repeated measures Flashcards
1
Q
strength: individual differences are removed
A
ID between ppts in each condition removed, same ppts take part in all conditions, researcher can be more sure that changes to DV are due to IV, increases internal validity
2
Q
strength: requires fewer ppts
A
same ppts take part in all conditions, unlike independent measures
3
Q
weakness: order effects
A
when ppts take part in more than one condition, may perform worse in the second condition, or better in the second condition due to practice, may be lasting effects, lowers internal validity
4
Q
weakness: demand characteristics
A
may pick up on clues given off by the researcher, spend more time with researcher, change their natural behaviour to help or hinder research
