The primacy effect explains why we remember:

The primacy effect explains why we remember:

• A. The beginnings and endings of information best
• B. The middle portions best
• C. The overall average of a sequence
• D. The most recent events only

Answer: (A)

The main idea here is the serial position effect, focusing on the primacy component. The primacy effect happens because the first items in a list get extra attention and rehearsal, making them more likely to be encoded into long-term memory. Items in the middle tend to be rehearsed less, so they aren’t recalled as well. The endings are remembered well too, but that’s due to the recency effect—they’re still in short-term memory at recall. So the primacy effect explains why the beginnings are remembered best. The broader pattern includes both primacy and recency, but the specific influence of the primacy effect is on the initial items.
