Mind and Mentality

1. Access consciousness – The availability of information for direct control of reasoning and behavior. It differs from phenomenal consciousness (raw experience).
2. Anomalous monism – A philosophical theory that mental events are identical to physical events but are not governed by strict physical laws. It reconciles materialism with the intuition that mental states cause behavior.
3. Antirepresentationalism – The view that mental states do not fundamentally work by representing the world. Instead, cognition is seen as embodied action.
4. Apperception – The process by which new experience is assimilated into the existing structure of consciousness. It goes beyond simple perception to include self-awareness and reflection.
5. Artificial general intelligence (AGI) – A hypothetical machine capable of understanding, learning, and applying intelligence across any domain. It is distinct from narrow AI, which excels at only one task.
6. Attention schema theory – The proposal that consciousness is a simplified model the brain constructs to control attention. It argues that we experience awareness because the brain models its own attentional processes.
7. Automaticity of mind – The capacity for cognitive processes to occur without conscious intention or effort. Most everyday actions (e.g., driving a familiar route) are governed by automatic mental routines.
8. Autonoetic consciousness – The ability to mentally travel backward and forward in subjective time. It allows one to re-experience past events and pre-experience future ones.
9. Availability cascade – A self-reinforcing mental process where a shared belief gains plausibility through its increasing repetition. The more a thought is publicly discussed, the more true it appears.
10. Bicameral mentality – A controversial hypothesis that ancient humans experienced commands from one brain hemisphere as auditory hallucinations (gods). It suggests that modern consciousness emerged relatively recently in history.
11. Binding problem – The challenge of explaining how separate neural processes produce a unified, coherent perceptual experience. For example, how color, motion, and shape combine into a single object.
12. Blindsight (further mental aspect) – A condition where brain-damaged patients respond to visual stimuli without conscious seeing. It reveals a dissociation between mental processing and phenomenal awareness.
13. Brain in a vat – A thought experiment questioning whether one can know the external world is real. If a brain is fed simulated experiences, its mental states would be indistinguishable from genuine ones.
14. Cartesian theater – A pejorative term for the idea of a central place in the brain where “everything comes together” for conscious observation. Dennett argues this is a misleading way to understand mentality.
15. Causal role functionalism – The view that mental states are defined by their causal relations to sensory inputs, other mental states, and behavioral outputs. What matters is the role, not the physical substrate.
16. Cerebral achromatopsia – A condition caused by brain damage that eliminates color experience while leaving form and motion perception intact. It demonstrates that color qualia are neurologically separable.
17. Chinese room argument – Searle’s thought experiment against strong AI: a person following rules can simulate understanding without any genuine comprehension. It challenges the idea that syntax alone produces semantics.
18. Church–Turing thesis – The principle that any effectively computable function can be computed by a Turing machine. It sets limits on what can be achieved by computational models of mind.
19. Cogito ergo sum – Descartes’ foundational statement: “I think, therefore I am.” It treats the act of thinking as the only indubitable evidence of one’s existence.
20. Cognitive closure – The idea that some truths are permanently inaccessible to the human mind due to our evolved cognitive limits. Certain aspects of reality may be unknowable, just as quantum mechanics is to a mouse.
21. Cognitive penetrability – The degree to which perceptual experiences can be influenced by beliefs, desires, or expectations. If seeing a face as threatening changes with a new belief, perception is cognitively penetrable.
22. Computational theory of mind – The view that the mind is a computation system operating over internal representations. Thoughts are seen as symbolic manipulations akin to software running on neural hardware.
23. Conceptual engineering – The deliberate revision or replacement of existing mental concepts. Philosophers might propose improving the concept of “free will” or “knowledge” for better practical use.
24. Connectionism – A model of cognition using artificial neural networks with distributed representations. It contrasts with classical symbolic AI by emphasizing learning through weight adjustments.
25. Consciousness meter – A hypothetical device that could objectively measure the presence and level of conscious awareness. Its possibility is debated in the science of consciousness.
26. Content externalism – The view that the contents of one’s thoughts depend partly on the external environment. For example, “water” in your head means H₂O only because you live on Earth, not Twin Earth.
27. Contrastive analysis – A method comparing closely matched conscious and unconscious mental processes. By holding stimuli constant, researchers can identify the neural correlates of awareness.
28. Creativity of mind – The uniquely human ability to generate novel, valuable, and surprising ideas. It involves combining existing mental representations in non-routine ways.
29. Dark consciousness – A hypothetical form of consciousness that is entirely unlike human experience (e.g., alien, machine, or drug-induced). It challenges the assumption that all minds share familiar qualia.
30. Déjà vécu – A more intense form of déjà vu involving the strong feeling of having lived through the entire present moment before. It often occurs in temporal lobe epilepsy.
31. Diachronic unity – The unity of consciousness across time, making you feel like the same self who had past experiences. It binds yesterday’s thoughts to today’s.
32. Disjunctivism – A theory of perception arguing that veridical perception and hallucination are fundamentally different kinds of mental states. Rejecting the “common kind” assumption changes how we analyze experience.
33. Dual-aspect theory – The view that mind and matter are two aspects of the same underlying reality. It avoids both materialism and substance dualism.
34. Ego dissolution – The loss of the sense of a separate self, often reported under psychedelics or deep meditation. The boundary between self and world temporarily vanishes.
35. Eliminative materialism – The radical view that common-sense mental concepts (beliefs, desires) are false and will be replaced by neuroscience. Just as we abandoned “phlogiston,” we may abandon “pain” as a real category.
36. Emergentism – The idea that mental properties arise from physical systems but are not reducible to them. Consciousness emerges when matter reaches a certain complexity.
37. Epiphenomenalism – The view that mental states are caused by physical events but have no causal power themselves. Consciousness is a mere “side effect” like the steam whistle of a train.
38. Epistemic gap – The explanatory gap between physical facts and subjective experience. No matter how much we know about brain processes, we cannot deduce what it is like to be that brain.
39. Eternal recurrence (mental aspect) – Nietzsche’s thought experiment of living one’s life over and over. It functions as a mental test of whether one truly affirms existence.
40. Everyday mind-wandering – The spontaneous shift of attention away from the present task toward internal thoughts. It occupies up to 50% of waking mental life.
41. Exocortex – An external, artificial cognitive extension of one’s mind (e.g., a smartphone or wearable AI). It functions as a prosthetic memory or reasoning system.
42. Experiential blindness – The inability to imagine or comprehend a specific type of conscious experience one has never had. A person born blind cannot mentally simulate color qualia.
43. Explanatory gap – Levine’s term for the difficulty of explaining qualia in physical terms. We can correlate brain activity with pain, but why should that activity feel like anything?
44. Extended mind thesis – The claim that mental processes can extend beyond the skull into the environment. A notebook or smartphone can literally become part of one’s memory system.
45. External memory – Information stored outside the brain (notes, photos, digital files) that functions as genuine memory. It raises questions about where the mind ends and the world begins.
46. First-person perspective – The subjective, private point of view from which one experiences the world. It is the hallmark of conscious mentality.
47. Folk psychology – The common-sense set of mental concepts (belief, desire, intention) used to predict and explain behavior. It works well for everyday life but may not map onto neural reality.
48. Frame problem – The challenge of representing the implicit effects of an action in an artificial intelligence. How does a mind know which aspects of the world stay the same and which change?
49. Freudian unconscious (revisited for mentality) – The dynamic, repressed region of mind containing wishes and memories actively kept from awareness. It differs from the merely “non-conscious” (e.g., heart rate regulation).
50. Fringe consciousness – The vague, peripheral awareness that accompanies focal attention (e.g., a sense of familiarity or time passing). William James described it as the “transitive parts” of the stream of thought.
51. Global workspace theory – A model where consciousness is a global “blackboard” that broadcasts information to many specialized modules. Information becomes conscious when it gains access to this workspace.
52. Gödelian argument – The claim that human minds can see the truth of Gödel statements that formal systems cannot prove. It is used to argue against mechanism (that minds are computers).
53. Hard problem of consciousness – Chalmers’ term for explaining why and how physical processes give rise to subjective experience. Unlike “easy problems” (behavior, discrimination), the hard problem resists functional explanation.
54. Heterophenomenology – Dennett’s method of taking first-person reports as data while remaining agnostic about their truth. It treats “how it seems” as a verbal report, not a direct window into consciousness.
55. Higher-order thought theory – The view that a mental state becomes conscious only when one has a higher-order thought about that state. You feel pain because you think “I am in pain.”
56. Hypertime – An imaginary second dimension of time used to model changes in time itself. It is a mental construct for philosophical debates about temporal passage.
57. Ideasthesia – A phenomenon where concepts induce sensory-like experiences (e.g., seeing the number 7 as “angry”). It suggests that many “synesthesias” are actually concept-mediated.
58. Illusionism – The radical claim that phenomenal consciousness is an illusion; we only think we have qualia. It denies the existence of the very thing the hard problem tries to explain.
59. Imagery rescripting – A mental technique where one deliberately changes the content of a distressing mental image. It is used therapeutically to transform traumatic memories.
60. Imagination inflation – The tendency for vividly imagining an event to increase confidence that it actually occurred. This mental phenomenon can create false memories.
61. Immanent cognition – Knowledge that does not require a representational intermediary. Some medieval philosophers argued that the mind knows itself directly, not through mental images.
62. Inattentional blindness (mental frame) – The failure to notice a fully visible object because attention is elsewhere. It demonstrates the severe limits of conscious perception.
63. Incommensurability – A problem in comparing two radically different conceptual schemes or mental frameworks. Paradigm shifts in science can make old and new theories untranslatable.
64. Indeterminacy of translation – Quine’s thesis that multiple, equally correct manuals of translation exist for a foreign language. It raises doubts about the existence of fixed mental meanings.
65. Inner speech – The silent, verbal thinking that accompanies much conscious thought. It is a form of mental activity that retains many properties of external speech.
66. Intentional inexistence – The property of mental states being directed toward objects that may not exist. You can think of a unicorn even though unicorns are not real.
67. Intentionality – The “aboutness” of mental states—beliefs are about things, desires for things. It is the hallmark of the mental, distinguishing thoughts from mere physical objects.
68. Interactive dualism – Descartes’ view that mind (nonphysical) and body (physical) causally interact, primarily via the pineal gland. It faces the problem of how two radically different substances can influence each other.
69. Intermediate consciousness – States of reduced but present awareness, such as drowsiness or hypnotic trance. They fall between full wakefulness and unconsciousness.
70. Internal monologue – The continuous, inner narrative that many people experience as their “voice of consciousness.” It is one form of inner speech but not universal across all humans.
71. Intersubjectivity – The shared, mutual understanding between conscious minds. It is the basis for empathy, language, and social reality.
72. Introspective illusion – The mistaken belief that one has direct, accurate access to one’s own mental processes. Nisbett and Wilson argued that people often confabulate reasons for their choices.
73. Intuition pump – A thought experiment designed to evoke a strong intuitive judgment (e.g., the Chinese Room). It is a rhetorical tool in philosophy of mind.
74. Inverted spectrum – A thought experiment where two people have opposite color experiences but behave identically. If your “red” is my “green,” is there any way to tell?
75. Jamesian stream of thought – William James’ description of consciousness as a continuous, flowing “river” rather than discrete units. It emphasizes the temporal continuity of mental life.
76. Joint attention – The shared focus of two minds on the same object, with mutual awareness of the sharing. It is a foundational mental capacity for social cognition.
77. Knowledge argument – Frank Jackson’s “Mary’s room” thought experiment: Mary knows all physical facts about color but learns something new when she sees red. It argues that qualia are non-physical.
78. Language of thought hypothesis – The idea that thinking occurs in an internal, mental language (“Mentalese”). Mental representations have a syntactic and semantic structure like a natural language.
79. Laws of thought – Traditional logical principles (identity, non-contradiction, excluded middle) that govern rational mental processes. They are often violated in everyday human reasoning.
80. Libet’s half-second delay – The finding that brain activity precedes conscious intention to act by several hundred milliseconds. It raises profound questions about free will and the timing of conscious decisions.
81. Linguistic relativity – The hypothesis that language shapes habitual thought patterns. Speakers of different languages may have different mental worlds.
82. Localization of function – The mapping of specific mental abilities to specific brain regions. Phineas Gage’s personality change after frontal lobe damage was an early clue.
83. Malleable self – The observation that one’s sense of identity shifts with context, mood, and social role. The “self” is not a fixed mental entity.
84. Marr’s three levels – A framework for analyzing mental systems: computational (what task), algorithmic (how procedure), and implementational (physical hardware). It separates function from mechanism.
85. Materialism – The view that only physical matter exists; mind is either identical to or emerges from brain processes. It is the dominant stance in contemporary neuroscience.
86. Mathy mind – A colloquial term for a cognitive style that processes the world in terms of patterns, numbers, and formal relations. It contrasts with verbal or narrative thinking.
87. Meat machine – A dismissive term for the view that humans are just biological machines. It is often used in debates about whether materialism reduces human dignity.
88. Memory color – The phenomenon where knowledge of an object’s typical color influences perceived color. A banana looks yellow even in blue light because the mind “fills in.”
89. Mental causation – The ability of mental states (desires, beliefs) to cause physical actions. It is a central problem for dualism and epiphenomenalism.
90. Mental chronometry – The measurement of the time course of mental processes using reaction times. It infers the duration of stages like perception, decision, and response.
91. Mental continuity thesis – The claim that human minds differ in degree, not kind, from animal minds. It opposes the idea of a sharp cognitive Rubicon.
92. Mental filing system – A metaphor for long-term memory organization involving categories, hierarchies, and cross-references. It is more structured than a simple “storehouse.”
93. Mental image – A quasi-pictorial representation in the mind, such as visualizing a triangle. Debates continue over whether images are depictive or propositional.
94. Mental model – An internal representation of a real or imagined situation. You use mental models to simulate, predict, and reason about how things work.
95. Mental number line – The spatial representation of numbers in the mind, typically with smaller numbers left and larger numbers right. It can be distorted in various cultures.
96. Mental paint – A metaphor for raw, non-representational sensory qualities. Some philosophers argue that pure qualia (like “redness”) exist before any interpretation.
97. Mental physics – The intuitive understanding of physical objects (e.g., that unsupported objects fall). It is a form of naive, built-in knowledge.
98. Mental rehearsal – Practicing a skill in imagination without physical movement. It improves performance nearly as much as actual practice.
99. Mental rotation – The cognitive ability to rotate a two- or three-dimensional object in the imagination. Response time increases linearly with rotation angle.
100. Mental twin – A thought experiment where two identical physical brains have identical mental states. It tests theories of consciousness and externalism.
101. Mereological fallacy – Attributing psychological predicates (e.g., “believes”) to the brain rather than the whole person. It is an error to say “my hippocampus remembers” instead of “I remember.”
102. Meta-cognitive blindness – The inability to accurately assess one’s own cognitive strengths and weaknesses. Most people rate themselves as “above average” in multiple domains.
103. Meta-desire – A desire about a desire (e.g., wanting to stop wanting to smoke). It plays a role in self-control and addiction recovery.
104. Meta-emotion – An emotion about another emotion (e.g., feeling ashamed of being angry). It is a second-order mental state.
105. Metacognitive monitoring – The process of observing and evaluating one’s own cognitive states. For example, feeling that you “don’t know” an answer is a metacognitive judgment.
106. Metaphysical subject – The pure “I” that has experiences but has no properties of its own. In some philosophies, it is the ultimate ground of mentality.
107. Microgenesis – The development of a mental act in very brief time scales (milliseconds to seconds). It traces how a percept or thought unfolds from inception to completion.
108. Mimetic mind – A pre-linguistic form of cognition based on imitation, gesture, and ritual. It is hypothesized to have preceded language in human evolution.
109. Mind-body problem – The enduring philosophical question of how mental states relate to physical states. It includes subproblems of consciousness, intentionality, and mental causation.
110. Mind-blindness – The inability to attribute mental states to oneself or others, characteristic of autism. It is a deficit in theory of mind.
111. Mind-brain identity theory – The claim that mental states are literally identical to brain states (e.g., pain = C-fiber firing). It is a strong form of materialism.
112. Mind-dust – A whimsical term for a hypothetical primitive form of consciousness in fundamental particles. Panpsychism suggests that mind-dust aggregates into larger minds.
113. Mind-forg’d manacles – William Blake’s phrase for self-imposed mental constraints (e.g., irrational beliefs). It highlights how the mind can imprison itself.
114. Mind-print – A hypothetical unique pattern of a person’s mental functioning, analogous to a fingerprint. It could serve as an identifier.
115. Mind-reading – The everyday ability to infer the mental states of others. It is not paranormal but a standard social cognitive skill.
116. Mind-wandering – The spontaneous shift of attention from a task to internal thoughts. It is associated with both creativity and unhappiness.
117. Minimal phenomenal experience – The simplest possible conscious state, stripped of content, self, and time. Some meditative states approach this boundary.
118. Modularity of mind – The view that the mind consists of specialized, domain-specific modules (e.g., face recognition, language). Fodor argued that modules are “encapsulated” and fast.
119. Multiple drafts model – Dennett’s alternative to the Cartesian theater: consciousness is a parallel, distributed process with no single “finish line.” There is no moment of “becoming conscious.”
120. Mutual knowledge – A state where two people both know something and each knows the other knows. It is the foundation of common ground in conversation.
121. Narrative identity – The internal, evolving story a person constructs about their life. It integrates past, present, and future into a coherent self.
122. Necessary being (mental concept) – An idea that cannot fail to exist in the mind, such as the concept of a perfect triangle. It contrasts with contingent mental objects.
123. Neural correlate of consciousness (NCC) – The minimal set of neural activity sufficient for a specific conscious experience. Finding the NCC is the central project of consciousness science.
124. Neurophenomenology – A research approach that combines first-person reports with third-person neural data. It aims to bridge subjective experience and objective measurement.
125. Neuroplasticity (mental angle) – The brain’s lifelong ability to reorganize mental maps in response to experience. London taxi drivers have enlarged hippocampi from spatial memory.
126. Nomic correlate – A property that is lawfully connected to consciousness across all possible worlds. It differs from a merely contingent neural correlate.
127. Non-conceptual content – Mental content that does not depend on the possession of concepts. A baby or animal can perceive red without having the concept RED.
128. Numinal mind – A term for the mind considered as a noumenon (thing-in-itself), not as it appears to introspection. Kant argued we can never know the mind as it truly is.
129. Objective self-awareness – A state where attention is directed toward the self as an object. Standing before a mirror or camera often triggers this.
130. Olfactory consciousness – The rarely studied subjective experience of smell. It is less verbally coded than vision or audition.
131. Ontological subjectivity – The essential property of conscious states: they exist only for a subject. A pain cannot exist unexperienced.
132. Open individualism – The view that all conscious beings are the same single subject, just experiencing different lives. It dissolves the problem of personal identity.
133. Ordinary language philosophy – A method that examines everyday mental terms to dissolve philosophical puzzles. “Knowing,” “thinking,” and “intending” are studied in use.

192. Self-schema – A cognitive structure organizing knowledge about oneself. It guides attention, memory, and interpretation of self-relevant information.
193. Self-specifying – The property of a mental state that identifies its own subject (e.g., “I am in pain” implicitly knows the “I”). It avoids an infinite regress.
194. Self-verification – The motive to have others see us as we see ourselves, even if negatively. It can override the motive for self-enhancement.
195. Sensorimotor contingency theory – The view that perception is not a representation but mastery of laws linking action and sensation. Seeing is knowing what you will see if you move.
196. Shifting mental energy – The phenomenological experience of moving attention from one thought to another. It feels effortful, though the physics is unknown.
197. Simulation theory – The claim that we understand others’ minds by mentally simulating their situation. We use our own mind as a model.
198. Situated cognition – The idea that mental processes are embedded in, and shaped by, real-world contexts. The environment is part of the cognitive system.
