At what stage does the categorical self begin to emerge in infants?

The emergence of the categorical self in infants occurs when they realize they are separate individuals. This developmental stage is characterized by infants beginning to understand themselves as distinct entities apart from others. They start to categorize themselves based on physical characteristics (such as gender and age) and other attributes, which are fundamental to their self-concept.

Recognizing their own reflection, forming emotional attachments, and developing language skills are all important stages of development but occur either alongside or after the realization of self as a separate individual. The understanding of being an individual forms the foundation for more complex self-recognition and categorization as they grow. This realization plays a crucial role in shaping their identity and influences their interactions with the world around them.
