Comparative Study Of Affective And Semantic Priming In Lexical Decision Tasks With Mixed Random Conditions

Purpose: To compare the affective and semantic priming effect by supraliminal andsubliminal presentations in lexical decision tasks with mixed random conditions.Method: Standardized matched experimental materials were used in the present study.College students completed lexical decision tasks in two presentation modes (supraliminal:SOA=250ms; subliminal: SOA=72ms), and statistics and analysis were processed bySPSS17.0.Results: Experiment1showed that in supraliminal presentation condition, SOA=250ms,the main effect of the valence of priming stimuli was significant in reaction time (RT),F(1,38)=7.141, p<0.05. Other main effect or interaction effect were not remarkable (p>0.05).In accuracy rate, the main effect of the valence of priming stimuli was significant, F(1,38)=4.935, p<0.05. The interaction of valence of priming stimuli, gender of priming stimuli andtarget stimuli types was significant, F(1,38)=4.551，p<0.05. Other main effect or interactioneffect were not remarkable (p>0.05). The subsequent simple simple effect analysis showed nostatistical difference (p>0.05). Experiment2showed that in subliminal presentation condition,SOA=72ms, showed no priming effect in RT or accuracy time.Conclusion:(1) In supraliminal presentation priming stimuli condition (Experiment1)，there was no priming effect and semantic priming, This show that in the lexical decision task,subjects do not process priming stimulus at deep level, and priming was weaken by therandom presentation information’s competition.(2) In subliminal presentation priming stimulicondition (Experiment2), no affective or semantic priming effect appeared reflects that thesubjects were do not process priming stimulus at deep level in the lexical decision task, andpriming was weaken by the random presentation information’s competition.In addition, thesubliminal priming effect is an unstable weak phenomenon.(3) In conclusion, this studysuggests that, priming effect is not triggered by lexical decision task easily and priming effectwas weakened by the random presentation information’s competition.
