Many studies have shown that language can affect visual perception; however, our understanding of the neural basis of linguistic influence is inadequate. This can be investigated by examining the hemispheric asymmetry of linguistic influence. The left and right hemispheres are dominant in close and distant semantic processing, respectively. In this study, we investigated whether the hemispheric asymmetry of semantic processing led to hemispheric asymmetry for concept priming on the detection of objects degraded by continuous flash suppression. We combined a priming paradigm with the divided visual field paradigm and used continuous flash suppression, which renders objects invisible. The results indicated that the hemispheric asymmetry of semantic processing led to a right lateralization in the influence of more abstract concepts on visual perception. The lateralization of brain connectomes may be the underlying neural basis of this effect.
许多研究表明，语言会影响视觉感知；然而，我们对语言影响的神经基础的理解并不充分。这可以通过研究语言影响的半球不对称性来进行探究。左半球和右半球分别在近义语义处理和远义语义处理中占主导地位。在本研究中，我们调查了语义处理的半球不对称性是否会导致在检测因连续闪光抑制而退化的物体时，概念启动方面的半球不对称性。我们将启动范式与视野分割范式相结合，并使用连续闪光抑制，使物体不可见。结果表明，语义处理的半球不对称性导致更抽象的概念对视觉感知的影响出现右侧化。脑连接组的这种侧化可能是这种效应的潜在神经基础。
