Resumen
This paper examines the influence of psychology in the area of human computer interaction and information technology in general. Cognitive psychology is critically examined and its shortcomings in guiding technological development outlined. As a possible alternative to the cognitive approach the Vygotskian psychological framework of activity theory introduced. This Russian developed theory may provide a more extensive basis for human computer interaction and holds some promise as a framework for the development of computer systems more compatible with the humans that use them.
