当对视觉目标的身份做出反应时，与目标相同的反应相关联的附近刺激（侧翼）比与不同反应相关联的侧翼引起更快和更准确的反应。由于这种侧翼一致性效应（FCE）随着目标-侧翼分离的增加而降低，因此被认为反映了空间选择机制的有限精度。然而，后来的研究表明，当目标和侧翼是相同颜色时，FCE比当它们是不同颜色时更大。这导致了群体选择假说，即侧翼个体在感知上与目标群体在一起，并被强制性地沿着选择，而不管空间距离如何。另一种假设，图像分割假设，指出，功能差异促进分割的视觉信息成相关和不相关的部分，从而减轻了空间精度的选择机制的限制。我们测试这些假设之间使用的设计，其中目标和侧翼分组或不分组，而保持功能的差异，在刺激恒定。与早期的结果相反，我们发现，当特征差异保持不变时，相同颜色的侧翼不会产生比不同颜色的侧翼更大的FCE。我们的结论是，相似性效应的FCE反映了不同的支持图像分割，选择之前，而不是强制性的选择的感知分组侧翼和目标。
When responding to the identity of a visual target, nearby stimuli (flankers) that are associated with the same response as the target cause faster and more accurate responding than flankers that are associated with different responses. Because this flanker-congruence effect (FCE) decreases with increasing target-flanker separation, it was thought to reflect limited precision of spatial selection mechanisms. Later studies, however, showed that FCEs are larger when the target and flankers are the same color compared to when they are different colors. This led to the group selection hypothesis, which states that flankers are perceptually grouped with the target and are obligatorily selected along with it, regardless of spatial separation. An alternative hypothesis, the image segmentation hypothesis, states that feature differences facilitate the segmentation of visual information into relevant and irrelevant parts, thereby mitigating the limitations of spatial precision of selection mechanisms. We test between these hypotheses using a design in which targets and flankers are grouped or not grouped, while holding feature differences in the stimulus constant. Contrary to earlier results, we found that same-colored flankers do not yield larger FCEs than different-colored flankers when feature differences are held constant. We conclude that similarity effects on the FCE reflect differential support for image segmentation, prior to selection, rather than the obligatory selection of perceptually grouped flankers and targets.
