[...] In Experiment a different group of participants performed the RMET task, as well as a facial emotion discrimination task (odd-emotion-out). In both experiments, participants also performed a facial identity discrimination control task (odd-identity-out). In both experiments, participants also performed a facial identity discrimination control task (odd-identity-out). Results : As in Experiment the correlation between performance on emotional items of RMET and the AF of the right UF was significantly stronger than that between performance and emotional EMRM and the AF of the right EFC (z=1.726, p=0.04).

[...] In other words, it is necessary to remain vigilant because correlation is not causality. It would be necessary to integrate other expressive-motor reactions related to social cognition, for example interpersonal and group social functions (Keltner & Haidt, 1999).

[...] The article allows us to evaluate these mechanisms in operation during emotion processing, i.e. to understand in advance of decision-making the role played by the network of association fibers linking the regions of the anterior frontal and temporal lobes (UF). Limitations of the article : The limits of the research are the impossibility of tests to take into account all the complex factors that concern emotions, nor the precise role played by the right UF in the processing of facial emotions.
