Boyce and Ellis (2005) contend that heightened responsivity may reflect, not simply exaggerated arousal under challenge, but rather a form of enhanced, neurobiologically-mediated sensitivity to context, or biological sensitivity to context (BSC). children showing low cardiovascular or immune reactivity to stressors had approximately equal rates of respiratory illnesses in both low and high adversity settings. Second, and consistent with the prevailing diathesis-stress model, highly biologically responsive children exposed to high adversity child care settings or home environments had substantially higher illness incidences than all other groups of children. The third, and unexpected, finding was that highly responsive children living in lower adversity conditions – i.e., more supportive child care or family settings – had the lowest illness rates, significantly lower than even low responsive children in comparable settings. ~ Boyce et al (1995b)
