“…Furthermore, autonomic nervous system responses can also distinguish among emotions, as reported by Ekman [23]. Previous studies [24][25][26][27] demonstrated that foods or food cues that were liked or disliked by participants elicited differential responses of the ANS as well as different emotional responses measured by facial expressions. It was concluded that autonomic responses provide additional information on food preferences relative to more traditional hedonic tests.…”

• We measured sensory-specific satiety with autonomic nervous system responses and facial expressions.• Consumption of the test meals resulted overall in increased heart rate, reduced skin conductance and skin temperature, as well as intensified disgusted facial expressions.• Skin conductance and skin temperature reflected effects of sensory-specific satiety.• Sad and angry facial expressions showed effects of sensory-specific satiety. a b s t r a c t a r t i c l e i n f o As a food is consumed, its perceived pleasantness declines compared to that of other foods. Although this phenomenon, referred to as sensory-specific satiety, is well-established by means of measuring food intake and pleasantness ratings, this study was aimed at gaining more insight into the mechanisms that underlie such cognitive output behavior using two measures used in (food) emotion research, namely Autonomic Nervous System (ANS) responses and facial expressions. Twenty-four healthy female participants visited four times in a hungry state, in which they received 4 different semi-liquid meals (2 sweet and 2 savory) delivered via a time-controlled pump leading to sensory-specific satiety. Before and after the meals they were presented with a sip of all four different test meals where ANS responses (heart rate, skin conductance and skin temperature) and facial expressions were recorded. As expected, pleasantness ratings showed a significant decrease after eating the same meal or a meal similar in taste (sweet or savory) (p b 0.001), and less decrease after eating a meal with a different taste. In general, consumption of the test meals resulted in increased heart rate, reduced skin conductance and skin temperature, as well as intensified anger and disgusted facial expressions (p b 0.05). In addition, skin conductance, skin temperature, sad and angry expressions also showed effects reflecting sensory-specific satiety. In conclusion, ANS responses and facial expressions indicate that sensory specific satiety of foods 1) not only reduces the food's pleasantness but also arousal and 2) are possibly mediated by changes in food emotions.

“…As mesmas medidas foram investigadas com alimentos previamente definidos como saborosos ou não, mostrando comportamentos autonômicos distintos em cada situação de consumo (de Wijk, Kooijman, Verhoeven, Holthuysen, & Graaf, 2012). Em outra pesquisa, a atividade elétrica dos músculos faciais foi utilizada, além da atividade elétrica neural e da condutância elétrica da pele, para investigar a influência de gênero e etnia no contexto do consumo de serviços (Boshoff, 2012).…”

Resumo A aproximação do marketing com a neurociência tem gerado expectativa tanto na academia quanto no mercado, em especial na última década. Apesar do interesse e das promessas de resultados, lacunas de conhecimento neurobiológico são percebidas acerca de formas de coleta e análise de dados. Este estudo apresenta e compara algumas ferramentas neurocientíficas que são fundamentadas em respostas não cognitivas do cérebro humano. A coleta e a análise de biomarcadores, como hormônios e níveis de atividade elétrica muscular, podem ser utilizadas em pesquisas de comportamento humano relacionadas ao consumo ou em outras interações com ações de marketing. A metodologia de aplicação dessas ferramentas, medidas resultantes e possíveis interpretações de comportamento também são discutidas, com ênfase em futura agenda de pesquisa.

“…Traditional methods reflect conscious processes, whereas consumer acceptance and product liking may be based on the unconscious processes as well. These unconscious processes may be measured using implicit physiological and behavioral measures (de Wijk et al, 2012).…”
