Theory of the child’s mind (ToM)

A set of interrelated principles and propositions that explains something of why children think and feel as they do, how they come to understand other people’s minds or mental (beliefs, desires, emotions, imagination, intentions) states, and why and how changes come about.  The theory seemingly started with the question “Do the chimpanzee have a theory …

Theory of population pressure

A theory developed by Thomas R. Malthus (1766-1834) and published as An Essay on the Principle of Population in 1798. It can be summarised as follows 1. a plentiful food supply and supporting agricultural resources are necessary for the continuing existence of human populations, however 2. human populations increase at geometrical rates (i.e. 1, 2, …

Theory of neuronal group selection (TNGS)

Derived from Darwin’s theory of natural selection and also referred to as ‘Neural Darwinism’, it is process-oriented approach to brain functioning.  In a nutshell, TNGS posits non-instructive sensorimotor systems that can adapt to their environment.  Based on a multi-agent architecture rather than a connectionist network, the resulting autonomous agent imposes perceptual categorisation on the environment, …

Theory of natural selection

A theory devised independently by Darwin and Wallace and which through its integration with population genetics became the backbone of the Modern synthesis.  In general, it a process by which gene frequencies in a population change as a consequence of certain individuals being able to produce more descendants than others because they are better able to …

Theory of multiple intelligences

A view put forward by Howard Gardner that there  are eight multiple intelligences Linguistic, logical-mathematical, spatial, musical, bodily-kinesthetic, naturalist, interpersonal, and intrapersonal . See Embedded Figures Test (EFT), Intelligence, Mental modules, Triarchic theory of intelligence

Theory of molecular evolution

Also known as the neutral theory of protein evolution or the neutral mutation-genetic drift theory. According to Motoo Kimura, one of the originators of the theory in the late 1960s, most of evolution at the molecular level is adaptively neutral, based on the finding of widespread protein polymorphisms in natural populations. Much of this polymorphism …

Theory of descent with modification

Essentially, Darwin’s theory of speciation via descent from a common ancestor, and without the connotation that it is a progressive process as, for example, birds with flight can evolve into a flightless species. For him, and for the Modern synthesis, speciation is gradual, rather than saltatory, process arising from the accumulation of point mutations. The …

Theory

A conceptual framework within which observations are explained and new ones predicted. In its construction, a theory draws upon any existing principles and laws in a particular area of science, and then serves to generate hypotheses to test the explanations and predictions it offers, possibly with the aid of models.  A hypothesis that survives rigorous …
