【摘要】 采用2(材料)×3(戒毒阶段)两因素混合实验设计,运用EyelinkⅡ眼动仪,考察不同阶段36名戒毒人员观看毒品图与非毒品图的眼动特点,结果发现:(1)被试观看毒品图与非毒品图的眼动指标存在显著的阶段差异:被试观看毒品图的注视时间,第一阶段显著长于第二、三阶段,第二阶段显著长于第三阶段;注视次数,第一阶段显著多于第二、三阶段,第二阶段显著多于第三阶段;眼跳次数及回视次数,第一阶段显著多于第二、三阶段,第二、三阶段间不存在显著差异;三个阶段被试观看非毒品图的各项眼动指标的差异不显著。(2)被试观看毒品图与非毒品图的眼动指标存在显著的材料差异:第一阶段被试观看毒品图的注视时间显著长于非毒品图,注视次数、眼跳次数、回视次数显著多于非毒品图;第二阶段被试对毒品图的注视时间显著长于非毒品图,注视次数、回视次数之间不存在显著差异;第三阶段被试观看毒品图与非毒品图的各项眼动指标之间均不存在显著的差异。更多还原

【Abstract】 By adopting the experiment method of eye movements through EyelinkⅡeye tracker,the research employs the "2(materials)x3(periods)" model and 36 addicts in different treatment periods to record and analyze the eye movements index when watching drug pictures and non-drug pictures.The results are as follows.(1) When the subjects are watching drug pictures or non-drug ones,there is significant difference of the index of eye movements in different periods.The fixation time in PeriodⅠis significantly longer than that in PeriodⅡandⅢ,and PeriodⅡsignificantly longer than PeriodⅢ.The frequency of fixation in PeriodⅠis much more than that in PeriodⅡandⅢ,and PeriodⅡmore than PeriodⅢ.The frequencies of eyelid,and regression in PeriodⅠare significantly higher than that in PeriodⅡandⅢ,but there is no significant difference in PeriodⅡandⅢ.No significant difference of every index of eye movements is found among the three periods.(2) When the subjects are watching drug pictures or non-drug pictures,there is significant difference of the index of eye movements in different materials.In Period I,fixation time on drug pictures is significandy longer than that on non-drug ones and frequencies of fixation,eyelid,and regression are significantly longer than those on non-drug pictures.In PeriodⅡ,the fixation time on drug pictures is significantly longer than that on non-drug ones,but there’s no significant difference of fixation frequency and regression frequency between drug pictures and non-drug ones. In Period in,no significant difference of the index of eye movements is found between drug pictures and non-drug ones.更多还原
