Children show increasing control of emotions and behavior during their early years. Our studies suggest a shift in control from the brain’s orienting network in infancy to the executive network by the age of 3—4 years. Our longitudinal study indicates that orienting influences both positive and negative affect, as measured by parent report in infancy. At 3—4 years of age, the dominant control of affect rests in a frontal brain network that involves the anterior cingulate gyrus. Connectivity of brain structures (...) also changes from infancy to toddlerhood. Early connectivity of parietal and frontal areas is important in orienting; later connectivity involves midfrontal and anterior cingulate areas related to executive attention and self-regulation.

In recent years the historical relationship between scientific experts and the state has received increasing scrutiny. Such experts played important roles in the creation and regulation of environmental organizations and functioned as agents dispatched by politicians or bureaucrats to assess health-related problems and concerns raised by the public or the judiciary. But when it came to making public policy, scientists played another role that has received less attention. In addition to acting as advisers and assessors, some scientists were democratically elected (...) members of local and national legislatures. In this essay I draw attention to this phenomenon by examining how liberal politicians and intellectuals used Darwinian cognitive science to conceptualize the education of children in Victorian Britain.
