Formation

Habit formation is the process by which a behaviour becomes habitual. As behaviours are repeated in a consistent context, there is an incremental increase in the link between the context and the action. This increases the automaticity of the behaviour in that context.[5] Features of an automatic behaviour are all or some of: efficiency, lack of awareness, unintentionality, uncontrollability.[6]

Habit formation is modelled as an increase in automaticity with number of repetitions up to an asymptote.[7][8][9]

Author John Tesh advises that it takes about 21 days to establish or break a habit.[10]

Habits and goals

The habit–goal interface is constrained by the particular manner in which habits are learned and represented in memory. Specifically, the associative learning underlying habits is characterized by the slow, incremental accrual of information over time in procedural memory[11] Habits can either benefit or hurt the goals a person set for themselves.

Goals guide habits most fundamentally by providing the initial outcome-oriented impetus for response repetition. In this sense, habits often are a vestige of past goal pursuit.
