PSY 461 EXAM 1 QUESTIONS AND CORRECT
ANSWERS
One problem with introspection as a method is that it_________________________. -
Answers - Introspective methods rely entirely on aspects of subjective phenomena that
are consciously accessible, which we now know represents only a small portion of what
is involved in cognition. Additionally, the subjective nature of these impressions makes it
difficult to confirm or disconfirm their validity. (Both b and c)
Which of the following synaptic changes have been proposed to mediate learning and
long-term memory formation? - Answers - Structural changes supporting LTM come in
many varieties, including the three forms of synaptic modification listed here. (all of the
above)
Hermann Ebbinghaus developed a method for measuring memory by comparing the
time it takes to relearn something with the time it took to learn it originally. This method
is known as_________________. - Answers - the method of savings
TMS is a technique that uses focused magnetic fields to temporarily alter activity in
target brain areas, with the goal of clarifying the relationship between brain structure
and function. - Answers - True
Introspection is a method of understanding cognition that relies on observations of our
own subjective mental states. - Answers - True
The brain is separated into left and right hemispheres that communicate via a large fiber
bundle called the - Answers - Corpus callosum
Long-term memory is thought to involve structural changes in the connections between
neurons, whereas short-term memory involves the sustained activation of neurons
tuned to particular stimulus properties (e.g., spatial locations, colors, etc.). - Answers -
True
The key attribute differentiating neurons from other types of cells is the relative
complexity of their cellular machinery. - Answers - False; The key defining property of
neurons is the property of electrical excitability, which allows them to communicate with
other neurons via electro-chemical signaling.
The event-related potential (ERP) method has__________________________,
whereas functional Magnetic Resonance Imaging (fMRI)
has___________________________. - Answers - excellent temporal precision and
poor spatial precision/poor temporal precision and excellent spatial precision
