Table 1 Results of the GLMM including the following fixed factors: condition (factor variable: yawning video stimulus = 1; control video stimulus = 0), attention level (numeric variable: number of seconds the woman looked toward the video stimuli), video sequence (factor variable: YC = 1, CY = 2), time period (factor variable: 09:00 am–12:30 pm = 1; 12:30–16:00 pm = 2; 16:00–19:30 pm = 3). The identity of the potential responders (Responder) was included as random factor
