Flynn Effect
The Flynn effect is the substantial and long-sustained increase in both fluid and crystallized intelligence test scores that were measured in many parts of the world over the 20th century. When intelligence quotient (IQ) tests are initially standardized using a sample of test-takers, by convention the average of the test results is set to 100 and their standard deviation is set to 15 or 16 IQ points. When IQ tests are revised, they are again standardized using a new sample of test-takers, usually born more recently than the first; the average result is set to 100. When the new test subjects take the older tests, in almost every case their average scores are significantly above 100. Test score increases have been continuous and approximately linear from the earliest years of testing to the present. For example, a study published in the year 2009 found that British children's average scores on the Raven's Progressive Matrices test rose by 14 IQ points from 1942 to 2008. Similar gain ...

Fluid And Crystallized Intelligence
The concepts of fluid intelligence (''g''f) and crystallized intelligence (''g''c) were introduced in 1963 by the psychologist Raymond Cattell. According to Cattell's psychometrically-based theory, general intelligence (''g'') is subdivided into ''g''f and ''g''c. Fluid intelligence is the ability to solve novel reasoning problems and is correlated with a number of important skills such as comprehension, problem-solving, and learning. Crystallized intelligence, on the other hand, involves the ability to deduce secondary relational abstractions by applying previously learned primary relational abstractions. History Fluid and crystallized intelligence are constructs originally conceptualized by Raymond Cattell. The concepts of fluid and crystallized intelligence were further developed by Cattell and his former student John L. Horn. Fluid versus crystallized intelligence Fluid intelligence (''g''f) refers to basic processes of reasoning and other mental activities that depend ...

Massive Resistance
Massive resistance was a strategy declared by U.S. Senator Harry F. Byrd Sr. of Virginia and his brother-in-law James M. Thomson, who represented Alexandria in the Virginia General Assembly, to get the state's white politicians to pass laws and policies to prevent public school desegregation, particularly after '' Brown v. Board of Education''. Many schools, and even an entire school system, were shut down in 1958 and 1959 in attempts to block integration, before both the Virginia Supreme Court and a special three-judge panel of Federal District judges from the Eastern District of Virginia, sitting at Norfolk, declared those policies unconstitutional. Although most of the laws created to implement massive resistance were overturned by state and federal courts within a year, some aspects of the campaign against integrated public schools continued in Virginia for many more years.

Virginia
Virginia, officially the Commonwealth of Virginia, is a state in the Mid-Atlantic and Southeastern regions of the United States, between the Atlantic Coast and the Appalachian Mountains. The geography and climate of the Commonwealth are shaped by the Blue Ridge Mountains and the Chesapeake Bay, which provide habitat for much of its flora and fauna. The capital of the Commonwealth is Richmond; Virginia Beach is the most-populous city, and Fairfax County is the most-populous political subdivision. The Commonwealth's population was over 8.65million, with 36% of them living in the Baltimore–Washington metropolitan area. The area's history begins with several indigenous groups, including the Powhatan. In 1607, the London Company established the Colony of Virginia as the first permanent English colony in the New World. Virginia's state nickname, the Old Dominion, is a reference to this status. Slave labor and land acquired from displaced native tribes fueled the gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arithmetic
Arithmetic () is an elementary part of mathematics that consists of the study of the properties of the traditional operations on numbers— addition, subtraction, multiplication, division, exponentiation, and extraction of roots. In the 19th century, Italian mathematician Giuseppe Peano formalized arithmetic with his Peano axioms, which are highly important to the field of mathematical logic today. History The prehistory of arithmetic is limited to a small number of artifacts, which may indicate the conception of addition and subtraction, the best-known being the Ishango bone from central Africa, dating from somewhere between 20,000 and 18,000 BC, although its interpretation is disputed. The earliest written records indicate the Egyptians and Babylonians used all the elementary arithmetic operations: addition, subtraction, multiplication, and division, as early as 2000 BC. These artifacts do not always reveal the specific process used for solving problems, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vocabulary
A vocabulary is a set of familiar words within a person's language. A vocabulary, usually developed with age, serves as a useful and fundamental tool for communication and acquiring knowledge. Acquiring an extensive vocabulary is one of the largest challenges in learning a second language. Definition and usage Vocabulary is commonly defined as "all the words known and used by a particular person". Productive and receptive knowledge The first major change distinction that must be made when evaluating word knowledge is whether the knowledge is productive (also called achieve or active) or receptive (also called receive or passive); even within those opposing categories, there is often no clear distinction. Words that are generally understood when heard or read or seen constitute a person's receptive vocabulary. These words may range from well known to barely known (see degree of knowledge below). A person's receptive vocabulary is usually the larger of the two. For exam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthur Jensen
Arthur Robert Jensen (August 24, 1923 – October 22, 2012) was an American psychologist and writer. He was a professor of educational psychology at the University of California, Berkeley. Jensen was known for his work in psychometrics and differential psychology, the study of how and why individuals differ behaviorally from one another. He was a major proponent of the hereditarian position in the nature and nurture debate, the position that genetics play a significant role in behavioral traits, such as intelligence and personality. He was the author of over 400 scientific papers published in refereed journals and sat on the editorial boards of the scientific journals ''Intelligence'' and '' Personality and Individual Differences''. Jensen was controversial, largely for his conclusions regarding the causes of race-based differences in IQ. A 2019 study found him to be the most controversial intelligence researcher among 55 persons covered. Early life Jensen was born Aug ...

Stanford–Binet Intelligence Scales
The Stanford–Binet Intelligence Scales (or more commonly the Stanford–Binet) is an individually-administered intelligence test that was revised from the original Binet–Simon Scale by Alfred Binet and Theodore Simon. The Stanford–Binet Intelligence Scale is now in its fifth edition (SB5), which was released in 2003. It is a cognitive ability and intelligence test that is used to diagnose developmental or intellectual deficiencies in young children. The test measures five weighted factors and consists of both verbal and nonverbal subtests. The five factors being tested are knowledge, quantitative reasoning, visual-spatial processing, working memory, and fluid reasoning. The development of the Stanford–Binet initiated the modern field of intelligence testing and was one of the first examples of an adaptive test. The test originated in France, then was revised in the United States. It was initially created by the French psychologist Alfred Binet, who, following the introdu ...

Ulric Neisser
Ulric Richard Gustav Neisser (December 8, 1928 – February 17, 2012) was a German-American psychologist, Cornell University professor, and member of the US National Academy of Sciences. He has been referred to as the "father of cognitive psychology". Neisser researched and wrote about perception and memory. He posited that a person's mental processes could be measured and subsequently analyzed.Martin, D. (2012, February 25). Ulric Neisser Is Dead at 83; Reshaped Study of the Mind. The New York Times. Pp. A20. In 1967, Neisser published ''Cognitive Psychology'', which he later said was considered an attack on behaviorist psychological paradigms. ''Cognitive Psychology'' brought Neisser instant fame and recognition in the field of psychology. While ''Cognitive Psychology'' was considered unconventional, it was Neisser's ''Cognition and Reality'' that contained some of his most controversial ideas. A main theme in ''Cognition and Reality'' is Neisser's advocacy for experiments ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semantic Memory
Semantic memory refers to general world knowledge that humans have accumulated throughout their lives. This general knowledge (word meanings, concepts, facts, and ideas) is intertwined in experience and dependent on culture. We can learn about new concepts by applying our knowledge learned from things in the past. Semantic memory is distinct from episodic memory, which is our memory of experiences and specific events that occur during our lives, from which we can recreate at any given point. For instance, semantic memory might contain information about what a cat is, whereas episodic memory might contain a specific memory of petting a particular cat. Semantic memory and episodic memory are both types of explicit memory (or declarative memory), that is, memory of facts or events that can be consciously recalled and "declared". The counterpart to declarative or explicit memory is nondeclarative memory or implicit memory. History The idea of semantic memory was first ...

NATO
The North Atlantic Treaty Organization (NATO, ; french: Organisation du traité de l'Atlantique nord, ), also called the North Atlantic Alliance, is an intergovernmental military alliance between 30 member states – 28 European and two North American. Established in the aftermath of World War II, the organization implemented the North Atlantic Treaty, signed in Washington, D.C., on 4 April 1949. NATO is a collective security system: its independent member states agree to defend each other against attacks by third parties. During the Cold War, NATO operated as a check on the perceived threat posed by the Soviet Union. The alliance remained in place after the dissolution of the Soviet Union and has been involved in military operations in the Balkans, the Middle East, South Asia, and Africa. The organization's motto is ''animus in consulendo liber'' (Latin for "a mind unfettered in deliberation"). NATO's main headquarters are located in Brussels, Belgium, while ...
