It is argued that constructionist theory provides only a partial account of how secure attachment leads to better social understanding. In addition to cooperative parent-child relations, the more efficient arousal and affect regulation system of secure infants, and developmental moderators of the processes of imitation, may play a part in explaining the association and offer clues as to how effective social understanding is generally acquired.
1. Our preferred term for social understanding has been “mentalisation” (see Morton 1989).
2. As the level of cortical activation increases through mutually interactive norepinephrine alpha 2 and dopamine D1 systems, prefrontal cortical function improves on capacities such as anticipation (shifting of attention), planning/organisation, and working memory. With excessive stimulation, norepinephrine alpha 1 and dopamine D1 inhibitory activity increases; the prefrontal cortex goes “off-line,” and posterior cortical and subcortical functions (e.g., more automatic functions) take over. Increasing levels of norepinephrine and dopamine interact such that above threshold, the balance shifts from prefrontal executive functioning to amygdala-mediated memory encoding and posterior-subcortical automatic responding (fight-flight-freeze).
3. In this sense, of course, the constructivist account skirts circularity but gets round it by the assumption of the gradual emergence of the mentalising capacity.
