A behavioural response or practice that is established by the individual frequently repeating the same act. The process is called habituation, and the more a person is exposed to a particular stimulus, the less is he or she aroused by it. People may also become habituated to certain drugs, requiring more and more of a substance to produce the same e?ect – a process known as TOLERANCE.
n. a sequence of learned behaviour occurring in a particular context or as a response to particular events. Habits are often the result of *conditioning, are performed automatically and unconsciously, and reduce decision-making. Habits, once established, often persist after the original causal factors no longer operate. Behavioural psychology is based on the premise that one form of conditioning can be replaced by another.
