Fogel, Alan Dale | A relational perspective on the development of self and emotion | Begin with two premises. First, psychological experience always implies a connection, a relationship: with another person, with cultural tools or language, or with the natural environment. Life is a network of relationships. Second, psychological experience is always dynamic and changing. The sim... | 2001 | |
