Carryover Effects (3 of 4)

next previous
Carryover effects can also be asymmetric. Consider the following table of means. 
                 Condition


Order             A1          A2
A1 given first     8
A2 given first                 5
 
A1 given second    10
A2 given second               15

Notice that performance in condition A1 is only two points (10 - 8) better if it follows condition A2 than if it is performed first. Compare this with performance in Condition A2which is 10 (15 - 5) points better if it follows condition A1 than if it is performed first.
