This document provides an overview of key concepts in memory and cognition. It covers the difference between memory and cognition, the Atkinson-Shiffrin model of memory with sensory memory, short-term memory and long-term memory, encoding types like semantic and deep processing, memory organization models, long-term potentiation, the method of loci, distributed vs massed practice, and reasons for forgetting like interference and failure to encode. Key terms defined include iconic, echoic and selective attention, as well as anterograde and retrograde amnesia.
