1. Replicating Diemand-Yauman (2010)
You are now going to take part in a replication of a recent study by Diemand-Yauman (2010).

2. Instructions
Instructions: Scientists have recently confirmed the existence of three life forms from the planet Blangantz that have actually settled on planet earth. Although the scientists have not yet released actual pictures of these creatures, they have released lists of basic characteristics and behaviors of these creatures to the public.
Task: In a moment, you will be given the list of characteristics. You have 90 seconds to learn the information from these lists for later follow-up questions.

3. Procedure
You have 90 seconds to learn the information.
Now count backwards in 3s, from 42. Once you reach 0, wait for the next instruction.
You now have two minutes to answer the questions relating to the different alien species, on the handout provided.
Let’s see how many you got right…

5. Diemand-Yauman (2010) - Results
Task: Once we have collected the data, calculate the mean % and range, for both conditions.
Diemand-Yauman found the following:
Condition 1 – 72.8%
Condition 2 – 86.5%
Task: Once you have collected and analysed the data, as a group, consider the four questions at the bottom of page 1.

6. Conclusion
Once you have seen the stimuli given to both conditions, consider the following questions:
What conclusions can we draw from the data?
Do the results of our replication support Diemand-Yauman’s (2010) results?
Suggest a theory that could explain the data, why is it that one condition performed better than the other?
Were there any problems with our replication (for example, uncontrolled EVs)?
