Neurophysiological markers associated with heterogeneity in conduct problems, callous unemotional traits, and anxiety
2018 — Neurophysiological heterogeneity across children and young adults
Question
Do CP/CU/anxiety subgroups show distinguishable physiological profiles, and do those patterns differ across developmental samples?
Finding
Primary, secondary, anxious, and low-risk groups differed in autonomic/startle responses; young-adult groups also differed in medial prefrontal response. The pattern was not reducible to one 'low arousal' marker.
Why it matters
This is a convergence node: subgroup theory, psychophysiology, and developmental comparison are tested in the same architecture.
Inference boundary
The samples are cross-sectional age groups, not a longitudinal demonstration that the same physiological pathway persists within individuals from childhood into adulthood.
