What term refers to the regular repetition of an acquired behavior pattern?

The term that refers to the regular repetition of an acquired behavior pattern is habit. A habit is a behavior that has been repeated so often that it becomes automatic or ingrained over time. This regularity is what distinguishes habits from other behaviors; they typically occur without the need for conscious thought and can significantly shape daily routines and lifestyle choices.

In contrast, while a routine can also involve repeated behaviors, it may not necessarily be automatic or ingrained, as routines can change more readily based on external circumstances. The term practice usually refers to the act of doing something repeatedly to improve a skill or proficiency, rather than the habitual nature of the behavior itself. Custom signifies traditional practices or behaviors that are culturally established, which may not reflect personal, individual habits. Thus, habit accurately captures the essence of an acquired behavior pattern that is regularly repeated.
