Abstract
The psychological impact of entertainment material, visual objects, brands and advertising, commercial communication, the response to an individual presenting a message, or to an individual seeking public office can be assessed using methods employing measurements of SSVEP or SSVER phase increase and gaze tracking of subjects in a variety of ways. Various psychological states may be analyzed in order to accurately predict success and to enable early modification in development stages of products or communication.

182. A method of quantitatively assessing at least one psychological response of at least one subject to at least one stimulus including the steps of:
-
(a) presenting the at least one stimulus to the at least one subject, the at least one stimulus having a sequence of audio, visual and/or audiovisual features that occur as a function of time; (b) obtaining, during the presentation of the at least one stimulus, electroencephalogram (EEG) signals and/or magnetoencephalogram (MEG) signals from at least one pre-determined scalp site on the at least one subject; (c) calculating steady state visually evoked potential (SSVEP) phase increase and/or steady state visually evoked response (SSVER) phase increase from said EEG and/or MEG signals to obtain output signals representing pre-determined psychological states of the at least one subject occurring as a function of time; (d) optionally combining the output signals from a plurality of subjects to obtain pooled output signals; and (e) analyzing the output signals and/or pooled output signals to quantitatively assess the at least one subject'"'"'s at least one psychological response to the at least one stimuli. - View Dependent Claims (183, 184, 185, 186, 187, 188, 189, 190, 191, 192, 193, 194, 195, 196, 197, 198, 202)

-
means for presenting the at least one stimulus to at least one subject, the at least one stimulus having a sequence of audio, visual and/or audiovisual features that occur as a function of time; means for obtaining, during the presentation of the at least one stimulus, electroencephalogram (EEG) signals and/or magnetoencephalogram (MEG) signals from at least one pre-determined scalp site on the at least one subject; and means for calculating steady state visually evoked potential (SSVEP) phase increase and/or steady state visually evoked response (SSVER) phase increase from said EEG and/or MEG signals to obtain output signals representing pre-determined psychological states of the at least one subject occurring as a function of time. - View Dependent Claims (200, 201)
