阈上和阈下奖励对有意识和无意识的反应抑制的影响

The Effect of Supraliminal and Subliminal Reward Information on Conscious and Unconscious Response Inhibition

为比较阈上奖励和阈下奖励对有意识和无意识反应抑制的影响,实验1将奖励启动范式与传统的go/no-go任务相结合,探讨阈上和阈下奖励对有意识的反应抑制的影响,发现阈上高奖励和阈下高奖励均能够提高个体的有意识的反应抑制;实验2将奖励启动范式和掩蔽版的go/no-go任务相结合,比较阈上奖励和阈下奖励对有意识的反应抑制和无意识的反应抑制的影响,实验2的结果重复了实验1结果,并且进一步发现阈上高奖励能够提高个体的无意识的反应抑制,而阈下奖励对其并没有影响.研究表明:阈上奖励和阈下奖励对有意识的反应抑制的影响是相同的,而对无意识反应抑制的影响是不同的.

This study systematically investigated whether supraliminally and subliminally perceived reward information could influence consciously and unconsciously triggered execrative functions with two experiments. The results of Experiment 1 showed that participants elicited greater consciously triggered response inhibition for high-value reward, regardless of whether the rewards were consciously perceived. Confirming the results showed by Experiment l, the E sciously triggered response inhibition for hi xp gh eriment 2 indicated that participants elicited greater uncon value reward when rewards were presenlcd supraliminally. However, the facilitated performance was not observed when rewards were presented subliminally. In con- clusion, supraliminal and subliminal reward elicited similar effects on consciously triggered response inhibition and had distinct influence on unconsciously triggered response inhibition
