Self Awareness
In philosophy, self-awareness is the awareness and reflection of one's own personality or individuality, including traits, feelings, and behaviors. It is not to be confused with consciousness in the sense of qualia. While consciousness is being aware of one's body and environment, self-awareness is the recognition of that consciousness. Self-awareness is how an individual experiences and understands their own character, feelings, motives, and desires. Biology Mirror neurons Researchers are investigating which part of the brain allows people to be self-aware and how people are biologically programmed to be self-aware. V.S. Ramachandran speculates that mirror neurons may provide the neurological basis of human self-awareness. In an essay written for Edge.org in 2009, Ramachandran gave the following explanation of his theory: " ese neurons can not only help simulate other people's behavior but can be turned 'inward'—as it were—to create second-order representations o ...

Proprioception
Proprioception ( ) is the sense of self-movement, force, and body position. Proprioception is mediated by proprioceptors, a type of sensory receptor, located within muscles, tendons, and joints. Most animals possess multiple subtypes of proprioceptors, which detect distinct kinesthetic parameters, such as joint position, movement, and load. Although all mobile animals possess proprioceptors, the structure of the sensory organs can vary across species. Proprioceptive signals are transmitted to the central nervous system, where they are integrated with information from other Sensory nervous system, sensory systems, such as Visual perception, the visual system and the vestibular system, to create an overall representation of body position, movement, and acceleration. In many animals, sensory feedback from proprioceptors is essential for stabilizing body posture and coordinating body movement.

Cognitive Processing Speed
Mental chronometry is the scientific study of processing speed or reaction time on cognitive tasks to infer the content, duration, and temporal sequencing of mental operations. Reaction time (RT; also referred to as "response time") is measured by the elapsed time between stimulus onset and an individual's response on elementary cognitive tasks (ECTs), which are relatively simple perceptual-motor tasks typically administered in a laboratory setting. Mental chronometry is one of the core methodological paradigms of human experimental psychology, experimental, cognitive psychology, cognitive, and differential psychology, but is also commonly analyzed in Physiological psychology, psychophysiology, cognitive neuroscience, and behavioral neuroscience to help elucidate the biological mechanisms underlying perception, attention, and decision-making in humans and other species. Mental chronometry uses measurements of elapsed time between sensory stimulus onsets and subsequent behavioral ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Working Memory
Working memory is a cognitive system with a limited capacity that can Memory, hold information temporarily. It is important for reasoning and the guidance of decision-making and behavior. Working memory is often used synonymously with short-term memory, but some theorists consider the two forms of memory distinct, assuming that working memory allows for the manipulation of stored information, whereas short-term memory only refers to the short-term storage of information. Working memory is a theoretical concept central to cognitive psychology, neuropsychology, and neuroscience. History The term "working memory" was coined by George Armitage Miller, Miller, Eugene Galanter, Galanter, and Karl H. Pribram, Pribram, and was used in the 1960s in the context of Computational theory of mind, theories that likened the mind to a computer. In 1968, Atkinson–Shiffrin memory model, Atkinson and Shiffrin used the term to describe their "short-term store". The term short-term store was the na ...

Intelligence
Intelligence has been defined in many ways: the capacity for abstraction, logic, understanding, self-awareness, learning, emotional knowledge, reasoning, planning, creativity, critical thinking, and problem-solving. It can be described as the ability to perceive or infer information and to retain it as knowledge to be applied to adaptive behaviors within an environment or context. The term rose to prominence during the early 1900s. Most psychologists believe that intelligence can be divided into various domains or competencies. Intelligence has been long-studied in humans, and across numerous disciplines. It has also been observed in the cognition of non-human animals. Some researchers have suggested that plants exhibit forms of intelligence, though this remains controversial. Etymology The word '' intelligence'' derives from the Latin nouns '' intelligentia'' or '' intellēctus'', which in turn stem from the verb '' intelligere'', to comprehend or perceive. In the M ...

Neo-Piagetian Theories Of Cognitive Development
Neo-Piagetian theories of cognitive development criticize and build upon Jean Piaget's theory of cognitive development. Overview The neo-Piagetian theories aim to correct one or more of the following weaknesses in Piaget's theory: * Piaget's developmental stage theory proposes that people develop through various stages of cognitive development, but his theory does not sufficiently explain why development from stage to stage occurs. Mansoor Niaz has argued that Piaget's stages were merely a heuristic for operationalizing his theory of equilibration. * Piaget's theory does not sufficiently explain individual differences in cognitive development. The theory does not account for the fact that some individuals move from stage to stage faster than other individuals. * The idea of rigid universal stages of cognitive development is incorrect. Research shows that the functioning of a person at a given age varies significantly from domain to domain (such as the understanding of social, ma ...

Self-consciousness
Self-consciousness is a heightened sense of awareness of oneself. It is not to be confused with consciousness in the sense of qualia. Historically, "self-consciousness" was synonymous with " self-awareness", referring to a state of awareness that one exists and that one has consciousness. While "self-conscious" and "self-aware" are still sometimes used interchangeably, particularly in philosophy, "self-consciousness" has commonly come to refer to a preoccupation with oneself, especially with how others might perceive one's appearance or one's actions. An unpleasant feeling of self-consciousness may occur when one realizes that one is being watched or observed, the feeling that "everyone is looking" at oneself. Some people are habitually more self-conscious than others. Unpleasant feelings of self-consciousness sometimes become associated with shyness or paranoia. Notable opponents of self-consciousness include Thomas Carlyle. Impairment When feeling self-conscious, one become ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Objective Self-awareness
Objective self-awareness is attention focused on the self as a socially evaluable object, as defined by Shelley Duval, Robert Wicklund, and other contemporary social psychologists. Since the original debut of Duval and Wicklund's self-awareness theory in 1972, many experimental psychologists have refined theory and ideas concerning the causes and consequences of self-focused attention. Self-focused attention or self-awareness as often discussed in the context of social psychology refers to ''situational'' self-awareness, as opposed to ''dispositional'' self-focus. Dispositional self-focus more accurately relates to the construct of self-consciousness, which allows psychologists to measure individual differences in the ''tendency'' to think about and attend to the self. History and description Prior to the development of the specific idea of objective self-awareness by Duval and Wicklund in the 1970s, psychologists, philosophers, and sociologists pursued scholarly work relate ...

Satiety
Satiety ( /səˈtaɪ.ə.ti/ ''sə-TYE-ə-tee'') is a state or condition of fullness gratified beyond the point of satisfaction, the opposite of hunger. Following satiation (meal termination), satiety is a feeling of fullness lasting until the next meal. When food is present in the GI tract after a meal, satiety signals overrule hunger signals, but satiety slowly fades as hunger increases. The satiety center in animals is located in ventromedial nucleus of the hypothalamus. Mechanism Satiety is signaled through the vagus nerve as well as circulating hormones. During intake of a meal, the stomach must stretch to accommodate this increased volume. This gastric accommodation activates stretch receptors in the proximal (upper) portion of the stomach. These receptors then signal through afferent vagus nerve fibers to the hypothalamus, increasing satiety. Signalling factors In addition, as the food moves into the duodenum, duodenal cells release multiple substances that affect di ...

Anorexia Nervosa
Anorexia nervosa (AN), often referred to simply as anorexia, is an eating disorder characterized by Calorie restriction, food restriction, body image disturbance, fear of gaining weight, and an overpowering desire to be thin. Individuals with anorexia nervosa have a fear of being overweight or being seen as such, despite the fact that they are typically underweight. The DSM-5 describes this perceptual symptom as "disturbance in the way in which one's body weight or shape is experienced". In research and clinical settings, this symptom is called "body image disturbance" or Body dysmorphic disorder, body dysmorphia. Individuals with anorexia nervosa also often deny that they have a problem with low weight due to their altered perception of appearance. They may weigh themselves frequently, eat small amounts, and only eat certain foods. Some patients with anorexia nervosa Binge eating, binge eat and Purging disorder, purge to influence their weight or shape. Purging can manifest a ...

Obesity is a medical condition, considered by multiple organizations to be a disease, in which excess Adipose tissue, body fat has accumulated to such an extent that it can potentially have negative effects on health. People are classified as obese when their body mass index (BMI)—a person's weight divided by the square of the person's height—is over ; the range is defined as overweight. Some East Asian countries use lower values to calculate obesity. Obesity is a major cause of disability and is Obesity-associated morbidity, correlated with various diseases and conditions, particularly cardiovascular diseases, type 2 diabetes, obstructive sleep apnea, certain types of cancer, and osteoarthritis. Obesity has individual, socioeconomic, and environmental causes.
