The bi-directional hypothesis of language and action proposes that the sensorimotor and language comprehension areas of the brain exert reciprocal influence over one another. [ 1] This hypothesis argues that areas of the brain involved in movement and sensation, as well as movement itself, influence cognitive processes such as language ...
A significant example of directional selection in populations is the fluctuations of light and dark phenotypes in peppered moths in the 1800s. [16] During the industrial revolution, environmental conditions were rapidly changing with the newfound emission of dark, black smoke from factories that would change the color of trees, rocks, and other ...
Signalling theory. By stotting (also called pronking), a springbok (Antidorcas marsupialis) signals honestly to predators that it is young, fit, and not worth chasing. Within evolutionary biology, signalling theory is a body of theoretical work examining communication between individuals, both within species and across species.
Linguistic representations can be broken down into small discrete units which combine with each other in rule-governed ways. They are perceived categorically, not continuously. For example, English marks number with the plural morpheme /s/, which can be added to the end of nearly any noun. The plural morpheme is perceived categorically, not ...
Embodied language processing. Embodied cognition occurs when an organism's sensorimotor capacities (ability of the body to respond to its senses with movement), body and environment play an important role in thinking. The way in which a person's body and their surroundings interacts also allows for specific brain functions to develop and in the ...
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations. Charles Darwin popularised the term "natural selection", contrasting it with artificial selection, which is ...
Language and thought. The study of how language influences thought, and vice-versa, has a long history in a variety of fields. There are two bodies of thought forming around this debate. One body of thought stems from linguistics and is known as the Sapir–Whorf hypothesis. There is a strong and a weak version of the hypothesis which argue for ...
Double-barreled question. A double-barreled question (sometimes, double-direct question[1]) is an informal fallacy. It is committed when someone asks a question that touches upon more than one issue, yet allows only for one answer. [2][3][4] This may result in inaccuracies in the attitudes being measured for the question, as the respondent can ...
