Motivation a general term for a group of phenomena that affect the nature, strength, or persistence of an individual"s behaviour. Pleasant/unpleasant approach or avoidance (appetitive vs. aversive) Regulatory behaviour a behaviour that tens to bring physiological conditions back to normal, thus restoring the condition of homeostasis. Homeostasis the process by which important physiological characteristics (body temp and blood pressure) are regulated so that they remain at their optimum level (internal regulation) System variable the variable controlled by a regulatory mechanism. Set point the optimum value of the system variable in a regulatory mechanism. Detector in a 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. Negative feedback a process whereby the effect produced by an action serves to diminish or terminate that action. Regulatory systems are characterized by negative feedback loops.
