9) The nodes of Ranvier are
a.vesicles of neurotransmitters, stored in presynaptic neurons.
b.points along axons where sodiumpotassium pumps are found.
c.vesicles of calcium ions, stored in postsynaptic neurons.
d.points along axons that are not surrounded by myelin.
10) All of the following describe differences between early-selection and late-selection
models of attention EXCEPT
a. early-selection models argue that selection occurs before semantic analysis of
incoming stimuli.
b. late-selection models argue that human information processing has limited capacity,
whereas early-selection models argue that capacity is unlimited.
c. early-selection models argue that all higher-level information processing requires the
use of attention.
d. late-selection models argue that a stimulus may be categorized or even identified
before selection.
11) A major issue in the study of word recognition involves the extent to which
relatively low-level sensory representations interact with relatively high-level
information, such as the context in which a word appears. A modular model of word
comprehension would be most likely to argue that
a.there is a great degree of interaction between low-level and high-level representations.
b. processing at each level is independent, and there is little or no interaction between
them.
c.certain levels may interact freely, whereas others cannot.
d. the degree to which the levels of word processing interact with each other depends on
the type of word being processed.
12) Which of the following best describes the flow of information in the Atkinson and
Shiffrin (1968) modal model of memory?
a. short-term storage long-term storage sensory memory
b. short-term storage sensory memory long-term storage
c. sensory memory short-term storage long-term storage
d. sensory memory long-term storage short-term storage
