Abstract
The present invention uses a personal computer 180 with an A/D converter 184 and a hard disk drive 182 to record the electroencephalographic (EEG) activity of a subject 192 during a commercial and to record event related potentials (ERP) during commercial evaluation sequences subsequent to the commercial. The EEG is analyzed by a signal processing computer 205 for alpha and beta frequency amplitude content to determine attention cognition of the commercial. Different commercials for the same product are compared using overall attention and cognition ratings. The ERP is analyzed to determine the amplitude and latency of the ERPs potentials produced by stimulus events in the evaluation sequences. The ERPs are filtered and the peak amplitudes and latency measured. The amplitude and/or latency determines the understanding of the commercial, the value of the product, the intent to buy the product and the memory of the product. By computing overall results for each commercial different commercials can be compared. The effectiveness the commercial can be compared to a reference product and a well known local price providing additional information concerning the product to the advertiser.
