Two Weeks Later
in a Normal Classroom
Both surveillance and the
expectation of an extrinsic reward
would decrease the amount of

3. Result
Findings
Sex does not effect the experiment
condition significantly
No significant differences between high
and low surveillance
Extrinsic incentives may undermine
children’s instrinsic interest
Being observed decrease
interest in the task
4. Beyond the Result
On extrinsic rewards
On adult surveillance
Agrees with previous studies
(Lepper et.al., 1997; Greene & Lepper, in press)
Against the generality of basic
phenomenon
Agrees with self-perception

SUGGESTIONS
Further Research
Practical Implementaion
- Effects regarding
the level of
surveillance
Reconsider the use of
extrinsic incentives and
periodic surveillance as a
controller and
manipulate behaviour in
schools
- Effect of face-toface monitoring
Exceptions
- Extrinsic reward
is allowed for
activities in
which students
are less
interested
5. Limitation
No measures of pre-experimental
interest in the target material
However, relevant pretest data of the
materials at the same school are available
The result of the experiment seemed not to work in
cases where initial intrinsic motivation is little
