Several studies showed a positive effect of stories on Theory of Mind (ToM) performance. The aim of the present exploratory study was to investigate whether and how a specific aspect of narrative, i.e., character perspective, modulates the brain activation in response to a ToM task and improve the accuracy. Fifty participants were divided in three groups based on the text assigned: first-person perspective group (1 G; n = 16), third-person perspective group (3 G; n = 18) and a scientific essay group (EG; n = 16). The electroencephalographic and behavioral responses to eyes expressions, taken from the "Reading the Mind in the Eyes" test, were recorded pre-(T0) and post-(T1) reading task. The main results showed a greater N100 on left fronto-central electrodes and a greater P220-400 on right temporo-parietal electrodes in response to eye expressions at T1 compared to T0 in 3 G. A lower N220-400 was found on right fronto-central in response to eye expressions at T1 compared to T0 in 1 G and 3 G. The results suggest that, although reading first- and third-person stories modulates self-processes in a similar way, third-person stories involve an early stage of processing and a more extended neural network including anterior-posterior brain sites.
