the following best explains Kaylee's reporting of pain?
Top-down processing
The intensity at which a sound becomes audible for a given individual is known as the individual's
absolute threshold
The change in the curvature of the lens that enables the eye to focus on objects at various distances is called
accommodation
People who are color blind most likely have deficiencies in their
cones
Ernie comes in from outdoors on a bright, sunny day and finds it to be very dark inside. Over the next few minutes, however, it becomes easier for Ernie to see inside. The perceptual process this scenario is describing is
dark adaptation
A person is asked to listen to a series of tones presented in pairs, and asked to say whether the tones in each pair are the same or different in pitch. In this situation the experimenter is most likely measuring the individual's
difference threshold
A subliminal stimulus is a stimulus that
falls below the threshold for conscious detection
Visual acuity is best in the
fovea
The psychological experience of pitch is related to a sound wave's
frequency
If Carmelita stares at a red spot for one minute and then shifts her gaze to a white piece of paper, she is likely to experience an afterimage that is
green
A sound is often detected by one ear more intensely and a fraction of a second earlier than it is detected by the other ear. These cues help individuals determine the
location of the source
David Hubel and Torsten Wiesel's research on responses of the brain to visual stimuli showed that
many cortical cells respond most strongly to specific visual information
In the dark, an object is more clearly seen when viewed in peripheral vision than when viewed directly. This phenomenon occurs because the rods located in the retina are
more sensitive in the dark than cones and are not found in the fovea
The most common form of color blindness is related to deficiencies in the
red-green system
In vision, transduction occurs within the
retina
On his first day of work at the bakery, Brad was nearly overwhelmed by the sweet odor of the baked goods. However, by lunchtime, he did not even notice the smell. This is an example of
sensory adaptation
A reason that one typically does not notice a blind spot in the visual field is that
the brain fills in missing information so there is no awareness that the visual field is incomplete
Evidence for the opponent-process theory of color vision is provided by the fact that
the eyes see negative afterimages after staring at saturated colors for several minutes
Negative afterimages are explained by
the opponent-process theory
Luz, a math major, sees the drawing above as a Venn diagram. Her brother, an art major, sees it as two circles. The difference in perception is an example of
top-down processing
People listening to rock music played backward often perceive an evil message if specifically told what to listen for. That phenomenon best illustrates
top-down processing
The general function of the bones in the middle ear is to
transfer sound information from the tympanic membrane to the oval window
Scott lost his vision at a young age. When he was much older, he received a corneal transplant that allowed him to see again. After so many years of not being able to see, he had a very difficult time interpreting visual information such as faces and expressions. His visual problems most likely came from processing difficulties in the
visual cortex
