As car expertise increases, so does interference between the visual processing of faces and that of cars; this suggests performance trade-offs across domains of real-world expertise. Such interference between expert domains has been previously revealed in a relatively complex design, interleaving 2-back part-judgment task with faces and cars (Gauthier et al., 2003). However, the basis of this interference is unclear. Experiment 1A replicated the finding of interference between faces and cars, as a function of car expertise. Experiments 1B and 2 investigated the mechanisms underlying this effect by (1) providing baseline measures of performance and (2) assessing the specificity of this interference effect. Our findings support the presence of expertise-dependent interference between face and non-face domains of expertise. However, surprisingly, it is in the condition where faces are processed among cars with a disrupted configuration where expertise has a greater influence on faces. This finding highlights how expertise-related processing changes also occur for transformed objects of expertise and that such changes can also drive interference across domains of expertise.
随着汽车专业知识的增加，面部和汽车的视觉处理之间的干扰也会增加；这表明在实际专业知识领域存在表现上的权衡取舍。在一个相对复杂的设计中，之前已经揭示了这种专家领域之间的干扰，该设计将 2 回部分判断任务与面孔和汽车交织在一起（Gauthier 等人，2003 年）。然而，这种干扰的基础尚不清楚。实验 1A 复制了面孔和汽车之间干扰的发现，这是汽车专业知识的一个功能。实验 1B 和 2 通过（1）提供性能的基线测量和（2）评估这种干扰效应的特异性来研究这种效应的机制。我们的发现支持了面孔和非面孔专业知识领域之间存在依赖专业知识的干扰。然而，令人惊讶的是，在面孔在配置中断的汽车中被处理的情况下，专业知识对面孔的影响更大。这一发现强调了专业知识相关的处理变化也会发生在专业知识的变形物体上，并且这种变化也会在专业知识领域之间产生干扰。
