What is an adaptive theory?

Adaptive theory is the name of theories across several scientific disciplines that are engaged in the ability of the system to adapt to what happened earlier. In some disciplines, the system is self -confident and the theory tries to explain why it makes a decision. Other adaptive theories try to explain how an adaptive system that is not aware of self -confidence still selects for certain conditions.

In biology, adaptive theory is synonymous with natural selection, the main part of the theory of evolution. The natural selection states that due to a number of features within the species, those features that help individuals survive and overgrown will become a predominance. A classic example is an example of a pepper for which the proportion of light and dark colored moths in the population modified to help the bridges remain masked when industrial pollution darkened its environment. Another common example is the patterns of sleep, which is assumed that Remain is adapted to the need to warn about possible predators. Classic dArwinist theory states that a natural selection is a primary means that one species develops into a different species, and most non-darwinists acknowledge that natural selection is controlled by features proven in the species. It examines how the neural network holds expectations and compares with real feelings and stimulations. Neurologists try to determine how the human brain works. Programmers try to find ways to duplicate human learning.

In medicine, adaptive theory of ROY suggests that the purpose of nursing is to help patients adapt to the situation of their injury or illness. This includes assistance in patient care physically and help the patient mentally and emotionally adapt to the long -term consequences of his condition. The theory is the work of Sister Callista Roy, Professor and Sisters of the theorist at Boston College of Nursing, and is partly based on the work of psychologist Harry Helson.

Helson's theory at the levelThe adaptation was that the individual judgment is a function of previous experience. This observation of common sense has several consequences. Each individual has a unique experience, so his decision can differ from what others would prove in the same situation. Individuals adapt to what their current situations are, so everyone tends to perceive their current current status as normal. Adaptive theory also plays a role in criminal profiling, in which police officers try to anticipate how criminals will behave on the basis of proven behavior.

Adaptive theory in economics is partly based on Helson's work in psychology. The classical economy deals with collective decisions and therefore reduces the role of emotions and experience in individual decisions. Adaptive theories suggest that economic decisions are not only based on the present, but also on expectations for the future, which in turn are based on past experiences. For example, the theory of classic bidY and demand would say that consumers would behave in some way if gasoline prices were $ 3.50 per gallon (3.79 liters). On the other hand, the theory of adaptive expectations suggests that consumer behavior will vary depending on whether consumers believe that gas prices are stable, on the way down or on the way up.
