Discussion

Given below are two statements, one labelled as Assertion (A) and the other labelled as Reason (R). Indicate your answer using the codes given below :

Assertion (A) : Working memory can hold a large amount of information even though it can retain only seven to nine items.
Reason (R) : Items in working memory contain several separate bits of information grouped together called chunks.
Codes :

  • A.Both (A) and (R) are true and (R) is the correct explanation of (A).
  • B.Both (A) and (R) are true, but (R) is not the correct explanation of (A).
  • C.(A) is true, but (R) is false.
  • D.(A) is false, but (R) is true.

Answer: A

Both statements are true, and (R) explains (A). Working memory can hold only about seven to nine items, but each item can be a chunk, several bits of information grouped together as one unit, so the total amount of information held can be large.

The reason therefore gives the mechanism by which the limited number of items can carry much information, so the first option is correct.
