This article examines the effect that prior exposure to perceptual stimuli has on the prevalence of overall similarity (family resemblance) categorization. Experiment 1 demonstrated that participants who had previously encountered stimuli produced more overall similarity sorting when asked to free classify them than participants who were preexposed to different stimuli to those they later classified. Experiments 2a and 2b showed that this effect is modulated by the perceptual difficulty of the stimuli-preexposure statistically increased overall similarity sorting for perceptually easy stimuli but not for perceptually difficult stimuli. Overall similarity sorting was also significantly higher for perceptually easy stimuli than for perceptually difficult stimuli. Experiment 2b additionally showed that preexposure increased the discriminability of the perceptually easy stimuli but this effect was not statistically detectable for perceptually difficult stimuli. Experiment 3 established that the preexposure effect is also influenced by the spatial separateness of the stimulus dimensions-preexposure significantly elevated overall similarity sorting when the dimensions were integrated into a coherent object but not when they were spatially separated. Similarly, there was a statistically significant increase in the perceptual discriminability of the spatially integrated stimuli after preexposure but not for the spatially separate stimuli. Taken together, these results demonstrate that preexposure can elevate overall similarity sorting and provide insight into the conditions under which the effect will occur.

预曝光对整体相似性分类的影响。

本文研究了事先接触知觉刺激对总体相似性（家族相似性）分类的普遍性的影响。实验1证明，与以前受到刺激的参与者相比，那些曾经受到刺激的参与者对他们进行自由分类时，被要求对他们进行自由分类时，他们产生的整体相似度更高。实验2a和2b表明，这种效果受刺激-预暴露的感知困难的调节，对于易感觉的刺激，统计上增加的总体相似性排序对感觉上容易的刺激而不是对感觉上困难的刺激进行统计。感觉上容易刺激的总体相似性排序也明显高于感觉上困难的刺激。实验2b还表明，预接触增加了感知上容易刺激的可分辨性，但是对于感知上困难的刺激，这种作用在统计学上无法检测到。实验3建立了预曝光效果还受刺激尺寸的空间分离性影响的结果-当将尺寸集成到一个连贯的物体中时，预曝光的整体相似性排序显着提高，而当它们在空间上分离时，预相似效果却没有显着提高。同样，在预曝光后，空间整合刺激的可辨别性在统计学上有显着提高，但对于空间分离刺激则没有。综上所述，这些结果表明，预暴露可以提高总体相似性排序，并深入了解发生效应的条件。
