What are the primary developmental tasks during infancy?

During infancy, the primary developmental tasks focus on the rapid growth and maturation of physical and sensory skills. Developing sensory and motor skills is pivotal during this stage; infants go through critical milestones such as grasping objects, crawling, and eventually walking. This period is characterized by the exploration of the environment through senses and movement, laying the foundation for future learning and development.

While language acquisition begins in infancy, it is not the primary task but rather an ongoing process that evolves over the first few years of life. Forming friendships typically develops later in childhood, as social skills and understanding of relationships mature. Improvement in logical thinking occurs much later in childhood, as cognitive development continues into the preschool and school-age years. Therefore, the focus during infancy is on the physical aspects of development, particularly through the enhancement of sensory and motor skills, making this the correct choice.
