This is one of the most important parts of this course – I want you to work with your group to design a follow-up study to the Primacy Effect. Your instructor will share your ideas with the whole class, and you will vote on which one you would like to do for your final class project. As you work on this discussion, try to think about what other variable might influence The Primacy Effect. Let me give you a few example, though try to get creative with your group. Look at prior research and see if you can use some of their work as a follow-up to your study. Have fun with it! Okay, consider some ideas I was thinking about for a follow-up study (Personally, I would recommend the second or third idea, as there is a lot of research you could draw on about these topics, which would make Paper III much easier to write).
First, we keep on the positive and negative conditions only (dropping the mixed condition) Then, we alter the type of charity. Identical to Study One, we have “Casey” tell her friends to post one word that best describes here. Six of her friends do so, with some conditions listing them positive to negative and other conditions listing them negative to positive. However, in half of the conditions, Casey might add a final post, adding the following: “You know, this list reminds me of the primacy effect from my psych classes, where the first few words in a list have the greatest impact on people’s perceptions. Interesting.” Casey would not add this explanation in the remaining conditions. This would give us four conditions (Positive Explanation, Positive No Explanation, Negative Explanation, Negative No Explanation).
A third idea might involve adding an emoji element to some of the conditions. That is, some conditions only get the usual positive words starting the list (or negative words) that we had in study one. However, or conditions get the positive (or negative) word plus an emoji that is in line with that word. Once again, this gives us four conditions: Positive Emoji, Positive No Emoji, Negative Emoji, and Negative No Emoji. Will the presence of an emoji matter? Please note that I think this idea is interesting, but there might not be a lot of research on emojis yet. That might make it fun (but challenging) to write about, but it is possible!
Finally, you can look at some participant characteristics if you like. You can measure how the participant age (young versus old) might impact decisions (though you need to recruit both old and young participants). You could see if participant gender interacts with the high versus low donation conditions. Just remember that if you choose a participant characteristic, you cannot draw cause-effect conclusions (since you cannot randomly assign someone to be old or young or to be a man versus a woman). That is why I would prefer that you manipulate some feature of the study so you can randomly assign people to one of the four different conditions.
As you can see, there are tons of ways to extend your original study. Work with your classmates to identify the one you like best, and then let your instructor know. Your instructor will take the consensus vote for the whole class and let you know what the study will be for study two. In this discussion, I want EACH of you to do three things. First, tell me which study you want to do (that is, which second independent variable you find most interesting. This can differ from those I suggested above). Second, give me a reference in APA format for one peer reviewed research article that has something to do with this second variable. This article does not have to involve the Primacy Effect at all, but it must have something to do with your second independent variable. Third, give me a hypothesis for what you expect to occur if your new independent variable is chosen for the class project. That is, tell me what main effect you would predict from this new IV
