Two experiments were carried out in order to test the effects of task sequence on the speed of rule learning and problem solving. Expt. I involved numerical rule-learning teaks. One group of subjects waa presented with the tasks using a simpl-omplex sequence while another group was presented with the complex rather than the simple task initially. The simple-complex order resulted in a far superior performance. Expt. I1 teated the effect of taek difIioulty and task precedence using problem-solving tasks. Speed of problem solving wae not found to be significantly sffected by task order.These contrestig results were discussed in terms of hypothesis testing theory and learning hierarchies.
