Method For Training Material Evaluation With Method Of Eeg Spectral Estimation

US Patent:
5339826, Aug 23, 1994
Dec 9, 1991
Appl. No.:
Albert L. Schmidt - Murrysville PA
Ellen K. McKinley - Monroeville PA
Lewis F. Hanes - Pittsburgh PA
Michael R. Morris - Finksburg MD
Patrick J. McKenzie - Sykesville MD
Paul H. Haley - Monroeville PA
Westinghouse Electric Corp. - Pittsburgh PA
International Classification:
A61B 50484
US Classification:
The invention is a method and apparatus in which student EEG measurements are made during the videotaped presentation of training materials. Alpha (8-12 Hz) and beta (16-24 Hz) activity present during segments of the material directed to a learning objective are used to determine attention and cognitive activity during the training material. An increased level of attention relates to increased understanding of the material. An increased level of cognitive activity relate directly to incorrect understanding of the material. Evoked potential responses are also measured in response to multiple choice questions on the learning objections presented subsequent to the training materials. A difference between midterm responses for correct and incorrect answers measures correct understanding of the subject matter of the multiple choice question. Comparing the alpha, beta and evoked potential results for a learning objective validates the indication of effectiveness if the results correlate. To evaluate the EEG spectra for varying length recorded signal segments and between individuals with different magnitude responses, the EEG signals are normalized and interpolated to the same length before a windowed FFT is performed the peaks in the FFT are then found.
