Cognitive Advantages Of Bilingualism
Bilingualism, a subset of multilingualism, means having proficiency in two or more languages. A bilingual individual is traditionally defined as someone who understands and produces two or more languages on a regular basis. A bilingual individual's initial exposure to both languages may start in early childhood, e.g. before age 3, but exposure may also begin later in life, in monolingual or bilingual education. Equal proficiency in a bilingual individuals' languages is rarely seen as it typically varies by domain. For example, a bilingual individual may have greater proficiency for work-related terms in one language, and family-related terms in another language. Being bilingual has been linked to a number of cognitive benefits. Research on how a bilingual individual's first language (L1) and second language (L2) interact shows that both languages have an influence on the function of one-another and on cognitive function outside of language. Research on executive functions like wor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multilingualism
Multilingualism is the use of more than one language, either by an individual speaker or by a group of speakers. It is believed that multilingual speakers outnumber monolingual speakers in the world's population. More than half of all Europeans claim to speak at least one language other than their mother tongue; but many read and write in one language. Multilingualism is advantageous for people wanting to participate in trade, globalization and cultural openness. Owing to the ease of access to information facilitated by the Internet, individuals' exposure to multiple languages has become increasingly possible. People who speak several languages are also called polyglots. Multilingual speakers have acquired and maintained at least one language during childhood, the so-called first language (L1). The first language (sometimes also referred to as the mother tongue) is usually acquired without formal education, by mechanisms about which scholars disagree. Children acquiri ...

American Institutes For Research
The American Institutes for Research (AIR) is a nonprofit, nonpartisan behavioral and social science research, evaluation and technical assistance organization based in Arlington, Virginia. One of the world's largest social science research organizations, AIR has more than 1,800 staff in locations across the United States and abroad. In 2010 and 2011, ''The Washington Post'' selected AIR as one of the top ten nonprofit firms in the Washington metropolitan area. History AIR's founder, John C. Flanagan, a pioneer in aviation psychology, is known for developing the critical incident technique, an innovative method for screening and selecting personnel. While working for the U.S. Army Air Forces during World War II, Flanagan developed CIT as an aptitude test to identify potential combat pilots. Later, the technique was adapted for other industries, and CIT is still a model for numerous organizations and researchers. Flanagan established American Institutes for Research in 1946. H ...

Phonetic
Phonetics is a branch of linguistics that studies how humans produce and perceive sounds, or in the case of sign languages, the equivalent aspects of sign. Linguists who specialize in studying the physical properties of speech are phoneticians. The field of phonetics is traditionally divided into three sub-disciplines based on the research questions involved such as how humans plan and execute movements to produce speech ( articulatory phonetics), how various movements affect the properties of the resulting sound ( acoustic phonetics), or how humans convert sound waves to linguistic information ( auditory phonetics). Traditionally, the minimal linguistic unit of phonetics is the phone—a speech sound in a language which differs from the phonological unit of phoneme; the phoneme is an abstract categorization of phones. Phonetics deals with two aspects of human speech: production—the ways humans make sounds—and perception—the way speech is understood. The communicative mo ...

Executive Function
In cognitive science and neuropsychology, executive functions (collectively referred to as executive function and cognitive control) are a set of cognitive processes that are necessary for the cognitive control of behavior: selecting and successfully monitoring behaviors that facilitate the attainment of chosen goals. Executive functions include basic cognitive processes such as attentional control, cognitive inhibition, inhibitory control, working memory, and cognitive flexibility. Higher-order executive functions require the simultaneous use of multiple basic executive functions and include planning and fluid intelligence (e.g., reasoning and problem-solving). Executive functions gradually develop and change across the lifespan of an individual and can be improved at any time over the course of a person's life. Similarly, these cognitive processes can be adversely affected by a variety of events which affect an individual. Both neuropsychological tests (e.g., the Stroop te ...

Gray Matter
Grey matter is a major component of the central nervous system, consisting of neuronal cell bodies, neuropil (dendrites and unmyelinated axons), glial cells (astrocytes and oligodendrocytes), synapses, and capillaries. Grey matter is distinguished from white matter in that it contains numerous cell bodies and relatively few myelinated axons, while white matter contains relatively few cell bodies and is composed chiefly of long-range myelinated axons. The colour difference arises mainly from the whiteness of myelin. In living tissue, grey matter actually has a very light grey colour with yellowish or pinkish hues, which come from capillary blood vessels and neuronal cell bodies. Structure Grey matter refers to unmyelinated neurons and other cells of the central nervous system. It is present in the brain, brainstem and cerebellum, and present throughout the spinal cord. Grey matter is distributed at the surface of the cerebral hemispheres (cerebral cortex) and of the cerebellu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cognitive Reserve
Cognitive reserve is the mind's and brain's resistance to damage of the brain. The mind's resilience is evaluated behaviorally, whereas the neuropathological damage is evaluated histologically, although damage may be estimated using blood-based markers and imaging methods. There are two models that can be used when exploring the concept of "reserve": ''brain reserve'' and ''cognitive reserve''. These terms, albeit often used interchangeably in the literature, provide a useful way of discussing the models. Using a computer analogy brain reserve can be seen as hardware and cognitive reserve as software. All these factors are currently believed to contribute to global reserve. Cognitive reserve is commonly used to refer to both brain and cognitive reserves in the literature. In 1988 a study published in ''Annals of Neurology'' reporting findings from post-mortem examinations on 137 elderly persons unexpectedly revealed that there was a discrepancy between the degree of Alzheimer's dis ...

Theory Of Mind
In psychology, theory of mind refers to the capacity to understand other people by ascribing mental states to them (that is, surmising what is happening in their mind). This includes the knowledge that others' mental states may be different from one's own states and include beliefs, desires, intentions, emotions, and thoughts. Possessing a functional theory of mind is considered crucial for success in everyday human social interactions. People use such a theory when analyzing, judging, and inferring others' behaviors. The discovery and development of theory of mind primarily came from studies done with animals and infants. Factors including 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 can occur in people with autism (although this is contentious), anorexia nervosa, schizophrenia, dysphoria, attention deficit hyperactiv ...

Metalinguistic
Metalinguistics is the branch of linguistics that studies language and its relationship to other cultural behaviors. It is the study of dialogue relationships between units of speech communication as manifestations and enactments of co-existence. Jacob L. Mey in his book, ''Trends in Linguistics'', describes Mikhail Bakhtin's interpretation of metalinguistics as "encompassing the life history of a speech community, with an orientation toward a study of large events in the speech life of people and embody changes in various cultures and ages." Literacy development Metalinguistic skills involve understanding of the rules used to govern language. Scholar Patrick Hartwell points out how substantial it is for students to develop these capabilities, especially heightened phonological awareness, which is a key precursor to literacy. An essential aspect to language development is focused on the student being aware of language and the components of language. This idea is also examined in ...

Stroop Task
---- ---- Naming the font color of a printed word is an easier and quicker task if word meaning and font color are congruent. If two words are both printed in red, the average time to say "red" in response to the written word "green" is greater than the time to say "red" in response to the written word "mouse". In psychology, the Stroop effect is the delay in reaction time between congruent and incongruent stimuli. The effect has been used to create a psychological test (the Stroop test) that is widely used in clinical practice and investigation. A basic task that demonstrates this effect occurs when there is a mismatch between the name of a color (e.g., "blue", "green", or "red") and the color it is printed on (i.e., the word "red" printed in blue ink instead of red ink). When asked to name the color of the word it takes longer and is more prone to errors when the color of the ink does not match the name of the color. The effect is named after John Ridley Stroop, wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electrophysiology
Electrophysiology (from Ancient Greek, Greek , ''ēlektron'', "amber" [see the Electron#Etymology, etymology of "electron"]; , ''physis'', "nature, origin"; and , ''-logy, -logia'') is the branch of physiology that studies the electrical properties of biological cell (biology), cells and tissues. It involves measurements of voltage changes or electric current or manipulations on a wide variety of scales from single ion channel proteins to whole organs like the heart. In neuroscience, it includes measurements of the electrical activity of neurons, and, in particular, action potential activity. Recordings of large-scale electric signals from the nervous system, such as electroencephalography, may also be referred to as electrophysiological recordings. They are useful for electrodiagnostic medicine, electrodiagnosis and monitoring (medicine), monitoring.
