先前的实验表明，在语义一致的视觉上下文中更容易识别对象。然而，情境带来的好处可以用反应偏差来解释，并且可能无法反映情境对认知感知过程的影响。我们进行了六种选择的强制选择实验来测量语义和感知错误。目标对象短暂出现，周围环绕着四个上下文对象。当上下文由与目标语义相关的对象组成时，可以更准确地识别目标。当上下文呈现先于目标时，大量语义错误就会增加，这表明响应偏差确实占了上下文效应的一部分。尽管如此，在偏差修正后仍然存在显着的促进作用。对象的识别不仅当它嵌入连贯的自然场景中时，而且当它仅靠近其他相关对象时，都会受到上下文的影响。与本文相关的材料可访问 www.psychonon-iic.org/archive。
Previous experiments have shown that objects are recognized more readily in a semantically consistent visual context. However, the benefit from context could be explained by response bias, and may not reflect the influence of context on the perceptual processes of recognition. We conducted a six-alternative forced-choice experiment to measure semantic and perceptual errors. A target object appeared briefly, surrounded by four context objects. The target was more accurately identified when the context consisted of objects semantically related to the target. The large number of semantic errors, which increased when the context presentation preceded the target, showed that response bias did account for a proportion of the context effect. Nevertheless, significant facilitation was still present after a bias correction. Recognition of an object can be affected by context not only when it is embedded in a coherent naturalistic scene, but also when it is simply near other related objects.
