Kurt W. Fischer (June 9, 1943 – March 30, 2020) was an educator, author, and researcher in the field of neuroscience and education. Until his retirement in 2015, he was the Charles Bigelow Professor of Education and Director of the Mind, Brain, and Education Program at Harvard Graduate School of Education .
Fisher's principle is an evolutionary model that explains why the sex ratio of most species that produce offspring through sexual reproduction is approximately 1:1 between males and females. A. W. F. Edwards has remarked that it is "probably the most celebrated argument in evolutionary biology". [1]
Fisher likened it to the law of entropy in physics, stating that "It is not a little instructive that so similar a law should hold the supreme position among the biological sciences". The model of quasi-linkage equilibrium was introduced by Motoo Kimura in 1965 as an approximation in the case of weak selection and weak epistasis .
Kurt W. Fischer advanced a theory that integrates Piaget's notion of stages in cognitive development with notions from learning theory and skill construction as explained by the cognitive psychology of the 1960s. [19] Fischer's conception of the stages of cognitive development is very similar to that of Case. That is, he describes four major ...
Educational neuroscience (or neuroeducation, [1] a component of Mind Brain and Education) is an emerging scientific field that brings together researchers in cognitive neuroscience, developmental cognitive neuroscience, educational psychology, educational technology, education theory and other related disciplines to explore the interactions between biological processes and education.
Two useful introductions to the fundamental theory underlying the unit of selection issue and debate, which also present examples of multi-level selection from the entire range of the biological hierarchy (typically with entities at level N-1 competing for increased representation, i.e., higher frequency, at the immediately higher level N, e.g., organisms in populations or cell lineages in ...
Cognitive biology is an emerging science that regards natural cognition as a biological function. [1] It is based on the theoretical assumption that every organism—whether a single cell or multicellular—is continually engaged in systematic acts of cognition coupled with intentional behaviors, i.e., a sensory-motor coupling. [2]
The Genetical Theory of Natural Selection is a book by Ronald Fisher which combines Mendelian genetics with Charles Darwin's theory of natural selection, [1] with Fisher being the first to argue that "Mendelism therefore validates Darwinism" [2] and stating with regard to mutations that "The vast majority of large mutations are deleterious; small mutations are both far more frequent and more ...
