1) Neural network models often
a.have distributed processing.
b. store information discretely in isolated and independent units.
c.have static activation levels.
d. are symbolic in nature.
2) Which statement below is both true and suggestive that chimpanzees and bonobos
might have a conscious state?
a.They share a common ancestor with humans.
b. Their brains are split into hemispheres.
c.They can develop Capgras syndrome.
d. The scaffolding to storage framework proposes these species have a conscious state.
3) Assessment of the visual processing carried out by each hemisphere in split-brain
patients usually involves the brief simultaneous presentation of different stimuli to each
visual field while the participant fixates on a central point in space. Why is it necessary
to ensure that stimulus presentation is brief?
a.If the stimuli were presented over longer intervals, information would be transferred
between the hemispheres through the corpus callosum.
b. Brief presentation prevents participants from focusing attention on the stimuli.
c.The short presentation time is necessary to prevent eye movements, which would
redirect information across the visual fields.
d. Increasing the presentation time increases task difficulty for split-brain patients.
4) Which of the following brain structures is NOT directly involved in language?
a.sylvian fissure
b. angular gyrus
c.inferior parietal lobule
d. inferior frontal cortex
5) One difficulty in interpreting the correlation between asymmetry in the planum
temporale and language function that has recently arisen is that
a.the extent of the anatomical differences between the left and right hemispheres may
have been overestimated by the techniques used to identify this region.
b. it has been found that the planum temporale is an area of great plasticity that changes
in size throughout development.
c.newer studies indicate that the planum temporale is involved not in language function
but rather in vision.
d. current studies suggest that fewer people than previously thought have
left-hemisphere language dominance.
6) In one experiment a group of pictures was presented to split-brain patients. Then a
set of pictures was presented either to the left or the right hemisphere. Which of the
following statements is true?
a.The left hemisphere accurately identified only the previously presented pictures.
b. The right hemisphere misidentified related pictures as being presented.
c.both a and b
d. none of the above
7) In what way might the self-referent effect and the depth-of-processing effect be
related?
a.Information processed in relation to the self may benefit from the wealth of
information about the self in memory.
b. Information processed in relation to the self may be skewed by our biased
representations of our own personalities and traits.
c.The self is a special cognitive structure with unique mnemonic or organizational
elements.
d. The self has elements that promote processing in a way that is distinct from
other cognitive systems.
8) Patient Tan, studied by the neurologist Broca, had great difficulty in generating
spontaneous speech and was unable to utter any word other than the nonsense syllable
tan. Postmortem autopsy of Tans brain revealed
a.abnormal EEG signals from the left frontal operculum.
b. a lesion in the left inferior frontal cortex.
c.cerebral hemorrhage in the right inferior frontal lobes.
d. demyelination in a region of the left anterior frontal lobes.
9) You are driving in a car. Which of the following stops will require the most working
memory?
a.stopping at a supermarket
b. stopping at home
c.stopping at a friends home
d. stopping at a business you have never visited before
10) __________is the idea that the columnar organization in the adult cortex is derived
during development from the cells dividing in the ventricular region.
a.Topographic mapping
b. The sensory homunculus
c. The radial unit hypothesis
d. The ventricular zone hypothesis
11) Neurons in each half of the cerebellum synapse on _________ targets in the
thalamus and other subcortical structures, and therefore regulate the effectors on the
_________ side of the body.
a. ipsilateral ; ipsilateral
b. ipsilateral ; contralateral
c. contralateral ; ipsilateral
d. contralateral ; contralateral
12) The primary benefit that the nervous system gains from myelination is
a.generation of currents actively (action potentials) rather than passively (electrotonic
conduction).
b.decreased membrane resistance.
c.increased resting potentials.
d.faster neural communication.
13) Which of the following would be the most difficult for the famous patient H.M. and
other patients with medial temporal lobe removal?
a. reading a string of numbers written on a piece of paper
b. remembering a series of seven numbers for 20 seconds
c. learning the words for numbers in a foreign language
d. improving in the ability to write numbers with the nondominant hand
