在搜索目标的过程中,我们的视觉系统不仅优先考虑目标相关的功能,但也可以抑制非目标相关的功能。虽然这个模板的拒绝已经得到了很好的证明,无论是功能(即对象)或位置的抑制仍然没有得到解决,由于在以前的研究中的实验范式:特别是,基于对象的模板的拒绝混淆与基于位置的抑制视觉搜索范式。本研究探讨了一个基于对象的模板,通过引入搜索阵列,包括两个重叠的形状与搜索项目分布沿着形状的轮廓拒绝。为了阻止基于位置的抑制,这两个形状在空间上混合(实验1),旋转(实验2),或抖动(实验3)。参与者识别目标十字架的颜色。前线索指示目标将出现的形状(正线索条件)、仅干扰物将出现的形状(负线索条件)或与当前搜索阵列无关的形状(中性线索条件)。在所有三个实验中,反应时间的负面线索条件比那些中性线索条件,这是一个基于对象的模板拒绝效果的标志,即使在基于位置的抑制被劝阻的条件下,短。
In the process of searching for targets, our visual system not only prioritizes target-relevant features, but can also suppress nontarget-related features. Although this template for rejection has been well demonstrated, whether the features (i.e. the objects) or locations are suppressed remains unresolved due to the experimental paradigms in previous studies: in particular, object-based templates for rejection were confounded with location-based inhibition in visual search paradigms. The present study examined an object-based template for rejection by introducing search arrays comprised of two overlapping shapes with search items distributed along the shape's contours. To discourage location-based inhibition, the two shapes were spatially intermingled (Experiment 1), rotated (Experiment 2), or jiggled (Experiment 3). Participants identified the colour of a target cross. The pre-cue indicated the shape in which the target would appear (positive cue condition), the shape in which only distractors would appear (negative cue condition), or the shape that was irrelevant to the current search array (neutral cue condition). In all three experiments, the reaction times for the negative cue condition were shorter than those for the neutral cue condition, which is a hallmark of the object-based template for rejection effect, even under conditions in which location-based inhibition was discouraged.
