​Electroencephalography (EEG)

EEG has a high temporal resolution (milliseconds), allowing researchers to identify in a millisecond time range the changes in the patterns of brain activity of individuals when they are exposed to different stimuli, such as advertisements, brands or products. When used alongside traditional market research techniques It answers the “why” beyond the “what”, evaluating cognitive processes such as attention, concentrated thinking, match/mis-match of events and arousal.

Can EEG inform us about emotions?

​Yes, EEG activity is modulated by the emotional valence of a stimulus, meaning we can deduce whether something is being perceived positively or negatively. This can inform us about consumer preferences at the implicit, unconscious level.

When to use EEG​

EEG should be used when you are interested in understanding how the brain implicitly or explicitly processes your brand, product or service. EEG will give you detailed information about the time course of this processing, telling you how early a product, brand or service is registered by the brain, and will inform you about the level of engagement with a product, brand or service,

Can it be done online?

No, EEG requires specialist knowledge to apply, analyse and interpret, and the equipment is not cheap meaning the electrodes are not readily accessible to the public.
