'''Cognitive psychology''' is the scientific study of mental processes — attention, perception, memory, reasoning, decision-making, and problem-solving — as computational operations performed by the brain. It emerged in the 1950s as a deliberate rejection of behaviorism's refusal to theorize about internal states, and it has since become the dominant framework for understanding how humans acquire, represent, and manipulate information.

== The Computational Metaphor ==

The foundational assumption of cognitive psychology is that the mind is an information-processing system: it receives inputs, performs computations on internal representations, and produces outputs. This '''computational metaphor''' has been extraordinarily productive, yielding precise models of memory retrieval, language parsing, visual object recognition, and decision-making under uncertainty. But it has also been criticized for treating the brain as a digital computer — a device with discrete symbols, explicit rules, and centralized control — when the brain is actually a massively parallel, distributed, and self-organizing network.

The tension between the computational metaphor and the biological reality of the brain is one of the defining problems of cognitive psychology. Early models (e.g., [[Atkinson-Shiffrin memory model]]) assumed serial processing and distinct memory stores. Later models (e.g., connectionist networks, [[Neural network|neural networks]]) assumed parallel distributed processing and emergent properties. The field has oscillated between these poles without resolving the fundamental question: is cognition best understood as rule-based symbol manipulation or as pattern-based statistical learning?

== Core Domains ==

'''Attention.''' The selective enhancement of some inputs over others. Attention is not a single process but a family of mechanisms — sustained attention, selective attention, divided attention, executive attention — each with different neural substrates and different functional roles. The study of attention has been revolutionized by cognitive neuroscience, which has revealed that attention is not merely a filter but a modulator of sensory processing at every stage.

'''Memory.''' The encoding, storage, and retrieval of information. Cognitive psychology distinguishes between sensory memory, short-term (working) memory, and long-term memory, and between explicit (declarative) and implicit (procedural) memory. The [[Working memory|working memory]] model of Baddeley and Hitch has been particularly influential, positing a central executive, a phonological loop, and a visuospatial sketchpad.

'''Decision-making.''' The process of choosing among alternatives under conditions of uncertainty. Cognitive psychology has identified systematic biases in human decision-making — the availability heuristic, the representativeness heuristic, anchoring, framing effects — that reveal the mind's reliance on fast, approximate strategies rather than optimal computation. The [[Heuristics and biases|heuristics-and-biases]] research program of Kahneman and Tversky has had enormous influence on economics, policy, and design.

'''Language.''' The mental processes underlying the production and comprehension of language. Cognitive psychology has produced detailed models of lexical access, syntactic parsing, and discourse comprehension, and has revealed the online nature of language processing — the mind does not wait for a sentence to end before beginning to interpret it.

== Connection to Systems Thinking ==

Cognitive psychology is increasingly relevant to systems theory and cybernetics because it provides the theoretical foundation for understanding how humans interact with complex systems. The [[Situation Awareness]] model of Endsley, the [[Mental model|mental models]] research of Gentner and Stevens, and the [[Distributed cognition|distributed cognition]] framework of Hutchins all draw on cognitive psychology to explain how individuals and groups maintain understanding of complex, dynamic environments.

The [[Out-of-the-Loop Unfamiliarity]] problem in automation is fundamentally a cognitive psychology problem: the operator's mental model of the system decays when the automation closes the feedback loop without providing information that updates the model. The [[Automation Complacency]] problem is also a cognitive psychology problem: the operator's attention allocation is governed by expectancy and workload, and reliable automation reduces both, leading to disengagement.

Cognitive psychology also informs the design of [[Algorithmic Institution]]s: if the institution's rules are to be followed by humans, they must be designed with an understanding of human memory limitations, attention constraints, and decision-making biases. An institution that assumes rational actors is an institution that will be gamed by actors who are predictably irrational.
