Final answer:
The inability to recall a grocery list until seeing the items in a store is an example of cue-dependent forgetting, where retrieval of stored information requires cues from the original context.
Step-by-step explanation:
Being unable to recall your grocery list until you are at the store and see some of the items you need on the shelves is an example of cue-dependent forgetting. This phenomenon occurs when information is stored in your memory, but you cannot retrieve it until a specific cue associated with the original context of the memory is presented. It is not proactive interference, which is when old information hinders the recall of newly learned information. It is also not retroactive interference, where more recently learned information hinders the recall of older information. Lastly, it is not anterograde amnesia which is the inability to remember new information typically following a brain trauma.
Being unable to recall your grocery list until you are at the store and see some of the items you need on the shelves is an example of cue-dependent forgetting. When we encode information, cues and contexts are stored along with it. These cues and contexts act as reminders for retrieval. In this case, seeing the items on the shelves serves as a cue that triggers the recall of the grocery list.
