The Research of Knowledge Workers’Competencies Based on EEG Experiment of Mental Operations

摘要

The paper analyzes the limitation of the method to study the competencies. The differences between competencies of knowledge workers exist in the “therbligs” used in information process. Based on 191 questionnaires, advance the 9 common mental operations: metacognition, distinguishing, memory, transforming, imagining, character extracting, character integrating, reasoning and concretization. And the metacognition plays a role on planning, supervising and adjusting to the other mind operations. Then the paper designs a mental arithmetic experiment to compare the difference in the brain electric power spectrum and the brain electronic topographic diagram between the subjects of the different performance. And the paper further discusses the feasibility of the method to explore the competencies.
