Evolutionary Psychology Of Language
Evolutionary psychology of language is the study of the evolutionary history of language as a psychological faculty within the discipline of evolutionary psychology. It makes the assumption that language is the result of a Darwinian adaptation. There are many competing theories of how language might have evolved, if indeed it is an evolutionary adaptation. They stem from the belief that language development could result from an adaptation, an exaptation, or a by-product. Genetics also influence the study of the evolution of language. It has been speculated that the FOXP2 gene may be what gives humans the ability to develop grammar and syntax. Language evolution theories In the debate surrounding the evolutionary psychology of language, three sides emerge: those who believe in language as an adaptation, those who believe it is a by-product of another adaptation, and those who believe it is an exaptation. Adaptation Scientist and psychologists Steven Pinker and Paul Bloom argue t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Evolutionary Psychology
Evolutionary psychology is a theoretical approach in psychology that examines cognition and behavior from a modern evolutionary perspective. It seeks to identify human psychological adaptations with regards to the ancestral problems they evolved to solve. In this framework, psychological traits and mechanisms are either functional products of natural and sexual selection, non-adaptive by-products of other adaptive traits, or noise. Adaptationist thinking about physiological mechanisms, such as the heart, lungs, and the liver, is common in evolutionary biology. Evolutionary psychologists apply the same thinking in psychology, arguing that just as the heart evolved to pump blood, and the liver evolved to detoxify poisons, there is modularity of mind in that different psychological mechanisms evolved to solve different adaptive problems. These evolutionary psychologists argue that much of human behavior is the output of psychological adaptations that evolved to solve recurrent p ...

Organic (model)
Organic describes forms, methods and patterns found in living systems such as the organisation of cells, to populations, communities, and ecosystems. Typically organic models stress the interdependence of the component parts, as well as their differentiation. Other properties of organic models include: *the growth, life or development cycle *the ability to adapt, learn, and evolve *emergent behaviour or emergent properties *steady change or growth, as opposed to instant change *regulatory feedback *composed of heterogeneous (diverse) parts Organic models are used especially in the design of artificial systems, and the description of social systems and constructs. Uses In the social sciences, the organic model has been drawn upon for ideas such as mechanical and organic solidarity and organic unity. Carl Ritter advanced the idea of Lebensraum using the metaphor of an organic, growing state. In computer science, organic networks grow in an ad hoc manner, while organic computing ...

United Kingdom
The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a country in Europe, off the north-western coast of the continental mainland. It comprises England, Scotland, Wales and Northern Ireland. The United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland, and many smaller islands within the British Isles. Northern Ireland shares a land border with the Republic of Ireland; otherwise, the United Kingdom is surrounded by the Atlantic Ocean, the North Sea, the English Channel, the Celtic Sea and the Irish Sea. The total area of the United Kingdom is , with an estimated 2020 population of more than 67 million people. The United Kingdom has evolved from a series of annexations, unions and separations of constituent countries over several hundred years. The Treaty of Union between the Kingdom of England (which included Wales, annexed in 1542) and the Kingdom of Scotland in 170 ...

KE Family
The KE family is a medical name designated for a British family, about half of whom exhibit a severe speech disorder called developmental verbal dyspraxia. It is the first family with speech disorder to be investigated using genetic analyses, by which the speech impairment is discovered to be due to genetic mutation, and from which the gene ''FOXP2'', often dubbed the "language gene", was discovered. Their condition is also the first human speech and language disorder known to exhibit strict Mendelian inheritance. Brought to medical attention from their school children in the late 1980s, the case of KE family was taken up at the UCL Institute of Child Health in London in 1990. Initial report suggested that the family was affected by a genetic disorder. Canadian linguist Myrna Gopnik suggested that the disorder was characterized primarily by grammatical deficiency, supporting the controversial notion of a "grammar gene". Geneticists at the University of Oxford determined that the co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myrna Gopnik
Myrna Lee Gopnik (born 1935) is a Canadian linguist. She is a Professor Emerita of Linguistics at McGill University. She is known for her research on the KE family, an English family with several members affected by specific language impairment. Gopnik is generally credited with an important early evaluation of the KE family, and with making this family known to the wider scientific community. Subsequent research by Anthony Monaco, Simon Fisher and colleagues at Oxford University identified a mutation in the FOXP2 gene as a cause of the KE family's disorder (see: A forkhead-domain gene is mutated in a severe speech and language disorder.Lai CS, Fisher SE, Hurst JA, Vargha-Khadem F, Monaco AP. ''Nature''. 2001 vol. 413(6855):pp. 519–23.) Gopnik's son Adam is a well-known novelist and writer for the New Yorker, her son Blake has a doctorate from University of Oxford and is an art critic, and her daughter Alison is a developmental psychology professor at UC-Berkeley Th ...

Gene
In biology, the word gene (from , ; "...Wilhelm Johannsen coined the word gene to describe the Mendelian units of heredity..." meaning ''generation'' or ''birth'' or ''gender'') can have several different meanings. The Mendelian gene is a basic unit of heredity and the molecular gene is a sequence of nucleotides in DNA that is transcribed to produce a functional RNA. There are two types of molecular genes: protein-coding genes and noncoding genes. During gene expression, the DNA is first copied into RNA. The RNA can be directly functional or be the intermediate template for a protein that performs a function. The transmission of genes to an organism's offspring is the basis of the inheritance of phenotypic traits. These genes make up different DNA sequences called genotypes. Genotypes along with environmental and developmental factors determine what the phenotypes will be. Most biological traits are under the influence of polygenes (many different genes) as well as gen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protein FOXP2 PDB 2a07
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residue (biochemistry), residues. Proteins perform a vast array of functions within organisms, including Enzyme catalysis, catalysing metabolic reactions, DNA replication, Cell signaling, responding to stimuli, providing Cytoskeleton, structure to cells and Fibrous protein, organisms, and Intracellular transport, transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the Nucleic acid sequence, nucleotide sequence of their genes, and which usually results in protein folding into a specific Protein structure, 3D structure that determines its activity. A linear chain of amino acid residues is called a polypeptide. A protein contains at least one long polypeptide. Short polypeptides, containing less than 20–30 residues, are rarely considered to be proteins and are commonly called pept ...

Baldwin Effect
In evolutionary biology, the Baldwin effect, a phenotype-first theory of evolution, describes the effect of learned behaviour on evolution. James Mark Baldwin and others suggested during the eclipse of Darwinism in the late 19th century that an organism's ''ability to learn'' new behaviours (e.g. to acclimatise to a new stressor) will affect its reproductive success and will therefore have an effect on the genetic makeup of its species through natural selection. Though this process appears similar to Lamarckism, that view proposes that living things ''inherited'' their parents' acquired characteristics. The Baldwin effect has been independently proposed several times, and today it is generally recognized as part of the modern synthesis. "A New Factor in Evolution" The effect, then unnamed, was put forward in 1896 in a paper "A New Factor in Evolution" by the American psychologist James Mark Baldwin, with a second paper in 1897. The paper proposed a mechanism for specific selecti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Larynx
The larynx (), commonly called the voice box, is an organ in the top of the neck involved in breathing, producing sound and protecting the trachea against food aspiration. The opening of larynx into pharynx known as the laryngeal inlet is about 4–5 centimeters in diameter. The larynx houses the vocal cords, and manipulates pitch and volume, which is essential for phonation. It is situated just below where the tract of the pharynx splits into the trachea and the esophagus. The word ʻlarynxʼ (plural ʻlaryngesʼ) comes from the Ancient Greek word ''lárunx'' ʻlarynx, gullet, throat.ʼ Structure The triangle-shaped larynx consists largely of cartilages that are attached to one another, and to surrounding structures, by muscles or by fibrous and elastic tissue components. The larynx is lined by a ciliated columnar epithelium except for the vocal folds. The cavity of the larynx extends from its triangle-shaped inlet, to the epiglottis, and to the circular outlet at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cognitive Process
Cognition refers to "the mental action or process of acquiring knowledge and understanding through thought, experience, and the senses". It encompasses all aspects of intellectual functions and processes such as: perception, attention, thought, intelligence, the formation of knowledge, memory and working memory, judgment and evaluation, reasoning and computation, problem solving and decision making, comprehension and production of language. Imagination is also a cognitive process, it is considered as such because it involves thinking about possibilities. Cognitive processes use existing knowledge and discover new knowledge. Cognitive processes are analyzed from different perspectives within different contexts, notably in the fields of linguistics, musicology, anesthesia, neuroscience, psychiatry, psychology, education, philosophy, anthropology, biology, systemics, logic, and computer science. These and other approaches to the analysis of cognition (such as embodied cognition) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Symbolic Communication
Symbolic communication is the exchange of messages that change ''a priori'' expectation of events. Examples of this are modern communication technology and the exchange of information amongst animals. By referring to objects and ideas not present at the time of communication, a world of possibility is opened. In humans, this process has been compounded to result in the current state of modernity. A symbol is anything one says or does to describe something, and that something can have an array of many meanings. Once the symbols are learned by a particular group, that symbol stays intact with the object. Symbolic communication includes gestures, body language and facial expressions, as well as vocal moans that can indicate what an individual wants without having to speak. Research argues that about 55% of all communication stems from nonverbal language. Symbolic communication ranges from sign language to braille to tactile communication skills.
