Wearing facial masks became a common practice worldwide during the COVID-19 pandemic. This study investigated (1) whether facial masks that cover adult faces affect 4- to 6-year-old children’s recognition of emotions in those faces and (2) whether the duration of children’s exposure to masks is associated with emotion recognition. We tested children from Switzerland (N = 38) and Brazil (N = 41). Brazil represented longer mask exposure due to a stricter mandate during COVID-19. Children had to choose a face displaying (...) a specific emotion (happy, angry, or sad) when the face wore either no cover, a facial mask, or sunglasses. The longer hours of mask exposure were associated with better emotion recognition. Controlling for the hours of exposure, children were less likely to recognise emotions in partially hideen faces. Moreover, Brazilian children were more accurate in recognising happy faces than Swiss children. Overall, facial masks may negatively impact children’s emotion recognition. However, prolonged exposure appears to buffer the lack of facial cues from the nose and mouth. In conclusion, restricting facial cues due to masks may impair kindergarten children’s emotion recognition in the short run. However, it may facilitate their broader reading of facial emotional cues in the long run. (shrink)

The Mathematics Education and Neurosciences project is an interdisciplinary research program that bridges mathematics education research with neuroscientific research. The bidirectional collaboration will provide greater insight into young children's (aged four to six years) mathematical abilities. Specifically, by combining qualitative ‘design research’ with quantitative ‘experimental research’, we aim to come to a more thorough understanding of prerequisites that are involved in the development of early spatial and number sense. The mathematics education researchers are concerned with kindergartner's spatial structuring ability, while (...) the neuroscientists are studying kindergartner's automatic quantity processing and its effect on mathematical development. The outcomes of these investigations should contribute to practical ways of fostering and supporting young children's mathematical thinking and learning. (shrink)

Psychologists believe grade schoolers' free play in the United States is universally biased toward single-gender groups. In a study of grade schoolers in a children's museum, already-acquainted kindergartners to sixth graders were observed at three exhibits. While boys chose more automobile play and girls more supermarketing, one-quarter of each group played in settings dominated by the other gender. Boys had no group-size preference; girls had a strong preference for small groups. That preference accounts for most of the gender differences (...) found in children's gender sorting in a novel environment. However, the ubiquity of gender segregation in large groups of grade schoolers was disconfirmed for this setting. (shrink)
