COG Psych Exam 2 Questions And Correct Answers
Deep processing may lead to improved memory performance because it facilitates
retrieval. How exactly does this happen? - ANSWER Deep processing forms many
connections between the current item and previous knowledge.
Peter has a higher working memory capacity than Josh. Given previous correlational
evidence, who would you expect performs better on intelligence tests? - ANSWER Peter
The modal model holds the belief that information processing makes use of at least two
kinds of memory: working memory and long-term memory. Working memory differs from
long-term memory in that? - ANWER It is easier for one to access the stored items in
working memory.
Anterograde amnesia results from damage to the? - ANSWER Hippocampus
An experimenter reads a list of 30 words to a group of participants at the rate of one
word per second. This is immediately followed by a free-recall test. A second group of
participants hears the same 30 words presented at the faster rate of two words per
second. We should expect that the group hearing the slower presentation will show
improved memory performance for the? Answers This will be the pre-recency portion of
the list, but there will be no effect on the recency effect. This is due to the fact that
longer presentation of pre-recency portion allows more time for rehearsal and thus
increasing the chances for the items to be transferred into the long-term memory.
According to the modal model of memory, words presented early in a list are easier to
remember than words presented later because? - ANSWER The early words receive
more of the participants' attention than the later words.
A doctor has just read an article about a newly invented drug. Which of the following is
LEAST important in determining whether the doctor will remember the article later on? -
ANSWER The doctor expected to need the information later on and therefore employed
a maintenance memorization strategy that she believed had helped her memorize
, material in the past.
Identify 3 types of physiological changes associated with the formation of memories. -
ANSWER 1.) Growth of new synapses
2.) Pruning of synapses
3.) LTP
Where in the brain do memories reside? - ANSWER In those parts of the cortex which
originally processed the information.
What are the 2 types of receptors on the dendritic spines of the post-synaptic cell
involved in LTP? - ANSWER AMPA & NMDA
What is the name of the space between the presynaptic and postsynaptic cells?
-ANSWER The synapse
Why does repeated stimulation bear necessity for the induction of LTP? -ANSWER To
depolarize the post-synaptic cell enough to expel magnesium ions (mg2+) from the
NMDA receptor channel.
An eyewitness to a crime is quite confident that his memory of the crime is correct. What
should the jury considering his testimony keep in mind? - ANSWER Memory confidence
is a poor indicator of memory accuracy.
EXERCISE Dmitri witnessed a bank robbery but appears to have no memory for what he
saw. A friend hypnotizes Dmitri and, in the hypnotic state, asks him to remember the
crime. Research indicates that, if asked under hypnosis? - ANSWER Dmitri will describe
the crime in greater detail than previously but no more accurately.
Intrusion errors in memory are errors? - ANSWER In which other knowledge intrudes
into the remembered event.
