The paired t-test results showed that the prior cognitive level and transfer distance significantly impact FC.

Concretely, we discussed the prior cognitive level, knowledge transfer distance, and transfer performance impacting the wavelet amplitude and wavelet phase coherence. The neural activation of the prefrontal cortex was continuously recorded for 31 participants using functional near-infrared spectroscopy (fNIRS). In this study, we adopted the modified Wisconsin Card-Sorting Test (M-WCST) reported in the literature. Thus, this study proposed functional connectivity (FC) to describe and evaluate the dynamic brain network of knowledge transfer while engineering problem-solving. However, the neurophysiological mechanisms of knowledge transfer are rarely considered in existing studies. It is crucial to explain how the alteration of the functional brain network occurs and how to express it, which causes the alteration of the cognitive structure of knowledge transfer.
