Abstract:
The method of measuring a subject's working memory, substantially free of bias from cultural and educational experience, to determine the subject's overall cognitive ability (â€œgeneral intelligenceâ€ ), including the steps of:(a) presenting an attention-demanding task to the subject, which engages the subject's working memory processes, and, simultaneously; (b) measuring the subject's behavioral responses to the task and neuroelectric activity at the subject's scalp using a set of electroencephalograph (EEG) electrodes and amplifier and analog/digital(A/D) converters to provide a set of digital data representing the subject's behavioral responses and neuroelectric activity in response to the task; (c) in a computer system, comparing the subject's digital data representing behavioral responses and neuroelectric activity in response to the task to a set of digital data representing the behavioral responses and EEG derived neuroelectric activity responses of a normal group to the same task; and (d) displaying the subject's overall cognitive ability score or scores based upon the comparison of (c) with the normal group.
