Three stage model of memory (atkinson & shiffrin 1968) *briefly holds sensory information (e. g. iconic and echoic stores ex- *stores and processes information of which we are conscious.

Short-term memory as a working memory (baddeley & hitch, *directs attention, recall from ltm, and integration of input. *ltm can endure for a lifetime (bahrick et al. , 1994) Retrieval of ltm = recall and recognition and encoding. Developing schemas allows development of expert knowledge (boschker et al. , 2002) Levels of processing theory of encoding (craik & lockhart, 1972) Deeper processing leads to better retrieval of information. Information is held in short-term memory (in the hippocampus) via reverberating neuronal activi- ty.
