چکیده انگلیسی
The ability of humans to predict and explain other people's actions is of immense value for adaptive behavior and nonverbal communication. Gender differences are often evident in the comprehension of social signals, but the underlying neurobiological basis for these differences is unclear. Combining visual psychophysics with an analysis of neuromagnetic activity, we assessed gender effects on the induced oscillatory response to visual social interaction revealed by motion. A robust difference in the induced gamma response was found between females and males over the left prefrontal cortex, a region implicated in perceptual decision making. The induced gamma neuromagnetic response peaked earlier in females than in males. Moreover, it appears that females anticipate social interaction predicting others' actions ahead of their realization, whereas males require accumulation of more sensory evidence for proper social decisions. The findings reflect gender-dependent modes in cortical processing of visually acquired social information. Contrary to popular wisdom, the outcome of this study indicates that gender effects are not evident in the neural circuitry underpinning visual social perception, but in the regions engaged in perceptual decision making.
