Lev Semenovich Vygotsky (1896-1934)

Lev Semenovich Vygotsky developed a theory of mental growth which emphasised the role of language, explanation, and interaction between different children, as well as the individual child's own play. "In play, a child is always above his average age, above his daily behaviour; in play, it is as though he were a head taller than himself." His work ranged from psychology to aesthetics.

At the University of Moscow, he studied linguistics, sociology, psychology, philosophy, literature and art. After graduating in 1924, he started his work on developmental psychology, education, psycho-pathology and primatology. 10 years later, he suffered an untimely death from tuberculosis.

One central theme in his work is what he calls 'the problem of consciousness' and 'the crisis in psychology'. How can the mind come to be aware of itself? He poured scorn on theories of psychology which either did not attempt to answer this question, or tried to do so with what he saw as an unscientific focus on the apparent needs of society. Such thoughts did not find favour with Stalin and the forces he led. Soon after his death, Vygotsky's name became unmentionable in Soviet psychology. His reputation was only re-established in the 1960s. But in his short working life, he led what seems to have been the first experimental study of the relation between language and consciousness, and what he calls the 'genetic roots' of this relation.

Another central theme in his word concerns the differences between individuals. He was interested in what has now come to be known as the 'nature/nurture' issue. Vygotsky was strongly on the nurture side. For Vygotsky, intelligence and ways of thinking are the products of the world in which the individual grows up. For the sake of their future development, children need to be given the right sort of information in an appropriate way at the point when they are best able to absorb it.

For Vygotsky, intelligence was a readiness to listen, and language was language, whether words were spoken out loud or just in the mind. In this respect, his thinking foreshadows that of Noam Chomsky a generation later.

Education would thus consist in an ongoing process of adjustment between teacher and child. Consciousness was based on a complex layering of different levels of awareness. Vygotsky distinguished between 'spontaneous concepts' which the child could discover from active exploration of the environment and 'scientific concepts' which the child needed to be taught. By this thinking, teaching should be based on the next stage in the child's development rather than on the current one. The purpose was to extend the child's current thinking, and provide a setting for the next, higher level of understanding.

Vygotsky is mainly known for Thought and Language, originally published in 1934 just after his death, translated into English in a highly abridged form less than half the length of the original Russian edition.

Piaget and Vygotsky knew of each others work, each clearly respecting that of the other, but disagreeing profoundly on various issues. Piaget thought language emerged from thought. From his studies of apes, Vygotsky thought language must have its own genetic roots. Chomsky would support Vygotsky on this. Vygotsky challenges Piaget's failure to explain the emergence of inner thought and scientific concepts. For Vygotsky, Piaget hugely exaggerates the scale and significance of children's egocentricity, and underestimates the complexity of what they need to learn - particularly about the social world.

Pigeon Post is designed to draw the child out in a process of creativity, revealing where he or she is at in exploring the worlds of literacy and arithmetic, but in a way that makes it fun to send messages, and relate to peers, friends and family.
