The latent value of food has a great impact on customers’ feelings in purchasing and eating food. Our previous study revealed that the latent value of curry roux for home use induces an empathetic bond between people. When eating together, people need to communicate during the meal and complex operations are required. According to a recent study which investigated eating behavior and compared eating alone to eating together, the author explains that the reason of the gathering movement is to reduce uneasiness when eating together. We previously revealed that stirring and gathering movements (hereinafter referred to as Movements) induce comfort and an empathetic bond between people when eating curry together. To reveal the universality of this effect, we experimented on spaghetti, another dish requiring Movements. We conducted paired experiments (N=12) in two different eating styles; with and without Movements. Comfort was measured by biometric information, electrocardiogram, and by Kansei evaluation, Curve Drawing Method. Fork synchronization was also measured as an indicator of empathy. There were no differences in HF, LF/HF ratio, surface areas of the Curve Drawings and rate of fork synchronization between when using Movements and not using Movements. Movements when eating spaghetti did not have impact on comfort and empathy, in contrast to using Movements with curry. The interesting effect caused by Movements with curry may partially explain why it is eaten repeatedly as a national food.
