Intrinsic and Extrinsic

2. Types of Motivation
Intrinsic motivation: a desire to perform a behavior for its own sake.
Extrinsic motivation: a desire to perform a behavior due to promised rewards or threats of punishment.

3. The Experiment
Only preschoolers showing high interest in drawing during free playtime were selected for the research.
The children were randomly assigned to one of three conditions.

4. 1. Expected reward condition:
Children were shown a ribbon and told if they did a good job drawing, they could earn a ribbon and have their names put on the school honor roll board.
All students in this condition received the expected reward.

5. 2. Unexpected reward condition
Children were asked to draw without any mention of the awards.
Unexpectedly, at the end of the drawing period, all of these children were given the awards.

6. 3. Control condition
Children were asked simply to draw without promise or presentation of awards.

7. Results After this task, children were observed back in the classroom.
the amount of time they spent drawing during free play time was recorded.
Predict w/ a partner how long you think children from each condition would spend drawing during the later freeplay period.

8. The correct prediction…
Children from the expected-reward condition later drew less than children from either the control or the unexpected-reward condition
no significant differences were seen between the latter two conditions.

9. Overjustification Effect
Excessive rewards can undermine intrinsic motivation.
If you promise a reward for doing what one already likes to do, the person comes to see the reward, rather than the intrinsic interest, as the motivation for performing the task.

10. An example using adults:
In one experiment, adults who were paid to lose weight at first lost pounds faster than those who were not paid.
When the payments stopped, the paid subjects regained some of the lost weight.
Those subjects who had not been paid in the first place continued to lose weight.

11. What does this mean?
Rewards lead people to think that an activity does not deserve doing in its own right. Why else would someone offer rewards?
When rewards are withdrawn, people judge the activity as no longer worth doing.

12. Similarly, rewards can cast a shadow over romantic love.
Dating couples were asked to think of the extrinsic rewards (“she/he knows a lot of people”) or the intrinsic rewards (“we always have a good time together”) they obtained from going out with their partner.
When later asked to state their feelings, the couples who had thought of extrinsic rewards evaluated themselves as being less in love than did those who thought about the intrinsic rewards.

13. Do rewards inevitably undermine intrinsic motivation?
Rewards (money, praise, candy bars) can be used in two ways: to control us, or to inform us on how well we are doing in meeting the challenge of a particular task.
When rewards are used to control or manipulate, they are likely to undermine intrinsic motivation.
When rewards are used to inform, they may actually boost people’s feelings of competence and intrinsic motivation.

14. People are more likely to see unanticipated rewards as giving them information about their performance, since the reward was not presented at the beginning as a bribe.
Rather than emphasizing rewards from the outset to control a class or a child, perhaps teachers and parents might better use them occasionally as an unexpected bonus.
