“…Still, presumed and measured gender differences frequently result
in separate statistical norms for boys and girls (e.g., Bockmann & Kiese-Himmel, 2006 ; Fenson et al, 2008). The selective relevance of
children’s gender in interaction with socio-economic characteristics, such as
maternal education and parental stress levels, has only recently gained
researchers’ attention (e.g., Barbu et al, 2015; Harewood, Vallotton, & Brophy-Herb, 2016 ; Vallotton et al, 2012 ; Zambrana, Ystrom, & Pons, 2012). Possible interactions of
gender and other factors, such as characteristics of the care environment, are
highly relevant and underresearched.…”
