Abstract

Systems and methods of employing experimental tasks, neurological and physiological recording devices, and a sequenced process of data acquisition and analysis to produce measurements of pre-verbal and pre-conscious brain processes. An array of measurement devices are connected non-invasively to an individual (the subject). The subject experiences one or more external stimuli via any combination of senses, including visual, auditory, tactile, olfactory, and/or gustatory. Experimental tasks, data acquisition, analysis, and/or presentation steps are processed to ascertain the subject'"'"'s pre-verbal and pre-conscious responses to the external stimuli, including attentional triggering, emotional valence and arousal, interest, engagement, and activation of higher cognitive processes such as memory, preference formation, and decision making.
