EEG transitions in the learning process of simple tasks

The authors describe experiments in which subjects´ EEG (electroencephalogram) sequences were measured while engaged in a task in an ordinary laboratory without special electromagnetic shielding, to identify any dependence of the EEG transition process on differences in tasks, to identify features of the EEG which would be an index to the proficiency of the subject, and to obtain some correlation between the index and the task performance of the subject. Results of a calculation task and a manual pursuit tracking task are presented. In the case of the calculation task, the alpha-wave power was found to be increased in the learning process, while in the manual tracking task, the alpha-wave power showed little increase in the learning process. For the manual tracking tasks, a sort of correlation was found between the task performance and the alpha-wave power.<>
