Lev Semionovich Vygotsky, 1896-1934, was a Soviet psychologist who was active in a number of fields during his academic career, such as the psychological analysis of art and fables, child psychology, problems of deaf and retarded children, and the psychological analysis of brain-injured adults (Vygotsky). His work on language and linguistic development is based on his supposition that higher cognitive processes are a product of social development (Vygotsky).

(interpsychological) and then inside the child
(intrapsychological). This applies equally to voluntary
attention, to logical memory, and to the formation of
concepts. All the higher functions originate as actual
relationships between individuals" (Social).

Therefore, full development of the ZPD depends upon full social interaction, in other words, the range of skill that can be developed with adult guidance or peer interaction exceeds what the child can be attain alone (Social).
Vygotsky attempted to explain consciousness as the end product of socializat...
