The current study aims to investigate whether threat or safety information presented by parents about a stranger affects the heart rate of the children when interacting with those strangers. Additionally, in the light of earlier evidence that has shown a moderating effect on the influence of verbal threat information on physiological changes, the role of child trait social anxiety has been explored as a possible moderator. A sample of 38 10-to-14-year-old children and their primary caregivers have participated in the current study. Parents gave their child verbal threat or safety information about two strangers that the child had to interact with during social tasks: social performance, watching back their performance, and social interaction. Heart rate was continuously recorded during these social tasks. Child trait social anxiety was measured through the child's report on the social anxiety subscale of the SCARED questionnaire. Results showed that parental verbal expressions of threat versus safety did not have a significant effect on the heart rate of the child. Furthermore, no significant moderation of this effect by child trait social anxiety was found. Conclusively, the results of the current experimental design are not in line with the expected outcome and, therefore, possible explanations and the need for further research have been highlighted.Show less
