General session: Methods in food and eating studies

Schedule: Thursday 19th May 13:15 - 14:15 CET Virtual Room 2
Chair: Billy Langlet, Karolinska Institute, Sweden. 

13:15-13:30    Conscious and unconscious emotional response evoked by food appearance in children: a study based on automatic facial expression analysis and skin conductance response.
Noelia da Quinta, Ana Baranda and Iñigo Martinez de Marañon, AZTI, Spain
The codification of action units, emotions through facial expressions and the monitoring of the skin conductance response are appropriate methodologies to be used with children to study the conscious and unconscious response elicited by food samples.

13:30-13:45    The Effect of Virtual Reality on Eating Behaviours and Hunger: A Randomized Crossover Study.
Billy Langlet, Alkioni Blibi, Per Södersten & Cecilia Bergh, Karolinska Institutet, Sweden.
There was no difference in food intake between virtual and real meals, meanwhile the meal duratoin was significantly shorter in the virtual meals. There was no difference in hunger before and after the virtual meals.

13:45-14:00    An Attempt to Assess the Effects of Social Demand using Explicit and Implicit Measures of Food Experience.
Priya Sabu. TNO Soesterberg.
Explicit and implicit (EEG) measures were used to assess the impact of social demand on liking Japanese and Dutch food. Social pressure was too weak to increase liking of Japanese food, but the measures were sensitive to other variables of interest.

14:00-14:15    How Diet Composition Correlates with Cognitive Functioning - Application of Principal Component Analysis (PCA) to Nutritional Data.
Wanda Zarzycka, Warsaw University, Poland
PCA was used to aggregate the dietary data collected. Specific aggregates were analyzed in correlation with results from a cognitive task. These dietary patterns were found to be correlated with distinct effects on cognition.
