From: Producing unexpected emotional expressions in others reduces one’s own agency
Trial sequence of Experiment 1. At the beginning and between trials, iCub maintained a neutral facial expression. Participants were asked to select between two objects (i.e., screwdriver or hammer) to show iCub. After a delay (300, 500, 800 ms), iCub displayed the corresponding expression: happy (screwdriver) or sad (hammer). In 20% of the trials, an accidental outcome occurred where iCub displayed a sad expression instead of the intentional happy one. Participants then estimated the perceived time interval between their action and iCub’s facial expression using a slider.
