Abstract

Previous research suggests that selective spatial attention is a determining factor for unconscious processing under continuous flash suppression (CFS), and specifically, that inattention toward stimulus location facilitates its unconscious processing by reducing the depth of CFS (Eo et al., 2016). The aim of our study was to further examine this modulation-by-attention model of CFS using a number priming paradigm. Participants (N = 26) performed a number comparison task on a visible target number ("compare target to five"). Prime-target pairs were either congruent (both smaller or larger than five) or incongruent. Spatial attention toward the primes was varied by manipulating the uncertainty of the primes' location. Based on the modulation-by-attention model, we hypothesized the following: In trials with uncertain prime location, RTs for congruent prime-target pairs should be faster than for incongruent ones. In trials with certain prime location, RTs for congruent versus incongruent prime-target pairs should not differ. We analyzed our data with sequential Bayes factors (BFs). Our data showed no effect of location uncertainty on unconscious priming under CFS (BF0+ = 5.16). However, even visible primes only weakly influenced RTs. Possible reasons for the absence of robust number priming effects in our study are discussed. Based on exploratory analyses, we conclude that the numerical order of prime and target resulted in a response conflict and interfered with the predicted priming effect.

在连续闪光抑制下,位置不确定性是否会调节无意识加工?
已有研究表明,选择性空间注意是连续闪光抑制(continuous flash suppression, CFS)下无意识加工的决定因素,特别是对刺激位置的不注意通过降低CFS深度来促进其无意识加工(Eo et al., 2016)。本研究的目的是使用数字启动范式进一步检验CFS的注意调节模型。参与者(N = 26)在一个可见的目标数字上执行数字比较任务(“将目标与5进行比较”)。启动目标对要么是一致的(小于或大于5),要么是不一致的。对质数的空间注意通过操纵质数位置的不确定性而发生变化。基于注意调节模型,我们假设:在启动位置不确定的试验中,一致启动-目标对的rt反应速度比不一致启动-目标对的rt反应速度快。在具有特定启动定位的试验中,一致与不一致启动-目标对的RTs不应存在差异。我们用顺序贝叶斯因子(BFs)分析我们的数据。我们的数据显示,位置不确定性对CFS下无意识启动没有影响(BF0+ = 5.16)。然而,即使是可见的质数对RTs的影响也很弱。讨论了在我们的研究中缺乏稳健的数字启动效应的可能原因。在探索性分析的基础上,我们发现启动数和目标数的顺序会导致反应冲突,从而影响预测的启动效应。
