In this study, we ask whether consensus testimony affects children’s judgments of the possibility of improbable and impossible events. Fifty-six U.S. and Chinese 8-year-olds made possibility judgments before and after hearing three speakers affirm or deny the possibility of improbable and impossible events. Results indicated that whereas both U.S. and Chinese children altered their judgments in the direction of the consensus testimony, this effect was stronger for Chinese children. U.S. children were particularly receptive to consensus for improbable events and when (...) the consensus provided correct information, whereas Chinese children were similarly willing to change their judgment regardless of event type and the validity of the testimony. We propose that the extent of the influence of testimony on possibility judgments varies based on cultural setting. Our findings have potential applications for domains that require evaluation of counterintuitive claims, like religious and scientific education. (shrink)

Three experiments were conducted to test whether watching an animated show with frequent fantastical events decreased Chinese preschoolers’ post-viewing executive function, and to test possible mechanisms of this effect. In all three experiments, children were randomly assigned to watch a video with either frequent or infrequent fantastical events; their EF was immediately assessed after viewing, using behavioral measures of working memory, sustained attention, and cognitive flexibility. Parents completed a questionnaire to assess preschoolers’ hyperactivity level as a potential confounding variable. In (...) Experiment 1, which also included a control group, there was an immediate negative effect of watching frequent fantastical events, as seen in lower scores on the behavioral EF tasks. In Experiment 2, eye tracking data showed more but shorter eye fixations in the high frequency group, suggesting a higher demand on cognitive resources; this group also did more poorly on behavioral measures of EF. In Experiment 3, functional near-infrared spectroscopy data showed that the high frequency group had a higher concentration of oxygenated hemoglobin, an indicator of higher brain activation consistent with a greater use of cognitive resources; this group also had lower scores on the behavioral EF tasks. The findings are discussed in reference to models of limited cognitive resources. (shrink)
