A child witness’s testimony may be an invaluable piece of evidence; therefore, it is essential to study the circumstances under which jurors perceive children as credible witnesses. The current study examined affect while testifying on perceptions of the child’s credibility, the amount of blame attributed to the witness, and case verdict decisions. A case scenario about an aggravated robbery of a girl who was either 6- or 13-years-old and who either cried or remained calm while testifying was read by 186 undergraduate participants. No age effects were found, possibly due to the non-sexual nature of the case. No effects for expression of affect were found, possibly because participants need to view affective reactions for them to be influential.
