Sensitivity to others’ emotional signals is an important factor for social interaction. While many studies of emotional reactivity focus on facial emotional expressions, signals such as pupil dilation which can indicate arousal, may also affect observers. For example, observers’ pupils dilate when viewing someone with dilated pupils, so-called pupillary contagion. Yet it is unclear how pupil size and emotional expression interact as signals. Further, examining individual differences in emotional reactivity to others can shed light on its mechanisms and potential outcomes. (...) In the current study, adults’ (N = 453) pupil size was assessed while they viewed images of the eye region of individuals varying in emotional expression (neutral, happy, sad, fearful, angry) and pupil size (large, medium, small). Participants showed pupillary contagion regardless of the emotional expression. Individual differences in demographics (gender, age, socioeconomic status) and psychosocial factors (anxiety, depression, sleep problems) were also examined, yet the only factor related to pupillary contagion was socioeconomic status, with higher socioeconomic status predicting less pupillary contagion for emotionally-neutral stimuli. The results suggest that while pupillary contagion is a robust phenomenon, it can vary meaningfully across individuals. (shrink)

We investigated the impact of situational awe on topic-specific interest and recognition memory for information presented in immersive planetarium films. Adult participants (N = 131) were recruited among science centre visitors who were going to view one of the films shown in the science centre’s planetarium. Participants responded to questions about prior knowledge, topic-specific interest in the film and background information before viewing one of the three planetarium films. After the film, they completed the topic-specific interest scale, epistemically-related emotion scales, (...) situation-specific awe scale, critical thinking disposition scale and a recognition task of the film contents. The results showed that during viewing planetarium films participants experienced awe, but the strength of this emotion varied among films. Additionally, situation-specific awe was strongly associated with another epistemic emotion, namely surprise. As for the recognition task performance, awe decreased error and nonsense detection, and increased false recognition of inferential statements. Finally, awe was found to substantially increase topic-specific interest. These results present evidence that awe has potential to prompt individuals to become more interested in science-related topics. (shrink)
