interactionist view of intelligence

the view that intelligence always develops as an interaction between biological dispositions and environmental conditions and that it is difficult or impossible to separate the contributions of these two factors. Interactionists point out that genes always express themselves (manifest their effects in an individual) through a given set of environments and that the expression of the genes may be different as a function of the environment in which they are expressed.

decompression sickness

decompression sickness

an adverse effect of rapid movement of a body from an environment of high pressure to one of lower pressure, resulting in the formation of nitrogen bubbles in the body tissues. The circulatory system is particularly sensitive to the effect. Neurological consequences may include loss of consciousness, convulsions, paresthesias, and damage to the brain and spinal cord. A form of decompression sickness that affects the cardiopulmonary system and may lead to circulatory collapse is called the chokes; it is characterized by discomfort underneath the sternum and coughing on deep inspiration. When decompression sickness affects mainly the bones and joints, it is called the bends.
