At the Grocery Store I Forget a Number of Things

Multiple Choice

At the grocery store I forget a number of things that were on a list that I was mentally trying to remember. I left the actual list at home. When I look at the list when I get home, I notice that I forgot all the things that were in the center of the list. The items at the beginning and end of the list I purchased. This is to be expected considering:

A) priming is not the greatest way to remember things
B) the serial position effect
C) recognition tasks are less than perfect
D) the random nature of free-recall tasks
