Experience has taught us that not all experiments are suitable to be replicated for the IB Diploma Psychology IA.  However, any of the ones below can be modified to suit.

The hyperlinks below are all of the original experiments, which saves you a lot of time.   The original studies can be hard to read, so focus on the abstract, the introduction, the results and the discussion.

Researchers often include a number of experiments or trials in the one report. You need to focus on just one experiment.  In deciding whether a study is suitable for the IA, ensure that you will manipulate one independent variable that has two conditions, that your experiment will produce two sets of either interval or ratio data and that you will be able to depict your results in a simple bar graph.
