Resumen:
Several lines of experimental evidence support an association between
facial processing and social cognition, but no direct link between
cortical markers of facial processing and complex cognitive processes
has been reported until now. In the current study, we tested the
hypothesis that cortical electrophysiological markers for the processing
of facial emotion are associated with individual differences in
executive and social cognition skills. We tested for correlations
between the amplitude of event-related potentials (N170) in a dual
valence task and participants' scores on three neuropsychological
assessments (general neuropsychology, executive functioning, and social
cognition). N170 was modulated by the stimulus type (face versus word)
and the valence of faces (positive versus negative). The neural source
of N170 was estimated to be the fusiform gyrus. Robust correlations were
found between neuropsychological markers and measures of facial
processing. Social cognition skills (as measured by three tests: the
Reading the Mind in the Eyes test, the Faux Pas test, and the Iowa
Gambling Task) correlated with cortical measures of emotional
discrimination. Executive functioning ability also correlated with the
cortical discrimination of complex emotional stimuli. Our findings
suggest that the cortical processing of facial emotional expression is
associated with social cognition skills.
