CHAPTER 1Study ContextWhen people see other people yawning, that person will also be yawning. Do human beings realize this situation? Sometimes, people yawn not because they feel sleepy, but simply because they are influenced by others who see them yawning at that moment (Giganti & Zilli, 2010). This situation is called contagious yawning. Contagious yawning means that when people yawn, they will automatically transfer it to other people who see them yawn and make those people yawn too (Yoon & Tennie, 2010). Contagious yawning occurred because a human has the ability to imitate the behavior of other people. Mirror neurons in the human brain have the ability to copy what others are doing (Keysers, 2007). This revealed that humans can imitate the behavior of other humans. During human and human interaction, they automatically imitate their interaction partner such as in speech accent, posture, gestures, and mannerisms (Lakin, Jefferis, Cheng, & Chartrand, 2003). This is demonstrated by numerous research already conducted. During treatment periods in the psychotherapy session, the patient will copy the therapist's posture (Ramseyer & Tschacher, 2008). This research demonstrated that the patient imitated the therapist. Other research conducted on women regarding eating showed that, among eating partners, another person imitated their eating partner by taking a byte at the same time as their eating partner (Hermans et al., 2012). Here mimicry can change people's actions. Human behavior regarding eating differs from person to person in how they consume food. A person's eating rate can be one of the important aspects of eating behavior. Time constraint could be one of the factors influencing the speed of consumption.
