Connectionism refers to both an approach in the field of cognitive science that hopes to explain mental phenomena using artificial neural networks (ANN) and to a wide range of techniques and algorithms using ANNs in the context of artificial intelligence to build more intelligent machines. Connectionism presents a cognitive theory based on simultaneously occurring, distributed signal activity via connections that can be represented numerically, where learning occurs by modifying connection strengths based on experience.
Walter Harry Pitts, Jr. was a logician who worked in the field of computational neuroscience. He proposed landmark theoretical formulations of neural activity and generative processes that influenced diverse fields such as cognitive sciences and psychology, philosophy, neurosciences, computer science, artificial neural networks, cybernetics and artificial intelligence, together with what has come to be known as the generative sciences. He is best remembered for having written along with Warren McCulloch, a seminal paper in scientific history, titled "A Logical Calculus of Ideas Immanent in Nervous Activity" (1943). This paper proposed the first mathematical model of a neural network. The unit of this model, a simple formalized neuron, is still the standard of reference in the field of neural networks. It is often called a McCulloch–Pitts neuron. Prior to that paper, he formalized his ideas regarding the fundamental steps to building a Turing machine in "The Bulletin of Mathematical Biophysics" in an essay titled "Some observations on the simple neuron circuit".
ACT-R is a cognitive architecture mainly developed by John Robert Anderson and Christian Lebiere at Carnegie Mellon University. Like any cognitive architecture, ACT-R aims to define the basic and irreducible cognitive and perceptual operations that enable the human mind. In theory, each task that humans can perform should consist of a series of these discrete operations.
Situated cognition is a theory that posits that knowing is inseparable from doing by arguing that all knowledge is situated in activity bound to social, cultural and physical contexts.

Problem solving is the process of achieving a goal by overcoming obstacles, a frequent part of most activities. Problems in need of solutions range from simple personal tasks to complex issues in business and technical fields. The former is an example of simple problem solving (SPS) addressing one issue, whereas the latter is complex problem solving (CPS) with multiple interrelated obstacles. Another classification is into well-defined problems with specific obstacles and goals, and ill-defined problems in which the current situation is troublesome but it is not clear what kind of resolution to aim for. Similarly, one may distinguish formal or fact-based problems requiring psychometric intelligence, versus socio-emotional problems which depend on the changeable emotions of individuals or groups, such as tactful behavior, fashion, or gift choices.
Animat are artificial animals and is a contraction of animal and materials. The term includes physical robots and virtual simulations. The animat model includes features of a simple animal capable of interacting with its environment. It is, therefore, designed to simulate the ability to associate certain signals from the environment within a learning phase that indicate a potential for cognitive structure.
Computational cognition is the study of the computational basis of learning and inference by mathematical modeling, computer simulation, and behavioral experiments. In psychology, it is an approach which develops computational models based on experimental results. It seeks to understand the basis behind the human method of processing of information. Early on computational cognitive scientists sought to bring back and create a scientific form of Brentano's psychology.
John Robert Anderson is a Canadian-born American psychologist. He is currently professor of Psychology and Computer Science at Carnegie Mellon University.
Allan R. Wagner was an American experimental psychologist and learning theorist, whose work focused upon the basic determinants of associative learning and habituation. He co-authored the influential Rescorla–Wagner model of Pavlovian conditioning (1972) as well as the Standard Operating Procedures or "Sometimes Opponent Process" (SOP) theory of associative learning (1981), the Affective Extension of SOP and the Replaced Elements Model (REM) of configural representation. His research involved extensive study of the conditioned eyeblink response of the rabbit, of which he was one of the initial investigators (1964).
Protocol analysis is a psychological research method that elicits verbal reports from research participants. Protocol analysis is used to study thinking in cognitive psychology, cognitive science, and behavior analysis. It has found further application in the design of surveys and interviews, usability testing, educational psychology and design research.
Michael Lamport Commons is a theoretical behavioral scientist and a complex systems scientist. He developed the model of hierarchical complexity.

Computational creativity is a multidisciplinary endeavour that is located at the intersection of the fields of artificial intelligence, cognitive psychology, philosophy, and the arts.
Ron Sun is a cognitive scientist who made significant contributions to computational psychology and other areas of cognitive science and artificial intelligence. He is currently professor of cognitive sciences at Rensselaer Polytechnic Institute, and formerly the James C. Dowell Professor of Engineering and Professor of Computer Science at University of Missouri. He received his Ph.D. in 1992 from Brandeis University.
Conceptual change is the process whereby concepts and relationships between them change over the course of an individual person's lifetime or over the course of history. Research in four different fields – cognitive psychology, cognitive developmental psychology, science education, and history and philosophy of science - has sought to understand this process. Indeed, the convergence of these four fields, in their effort to understand how concepts change in content and organization, has led to the emergence of an interdisciplinary sub-field in its own right. This sub-field is referred to as "conceptual change" research.
Philip David Zelazo is a developmental psychologist and neuroscientist. His research has helped shape the field of developmental cognitive neuroscience regarding the development of executive function.
Robert S. Wyer Jr. is a visiting professor at the University of Cincinnati and professor (emeritus) at the University of Illinois, Urbana-Champaign. He received his doctoral degree from the University of Colorado. Wyer Jr.'s research interests cover various aspects of social information processing, including knowledge accessibility, comprehension, memory, social inference, the impact of affect on judgment and decisions, attitude formation and change, and consumer judgment and decision-making.
The theory of indispensable attributes (TIA) is a theory in the context of perceptual organisation which asks for the functional units and elementary features that are relevant for a perceptual system in the constitution of perceptual objects. Earlier versions of the theory emerged in the context of an application of research on vision to audition, and analogies between vision and audition were emphasised, whereas in more recent writings the necessity of a modality-general theory of perceptual organisation and objecthood is stressed.
