Developmental changes in neural correlates of cognitive reappraisal: An ERP study using the late positive potential

摘要

Objective: The reduction of the amplitude of the late positive potential (LPP) following cognitive reappraisal has been used as a neural marker of emotion regulation. However, studies employing this neural marker in children are scarce and findings are not conclusive, with most studies showing a lack of LPP modulation after reappraisal in children in the age range of 5-12 years. The aim of the current study was therefore to investigate developmental changes in sensitivity of LPP modulation to cognitive reappraisal. To do so, LPP modulation due to cognitive reappraisal of negative pictures was compared between two age groups (8- to 11- versus 12- to 15-year-olds) and regression analyses were applied within the total sample to test whether sensitivity of LPP modulation shows a linear increase with age.
