On the level of developmental psychology the Gestaltkreis teachings correspond to Jean Piaget's observances on the development of the early childhood structures of perception, attitude and thought. In continual assimilation and accommodation processes, the motor cognitive and the emotional development work together and determine each other. The development of the senses, the continually differentiating thought and comportment structures, and the experience of space and time are, for Piaget, the prerequisites for developing the ability to symbolize. Compatible with this are the theories of development in depth psychology, where the main emphasis is on early childhood experience with the people with whom one has relationships and where the condition for a healthy development is a happy relationship with the person to whom one relates most closely (Balint, Mahler, Ericson, Winnicott, Kohut and Kernberg).
