The Development of External Means of Communicative Orientation

Abstract

That human activity is mediated by signs is one of the key postulates of the cultural-historical theory of the development of the mind. The tools and sign systems mediating activity are becoming increasingly numerous and are in a continuous process of transformation and evolution. Accordingly, ways of transforming mental processes are also evolving. Specialists working in the mainstream of the sociohistorical approach analyze phenomena of "remediation," exploring their practical relevance for psychological diagnoses and correction (Cole, 1989).
