In the next two units, I'm going to talk about psychology. Specifically, the psychology of motivation. Now, don't worry, this is not a psych course, it's a gamification course. But we need to fo cus in on psychology because it's central to what makes gamification effective. And if you think about gamification without digging into the mental processes that are going on in people who are involved in gamified services, you're going to miss a lot of the essential practices to do gamification effectively. So, particularly, we're going to talk about motivation. Motivation means you are moved to do something. It's what makes you do something versus something else or do something versus just sitting around doing nothing. Now, of course, we're talking psychology here so people don't entirely know what makes them do something. They might say, oh, well I did that because I felt like it. Or, I did that because someone told me to. But it turns out we have a lot of leeway, and the reasons that we do things can be fairly complicated, and not necessarily related to our experience. And they also may be counter intuitive. So, certainly people do things for rewards. You do things because someone says, if you go and compete you'll be the winner, you'll get a big trophy. Or, if you go and do a really great job at work in this job that you've got, at the end of the year you'll get a bonus, you'll get more money. Sure, those are things that motivate people and later on I'll get into more detail about what is the essence of those kinds of motivators versus some other kinds of motivators. But there are lots of things people do for very different reasons. First of all, lots of people work really hard at their jobs, care tremendous amount about there jobs even when those jobs don't pay very much. We've all talked to people who say, I love my job.I would do it for free. Well, what's that? And clearly we all do things for other reasons than rewards. Not everyone is participating in every competitive activity because they think they're going to win and get the trophy. We do things like sports, in part, because they're just kind of fun to engage in. So, there's a lot to motivation. And before I get into looking at it systematically, I'd like you to think about different ways that people could be motivated. So, I would ask you, pick some task that you might want someone to do and see if you can think of at least four different ways that you could try to motivate that person to do the task. They might not always work, but see if you can think about at least four different approaches you could take that would operate in distinct ways to motivate that person to take the action. Alright, hopefully you came up with some different ideas. Keep those in mind later on when I talk about intrinsic and extrinsic motivation and the different psychological theories that we're going to go through. And see which of them match up with the different motivators that you came up with.
