Question: 246
3. The inability to form new memories is called:
- A. retrograde amnesia.
- B. anterograde amnesia.
- C. source amnesia
- D. infantile amnesia.
Correct Answer: B
Explanation:
Anterograde amnesia is defined as the inability to form new memories (choice B is correct). Retrograde amnesia is defined as the inability to retrieve information from one's own past (choice A is wrong). Source amnesia is defined as the attribution of an event one has experienced, heard about, or imagined to the wrong source (choice C is wrong). Infantile amnesia is used to explain why individuals are typically unable to remember anything from before the age of 3; the human brain pathways are not yet fully developed enough to form memories at this age (choice D is wrong).
