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, named after researcher James Flynn (1934–2020). [ 1 ][ 2 ] When intelligence quotient (IQ) tests are initially standardized using a sample of test-takers ...
Flynn's taxonomy is a classification of computer architectures, proposed by Michael J. Flynn in 1966 [1] and extended in 1972. [2] The classification system has stuck, and it has been used as a tool in the design of modern processors and their functionalities. Since the rise of multiprocessing central processing units (CPUs), a multiprogramming ...
Flynn's taxonomy. Single instruction, multiple data (SIMD) is a type of parallel processing in Flynn's taxonomy. SIMD can be internal (part of the hardware design) and it can be directly accessible through an instruction set architecture (ISA), but it should not be confused with an ISA. SIMD describes computers with multiple processing elements ...
The Dickens/Flynn model, [1] as outlined in the book, attempts to explain the Flynn effect by suggesting that genes and environment have interacted in manner which leads to a multiplying of influence from both on IQ scores. In particular, people now live in a cognitive environment that has changed substantially over the past century.
MPMD. In computing, single instruction stream, single data stream (SISD) is a computer architecture in which a single uni-core processor executes a single instruction stream, to operate on data stored in a single memory. This corresponds to the von Neumann architecture. SISD is one of the four main classifications as defined in Flynn's taxonomy ...
Reviews by Flynn and Dickens, [39] Mackintosh, [75] and Nisbett et al. accept the gradual closing of the gap as a fact. [76] Flynn and Dickens summarize this trend, stating, "The constancy of the Black-White IQ gap is a myth and therefore cannot be cited as evidence that the racial IQ gap is genetic in origin." [39]
MPMD. In computing, multiple instruction, single data (MISD) is a type of parallel computing architecture where many functional units perform different operations on the same data. Pipeline architectures belong to this type, though a purist might say that the data is different after processing by each stage in the pipeline.
