Studies of event-related potentials show that the specific N170 response has become a stable electrophysiological hallmark of objects related to expertise in early perceptual processing. In the present study, we investigated whether eyeglasses can elicit N170 effects similar to those elicited by objects of expertise. Our results showed that the N170 response elicited by eyeglasses was larger than the response elicited by objects that do not generate perceptual expertise (e.g., houses). Importantly, we found that eyeglasses could produce a within-category N170 adaptation effect, similar to that produced in response to objects of expertise (e.g., faces). Our results have revealed for the first time that with a large amount of experience, eyeglasses could evoke the face-like N170 response, which suggested that eyeglasses may become an object of perceptual expertise to some human observers.
与事件相关电位的研究表明，特定的N170反应已成为早期感知处理中与专业知识相关物体的稳定电生理标志。在本研究中，我们调查了眼镜是否能引发与专业知识相关物体所引发的类似N170效应。我们的结果表明，眼镜引发的N170反应大于非产生感知专业知识物体（如房屋）引发的反应。重要的是，我们发现眼镜能够产生类别内N170适应效应，类似于对专业知识相关物体（如面孔）产生的效应。我们的结果首次揭示，通过大量经验，眼镜能够引发类似面孔的N170反应，这表明眼镜可能成为一些人类观察者的感知专业知识物体。
