Passage Two

The component of the healthy personality that is the first to develop is the sense of the trust. The crucial time for its emergence is the first year of life. As with other personality components, the sense of trust is not something that develops independent of other manifestations of growth. It is not that infants learn how to use their bodies for purposeful movement, learn to recognize people and objects around them, and also develop a sense of trust. Rather, the concept "ense of trust" is a shortcut expression intended to convey the characteristic flavor of all the child’s satisfying experiences at this early age. Or, to say it another way, this psychological formulation serves to condense, summarize, and synthesize the most important underlying changes, which give meaning to the infant’s concrete and diversified experience.
