特质正念对医学生注意偏向的影响研究

A Study on the effect of trait mindfulness on attention bias of medical students

目的:考察不同特质正念水平的医学生在对不同情绪面孔图片的注意偏向。方法:采用正念注意觉知量表(MAAS),筛选出高、低特质正念组被试各30名。实验采用2(特质正念水平:高、低)×3(图片属性:积极、中性、消极)的两因素混合实验设计对60名医学生进行选择性注意实验。结果:特质正念水平、刺激类型的主效应显著,刺激类型和组别之间的交互效应显著F(2,112),P<0.01,η2=0.491。在积极情绪图片上,高特质正念组反应时显著快于低特质正念组,F=49.52,P<0.01;在消极情绪图片上,高特质正念反应时显著长于低特质正念,F=58.61,P<0.01。结论:高特质正念个体对积极刺激更为敏感,而低特质正念水平个体对消极刺激反应更为敏感。

Objective:To investigate the attention bias of medical students with high and low trait mindfulness toward pictures of different emotional stimuli.Methods:30 participants in the high and low trait mindfulness group were selected by the mindfulness attention awareness scale(MAAS).The experiment adopted a two-factor mixed experiment design of 2(trait mindfulness level:high,low)×3(image attribute:positive,neutral,negative)to conduct selective attention experiment on 60 medical students.Results:The main effect of trait mindfulness level,the type of stimulates were significant,and the interaction between trait mindfulness and stimulation were significant,F(2,112),P<0.01,η2=0.491.To positive stimuli,the reaction time of the hightrait mindfulness group was significantly faster than that of the low trait mindfulness group(F=49.52,P<0.01).To the negative emotional pictures,the reaction time of high trait mindfulness was significantly longer than the low trait mindfulness(F=58.61,P<0.01).Conclusions:Individuals with high trait mindfulness are more sensitive to positive stimuli,while individuals with low trait mindfulness are more sensitive to negative stimuli.
