Summary
This study investigates the role of attentional capacity in visuomotor adaptation to a virtual reality (VR) driving simulator. While previous research established that adapting to VR driving environments requires significant mental effort and varies widely among individuals, the specific cognitive factors driving these inter-individual differences remained unclear. The authors hypothesized that individuals with higher attentional capacity would exhibit more efficient adaptation to novel virtual driving circumstances, as the initial discrepancy between actual and desired performance demands substantial cognitive resources. To test this hypothesis, participants performed a steering task involving 100 right-hand bends in a VR simulator, aiming to keep their vehicle within a central 0.25-meter zone. Adaptation was measured by changes in steering performance (time spent in the zone), steering stability (lateral position variance), and steering reversal rate (frequency of direction changes) across ten blocks of trials. Attentional capacity was assessed using two dynamic visual attention tasks: Multiple Object Tracking (MOT) and Multiple Object Avoidance (MOA). Mental effort was also monitored using the Rating Scale for Mental Effort (RSME). The results confirmed that participants effectively adapted to the simulator, with steering performance and stability improving significantly over the course of the trials, while mental effort decreased after the initial block. Crucially, both MOT and MOA scores significantly predicted the degree of adaptation, with MOT emerging as the stronger predictor. Regression analyses revealed that higher attentional capacity was associated with better steering outcomes. Specifically, participants with higher MOT scores produced more low-amplitude steering-wheel corrections early in the task, leading to finer vehicle control and superior performance in later blocks. In contrast, participants with lower attentional capacities showed little variation in performance across blocks, indicating a ceiling effect or limited adaptive capability. Control analyses showed that age, sex, and driving experience did not significantly predict adaptation time. These findings demonstrate that attentional capacity is a critical determinant of how efficiently individuals adapt to VR driving simulators. The study suggests that adaptation involves a two-stage mechanism: an initial phase of high mental effort and coarse control, followed by a phase of refined, stable steering. Individuals with robust attentional resources can better manage the initial cognitive load, allowing them to implement precise corrective strategies early on. This insight has implications for the design of driving simulators and the assessment of driver readiness, highlighting the utility of dynamic attention tasks like MOT in predicting individual differences in simulator adaptation.
Key finding
Individuals with higher attentional capacity, particularly as measured by Multiple Object Tracking scores, adapted more efficiently to the driving simulator by employing finer steering corrections early in the task.
