Participants take part in both the control and experimentalconditions
Repeated measures Adv + Dis
Adv = No individual differences between groups. In the repeated measures design, as the participants in each condition are the same people
Dis = Demandcharacteristics may be a problem as they are more likely to guess the aim of the research if they take part in bothconditions,Differenttests may be needed (one of the tests might be ‘harder’ than the other becoming a confounding variable)
