However, the maintenance and enhancement of intrinsic motivation depends upon the social and environmental conditions surrounding the individual. Deci and Ryan’s Cognitive Evaluation Theo...

This paper is a chronological survey, with no proofs, of a direction in categorical algebra, which is based on categorical Galois theory and involves generalized central extensions, commutators, and internal groupoids in Barr exact Mal’tsev and more general categories. Galois theory proposes a notion of central extension, and motivates the study of internal groupoids, which is then used as an a...

A new theory of motivation is described along with its applications to addiction and aversion. The theory assumes that many hedonic, affective, or emotional states are automatically opposed by central nervous system mechanisms which reduce the intensity of hedonic feelings, both pleasant and aversive. The opponent processes for most hedonic states are strengthened by use and are weakened by dis...

The present study examined the utility of two forms of measurement of intrinsic motivation in increasing the predictive validity of the theory of planned behaviour. Self-report questionnaires were administered to school pupils (n1⁄4 174), University students (n1⁄4 129) and adults (n1⁄4 157). The data were analysed using confirmatory factor analysis and regression analysis. Confirmatory analysis...
