ObjectiveAlthough it has
been shown that adults with ADHD have impaired social cognition, no previous
study has reported the brain correlates of adult ADHD for face valence
processing. This study looked for behavioral, neuropsychological and
electrophysiological markers of emotion processing for faces (N170) in adult
ADHD (13) compared to controls (13) matched by age, gender, educational level
and handedness.
MethodWe designed an
event related potential (ERP) study based on a Dual Valence Task (DVT), in
which faces and words were presented to test the effects of stimulus type
(faces, words or face-word stimuli) valence (positive vs. negative) and
compatibility (compatible vs. incompatible word and face valence combinations).
In order to identify individual signatures of cognitive functioning in
participants with ADHD and controls, a comprehensive neuropsychological
assessment was carried out, which included measures of executive functioning
(EF) and theory of mind (ToM).
ResultsCompared to
controls, the adult ADHD group showed deficits in N170 emotion discrimination
for facial stimuli. These N170 impairments were observed in absence of any
deficit in facial structural processing, suggesting a specific ADHD impairment
in early facial emotion discrimination. In participants with ADHD, N170 emotion
processing was associated with performance on an emotional inference ToM task,
and N170 from simultaneous stimuli was associated with EF, especially working
memory.
