Resumen:
BACKGROUND: Research suggests that individuals with
different attachment patterns process social information differently,
especially in terms of facial emotion recognition. However, few studies have
explored social information processes in adolescents. This study examined the
behavioral and ERP correlates of emotional processing in adolescents with
different attachment orientations (insecure attachment group and secure
attachment group; IAG and SAG, respectively). This study also explored the
association of these correlates to individual neuropsychological profiles.
METHODOLOGY/PRINCIPAL FINDINGS: We
used a modified version of the dual valence task (DVT), in which participants
classify stimuli (faces and words) according to emotional valence (positive or
negative). Results showed that the IAG performed significantly worse than SAG
on tests of executive function (EF attention, processing speed, visuospatial abilities
and cognitive flexibility). In the behavioral DVT, the IAG presented lower
performance and accuracy. The IAG also exhibited slower RTs for stimuli with
negative valence. Compared to the SAG, the IAG showed a negative bias for
faces; a larger P1 and attenuated N170 component over the right hemisphere was
observed. A negative bias was also observed in the IAG for word stimuli, which
was demonstrated by comparing the N170 amplitude of the IAG with the valence of
the SAG. Finally, the amplitude of the N170 elicited by the facial stimuli
correlated with EF in both groups (and negative valence with EF in the IAG).
CONCLUSIONS/SIGNIFICANCE: Our
results suggest that individuals with different attachment patterns process key
emotional information and corresponding EF differently. This is evidenced by an
early modulation of ERP components' amplitudes, which are correlated with
behavioral and neuropsychological effects. In brief, attachments patterns
appear to impact multiple domains, such as emotional processing and EFs.
