• Domestic objects are used at regular time intervals in the day to day life
• Usage durations and the frequency of use are varied
• “Human behaviours in constant contexts recur, because the processing that initiates and controls their performance becomes automatic”
• “Frequency of past behaviour reflects the habit strength and has a direct effect on future performance”
