最近的研究强调了一种特定形式的因果理解，即技术推理，如何支持人类几代人开发的工具和技术日益复杂，即，累积技术文化（CTC）。因此，研究技术推理的神经认知基础对于理解CTC在我们谱系中的出现至关重要。虽然功能性神经影像学证据开始强调左下顶叶皮层（IPC）PF区在技术推理中的关键作用，但没有研究探讨这样一个大脑区域的结构特征与技术推理技能之间的联系。因此，在这项研究中，我们通过使用两个特别的心理技术测试来评估参与者的技术推理表现;然后，我们从参与者的3 T T1加权磁共振脑图像中提取皮质厚度（即，与认知表现相关的体积相关测量，反映了大脑区域中细胞的大小、密度和排列）。我们发现左侧PF区的皮质厚度预测了参与者的技术推理表现。至关重要的是，我们报告技术推理与其他IPC区域之间没有相关性，这可能表明左侧PF区域在生成技术知识方面的特异性。我们从进化的角度来讨论这些发现，通过推测顶叶的进化可能支持了我们血统中技术推理的出现。
Most recent research highlights how a specific form of causal understanding, namely technical reasoning, may support the increasing complexity of tools and techniques developed by humans over generations, i.e., the cumulative technological culture (CTC). Thus, investigating the neurocognitive foundations of technical reasoning is essential to comprehend the emergence of CTC in our lineage. Whereas functional neuroimaging evidence started to highlight the critical role of the area PF of the left inferior parietal cortex (IPC) in technical reasoning, no studies explored the links between the structural characteristics of such a brain region and technical reasoning skills. Therefore, in this study, we assessed participants’ technical-reasoning performance by using two ad-hoc psycho-technical tests; then, we extracted from participants’ 3 T T1-weighted magnetic-resonance brain images the cortical thickness (i.e., a volume-related measure which is associated with cognitive performance as reflecting the size, density, and arrangement of cells in a brain region) of all the IPC regions for both hemispheres. We found that the cortical thickness of the left area PF predicts participants’ technical-reasoning performance. Crucially, we reported no correlations between technical reasoning and the other IPC regions, possibly suggesting the specificity of the left area PF in generating technical knowledge. We discuss these findings from an evolutionary perspective, by speculating about how the evolution of parietal lobes may have supported the emergence of technical reasoning in our lineage.
