Cognitive models of political behavior and political decision making have been a staple of research in political science for decades. Recent advances in cognitive psychology and behavioral decision making underscore the utility of models that incorporate memory dynamics for understanding a wide range of political behaviors at the individual level. Four memory systems are relevant; sensory memory, short-term memory, working memory, and long-term memory. Information moves from sensory memory to short-term memory stores, a subset of which is then acted upon by working memory. Working memory manipulates its contents through processes such as reasoning, comprehension, attention, integration, and retrieval of supplementary information from long-term memory. Working memory ultimately holds and processes the thoughts and feelings that are salient to an individual at a given point in time. Memory models of decision making elaborate what cognitions and emotions are likely to enter working memory and how those cognitions and emotions are combined and integrated when making a behavioral decision.
