A patient suffering from Korsakoff’s syndrome, such as “Jimmy G” who is described in your text, would be able to perform which of the following activities without difficulty? a) following the plot of a story in a book b) solving problems that take more than a few moments to figure out c) recognizing people he has recently met d) Î identifying a photograph of his childhood home 2. Coding refers to the way information is . ... a) processed. b) Î represented. c) stored. ## This answer has to be counted as correct, as well as (b) because it could be argued that in order to store information, it must be coded in some way. This is not a strong argument for this answer ("stored") but we'll allow it. In the future, we need to rewrite this question to avoid this kind of issue. ## d) presented. 3. Which of the following is evidence that working memory includes a phonological loop that maintains representations of speech or speech-like sounds? a) Î Articulatory suppression eliminates the word-length effect. b) Self-generated associations are better memory cues than associations that were produced by someone else. c) Maintenance rehearsal is a less effective strategy for learning new material than is elaborative rehearsal. d) The average memory span for unrelated letters is about 7 letters. 4. In the Brown/Peterson task, subjects are shown three letters and a number. Subjects are required to remember the three letters while counting backwards by 3's from the given number. After a set period of time, e.g., 3 seconds or 18 seconds, subjects are asked to recall the letters. A standard result is that subjects achieve 75% correct after 3 seconds, but only 10% correct after 18 seconds. This finding is evidence for what hypothesis? a) Short-term memory has limited capacity. b) Î Active maintenance is needed to retain information in short-term memory. c) Retention in short-term memory depends on active monitoring by a central executive. d) Counting backwards interferes with retrieval of the three letters from long-term memory. 5. The Brown/Peterson task is described in Questions 4. Peterson and Peterson (1959), who pioneered the investigation of this task, hypothesized that the decrease in performance over longer delays was due to _____ but later research showed that it was actually due to _____. a) interference; decay

The significance of this finding was that .
