There is something really cool about the ecological systems theory, but Lev Vygotsky and his socio-cultural theory are also very important. Vygotsky was a Russia developmental psychologist who died at the early of age of 38. He argued that cognitive growth occurs in a socio-cultural context and that it influences the form it takes. He also argued that a child’s noteworthy skills develop from social interactions with parents, teachers and peer groups.

He brought forward the idea that human development must be evaluated from four interrelated perspectives and they are: microgenetic, ontogenetic, phylogenetic and sociohistorical. Ontogentic development is the development that takes place in an individual over his/her lifetime. This is the major area of all developmental psychologists.

Microgenetic development includes changes that occur over brief periods of time like a child improving in his/her mathematical skills after solving same kind of problems for 2 weeks. Once these developments take place, a person grows up to be a fully functioning adult. Problems related to development must always be discussed with your psychologist. Never forget that!
