Mental model in the context of Conceptual model

In psychology and cognitive science, a schema (pl.: schemata or schemas) describes a pattern of thought or behavior that organizes categories of information and the relationships among them. It can also be described as a mental structure of preconceived ideas, a framework representing some aspect of the world, or a system of organizing and perceiving new information, such as a mental schema or conceptual model. Schemata influence attention and the absorption of new knowledge: people are more likely to notice things that fit into their schema, while re-interpreting contradictions to the schema as exceptions or distorting them to fit. Schemata have a tendency to remain unchanged, even in the face of contradictory information. Schemata can help in understanding the world and the rapidly changing environment. People can organize new perceptions into schemata quickly as most situations do not require complex thought when using schema, since automatic thought is all that is required.

People use schemata to organize current knowledge and provide a framework for future understanding. Examples of schemata include mental models, social schemas, stereotypes, social roles, scripts, worldviews, heuristics, and archetypes. In Piaget's theory of development, children construct a series of schemata, based on the interactions they experience, to help them understand the world.

The visual system is the physiological basis of visual perception (the ability to detect and process light). The system detects, transduces and interprets information concerning light within the visible range to construct an image and build a mental model of the surrounding environment. The visual system is associated with the eye and functionally divided into the optical system (including cornea and lens) and the neural system (including the retina and visual cortex).

The visual system performs a number of complex tasks based on the image forming functionality of the eye, including the formation of monocular images, the neural mechanisms underlying stereopsis and assessment of distances to (depth perception) and between objects, motion perception, pattern recognition, accurate motor coordination under visual guidance, and colour vision. Together, these facilitate higher order tasks, such as object identification. The neuropsychological side of visual information processing is known as visual perception, an abnormality of which is called visual impairment, and a complete absence of which is called blindness. The visual system also has several non-image forming visual functions, independent of visual perception, including the pupillary light reflex and circadian photoentrainment.

In psychology, apprehension (Lat. ad, "to"; prehendere, "to seize") is a term applied to a model of consciousness in which nothing is affirmed or denied of the object in question, but the mind is merely aware of ("seizes") it.

"Judgment" (says Reid, ed. Hamilton, i. p. 414) "is an act of the mind, specifically different from simple apprehension or the bare conception of a thing". "Simple apprehension or conception can neither be true nor false." This distinction provides for the large class of mental acts in which we are simply aware of, or "take in" a number of familiar objects, about which we in general make no judgment, unless our attention is suddenly called by a new feature. Or again, two alternatives may be apprehended without any resultant judgment as to their respective merits.

In neuroscience, predictive coding (also known as predictive processing) is a theory of brain function which postulates that the brain is constantly generating and updating a "mental model" of the environment. According to the theory, such a mental model is used to predict input signals from the senses that are then compared with the actual input signals from those senses. Predictive coding is member of a wider set of theories that follow the Bayesian brain hypothesis.

The Princeton University Department of Psychology, located in Peretsman-Scully Hall, is an academic department of Princeton University in Princeton, New Jersey. It has been home to psychologists who have made significant scientific discoveries in psychology and neuroscience, such as adult neurogenesis in primate brains, the concept of the cognitive miser, bystander non-intervention, face-selective neurons in primate brains, feature integration theory, mental models theory, and prospect theory.

The department's large undergraduate and graduate programs are highly ranked and it has developed a well-respected neuroscience program. The faculty have received numerous awards, including a Nobel Prize, six Distinguished Contributions awards from the American Psychological Association, and three William James Fellow awards from the Association for Psychological Science (APS). Additionally, faculty members have previously served as presidents of the APS, are fellows of the APS, and have been inducted into the National Academy of Sciences. As of 2024, the department is chaired by Casey Lew-Williams, a developmental psychologist known for his work on communication in human infancy.
