an older person saying \i know the answer, but i just cant remember\ indicates a difficulty with:\n○…

Brief Explanations:

Recall refers to the ability to retrieve information from memory. The statement shows the person knows the information (so storage/processing isn't the issue) but can't retrieve it, which is a recall difficulty. Processing involves encoding, sensory term memory is not a standard term (maybe a typo, and sensory memory is short - term sensory info), storage is about retaining info (they know it's stored). So the issue is recall.

Answer:

recall.
