levels of processing

A continuum of memory processing from shallow to intermediate to deep, with deeper processing producing better memory.

anterograde amnesia

A memory disorder that affects the retention of new information and events.

Jen's dad sends her to the grocery store for a few last-minute dinner items.

B) Exercise tends to degrade information if it has just been learned.
