Introspective self-narrative modulates the neuronal response during the emphatic process: an event-related potentials...

Area of Science:

• Cognitive Neuroscience
• Social Psychology
• Affective Neuroscience

Background:

• Empathy, the capacity to understand and share others' emotions, is crucial for social interaction.
• Prior research indicates self-reflection can augment empathic abilities.
• Event-related potentials (ERPs) offer insights into the temporal dynamics of cognitive processes.

Purpose of the Study:

• To investigate if self-reflection, induced by introspective writing, alters neural responses to eye expressions.
• To determine if self-reflection enhances the accuracy of empathic processing.
• To examine the impact of an introspective self-narrative task on electroencephalographic (EEG) and behavioral data.

Main Methods:

• Twenty-nine participants were assigned to either an introspection group (IG) or a control group (CG).
• The IG completed a 7-day introspective writing task, while the CG performed a non-introspective writing task.
• EEG and behavioral responses to eye-expression images from the 'Reading the Mind in the Eyes' test were recorded before (T0) and after (T1) the intervention.

Main Results:

• The introspection group (IG) exhibited a significant change in P300 amplitude in response to eye expressions at T1 compared to T0.
• This modulation in P300 amplitude was observed specifically at the left centro-frontal electrode montage.
• No significant improvements in empathic accuracy were detected between T0 and T1 for either group.

Conclusions:

• Introspective writing appears to modulate neural attention and implicit evaluation of socio-emotional stimuli, as indicated by ERP changes.
• The findings suggest that neuronal modulation may be linked to heightened embodied simulation processes involved in affective empathy.
• While neural responses changed, the study did not find evidence that this specific introspective task improved explicit empathic accuracy.
