Deficits in development

Callous-unemotional traits have been linked to deficits in development of the conscience and of empathy. (…) The findings show that in typically-developing boys, the volume of the anterior insula – a brain region implicated in recognizing emotions in others and empathy – is larger in those with higher levels of callous-unemotional traits. This variation in brain structure was only seen in boys, but not in girls. (…) Callous-unemotional traits are related to differences in brain structure in typically-developing boys without a clinical diagnosis.
