Most recent research on human tool use highlighted how people might integrate multiple sources of information through different neurocognitive systems to exploit the environment for action. This mechanism of integration is known as "action reappraisal". In the present eye-tracking study, we further tested the action reappraisal idea by devising a word-priming paradigm to investigate how semantically congruent (e.g., "nail") vs. semantically incongruent words (e.g., "jacket") that preceded the vision of tools (e.g., a hammer) may affect participants' visual exploration of them. We found an implicit modulation of participants' temporal allocation of visuospatial attention as a function of the object-word consistency. Indeed, participants tended to increase over time their fixations on tools' manipulation areas under semantically congruent conditions. Conversely, participants tended to concentrate their visual-spatial attention on tools' functional areas when inconsistent object-word pairs were presented. These results support and extend the information-integrated perspective of the action reappraisal approach. Also, these findings provide further evidence about how higher-level semantic information may influence tools' visual exploration.
最近关于人类工具使用的研究强调了人们如何通过不同的神经认知系统整合多种信息源，以利用环境进行行动。这种整合机制被称为“动作再评价”。在本眼动研究中，我们通过设计一个单词启动范式进一步测试了动作再评价的想法，以调查在工具（如锤子）出现之前，语义上一致的（例如“钉子”）与语义上不一致的词（例如“夹克”）如何影响参与者对工具的视觉探索。我们发现，参与者的视觉空间注意力的时间分配随着物体-单词一致性的变化而发生了隐性的调节。事实上，在语义一致的条件下，参与者随着时间的推移，会增加对工具操作区域的注视次数。相反，当呈现不一致的物体-单词对时，参与者往往会将视觉注意力集中在工具的功能区域上。这些结果支持并扩展了动作再评价方法的信息整合观点。此外，这些发现进一步证明了高级语义信息如何影响工具的视觉探索。
