Question

which of the following is the best operational definition of superior autobiographical memory?

a the ability to encode and retain information for later retrieval.

b recalling information about life events with over 90% accuracy.

c a memory that allows the relatively permanent retention of information without limits regarding how much information can be stored.

d a type of memory that relates to accumulated knowledge about the world.

Explanation:

An operational definition defines a variable in terms of the specific procedures used to measure or manipulate it. Superior autobiographical memory specifically pertains to the recall of personal life events.

• Option A is a general definition of memory (encoding, retention, retrieval) and not specific to autobiographical memory.
• Option C is an incorrect description as all memory (including autobiographical) has some biological and practical limits on storage, and it's not a standard definition of superior autobiographical memory.
• Option D describes semantic memory (knowledge about the world), not autobiographical memory.
• Option B, "Recalling information about life events with over 90% accuracy", is an operational - like definition (using a percentage for accuracy) that specifically targets autobiographical (life - event related) memory.

Answer:

B. Recalling information about life events with over 90% accuracy.
