Scottish People
The Scots ( sco, Scots Fowk; gd, Albannaich) are an ethnic group and nation native to Scotland. Historically, they emerged in the early Middle Ages from an amalgamation of two Celtic-speaking peoples, the Picts and Gaels, who founded the Kingdom of Scotland (or ''Alba'') in the 9th century. In the following two centuries, the Celtic-speaking Cumbrians of Strathclyde and the Germanic-speaking Angles of north Northumbria became part of Scotland. In the High Middle Ages, during the 12th-century Davidian Revolution, small numbers of Norman nobles migrated to the Lowlands. In the 13th century, the Norse-Gaels of the Western Isles became part of Scotland, followed by the Norse of the Northern Isles in the 15th century. In modern usage, "Scottish people" or "Scots" refers to anyone whose linguistic, cultural, family ancestral or genetic origins are from Scotland. The Latin word ''Scoti'' originally referred to the Gaels, but came to describe all inhabitants of Scotland. Cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centre For Cognitive Ageing And Cognitive Epidemiology
The University of Edinburgh School of Philosophy, Psychology and Language Sciences (PPLS) is a school within the College of Humanities and Social Science at the University of Edinburgh. The School was formed in 2002 as a result of administrative restructuring, when several departments of what was then the Faculty of Arts were brought together. The University of Edinburgh's academic foundation is based on three Colleges containing a total of 22 Schools; among these is the School of Philosophy, Psychology, and Language Sciences (PPLS). The School is composed of three subject areas: * Philosophy * Psychology * Linguistics and English Language (LEL) Research Within the School, research in Psychology is organized along 3 broad themes: * Differential Psychology, which looks at individual differences in the way people think, behave, and feel emotions differently. * Human Cognitive Neuroscience, which studies memory, attention, executive function, visual memory, sensory integration, a ...

Genetic Correlation
In multivariate quantitative genetics, a genetic correlation (denoted r_g or r_a) is the proportion of variance that two traits share due to genetic causes, the correlation between the genetic influences on a trait and the genetic influences on a different trait Plomin et al., p. 123 estimating the degree of pleiotropy or causal overlap. A genetic correlation of 0 implies that the genetic effects on one trait are independent of the other, while a correlation of 1 implies that all of the genetic influences on the two traits are identical. The bivariate genetic correlation can be generalized to inferring genetic latent variable factors across > 2 traits using factor analysis. Genetic correlation models were introduced into behavioral genetics in the 1970s–1980s. Genetic correlations have applications in validation of genome-wide association study (GWAS) results, breeding, prediction of traits, and discovering the etiology of traits & diseases. They can be estimated using indivi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pearson Product-moment Correlation Coefficient
In statistics, the Pearson correlation coefficient (PCC, pronounced ) ― also known as Pearson's ''r'', the Pearson product-moment correlation coefficient (PPMCC), the bivariate correlation, or colloquially simply as the correlation coefficient ― is a measure of linear correlation between two sets of data. It is the ratio between the covariance of two variables and the product of their standard deviations; thus, it is essentially a normalized measurement of the covariance, such that the result always has a value between −1 and 1. As with covariance itself, the measure can only reflect a linear correlation of variables, and ignores many other types of relationships or correlations. As a simple example, one would expect the age and height of a sample of teenagers from a high school to have a Pearson correlation coefficient significantly greater than 0, but less than 1 (as 1 would represent an unrealistically perfect correlation). Naming and history It was developed by Karl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reliability (psychometrics)
In statistics and psychometrics, reliability is the overall consistency of a measure. A measure is said to have a high reliability if it produces similar results under consistent conditions:"It is the characteristic of a set of test scores that relates to the amount of random error from the measurement process that might be embedded in the scores. Scores that are highly reliable are precise, reproducible, and consistent from one testing occasion to another. That is, if the testing process were repeated with a group of test takers, essentially the same results would be obtained. Various kinds of reliability coefficients, with values ranging between 0.00 (much error) and 1.00 (no error), are usually used to indicate the amount of error in the scores." For example, measurements of people's height and weight are often extremely reliable.The Marketing Accountability Standards Board (MASB) endorses this definition as part of its ongoinCommon Language: Marketing Activities and Metrics Pr ...

Lothians
Lothian (; sco, Lowden, Loudan, -en, -o(u)n; gd, Lodainn ) is a region of the Scottish Lowlands, lying between the southern shore of the Firth of Forth and the Lammermuir Hills and the Moorfoot Hills. The principal settlement is the Scottish capital, Edinburgh, while other significant towns include Livingston, Linlithgow, Bathgate, Queensferry, Dalkeith, Bonnyrigg, Penicuik, Musselburgh, Prestonpans, North Berwick, Dunbar, Whitburn and Haddington. Historically, the term Lothian referred to a province encompassing most of what is now southeastern Scotland. In the 7th century it came under the control of the Anglian kingdom of Bernicia, the northern part of the later kingdom of Northumbria, but the Angles' grip on Lothian was quickly weakened following the Battle of Nechtansmere in which they were defeated by the Picts. Lothian was annexed to the Kingdom of Scotland around the 10th century. Subsequent Scottish history saw the region subdivided into three counties ...

Lothian Birth-cohort Studies
The Lothian birth-cohort studies are two ongoing cohort studies which primarily involve research into how childhood intelligence relates to intelligence and health in old age. The Lothian Birth Cohort studies of 1921 and 1936 have, respectively, followed up Lothian-based participants in the Scottish Mental Surveys of 1932 and 1947 in old age. Scottish Mental Survey data has provided a measure of the intelligence of Lothian Birth Cohort participants at age 11, which has enabled the investigation of how childhood intelligence relates to cognition, mental health and physical health in old age. Major cognitive ageing findings of the studies have concerned the stability of intelligence from childhood to old age, the influence of genetics on cognitive function and decline, and the role of the brain's white matter integrity in successful cognitive ageing. The studies have also been at the vanguard of the field of cognitive epidemiology, which explores how intelligence relates to physical ...

History In 1947, the board of directors of the publishing company Annual Reviews asked a number of psychologists if it would be useful to have a journal that published an annual volume of review articles that summarized recent developments in the field. Responses were very positive, so in September 1947 they announced that the first volume of the ''Annual Review of Psychology'' would be published in 1950. Previous attempts to establish such a journal in the early 1940s were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neuroscience And Intelligence
Neuroscience and intelligence refers to the various neurological factors that are partly responsible for the variation of intelligence within species or between different species. A large amount of research in this area has been focused on the neural basis of human intelligence. Historic approaches to study the neuroscience of intelligence consisted of correlating external head parameters, for example head circumference, to intelligence. Post-mortem measures of brain weight and brain volume have also been used. More recent methodologies focus on examining correlates of intelligence within the living brain using techniques such as magnetic resonance imaging ( MRI), functional MRI (fMRI), electroencephalography (EEG), positron emission tomography and other non-invasive measures of brain structure and activity. Researchers have been able to identify correlates of intelligence within the brain and its functioning. These include overall brain volume, grey matter volume, white matter volu ...
