Document Summary
Motivation: a general term for a group of phenomena that affect the nature, strength and persistence of an individual"s behaviour. Regulatory behaviour: a behaviour that tends to bring physiological conditions back to normal, thus restoring the condition of homeostasis (eating, drinking, hunting, shivering, building a fire, and putting on a warm coat) Homeostasis: the process by which important physiological characteristics (such as body temperature and blood pressure) are regulated so that they remain at the optimal level. System variable: (the characteristic to be regulated) the variable controlled by a regulatory mechanism (eg. temperature in a heating system) Set point: the optimum value of the system variable in a regulatory mechanism. The set point for human body temperature, recorded orally, is approximately 37degrees c. Detector: in regulatory process, a mechanism that signals when the system variable deviates from its set point. Correctional mechanism: in a regulatory process, the mechanism that is capable of restoring the system variable to the set point.
