ABSTRACT
Objective To study the mechanism underlying attentional biases toward event-related potentials (ERPs) in healthy male subjects.Methods 18 male healthy subjects performed emotional stroop task by pressing the buttons to the picture border color of two categories including the neutral and positive.The RT and Accuracy were recorded automatically.The ERPs were recorded by Neuroscan system.Results The behavioral results showed that neither the reaction time (628.11 ± 55.46) ms vs (628.81 ± 53.92) ms nor accuracy (96.87 ± 4.42) % vs (95.76±7.41)% found difference under two conditions.ERPs results showed that the positive pictures evoked more greater P2 ((8.16±4.99)μV vs (4.30±3.83)μV) and P3 ((6.31±4.53)μV vs (4.27±4.16)μV) than neutral pictures.Conclusion Attentional biases toward positive emotion can be found in healthy male subjects,which can be related to emotional control process.
