"According to German psychiatrists, the eyes are truly a window to a woman's soul. 'They remain one of the richest sources of social information for the attribution of mental states to others,' says Boris Schiffer, a researcher at LWL-University Hospital in Bochum.
But men are only half as good as women at interpreting a woman's emotions by looking into her eyes, according to Dr Schiffer. His research suggests that women show increased activity in areas of the brain that regulate emotion and memory - the limbic regions -when looking into another woman's eyes. Men's brains generally show less activity here."
"The finding of heightened right amygdala responses during recognition of male compared to female stimuli might indicate a highly automated and stimulus-driven effect that occurred regardless of different conditions or instructions. Thus, increased right amygdala responses to male stimuli may indicate a sex-specific association between stimulus type (male vs. female) and automated emotion processing or affective empathy. The positive correlation between right amygdala responses and the ability to infer mental states from male but not female eyes also indicated that affective empathy might enhance mentalizing performance for male stimuli in men. Conversely, this indicated that the processing of opposite-sex stimuli might be associated with lower affective empathy which may also be associated with a reduced mentalizing ability. In support of this assumption, a previous study investigating emotion recognition accuracy in two patients with acquired amygdala lesions showed impaired emotion recognition using an earlier version of the RMET . Results from this study particularly showed impairment in the male patient with right amygdala damage, whereas the female patient with bilateral amygdala lesion did not present any mentalizing impairments. Notably, both patients made comparable numbers of errors on items on the RMET ."
