Mental representation in the context of Cognitive map

In natural language and physical science, a physical object or material object (or simply an object or body) is a contiguous collection of matter, within a defined boundary (or surface), that exists in space and time. Usually contrasted with abstract objects and mental objects.

Also in common usage, an object is not constrained to consist of the same collection of matter. Atoms or parts of an object may change over time. An object is usually meant to be defined by the simplest representation of the boundary consistent with the observations. However the laws of physics only apply directly to objects that consist of the same collection of matter.

In philosophy and in common usage, an idea (from the Greek word: ἰδέα (idea), meaning 'a form, or a pattern') is the result of thought. Also in philosophy, ideas can also be mental representational images of some object. Many philosophers have considered ideas to be a fundamental ontological category of being. The capacity to create and understand the meaning of ideas is considered to be an essential and defining feature of human beings.

An idea arises in a reflexive, spontaneous manner, even without thinking or serious reflection, for example, when we talk about the idea of a person or a place. A new or an original idea can often lead to innovation. Our actions are based upon beliefs, beliefs are patterns or organized sets of ideas.

Introspection is the examination of one's own conscious thoughts and feelings. In psychology, the process of introspection relies on the observation of one's mental state, while in a spiritual context it may refer to the examination of one's soul. Introspection is closely related to human self-reflection and self-discovery and is contrasted with external observation.

It generally provides a privileged access to one's own mental states, not mediated by other sources of knowledge, so that individual experience of the mind is unique. Introspection can determine any number of mental states including: sensory, bodily, cognitive, emotional and so forth.

The language of thought hypothesis (LOTH), sometimes known as thought ordered mental expression (TOME), is a view in linguistics, philosophy of mind and cognitive science, put forward by American philosopher Jerry Fodor. It describes the nature of thought as possessing "language-like" or compositional structure (sometimes known as mentalese). On this view, simple concepts combine in systematic ways (akin to the rules of grammar in language) to build thoughts. In its most basic form, the theory states that thought, like language, has syntax.

Using empirical evidence drawn from linguistics and cognitive science to describe mental representation from a philosophical vantage-point, the hypothesis states that thinking takes place in a language of thought (LOT): cognition and cognitive processes are only 'remotely plausible' when expressed as a system of representations that is "tokened" by a linguistic or semantic structure and operated upon by means of a combinatorial syntax. Linguistic tokens used in mental language describe elementary concepts which are operated upon by logical rules establishing causal connections to allow for complex thought. Syntax as well as semantics have a causal effect on the properties of this system of mental representations.

A mental model is an internal representation of external reality: that is, a way of representing reality within the mind. Such models are hypothesized to play a major role in cognition, reasoning and decision-making. The term for this concept was coined in 1943 by Kenneth Craik, who suggested that the mind constructs "small-scale models" of reality that it uses to anticipate events. Mental models can help shape behaviour, including approaches to solving problems and performing tasks.

In psychology, the term mental models is sometimes used to refer to mental representations or mental simulation generally. The concepts of schema and conceptual models are cognitively adjacent. Elsewhere, it is used to refer to the "mental model" theory of reasoning developed by Philip Johnson-Laird and Ruth M. J. Byrne.

Eleanor Rosch (once known as Eleanor Rosch Heider; born 9 July 1938) is an American psychologist. She is a professor of psychology at the University of California, Berkeley, specializing in cognitive psychology and primarily known for her work on categorization, in particular her prototype theory, which has profoundly influenced the field of cognitive psychology.

Throughout her work Rosch has conducted extensive research focusing on a range of topics, including semantic categorization, mental representation of concepts, and linguistics. Her research interests include cognition, concepts, causality, thinking, memory, and cross-cultural, and Eastern and religious psychology. Her more recent work in the psychology of religion has sought to show the implications of Buddhism and contemplative aspects of Western religions for modern psychology.

The term "direction of fit" is used in the philosophy of intentionality to distinguish between types of representations. It is commonly applied in two related senses: first, to distinguish the mental states of belief and desire; and second, to distinguish between types of linguistic utterances, such as indicative and imperative sentences.

First, philosophers of mind distinguish between mind-to-world (i.e., mind-to-fit-world) and world-to-mind (i.e., world-to-fit-mind) directions of fit. In the former, mental states such as beliefs are subject to updates in order to fit evidence provided by the world (the mind changes to fit the world, thus beliefs have a mind-to-world direction of fit). In the latter, mental states such as desires motivate the agent to change the world in order to fit the desired state in the mind (the world changes to fit the mind, thus desires have a world-to-mind direction of fit).

In formal linguistics, discourse representation theory (DRT) is a framework for exploring meaning under a formal semantics approach. One of the main differences between DRT-style approaches and traditional Montagovian approaches is that DRT includes a level of abstract mental representations (discourse representation structures, DRS) within its formalism, which gives it an intrinsic ability to handle meaning across sentence boundaries. DRT was created by Hans Kamp in 1981. A very similar theory was developed independently by Irene Heim in 1982, under the name of File Change Semantics (FCS). Discourse representation theories have been used to implement semantic parsers and natural language understanding systems.

In the social sciences, framing is a set of concepts and theoretical perspectives on how individuals, groups, and societies organize, perceive, and communicate about reality. Framing can manifest in thought or interpersonal communication. Frames in thought consist of the mental representations, interpretations, and simplifications of reality. Frames in communication consist of the communication of frames between different actors. Framing is a key component of sociology, the study of social interaction among humans. Framing is an integral part of conveying and processing data daily. Successful framing techniques can be used to reduce the ambiguity of intangible topics by contextualizing the information in such a way that recipients can connect to what they already know. Framing is mistaken in the world outside of communication as bias, or arguments around nature vs nurture. While biases and how a person is raised might add to stereotypes or anecdotes gathered, those are just possible cultural and biological influences within the set of concepts that is framing.

In social theory, framing is a schema of interpretation, a collection of anecdotes and stereotypes, that individuals rely on to understand and respond to events. In other words, people build a series of mental "filters" through biological and cultural influences. They then use these filters to make sense of the world. The choices they then make are influenced by their creation of a frame. Framing involves social construction of a social phenomenon – by mass media sources, political or social movements, political leaders, or other actors and organizations. Participation in a language community necessarily influences an individual's perception of the meanings attributed to words or phrases. Politically, the language communities of advertising, religion, and mass media are highly contested, whereas framing in less-sharply defended language communities might evolve imperceptibly and organically over cultural time frames, with fewer overt modes of disputation.

The ideomotor phenomenon is a psychological phenomenon wherein a subject makes motions unconsciously. Also called ideomotor response (or ideomotor reflex) and abbreviated to IMR, it is a concept in hypnosis and psychological research. It is derived from the terms "ideo" (idea, or mental representation) and "motor" (muscular action). The phrase is most commonly used in reference to the process whereby a thought or mental image brings about a seemingly "reflexive" or automatic muscular reaction, often of minuscule degree, and potentially outside of the awareness of the subject. As in responses to pain, the body sometimes reacts reflexively with an ideomotor effect to ideas alone without the person consciously deciding to take action. The effects of automatic writing, dowsing, facilitated communication, applied kinesiology, and ouija boards have been attributed to the phenomenon.

The associated term "ideo-dynamic response" (or "reflex") applies to a wider domain, and extends to the description of all bodily reactions (including ideo-motor and ideo-sensory responses) caused in a similar manner by certain ideas, e.g., the salivation often caused by imagining sucking a lemon, which is a secretory response. The notion of an ideo-dynamic response contributed to James Braid's first neuropsychological explanation of the principle through which suggestion operated in hypnotism.

Similarity refers to the psychological degree of identity of two mental representations. It is fundamental to human cognition since it provides the basis for categorization of entities into kinds and for various other cognitive processes. It underpins our ability to interact with unknown entities by predicting how they will behave based on their similarity to entities we are familiar with. Research in cognitive psychology has taken a number of approaches to the concept of similarity. Each of them is related to a particular set of assumptions about knowledge representation.
