Self-model Theory Of Subjectivity
The self-model is the central concept in the theory of consciousness called the self-model theory of subjectivity (SMT). This concept comprises experiences of ownership, of first person perspective, and of a long-term unity of beliefs and attitudes. These features are instantiated in the prefrontal cortex. This theory is an interdisciplinary approach to understanding and explaining the phenomenology of consciousness and the self. This theory has two core contents, the phenomenal self-model (PSM) and the phenomenal model of the intentionality relation (PMIR). Thomas Metzinger advanced the theory in his 1993 book ''Subjekt und Selbstmodell'' (Subject and self-model). Overview of the PSM The PSM is an entity that "actually exists, not only as a distinct theoretical entity but something that will be empirically discovered in the future—for instance, as a specific stage of the global neural dynamics in the human brain". Involved in the PSM are three phenomenal properties that must occur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Consciousness
Consciousness, at its simplest, is awareness of a state or object, either internal to oneself or in one's external environment. However, its nature has led to millennia of analyses, explanations, and debate among philosophers, scientists, and theologians. Opinions differ about what exactly needs to be studied or even considered consciousness. In some explanations, it is synonymous with the mind, and at other times, an aspect of it. In the past, it was one's "inner life", the world of introspection, of private thought, imagination, and volition (psychology), volition. Today, it often includes any kind of cognition, experience, feeling, or perception. It may be awareness, awareness of awareness, metacognition, or self-awareness, either continuously changing or not. The disparate range of research, notions, and speculations raises a curiosity about whether the right questions are being asked. Examples of the range of descriptions, definitions or explanations are: ordered distinc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prefrontal Cortex
In mammalian brain anatomy, the prefrontal cortex (PFC) covers the front part of the frontal lobe of the cerebral cortex. It is the association cortex in the frontal lobe. The PFC contains the Brodmann areas BA8, BA9, BA10, BA11, BA12, BA13, BA14, BA24, BA25, BA32, BA44, BA45, BA46, and BA47. This brain region is involved in a wide range of higher-order cognitive functions, including speech formation (Broca's area), gaze ( frontal eye fields), working memory ( dorsolateral prefrontal cortex), and risk processing (e.g. ventromedial prefrontal cortex). The basic activity of this brain region is considered to be orchestration of thoughts and actions in accordance with internal goals. Many authors have indicated an integral link between a person's will to live, personality, and the functions of the prefrontal cortex. This brain region has been implicated in executive functions, such as planning, decision making, working memory, personality expression, moderating ...

Thomas Metzinger
Thomas Metzinger (; born 12 March 1958) is a German philosopher and Professor Emeritus of theoretical philosophy at the University of Mainz. His primary research areas include philosophy of mind, philosophy of neuroscience, and applied ethics, particularly focusing on neurotechnology, virtual reality, and artificial intelligence. He has argued in his book ''Being No One'' that the phenomenal self is a mental construct created by the brain. His 2024 book ''The Elephant and the Blind'' compiled extensive research on meditation. Academic career Metzinger studied philosophy, ethnology, and theology at Goethe University Frankfurt. He received his doctorate there in 1985, with a thesis on the mind-body problem. In 1992, he completed his habilitation at the University of Giessen. In 2000, Metzinger was appointed professor of philosophy of cognitive science at Osnabrück University, but moved to the University of Mainz in the same year. Metzinger cofounded in 1994 of the Assoc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parietal Lobe
The parietal lobe is one of the four Lobes of the brain, major lobes of the cerebral cortex in the brain of mammals. The parietal lobe is positioned above the temporal lobe and behind the frontal lobe and central sulcus. The parietal lobe integrates sensory information among various sensory modality, modalities, including spatial sense and navigation (proprioception), the main sensory receptive area for the sense of touch in the somatosensory cortex which is just posterior to the central sulcus in the postcentral gyrus, and the two-streams hypothesis#Dorsal stream, dorsal stream of the visual system. The major sensory inputs from the skin (mechanoreceptor, touch, thermoreceptor, temperature, and nociceptor, pain receptors), relay through the thalamus to the parietal lobe. Several areas of the parietal lobe are important in language processing in the brain, language processing. The somatosensory cortex can be illustrated as a distorted figure – the cortical homunculus (Latin: "li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Temporal Lobe
The temporal lobe is one of the four major lobes of the cerebral cortex in the brain of mammals. The temporal lobe is located beneath the lateral fissure on both cerebral hemispheres of the mammalian brain. The temporal lobe is involved in processing sensory input into derived meanings for the appropriate retention of visual memory, language comprehension, and emotion association. ''Temporal'' refers to the head's temples. Structure The temporal lobe consists of structures that are vital for declarative or long-term memory. Declarative (denotative) or explicit memory is conscious memory divided into semantic memory (facts) and episodic memory (events). The medial temporal lobe structures are critical for long-term memory, and include the hippocampal formation, perirhinal cortex, parahippocampal, and entorhinal neocortical regions. The hippocampus is critical for memory formation, and the surrounding medial temporal cortex is currently theorized to be critical f ...

Schizophrenia
Schizophrenia () is a mental disorder characterized variously by hallucinations (typically, Auditory hallucination#Schizophrenia, hearing voices), delusions, thought disorder, disorganized thinking and behavior, and Reduced affect display, flat or inappropriate affect. Symptoms Prodrome, develop gradually and typically begin during young adulthood and rarely resolve. There is no objective diagnostic test; diagnosis is based on observed behavior, a psychiatric history that includes the person's reported experiences, and reports of others familiar with the person. For a diagnosis of schizophrenia, the described symptoms need to have been present for at least six months (according to the DSM-5) or one month (according to the ICD-11). Many people with schizophrenia have other mental disorders, especially mood disorder, mood, anxiety disorder, anxiety, and substance use disorders, substance use disorders, as well as obsessive–compulsive disorder (OCD). About 0.3% to 0.7% of peo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autism
Autism, also known as autism spectrum disorder (ASD), is a neurodevelopmental disorder characterized by differences or difficulties in social communication and interaction, a preference for predictability and routine, sensory processing differences, focused interests, and repetitive behaviors, which may include stimming. Formal diagnosis requires significant challenges in multiple domains of life, with characteristics that are atypical or more pronounced than expected for one's age and sociocultural context.(World Health Organization: International Classification of Diseases version 11 (ICD-11)): https://icd.who.int/browse/2024-01/mms/en#437815624 Motor coordination difficulties are common but not required for diagnosis. Autism is a spectrum disorder, resulting in wide variations in presentation and support needs, such as that between speaking and non-speaking populations. Increased estimates of autism prevalence since the 1990s are primarily attributed to broader c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Depersonalization
Depersonalization is a dissociative phenomenon characterized by a subjective feeling of detachment from oneself, manifesting as a sense of disconnection from one's thoughts, emotions, sensations, or actions, and often accompanied by a feeling of observing oneself from an external perspective. Subjects perceive that the world has become vague, dreamlike, surreal, or strange, leading to a diminished sense of individuality or identity. Those affected often feel as though they are observing the world from a distance, as if separated by a barrier "behind glass". They maintain insight into the subjective nature of their experience, recognizing that it pertains to their own perception rather than altering objective reality. This distinction between subjective experience and objective reality distinguishes depersonalization from delusions, where individuals firmly believe in false perceptions as genuine truths. Depersonalization is also distinct from derealization, which involves a sense ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theory Of Mind
In psychology and philosophy, theory of mind (often abbreviated to ToM) refers to the capacity to understand other individuals by ascribing mental states to them. A theory of mind includes the understanding that others' beliefs, desires, intentions, emotions, and thoughts may be different from one's own. Possessing a functional theory of mind is crucial for success in everyday human social interactions. People utilize a theory of mind when analyzing, Value judgment, judging, and inferring other people's behaviors. Theory of mind was first conceptualized by researchers evaluating the presence of theory of mind in animals. Today, theory of mind research also investigates factors affecting theory of mind in humans, such as whether drug and alcohol consumption, language development, cognitive delays, age, and culture can affect a person's capacity to display theory of mind. It has been proposed that deficits in theory of mind may occur in people with autism, anorexia nervosa, schi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weak Central Coherence Theory
The weak central coherence theory (WCC), also called the central coherence theory (CC), suggests that a specific Perception, perceptual-Cognition, cognitive style, loosely described as a limited ability to understand context or to "see the big picture", underlies the central issue in autism and related autism spectrum disorder. Autism is a Neural development, neurodevelopmental disorder characterized by impaired social interaction and communication, repetitive behaviours, restricted interests, and sensory processing issues. Uta Frith of University College London first advanced the weak central coherence theory in the late 1980s. Frith surmised that autistic people typically think about things in the smallest possible parts. Her hypothesis is that autistic children actually perceive details better than non-autistic people, but "cannot see the wood for the trees." The weak central coherence theory attempts to explain how some autistic people can show remarkable ability in subjects li ...

Narcissism
Narcissism is a self-centered personality style characterized as having an excessive preoccupation with oneself and one's own needs, often at the expense of others. Narcissism, named after the Greek mythological figure ''Narcissus'', has evolved into a psychological concept studied extensively since the early 20th century, and it has been deemed highly relevant in various societal domains. Narcissism exists on a continuum that ranges from normal to abnormal personality expression. While many psychologists believe that a moderate degree of narcissism is healthy narcissism, normal and healthy in humans, there are also more extreme forms, observable particularly in people who have a personality condition like narcissistic personality disorder (NPD), where one's narcissistic qualities become pathological, leading to functional impairment and psychosocial disability. It has also been discussed in dark triad studies, along with subclinical psychopathy and Machiavellianism (psychology ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cognitive Modeling
A cognitive model is a representation of one or more cognitive processes in humans or other animals for the purposes of comprehension and prediction. There are many types of cognitive models, and they can range from box-and-arrow diagrams to a set of equations to software programs that interact with the same tools that humans use to complete tasks (e.g., computer mouse and keyboard). In terms of information processing, cognitive modeling is modeling of human perception, reasoning, memory and action. Relationship to cognitive architectures Cognitive models can be developed within or without a cognitive architecture, though the two are not always easily distinguishable. In contrast to cognitive architectures, cognitive models tend to be focused on a single cognitive phenomenon or process (e.g., list learning), how two or more processes interact (e.g., visual search and decision making), or making behavioral predictions for a specific task or tool (e.g., how instituting a new softw ...
