A Triarchic Theory of Human Intelligence

Abstract

The triarchic theory of human intelligence provides a broader basis for understanding intelligence than do many, if not most theories of intelligence. The theory is called “triarchic” because it consists of three parts. The first part relates intelligence to the internal world of the individual, specifying the mental mechanisms that lead to more or less intelligent behaviour. This part of the theory specifies three kinds of mental processes that are instrumental in learning how to do things, planning what things to do and how to do them, and in actually doing the things. The second part of the theory specifies at what point in a persons’ experience with tasks or situations intelligence is most critically involved in handling of those tasks or situation In particular, this part of the theory emphasises the roles of dealing with novelty and of automatising mental processing in intelligence. The third part of the theory relates intelligence to the external world of the individual, specifying three kinds of macroprocesses — adaptation, selection and shaping — that characterise intelligent behaviour in the everyday world. This part of the theory thus emphasises the role of environmental context in determining what constitutes intelligent behaviour in a given milieu.
