Methods: This study examined 251 children aged 11 of the 5th grade in one primary school at Hangzhou of China with RCMAS,from which 50 of the highest scores(the high anxious group),and 50 of the lowest scores(the low anxious group)were selected. The experimenter asked them to response to the given situations of teacher’s authoritative behaviors. Results: (1) There are significant differences in children’s responses to teacher’s authoritative behaviors between the high and the low anxious group; the high anxious group is more anxious in responset to teacher’s authority than the low one; (2) There are significant differences in male children between the high and the low anxious group, there is no significant difference in female children between the high and the low anxious group.Among the male children, the low anxious group is more teacher’s authority oriented than the high one. Conclusion: The results indicate that children’s anxious levels are related to their responses to teacher’s authoritative behaviors and there are gender differences.展开更多

Methods CNV, P300 and MMN were recorded from 44 depressive patients using Nicolet Spirit Instrument, and were compared with that of 32 anxiety patients and 28 normal controls（NC）. 21 of depressive patients and 18 of anxiety patients were followed up by 2.5 months with the same evoked potentials. Results 1. Compared with NC, all patients in acute episode showed decreased M1 of CNV amplitude, delayed P3 latency and decreased P3 amplitude of P300, and delayed MMN latency and decreased MMN amplitude ; 2. The follow-up study of evoked potentials revealed that abnormal P3 of P300 and MMN latencies were significant between depressed patients in remission status and NC group but not P3 of P300 and MMN amplitudes, and M1 of CNV and P3 of P300 amplitudes and P3 of P300 and MMN latencies are not significant between anxiety patients in remission and NC group. Conclusion Delayed P3 of P300 and MMN latencies in depression show state and trait markers, while those variations in anxiety correlate with clinical status of anxiety state.展开更多

However, the relationship between mOFC activity and anxiety among the healthy population has not been fully examined. Here, we conducted a resting state functional magnetic resonance imaging （R-fMRI） study with 56 healthy male adults from the Nathan Kline Institute/Rockland Sample （NKI-RS） to examine the relationship between the fractional amplitude of low-frequency fluctuation （fALFF） signals and trait anxiety across the whole brain. A Louvain method for module detection based on graph theory was further employed in the automated functional subdivision to explore subregional correlates of trait anxiety. The results showed that trait anxiety was related to fALFF in the mOFC. Additionally, the resting-state functional connectivity （RSFC） between the right subregions of the mOFC and the precuneus was correlated with trait anxiety. These findings provided evidence about the involvement of the mOFC in anxiety processing among the healthy population.展开更多
