Attentional bias towards high and low caloric food on repeated visual food stimuli: An ERP study

Duraisingam, Aruna, Palaniappan, Ramaswamy, Soria, Daniele (2021) Attentional bias towards high and low caloric food on repeated visual food stimuli: An ERP study. In: 2021 43rd Annual International Conference of the IEEE Engineering in Medicine & Biology Society (EMBC 2021). . IEEE (doi:10.1109/EMBC46164.2021.9629882) (KAR id:91421)


Food variety influences appetitive behaviour, motivation to eat and energy intake. Research found that repeated exposure to varied food images increases the motivation towards food in adults and children. This study investigates the effects of repetition on the modulation of early and late components of event-related potentials (ERPs) when participants passively viewed the same food and non-food images repeatedly. The motivational attention to food and non-food images were assessed in frontal, centroparietal, parietooccipital and occipitotemporal areas of the brain. Participants showed increased late positive potential (late ERP component) to high caloric image in the occipitotemporal region compared to low caloric and nonfood images. Similar effects could be seen in the early ERP component in the frontal region, but with reversed polarity. Data suggest that both the early and late ERP components show greater ERP amplitude when viewing high caloric images than low caloric and non-food images. Despite repeated exposure to same image, high caloric food continued to show sustained attention compared to low caloric and non-food image.
