Hypercalculia
Hypercalculia is "a specific Developmental psychology, developmental condition in which the ability to perform mathematics, mathematical calculations is significantly superior to general learning ability and to school attainment in maths." A 2002 neuroimaging study of a child with hypercalculia suggested greater brain volume in the right temporal lobe. Serial Single-photon emission computed tomography, SPECT scans revealed hyperperfusion over right Parietal lobe, parietal areas during performance of arithmetic tasks. Math and reading achievement profiles in autistic individuals Children at any age may be stronger in language or in mathematics, but very rarely in both. Autistic children are no different. A rare example of a child with multiple savant tendencies is a case study of a thirteen year old girl. Pacheva, Panoy, Gillberg, and Neville discovered this young woman has not only hypercalculia abilities, but also showcases hyperlexia, and hypermnesia capabilities. A study publi ...

Mental Calculator
Human calculator is a term to describe a person with a prodigious ability in some area of mental calculation (such as adding, subtracting, multiplying or dividing large numbers). The world's best mental calculators are invited every two years to compete for the Mental Calculation World Cup. On July 17, 2022, at Heinz Nixdorf MuseumsForum in Paderborn city of Germany, 12-year-old Indian mental calculator Aaryan Nitin Shukla clinched the title to become the new World Champion. Aaryan ended the dominance of Japanese mental calculators who won the competitions during 2018-Tomohiro Iseda and 2016-Yuki Kimura. Tomohiro Iseda (2018) was the third Japanese person to win the Cup, after Naofumi Ogasawara (2012) and Yuki Kimura (2016). Shakuntala Devi from India has been often mentioned on the Guinness World Records. Neelakantha Bhanu Prakash from India has been often mentioned on the Limca Book of Records for racing past the speed of a calculator in addition. Srilankan-Malaysian perfo ...

Dyscalculia
Dyscalculia () is a disability resulting in difficulty learning or comprehending arithmetic, such as difficulty in understanding numbers, learning how to manipulate numbers, performing mathematical calculations, and learning facts in mathematics. It is sometimes colloquially referred to "math dyslexia", though this analogy is misleading as they are distinct syndromes. Dyscalculia is associated with dysfunction in the region around the intraparietal sulcus and potentially also the frontal lobe. Dyscalculia does not reflect a general deficit in cognitive abilities or difficulties with time, measurement, and spatial reasoning. Estimates of the prevalence of dyscalculia range between 3 and 6% of the population. In 2015 it was established that 11% of children with dyscalculia also have ADHD. Dyscalculia has also been associated with Turner syndrome and people who have spina bifida. Mathematical disabilities can occur as the result of some types of brain injury, in which case the term ...

Acalculia
Acalculia is an acquired impairment in which people have difficulty performing simple mathematical tasks, such as adding, subtracting, multiplying and even simply stating which of two numbers is larger. Acalculia is distinguished from dyscalculia in that acalculia is acquired late in life due to neurological injury such as stroke, while dyscalculia is a specific developmental disorder first observed during the acquisition of mathematical knowledge. The name comes from the Greek "a" meaning "not" and Latin "calculare", which means "to count". Signs and symptoms Calculation impairments include the inability to perform simple mathematical operations, such as addition, subtraction, division, and multiplication. As calculation involves the integration of several cognitive skills, it is understood that an individual with acalculia (or calculation difficulties) is deficient in any of the following four realms: 1) understanding that every number represents a value and immediately regi ...

Developmental Psychology
Developmental psychology is the science, scientific study of how and why humans grow, change, and adapt across the course of their lives. Originally concerned with infants and children, the field has expanded to include adolescence, adult development, aging, and the entire lifespan. Developmental psychologists aim to explain how thinking, feeling, and behaviors change throughout life. This field examines change across three major dimensions, which are physical development, cognitive development, and social emotional development. Within these three dimensions are a broad range of topics including motor skills, executive functions, morality, moral understanding, language acquisition, social change, personality, emotional development, self-concept, and identity formation. Developmental psychology examines the influences of nature ''and'' nurture on the process of human development, as well as processes of change in context across time. Many researchers are interested in the inter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Savant Syndrome
Savant syndrome () is a rare condition in which someone with significant mental disabilities demonstrates certain abilities far in excess of average. The skills that savants excel at are generally related to memory. This may include rapid calculation, artistic ability, map making, or musical ability. Usually, only one exceptional skill is present. Those with the condition generally have a neurodevelopmental disorder such as autism spectrum disorder or have a brain injury. About half of cases are associated with autism, and these individuals may be known as "autistic savants". While the condition usually becomes apparent in childhood, some cases develop later in life. It is not recognized as a mental disorder within the DSM-5. Savant syndrome is estimated to affect around one in a million people. The condition affects more males than females, at a ratio of 6:1. The first medical account of the condition was in 1783. Among those with autism, 1 in 10 to 1 in 200 have savant synd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Numerical Cognition
Numerical cognition is a subdiscipline of cognitive science that studies the cognitive, developmental and neural bases of numbers and mathematics. As with many cognitive science endeavors, this is a highly interdisciplinary topic, and includes researchers in cognitive psychology, developmental psychology, neuroscience and cognitive linguistics. This discipline, although it may interact with questions in the philosophy of mathematics, is primarily concerned with empirical questions. Topics included in the domain of numerical cognition include: *How do non-human animals process numerosity? *How do infants acquire an understanding of numbers (and how much is inborn)? *How do humans associate linguistic symbols with numerical quantities? *How do these capacities underlie our ability to perform complex calculations? *What are the neural bases of these abilities, both in humans and in non-humans? *What metaphorical capacities and processes allow us to extend our numerical understandin ...

AI & Society
''AI & Society'' is a quarterly peer-reviewed scientific journal published by Springer. The editor-in-chief is Karamjit S. Gill, Brighton University. ''AI & Society'' has been running since 1987. It covers all aspects of artificial intelligence and its effects on and interaction with society. History The journal was originally conceived as a reaction to the attitude of Technological Determinism emerging from Silicon Valley and was designed to be the theoretical underpinning of the concept of Human-Centred Systems a concepted developed by Mike Cooley in his book ''Architect or Bee?''. The idea for the journal arose from the year-long secondment of Prof Karamjit Gill from 1985 to 1986 to work with Mike Cooley at the Greater London Enterprise Board (GLEB). During his secondment Karamjit organised a seminar “Knowledge and Society” at the MIT in Boston with Prof Joseph Weizenbaum and the resulting discussion led to Karamjit’s suggestion to develop a journal. Mike Cooley be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artificial Intelligence
Artificial intelligence (AI) is intelligence—perceiving, synthesizing, and inferring information—demonstrated by machines, as opposed to intelligence displayed by animals and humans. Example tasks in which this is done include speech recognition, computer vision, translation between (natural) languages, as well as other mappings of inputs. The ''Oxford English Dictionary'' of Oxford University Press defines artificial intelligence as: the theory and development of computer systems able to perform tasks that normally require human intelligence, such as visual perception, speech recognition, decision-making, and translation between languages. AI applications include advanced web search engines (e.g., Google), recommendation systems (used by YouTube, Amazon and Netflix), understanding human speech (such as Siri and Alexa), self-driving cars (e.g., Tesla), automated decision-making and competing at the highest level in strategic game systems (such as chess and Go). ...

Biological Sciences
Biology is the scientific study of life. It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. For instance, all organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations. Another major theme is evolution, which explains the unity and diversity of life. Energy processing is also important to life as it allows organisms to move, grow, and reproduce. Finally, all organisms are able to regulate their own internal environments. Biologists are able to study life at multiple levels of organization, from the molecular biology of a cell to the anatomy and physiology of plants and animals, and evolution of populations.Based on definition from: Hence, there are multiple subdisciplines within biology, each defined by the nature of their research questions and the tools that they use. Like other scientists, biologists use the scientific metho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
