Order effect


core definition

Order effects occur in a succession of social psychological experiments where the earlier treatments may impact on later treatments.


explanatory context

Order effects occur in social psychological experiments where one treatment follows another. Earlier treatments can themselves efffect later ones.

 

Randomising treatments to a group of subjects is a possible way of overcoming order effects. Alternatively the same subjects could be tested several times under different conditions in order to counterbalance the order effects.

 

Order effects are usually seen to fall into one of two categories.

 

First, practice effect where there is an improvement in performance with practice.

 

Second, fatigue effect, where there is a reduction in performance due to tiredness or boredom
