Sociologists study the impact religion has on child development -- ScienceDailyThey found that third-graders' psychological adjustment and social competence were positively correlated with various religious factors. However, students' performance on reading, math, and science tests were negatively associated with several forms of parental religiosity. The findings suggest that parental religiosity is a mixed blessing that produces significant gains in social psychological development among third-graders while potentially undermining academic performance, particularly in math and science. "Religion emphasizes moral codes designed to instill values such as self-control and social competence," said Bartkowski. "Religious groups' prioritization of these soft skills may come at the expense of academic performance, which is generally diminished for youngsters raised in religious homes when compared with their non-religious peers."
