Summary
This study investigates how neural markers of cognitive engagement shift between guided training and unguided application phases under varying cognitive workloads in a virtual reality (VR) environment. The research addresses a critical gap in training design: determining whether learners actively engage cognitive resources necessary for skill transfer or merely follow instructions. Specifically, the authors examined how intrinsic load (task complexity) and extraneous load (non-essential instructional details) interact with task phases to influence engagement, aiming to inform the development of adaptive training systems that monitor neural states to optimize learning transfer. The experimental design involved 23 participants performing a VR shape-assembly task across four within-subject conditions defined by low or high intrinsic and extraneous loads. The study comprised two phases: a training phase with adaptive, step-by-step instructions that gradually faded to require memory reliance, and an application phase where participants assembled the object from memory without guidance or feedback. Electroencephalography (EEG) was recorded using an eight-channel system to derive three engagement indicators: Cognitive Effort (parietal α/frontal θ ratio), Sustained Attention (β/(α + θ) ratio), and Integration & Execution (γ-band power). Performance metrics and NASA-TLX self-reports confirmed that workload manipulations effectively altered cognitive demand and training time. Results revealed distinct neural patterns between phases. Contrary to the hypothesis that training would elicit higher sustained attention, the Sustained Attention indicator was significantly lower during training than application, except under high combined workload conditions where training engagement increased. The Integration & Execution indicator showed robustly higher activation during application across all conditions, particularly at the frontal electrode (Fz), suggesting heightened working memory and integrative processing when external cues were removed. The Cognitive Effort indicator showed no significant main effects or interactions. Significant interactions between task phase and workload conditions emerged for Sustained Attention and Integration & Execution, indicating that the neural response to unguided application depends on the type of cognitive load experienced during training. The findings demonstrate that moving from guided practice to autonomous application triggers a shift in neural engagement, specifically amplifying integrative and executive processes. This supports the utility of EEG markers in distinguishing between passive following of instructions and active cognitive integration. The study concludes that adaptive training systems could leverage these neural signatures—such as γ-band power increases—to dynamically adjust scaffolding or instructional clarity. By identifying when learners are engaging in germane cognitive processing versus struggling with extraneous load, such systems could optimize the transition from training to real-world application, enhancing skill retention and transfer in high-stakes domains like aerospace and healthcare.
