 Within-subjects designs | -also called repeated measures designs -matched-subjects designs |
| Advantages of within within-subjects designs | -need fewer Ps (more efficient) -can study change over time -reduces random variation -no confounds with individual differences |
| Disadvantages | -sometimes impossible -order effects (see below) |
| Order effects | a confound created by changes in Ps that result from repeated exposure to IV levels |
| Practice effects | getting better if test is done over and over again |
| Fatigue effects | you deteriorate in your performance over time, if you make someone do it over and over again they will get tired and worn out |
| Sensitization | being aware of what is being tested |
| Carryover effects | effects from previous treatments may still be present when presenting new treatment (drug trials) |
| Counterbalancing | presenting levels of IV in different orders to different Ps |
| Complete counterbalancing | -include all possible orders of conditions -Ps can either go to condition A,B,C, or D |
| Latin squares design | each condition appears in each position once and each conditions precedes and follows another condition once |
