A method for detennining whether a subject has knowledge of a stimulus is described. The method includes generating a sensory signal corresponding to the stimulus for receipt by the subject, and collecting a cerebral indicator signal involuntarily generated in response to the subject processing the sensory signal. Identifying whether degrees of freedom in the cerebral indicator signal of the subject either increased or decreased is also completed. It is determined whether the subject has knowledge of the stimulus depending on whether the degrees of freedom increased or decreased. In addition, the method associates knowledge of the stimulus with the subject if it is determined that the subject has knowledge of the stimulus. |
