Exam 8: Memory

Long-term potentiation refers to the process whereby:

Reasons for the distortion or manufacture of memories include all of the following EXCEPT:

Dan felt depressed for much of the semester because he was working quite a bit and applying to graduate school. During final exams, he became ecstatic when he heard that he was accepted to the school of his choice. Given state-dependent memory, how will this change in emotional state impact his performance?

Your text describes a study (Cahill, et al., 1994) in which participants either received a tranquilizer or a placebo and heard either an emotional or a neutral story. The accuracy of participants' story recall was then assessed. Which alternative below correctly names and identifies the variables in this study?

_________memories are those that can be consciously brought to mind.

Having done '21 for 21' shots, Deanna barely remembers her 21^st birthday. That is, her _________ memory is sketchy.

Your text suggests that with respect to retrieval, sequential is to simultaneous as ________ is to ________

What is another name for the parallel distributed processing model of memory?

Define priming.

Dr. Zimmerman is interested in the potential contribution of long-term potentiation to learning and memory. He administers one group of rats a drug that blocks long-term potentiation. Another group of rats receives an injection of an inert substance, such as sugar water. Next, he examines the rats' maze-running performance. Dr. Zimmerman measures two dependent variables: trials-to-criterion, the number of trials the rats require before they can run the maze without making any wrong turns; and savings-on-relearning, the reduction in trials-to-criterion when the rats' performance is examined several days later, after having had a break from the maze. Dr. Zimmerman finds that trials-to-criterion is higher among the rats given the drug than among the rats given the inert substance. Savings-on-relearning, though, is the same in the two groups of rats. How might Dr. Zimmerman interpret these results? Based on your text's discussion, is this result consistent or inconsistent with existing research on long-term potentiation?

Which of the following is probably the MOST plausible explanation of source misattribution?

Which psychologist is CORRECTLY matched with the memory stage he or she studied?

What structural changes to the brain are associated with a postmortem diagnosis of Alzheimer's disease?

The inability to recall information that was previously encoded is known as ________.

Sensory, working, and long term memory are often referred to as memory _________.

Anne was two years old when her mother died. Since that time, her Aunt Jane has frequently told her about how Anne and her mother would pick strawberries. Because of this repeated interaction, Anne believes that she "remembers" these trips with her mother when in fact, these memories are the result of the discussions. What type of memory distortion has occurred in this example?

Old information stored in long term memory must enter working memory for it to be active for use in an ongoing task.

In a comparison of average older participants and those with Alzheimer's disease, how much larger was the hippocampus of those with excellent memories?

Describe Freud's concept of repression and how this might serve as a mecahnism for motivated forgetting.

Describe how hypnosis might be one means of exposing individuals to memory distortions due to misinformation.
