This study aimed to examine the effects of individuals’ intentional imitation of others’ blink on the former’s impression about the latter. The study addresses the understudied aspect in the existing research—the impact of imitation on the impressions of others when experimental participants are also imitators. The experiment was conducted online with 230 participants divided into two groups: a blink-imitation group and a non-imitation group. Participants in the first group imitated the blinks of individuals in the video, and their impressions about those individuals were rated. This procedure was performed four times with facial videos of different individuals. The non-imitation group followed the same procedure, except that the participants were instructed to keep looking at the eyes of the individual in the video. The experiment showed that the blink-imitation group had a better impression about the imitated individual than the non-imitation group. This result indicates that intentional blink imitation can enhance impressions of others and has potential applications in various interpersonal assistance situations, such as counseling.
