Previous studies have shown that the processing of a stimulus is facilitated when that stimulus is repeated compared to when it appears the first time, and this phenomenon is called repetition priming (RP). One explanation for RP is that initial processing of a stimulus strengthens connections within the visual representation, enabling subsequent processing of the same stimulus to be more efficient. More recently, it has been reported that presenting an object with features that overlap with those in a subsequent stimulus impairs the latter's processing, and this cost is termed antipriming (AP). AP is said to be the natural antithesis of RP, and it manifests when two objects share component features, thereby having overlapping representations. In two experiments, we investigated RP and AP in a picture naming task. Following previous research, we used a 4-phase paradigm, in which RP and AP were measured, respectively, by an increase or a decrease in performance for repeated or novel stimuli in Phase 4 compared with the baseline performance in Phase 2. We used a fully randomized design in Experiment 1, and a pseudo-randomized design in stimulus selection but a randomized design in presentation location in Experiment 2. We found robust RP in both experiments, but neither experiment showed any evidence of AP. Our results indicate that RP and AP do not always manifest within the same experiment, and that the relationship between these two effects may be more complex than previously understood.

图片识别中没有反底漆的重复底漆。

先前的研究表明,与第一次出现时相比,重复刺激会促进处理,这种现象称为重复启动(RP)。RP的一种解释是,对刺激的初始处理会增强视觉表示内的联系,从而使对相同刺激的后续处理更加有效。最近,据报道,呈现具有与随后刺激中的那些特征重叠的特征的物体会损害后者的处理,并且这种成本被称为反底漆(AP)。AP被认为是RP的自然对立面,它在两个对象共享组件特征时表现出来,从而具有重叠的表示形式。在两个实验中,我们调查了图片命名任务中的RP和AP。根据先前的研究,我们使用4相范例,其中与相2的基线表现相比,相4的重复或新颖刺激的表现增加或减少,分别测量了RP和AP。实验1,在刺激选择中采用伪随机设计,而实验2中采用随机设计。在两个实验中我们都发现了鲁棒的RP,但没有一个实验显示出AP的证据。我们的结果表明RP和AP并不总是出现在同一实验中,并且这两种作用之间的关系可能比以前理解的更为复杂。与第2阶段的基线性能相比,第4阶段重复或新颖刺激的性能提高或降低。我们在实验1中使用了完全随机设计,在刺激选择中使用了伪随机设计,但在演示中使用了随机设计在实验2中的位置。我们在两个实验中都发现了可靠的RP,但是两个实验均未显示出任何AP迹象。我们的结果表明,RP和AP并不总是出现在同一实验中,并且这两种作用之间的关系可能比以前理解的更为复杂。与第2阶段的基线性能相比,第4阶段重复或新颖刺激的性能提高或降低。我们在实验1中使用了完全随机设计,在刺激选择中使用了伪随机设计,但在演示中使用了随机设计在实验2中的位置。我们在两个实验中都发现了可靠的RP,但是两个实验均未显示出AP的任何证据。我们的结果表明,RP和AP并不总是出现在同一实验中,并且这两种作用之间的关系可能比以前理解的更为复杂。
