The zone of potential development: implications for intelligence testing in the year 2000

The emphasis of this paper is the practice and interpretation of intelligence testing of educable retarded children. The current and future state of intelligence testing are in terms of three criteria: their predictive, diagnostic and remedial functions. In the first section we consider individual testing formats within a framework of Vygotsky's theory of potential development and the underlying assumptions of that theory concerning task analysis and transferring of training. In section two, we consider the social nature of the testing situation and the degree of contextual support provided for the learner. In the final section we consider Neisser's distinction between academic intelligence and everyday thinking with particular reference to the life adjustment of mildly retarded citizens
