Stage 1: Asocial

• • From birth to 2 months, infants produce similar responses to all objects, whether animate or inanimate ​
• • Towards the end of this period, infants show greater preference for social stimuli, (e.g.: a smiling face) and are more content around people ​
• • During this period, reciprocity and interactional synchrony play a role in establishing the infant's relationships with others ​
