Question

In the serial position effects demonstration, memory for the last few items in the list seems to be due to

Retroactive interference from other items in the list
Extra attention was paid to these items and rehearsal to get them into memory better
Proactive interference from other items in the list
Retrieval from short-term memory

Answer 1

In the serial position effects demonstration, memory for the last few items in the list is typically attributed to proactive interference from other items in the list. Proactive interference occurs when previously learned information interferes with the recall or retention of new information. In this case, the earlier items in the list may have already been stored in memory, causing interference and making it more difficult to remember the later items.
