Module 9 Test Psy 320

Think of the three memory systems in the stage model and their capacity. Match each system with the correct description of its capacity. Sensory Memory Short-term Memory Long-term Memory

1. Relatively large. In between the other two systems. 2. Limited Capacity. Smaller than both of the other systems in terms of capacity. 3. Unlimited. Larger than the other two.

Match the examples of things Clive Wearing can or cannot do with the correct phrase. -Clive does not remember that he was a conductor before his illness. -Clive does not remember that he has just seen someone. -Clive can still write.

1. This is an example of retrograde amnesia. 2. This is an example of anterograde amnesia. 3. Example of a skill that is preserved.

Think about the Logie and Baddeley study in which participants counted the number of times a square flashed on the screen. The "Count Only" group performed this task alone. The "Tap" group also tapped their finger while counting the squares. The "The" group also said "the" over and over while counting squares. Suppose the outcome had been different and had instead demonstrated that tapping your finger or saying "the" over and over are both automatic tasks. Which of the following outcomes would indicate that the tapping and saying "the" tasks are automatic?

All three groups had the same very low number of errors

Is the following description of the results true or false? Given the immediate test (no delay), participants can remember all three words and after a delay of 18 seconds with a rehearsal prevention task during the delay they can still remember all the words.

False

Primacy describes a finding of better memory for words that appear late in the list relative to words that appear in the middle of the list.

False

The explanation for the recency effect is that these words have been stored in long-term memory.

False

Think about Graf and Schacter's study with amnesiac and control groups. Is the following a true description of the results and implications of this study? Amnesiacs and control had similar performance on the explicit test but amnesiac's had very poor performance on the implicit test. The findings were inconsistent with the stage's model's explanation of amnesia and demonstrated that amnesiacs could benefit from experience.

False

Think about the Logie and Baddeley study in which participants counted the number of times a square flashed on the screen. The "Count Only" group performed this task alone. The "Tap" group also tapped their finger while counting the squares. The "The group also said "the" over and over while counting squares. Is the following set of statements a True or False description of the results and implications of this study? The "Count Only" group had more errors than the other two groups and the " The" group had the lowest number of errors, with the "Tap" group in the middle. The results are consistent with the proposal that we have multiple storage components in working memory.

False

Think of the Brown-Peterson paradigm in which participants study 3 words for 3 seconds each. After studying the words, participants are given a recall test either immediately (zero delay) or after a delay ranging from 3 to 18 seconds. In the standard task participants engaged a rehearsal prevention task during the delay between study and test. Suppose participants had NOT engaged in rehearsal prevention during the delay and were free to rehearse the words. Which of these statements describe what would happen? (Pick 2)

Given the immediate test (no delay), participants can remember all three words. After a delay of 18 seconds participants can still remember all the words because rehearsal functionally extends the duration of short-memory.

At the time of test, participants are asked to remember information from a specific prior experience. This is a definition of which of the following?

Intentional Study Task

Think about the serial position effects. These effects occur when someone is immediately asked to recall the list words. Also think about the explanation for why we get a primacy effect and a recency effect. (i.e., relate the primacy and recency effects to short-term and long-term memory). What would happen if you asked someone to delay their recall and you had them engage in a rehearsal prevention task during the delay? Pick the statement that describes what should occur in this case.

The primary effect would still occur but the recency effect would be eliminated.

Simple span short-term memory tasks such simple forwards digit span reflect only storage capacity and do not measure processing capacity.
