Objective To study the attentional deployment strategy of emotion regulation and its processing mechanisms in alexithymia.Methods 21 alexithymia subjects and 22 normal subjects completed attentional deployment task.The reaction time(RT) and accuracy were recorded automatically and the event-related potentials (ERPs) were recorded by neuroscan system.Results ①From the behavioral results,the differences of RT and accuracy to neutral pictures ((1840.17±204.44) ms vs (1845.17±252.97) ms;(0.859±0.073) vs (0.884±0.068)) and negative pictures ((1888.94±200.09) ms vs(1890.38±263.72) ms);(0.845±0.088) vs (0.845±0.091)) in calculation task between two groups were not statistically significant(all P＞0.05).The differences of RT and accuracy in emotion task were not statistically significant(P＞0.05).②In RT and accuracy,the task main effects were statistically significant(F(1,42) =637.40,P＜0.01;F(1,42)=15.00,P＜0.01),the emotion main effects were statistically significant (F(1,42)=30.23,P＜0.001;F(i,42)=47.87,P＜0.01),the interaction effects of task and emotion were statistically significant(F(2,41) =5.20,P＜0.05;F(2,41)=6.01,P＜0.05).③The differences between two groups in P3 amplitude induced by neutral pictures and negative pictures in calculation task were not statistically significant(P＞0.05).P3 amplitude induced by negative pictures were siguificantly greater than those induced by neutral pictures in emotion task((-0.138±0.463) μV vs (0.789±0.541) μV).Conclusion The attentional deployment can effectively regulate the negative pictures processing and occur in the late stage of the picture processing.No attentional deployment defects in alexithymia.

Objective To investigate the capability of empathy for pain in migraineurs without aura.Methods Thirty migraineurs without aura and thirty matched healthy controls were recruited.Picturecued Empathy for pain paradigm was used to compare the capability of empathy in the migraine group with that in the control group.Results Compared with the control group,the migraine group had diminished ability to discriminate painful from nonpainful pictures,and the discrimination accuracy was significantly reduced ((2.55±0.61) vs (2.88±0.38);t=-2.505,P=0.01).In the task laterality,there was no difference in discrimination accuracy between two groups(P＞0.05).The rating scores of patients were evidently smaller than those of control group ((3.01±0.52) vs (3.37±0.47);t=-2.827,P=0.006).Pearson correlation analysis showed that the age of migraineurs was negatively correlated with the discrimination accuracy(r=-0.393,P =0.031),and there was no correlation between migraineurs' educational years,disease course,severity,Mini-mental State Examination,Hamilton Anxiety Scale,Hamilton Depression Scale,Verbal Fluency Test,Stroop Test and the idex of empathy for pain (all P＞0.05).Conclusion Migraineurs without aura have deficiency in the capability of empathy for pain.

Objective To investigate the capability of empathy for pain in bipolar disorder (BD). Methods Thirty-two patients with BD (16, 8 and 8 in depressed, manic and remitted phases, respectively) and 32 healthy controls matched for age, gender and education were recruited. Empathy for pain paradigm were used. Subjects were required to judge whether the person in the picture felt painful and rate pain degree regarding to painful and neutral pictures. Accuracy, reaction time and ratings of pain degree were used as indicators of empathy for pain. Chinese version of Interpersonal Reactivity Index (IRI-C) were used to measure empathy. Results Compared to controls, accuracy of painful pictures was significantly lower in patients [(0.74±0.16) vs.(0.83±0.10), P<0.05]. Reaction time for both painful [(903.84±167.49) ms vs. (765.06±108.21) ms] and neutral [(880.44 ± 190.36) ms vs. (750.31 ± 103.15)ms] pictures were significantly longer in patients (P<0.05). Pa?tients showed lower scores in factors of perspective taking [(9.20±5.43) vs. (12.43±4.13)], fantasy [(11.85±4.57) vs. (15.50± 5.56)] and empathy concern [(14.59±5.35) vs. (17.63±3.37)] in IRI-C (P<0.05). Accuracy of painful pictures was positively correlated with scores in fantasy (r=0.37, P=0.04) and reaction time was positively correlated with duration of disease in pa?tients (r=0.64, P<0.01). Conclusion Bipolar disorder has deficit in the capability of empathy for pain.
