Summary
This study investigates the relationship between cognitive abilities—specifically spatial abilities and visuospatial memory—and performance in motor-imagery brain-computer interfaces (MI-BCI). The research addresses the issue of "BCI illiteracy," where a significant portion of novice users fail to generate the necessary brain activity patterns to control the system. While previous studies suggested correlations between spatial skills and BCI performance, they often utilized small sample sizes or inconsistent task paradigms. This work aims to clarify these relationships using a larger cohort and a standard two-class motor imagery task. The experimental design involved 54 novice participants who completed two cognitive assessments and a MI-BCI task. Spatial ability was measured using the Mental Rotation Test (MRT), while visuospatial memory was assessed via the Design Organization Test (DOT). For the BCI component, participants performed a left-versus-right hand motor imagery task using EEG signals recorded from 16 electrodes. The protocol included one calibration run and three feedback runs, with classification performed using Common Spatial Patterns and Linear Discriminant Analysis. Data analysis involved correlation tests between cognitive scores and BCI error rates, as well as group comparisons between high and low aptitude users defined by median error rates. The results indicated no significant correlation between BCI error rates and scores on either the Mental Rotation Test or the Design Organization Test. Furthermore, gender did not significantly impact BCI performance or MRT scores. However, when comparing high and low aptitude BCI users, a significant difference was found in visuospatial memory: high-performing users scored significantly higher on the DOT than low-performing users. In contrast, there was no significant difference in Mental Rotation scores between the two performance groups. The findings suggest that while spatial abilities as measured by mental rotation do not predict MI-BCI performance, visuospatial memory is a distinguishing factor between efficient and inefficient users. This contradicts some prior literature that found correlations with mental rotation, potentially due to differences in task design or sample size. The study concludes that visuospatial memory may be a more reliable indicator of BCI aptitude than general spatial ability. These insights imply that screening for visuospatial memory or incorporating targeted cognitive training could optimize MI-BCI training paradigms and help mitigate BCI illiteracy. The authors recommend future large-scale studies with extended training periods to further validate these cognitive predictors.
