Hello!

We're starting IAs this week. My teacher gave us a list of possibilities and told us to pick one, then over the weekend find who did it and turn in the original study. My group picked one with the following description:

"First impressions and Primacy effects: ask participants to score a person’s maths test and then estimate the overall score on that person on Maths ability: Group A have correct answers first, then incorrect. Group B have incorrect answers first, then correct. Group A will estimate a higher score than Group B."

I have searched and searched, but the only place I can find anything resembling this is on various IB Psychology teachers' websites as a possible IA topic. The reason that I think that this may not have been an original experiment is that most of the other descriptions had a few citations (name and year), but this one doesn't. I initially thought it was an oversight, but no one is listed on any website that I've found.

So, any insight or suggestions?

Thanks,
Rachel

It seems like what you've investigated is a combination of two cognitive biases: Asch's original primacy effect experiment and the fundamental attribution error.  You will do fundamental attribution error as it's part of the syllabus (look up the game show study by Ross, it's on the wikipedia page).  Hopefully that gets you started, there's another link below.  If you need help getting the original papers feel free to ask .

I am actually about to start my Psychology SL IA and I have some ideas. I am SL and as I am informed, for SL students it is only allowed to find an experiment and replicate it in order to check the validity or to see if it can be applied to high school students for example. Our teacher also advised us to do something connected to memory as it is easiest to conduct.
My question is where on the Internet I can find good quality psychological experiments suitable for IA and replication in school settings?
I am sorry that I can't introduce some new variable, no really much space for creativity
