Companies are seeking new methods of market expansion and increasing brand ethics. The aim of the study is to determine the main factors affecting the consumers observation and preferences of the brand type, and to assay their purchase attitude and behaviours towards it. We constructed individualised stimulus lists of liked and disliked brand types from participators subjective pre-assessment. Participators then re-rated these visually presented brands whilst brain potential changes were recorded via electroencephalography (EEG). Other common methods in consumer neurology use array of techniques to measure aspects of autonomic nervous system activity. The ANS serves to regulate outlying body organs in a largely automatic and nonconscious fashion, and thus includes control of heart rate, sweating and salivation, respiration, digestion, and some various functions. Such measures are often commonly referring as “biometric technology,” and they have been employed for decades in psychophysiology laboratories to observe changes in individuals in response to prod that are emotional call, or tasks that require variations in mental effort.
