- Developmental Task
Erikson proposed that the developmental task of the infant is to form a sense trust. Infants learn to trust when their needs are being met. The confidence that their needs are met primarily results to trust development. Hence, rhythm of the care should be familiarized by infants as it gives them the feeling of being able to predict what will happen and gives life some consistency. Aside from that, the one caring for the infant plays an important role. Active interaction with the child promotes trust. Inability to develop the developmental task during the infancy period would result to mistrust which will be brought up until the child meets the sense of trust.
