We examined the relationships among intrinsic and extrinsic motivational orientations, achievement goals, and intelligence beliefs for 202 3rdthrough 8th-grade children from K-8 schools. Analyses of age differences revealed substantial declines in intrinsic – but not extrinsic – motivation with increasing grade level. Intrinsic motivation was associated with mastery goals but unrelated to perfo...

Different types of icons can trigger different amount of extrinsic and intrinsic motivation to semi-literate users. The different motivational variables are also expected to have different amount of effect on the behavioral intention of the use of such users. Our study approaches these issues from two theoretical perspectives. Based on the theory of metaphor, we argue that an interface which co...

Recent research suggests that extrinsic rewards promote memory consolidation through dopaminergic modulation processes. However, no conclusive behavioral evidence exists given that the influence of extrinsic reward on attention and motivation during encoding and consolidation processes are inherently confounded. The present study provides behavioral evidence that extrinsic rewards (i.e., moneta...
