The negative impact of adverse experiences in childhood on neurodevelopment is well documented. Less attention however has been given to the impact of variations in “normative” parenting behaviors. The influence of these parenting behaviors is likely to be marked during periods of rapid brain reorganization, such as late childhood. The aim of the current study was to investigate associations between normative parenting behaviors and the development of structural brain networks across late childhood. Data were collected from a longitudinal sample of (...) 114 mother-child dyads, recruited from low socioeconomic areas of Melbourne, Australia. At the first assessment parenting behaviors were coded from two lab-based interaction tasks and structural magnetic resonance imaging scans of the children were performed. At the second assessment, approximately 18 months later MRI scans were repeated. Cortical thickness was extracted from T1-weighted images using FreeSurfer. Structural covariance networks were constructed from partial correlations of CT estimates between brain regions and estimates of network efficiency and modularity were obtained for each time point. The change in these network measures, from Time 1 to Time 2, was also calculated. At Time 2, less positive maternal affective behavior was associated with higher modularity, while negative maternal affective behavior was not related. No support was found for an association between local or global efficacy and maternal affective behaviors at Time 2. Similarly, no support was demonstrated for associations between maternal affective behaviors and change in network efficiency and modularity, from Time 1 to Time 2. These results indicate that normative variations in parenting may influence the development of structural brain networks in late childhood and extend current knowledge about environmental influences on structural connectivity in a developmental context.

This article builds on the recent Special Interest issue of this journal on ‘Philosophy for Children in Transition’ and the way that the debate about philosophy in schools has now shifted to whether or not it ought to be a compulsory part of the curriculum. This article puts the spotlight on Catholic schools in order to present a different argument in favour of introducing compulsory philosophy lessons into the curriculum. It is explained that in faith schools, such as Catholic ones, (...) there is an additional need or imperative to have compulsory philosophy as part of the curriculum. This is because it serves as an effective way of avoiding the inherent dangers of confessional education, particularly the indoctrination challenge. It is argued that Catholic schools also have some intriguing theological reasons that can be used to justify the inclusion of compulsory philosophy in the school curriculum. It is proposed that when it comes to philosophy in schools there is a distinctive Catholic school perspective. As part of this it is explained why Catholic schools, perhaps more than others, need philosophy to be a compulsory part of the curriculum. (shrink)
