Choice and Intrinsic Motivation (Patall et al,. 2008)




I saw this sign half way up a mountain path in China. I thought this picture was relevant because it symbolizes how providing choice is not always as straight forward as it seems.

Take a moment to meet the author by following the link on her name.

This is another article from a learning theories course.  I find reading about motivation, well, very motivating. It gives me new ways to look at my own motivations and how they are enhanced or repressed, probably unwittingly in courses that I take.

This meta-analysis was conducted on 41 studies.

Below are brief descriptions of two theories that shed light on the effect of choices on intrinsic motivation:
1.      Self determination theory proposes that providing the context for students to satisfy their needs for autonomy, competence and relatedness will enhance their intrinsic motivation (Ryan & Deci, 2000).  Providing choice may be the most obvious way to support a person's experience of autonomy (p. 271).
2.      The self-regulatory perspective (Baumeister, Bratslavsky, Muraven, & Tice, 1998) proposes that "all acts of choice or self-control are effortful and draw on a limited resource that can be depleted, analogous to a source of energy or strength (p.272). If the choices are difficult (important/meaningful) or many they may result in a type of fatigue called ego-depletion, where the self-regulating resources are over-used, and a decrease "in the capacity to initiate activity, make choices, or further self-regulate" (p.272).
 
Some different ways that choice can be presented that may affect the strength and direction of the effect include the type of choice, the number of options in a choice, and the presence of an external reward.  
 
I. Type of choice

Three types of choices that support the students' autonomy include:
1.    Organizational autonomy (e.g., students help set seating arrangements and determine classroom rules)
2.    Procedural autonomy (e.g., students help decide how competence will be demonstrated)
3.    Cognitive autonomy (e.g., allow students to generate their own solutions to a problem) (p.273).

Results:
The results showed that ALL types of choice had a significant positive effect on intrinsic motivation as proposed by Deci and Ryan's self-determination theory (p. 294).

There has been question of whether meaningful choices (e.g., about method, pace and goals of the course) would have a different impact than non-meaningful choices on intrinsic motivation (IM).
  
Results:
The non-meaningful, instructionally irrelevant choices had the greatest positive impact on IM.  This may be because the students believed the instructionally relevant part of the task had a valid reason behind it so they were more willing to accept having no choice. The instructionally irrelevant choices  may still provide an opportunity for students to express their individuality (p. 295).

I think that meaningful choices actually sound like an operational definition of constructivism or student-centred learning, e.g., giving choices about method, pace and goals of the course. When considering whether constructivism is effective perhaps we should be looking at the literature on the impact of giving students choices. 
II. Number of choices


Within a given timeframe, if someone is given too many choices to make he/she becomes overwhelmed.  This is an example of ego-depletion and motivation decreases. On the other side of this argument, if you give someone too few choices then s/he may feel that s/he doesn't really have a choice and motivation does not increase as it could (p.273).  So what is the magic number of choices to achieve the best results?

Results:
“One of the most robust findings in the meta-analysis was that the total number of choices moderated the effect of choice on intrinsic motivation. Choice had the greatest effect when participants chose a single option from a list of options and did so repeatedly, as opposed to making just a single choice or multiple choices from a single list of options. Similarly, the largest positive effect of choice on intrinsic motivation was found when participants made two to four choices in a single experimental manipulation compared to when only a single choice or five or more choices were made” (p. 295).  


III. External rewards

External rewards are known to reduce intrinsic motivation to the extent they are seen as controlling (p. 273). This topic was addressed in my first posting. The results may vary depending on how the person's culture values individual choice. The results may also vary according to age of the participants as well.

Results:
“Specifically, the effect of choice was essentially zero when a reward external to the choice manipulation was provided compared to when participants chose the reward they would receive or when no reward was involved.” (p. 295)

“…as long as individuals have some control over the reward, it is not perceived as controlling, and the positive effect of choice on motivation remains” (p. 296).


Implications for the use of choice in the real world
1.    “It is important that a choice not be a laborious decision” (p.297).
2.    “Similarly, more choices, and possibly more options, may be better than fewer, but only up to a point (p.297).
3.    When it is not possible to provide a choice than it is important not to appear controlling.  Providing a choice that is not really a choice, i.e., including pressure to pick a particular option, or the alternatives are not very attractive, then the result will likely lose the benefit of having a choice.
4.    Likewise when an external reward is also provided with the choice, the positive effects may disappear. 

The article includes other discussions about how intrinsic motivation is measured, how the control condition was treated, and the limitations to generalizability of the meta-analysis due to confounding variables. It is important to remember that the results of a synthesis should not be interpreted as cause and effect statements but rather an association (p. 297).

Psychologist Barry Schwartz takes aim at a central tenet of western societies: freedom of choice. In Schwartz's estimation, choice has made us not freer but more paralyzed, not happier but more dissatisfied.
