阈下金钱线索对返回抑制的调节作用

Subliminal Money Cue Modulates the Inhibition of Return Effect

采用线索-靶范式,通过两项实验探讨阈下金钱线索对注意返回抑制的调节作用。实验一通过在线索中引入阈下金钱概念(1元/1分/模糊硬币),要求被试对靶子快速做出探测反应。实验二在此基础上引入外币(1卢布硬币),探析物理特征以及熟悉性差异带来的影响。结果显示,只有1元硬币线索显著地减弱了返回抑制效应,物理特征或熟悉性差异并非阈下金钱线索产生调节作用的充分条件,金钱意义可能是金钱对返回抑制产生影响的关键因素。

The classical cue-target paradigm was used in the two experiments to examine whether inhibition of return（ IOR） effect was modulated by subliminal money cues. In Experiment 1,Participants were asked to make quick and accurate response to target stimuli after subliminal money cues（ 1-yuan /1-fen / vague coin）. In Experiment 2,1 Russian ruble coin was introduced to study the influence of physical characteristics and familiarity. The results showed that subliminal 1-yuan coin compared to other coins significantly reduced the IOR effect. The difference of physical characteristics and familiarity among coins is not the sufficient condition for varied modulation effects of subliminal money cues. The significance of money may be the key factor behind the modulation effect of subliminal money cues on IOR.
