Final answer:
During the infancy stage of trust vs. mistrust, important events include responsive caregiving to establish trust, development of motor and perception skills, and the onset of stranger anxiety and object permanence. By one year, infants typically begin walking and talking, representing significant developmental growth.
Step-by-step explanation:
Important Events During Infancy in the Trust vs. Mistrust Stage
The trust vs. mistrust stage is the foundational stage of Erikson's psychosocial development that occurs during infancy, which is the first year after birth. This stage is marked by an infant's dependency on caregivers to meet their needs effectively and consistently. Caregivers who are responsive and sensitive to the infant's needs contribute to the development of trust, helping the infant see the world as a safe and predictable place. Conversely, an unresponsive caregiver may foster mistrust in an infant, leading to anxiety and fears about the unpredictability of the world.
In terms of developmental milestones, around six months, infants generally begin to pick up objects, pull themselves into a sitting position, and develop sharper vision including color and depth perception. Vocal play increases, and two-syllable sounds may emerge. At this age, infants also start exhibiting stranger anxiety. Around ten months, infants show advances in motor skills such as crawling and may start to babble in patterns similar to speech. They also develop object permanence, understanding that objects continue to exist even when out of sight.
By the end of the first year, infancy is characterized by significant changes, with infants typically beginning to walk and talk. The first year is a time of rapid growth and development, laying the groundwork for future stages like autonomy versus shame and doubt, and later the development of self-concept.
