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.
ABSTRACT
ObjectiveTo explore the psychological training methods on improving the mental adaptation and performance of recruits.MethodsAccording to army's squad establishment,372 recruits were randomly extracted and divided into intervention group (182) and control group (190).A series of special group psychological trainings,such as Warm barracks,Friendly Care,Self-awareness,Interpersonal communication,etc,was applied to the recruits of the intervention group through the squad leaders given psychological training.The effect was assessed with Psychosocial Stress Survey For Groups (PSSG),General Maladjustment Scale (GM),Social Support Rating Scale (SSRS),General Self-Efficacy Scale (GSES),Wallace Slef-Concept Scale (WSCS) and Examined Performance.ResultsThe scores of negative emotion was [(3.89±2.01) score vs (2.56±1.65) score ],negative copy was [(3.96±2.52) score vs (2.97±1.78)score],total stress was [(46.36±21.74)score vs (33.71±17.56) score],maladjustment was [(11.26±5.04)score vs (9.10±4.53)score] in the intervention group,which was significantly reduced than those in the control group(P＜0.01).But the scores of positive emotion was [(3.70±1.62) score vs (4.16±1.84) score],positive copy was [(5.21±1.94) score vs (6.93±2.17) score ],subjective support was [(21.37±3.59)score vs (22.56±3.53)score] and support utilization was [(7.03±2.16) score vs (8.92±2.44) score],self-concept was [(74.33±15.72) score vs (80.65±13.98) score],self-efficacy was [(2.44±0.56) score vs (2.91.±0.52) score ] and the examination performance was [(pull-up:(5.12±3.77) times vs (12.09±4.52) times; sit-up:(30.82±9.54) times/3 min vs (70.20±16.83) times/3min; push-up:(21.32±9.73)times/2 min vs (61.75±17.62)times/2 min; Running 3000 meters:(14.17±1.14) s vs (12.82±0.32) s; standing grade throw:(26.68±4.62) mvs (35.38±8.44) m ],which was significantly improved (P＜0.01 or P＜0.05).ConclusionsComprehensive group psychological training implemented by Squad leader could effectively improve the ability of adaptation of recruits and promote the performance.
