The null hypothesis states that every group of participants will have no significant difference in the number of expected and unexpected objects recalled.
Method section:
The independent groups design was used for this experiment. The reason is that this experimental design is not as time consuming as the matched pairs. This design also avoids order effects. Order effect is when a person is involved in the same test several times which causes them to get tired and fed up, as well as becoming wise to the requirements of the experiment. The independent variable changed were the pictures that had the expected or the unexpected objects. The controlled variables were giving both groups the same amount of time to look at the picture. The dependent variables were the number of objects recalled by the participants.
