Expectancy and Repetition in Task PreparationWe studied the mechanisms of task preparation using a design that pitted task expectancy against task repetition. In one experiment, two simple cognitive tasks were presented in a predictable sequence containing both repetitions and non-repetitions. The typical task sequence was AABBAABB. Occasional violations of this sequence allowed us to measure the effects of valid versus invalid expectancy. With this design, we were able to study the effects of task expectancy, task repetition, and interaction.
