Final answer:
Individuals typically become aware of their sexual orientation in early adolescence, during which time they go through significant physical and psychological development, forming a deeper understanding of their identity.
Step-by-step explanation:
The question seems to be focused on when individuals become aware of their sexual orientation. Research indicates that awareness of sexual orientation typically occurs in early adolescence. This is a time of significant growth and change where individuals start to understand their identity more clearly, including their sexual orientation. Developmental stages in a person's life, such as moving from adolescence to adulthood, involve both physical and psychological changes and challenges. While infants are primarily focused on basic reflexes and forming attachments, adolescents begin to develop a deeper understanding of complex aspects of their identity, including sexual orientation.
