The
Effects of Four Kinds of Extrinsic Rewards on Intrinsic Motivation
S. Sakurai |
The
purpose of this study was to examine the Self Evaluative Motivation
(SEM) Model proposed by Sakurai (1984a), using four kinds of extrinsic
rewards: verbal, token, verbal-token, and only feedback from outcomes.
The control group received no rewards nor feedback. According to
the SEM model, the experimental and the control groups should select
the following tasks after getting each reward mentioned above. Four
experimental groups should more difficult tasks than the control
group because they have higher feeling of competence. The token,
the verbal -I- token, and the control groups should select more dissimilar
tasks than the verbal and the feedback groups because the former
groups have little feeling of self-determination. After exercises,
subjects were assigned lucky-puzzle tasks and given each extrinsic
rewards or feedback. Then they were asked which task they wanted
to try among four kinds of tasks. Most results supported the present
predictions.
