Answer:
The answer is Trust vs. Mistrust and isolation, respectively.
Step-by-step explanation:
According to Erik Erikson, individuals must overcome a personal crisis in each stage of their lives in order to develop as functional members of society.
Erikson's structure of psychosocial development is divided into eight stages; Trust vs. Mistrust is the first one of them, appearing at birth, in which children must learn to trust adults. Failure to do so might result in isolation, later in their development.
