2.3. Habit Habit has been defined by researchers from different perspectives. Neal et al [2011] defined a habit as a person’s psychological and learned disposition to repeat past behavior. Liu-Thompkins and Tarn [2013] defined habit as “a behavioral disposition that is exercised frequently and in which responses are triggered directly by contextual cues” (p. 22). In general, these definitions reveal that habit is not the same as behavior. Habit is a behavioral tendency and is gradually laid down in the procedural memory through repeated performance. Habit formation is strongly related to the frequency of previous behavior in a stable and recurring context [Shahet al 2014]. Overall, the online shopping habit can be viewed as an automatic behavioral response that is triggered by a situational stimulus without a cognitive analysis process because of the learned association between the shopping behavior and satisfactory results [Chiu et al 2012].
