Iconic memory discrete visual sensory register that holds information for very short periods. Chunking: chunk memory unit that consists of several components that are strongly associated with one another, memory performance depends on how information is chunked, capacity estimates vary, magical number 7 (7 +/- 2) miller (1956) Standard explanations: primacy effect, memory advantage for first items in a list, reflects long-term memory. Items are rehearsed more: recency effect, memory advantage for last items in a list, reflects short-term memory, last items still in short-term memory at time of recall. Integrates information: phonological loop, visuospatial sketchpad, episodic buffer, long term memory, plays a role in selecting strategies, transforming information, and coordinating behavior, used for both selective and divided attention: it can focus or distribute attention.
