Resumo(s)
Musical training is a continuous process that can enhance motor control, acoustic perception,
and the integration of cognitive function. Neuroimaging studies also indicate that music activates brain
regions related to emotional processing and social cognition, suggesting that music training may
improve emotional and social perception. This study investigates whether formal music training is
associated to enhanced emotion recognition processes in both visual and auditory domains, using
behavioral and neurophysiological measures.
We recruited 72 participants, that were divided into musicians’ group and control group, to
perform tasks involving music perception, cognitive skills, and emotion recognition in facial
expressions, prosodic speech, and non-verbal vocalizations. Implicit emotion recognition tasks were
evaluated using electroencephalography (EEG), with a focus on event-related potentials (ERPs), and
functional connectivity (FCon). Explicit emotion recognition tasks were evaluated focusing on accuracy
and response time (RT).
Implicit emotion recognition results showed that musicians had a quasi-significantly stronger
N100 component in the Fronto-Central region, when presented with emotional prosody, and a longer
peak latency in the P100 component in the Right-Temporal region when presented with non-verbal
vocalizations. FCon analysis revealed lower connectivity in the alpha frequency band between the
Fronto-Central and Right Temporal regions for the musicians’ group, when presented with negative nonverbal vocalizations. Behavioral analysis showed no significant differences in explicit emotion
recognition between groups.
Overall, musicians showed a distinct implicit emotion recognition in Fronto-Central and Right
Temporal regions when presented with auditory stimuli, as evidenced by ERPs, and a lower connectivity
between these two regions in the same conditions. Nevertheless, further research is needed to establish
causality between music training and these effects.
