Motivation and cognition Intrinsic and extrinsic motivation -Deci and Ryan’s cognitive evaluation theory “…external rewards often undermine intrinsic motivation... Essentially, feeling bribed by, or pawn to external reward contingencies...can decrease the extent to which an originally interesting or enjoyable activity continues to be experienced as self-rewarding.”

Variables that interact with intrinsic/extrinsic motivation: Personality – High versus low achievers Tauer and Harackiewicz (1999) Measurement of performance Time spent on task or the “Free-Time Paradigm” versus performance on task. Weirsma (1992) Type of task Pleasurable tasks vs. functional tasks
