PSYCH 46A ZAPS FOR MIDTERM 1
What is meant by the term "chunk" in the context of working memory? - CORRECT ANSWER-
A chunk is a unit of information that is grouped in a meaningful way.
Why might memory span for digits and letters (like "2" or "T") be better than for unfamiliar
nonsense syllables (like "gorb" or "trep")? - CORRECT ANSWER-because nonsense syllables
are difficult to stare as "chunks" since they're unfamiliar - chunks must be organized
meaningfully to be effective.
What would be the. best way to remember the following sequence by chunking?
247314911 - CORRECT ANSWER-24-7-314-911
In this memory span task, most people's memory span for letter with different sounds is
better than their memory span for letters that sound the same. Why might this be? -
CORRECT ANSWER-Most people repeat the letters to themselves to remember them, so
when the letters sound the same it is easier to mix them up.
Magdalena is a TA grading a set of chemistry quizzes. As she grades each quiz, she observes
that it is far more difficult to remember the sequence of correct answers for the multiple-
choice questions—A, D, C, C, B, D, A—than it is to remember the answers to the fill-in-the-
blank questions—helium, boron, chlorine—even though she has to keep far fewer letters in
her mind in total for the multiple-choice questions (7) than for the short-answer questions
(19). What is the primary reason for this? - CORRECT ANSWER-Because the 19 letters in
"helium, boron, chlorine" are arranged into meaningful chunks (words).
This operation span task measures working memory by... - CORRECT ANSWER-testing how
well you can remember words while solving math problems
the difference between short term memory and working memory is that.... - CORRECT
ANSWER-short-term memory describes a temporary information store, while working
memory also involves processing or manipulating information
