Eye movements (EMs) offer valuable insights into cognitive and perceptual processes, serving as potential biomarkers for disordered thinking. This study explores the relationship between EM indices and perception and thinking problems in the Rorschach Performance Assessment System (R-PAS). Sixty non-clinical participants underwent eye-tracking while completing the Rorschach test, focusing on variables from the Perception and Thinking Problems Domain (e.g., WSumCog, SevCog, FQo%). The results reveal that increased cognitive disturbances were associated with greater exploratory activity but reduced processing efficiency. Regression analyses highlighted the strong predictive role of cognitive variables (e.g., WSumCog) over perceptual ones (e.g., FQo%). Minimal overlap was observed between performance-based (R-PAS) and self-report measures (BSI), underscoring the need for multi-method approaches. The findings suggest that EM patterns could serve as biomarkers for early detection and intervention, offering a foundation for future research on psychotic-spectrum processes in clinical and non-clinical populations.
眼动（EMs）为认知和感知过程提供了有价值的见解，可作为思维紊乱的潜在生物标志物。本研究探讨了眼动指标与罗夏墨迹测验表现评估系统（R-PAS）中感知和思维问题之间的关系。60名非临床参与者在完成罗夏墨迹测验时接受了眼动追踪，重点关注感知和思维问题领域的变量（如WSumCog、SevCog、FQo%）。结果显示，认知障碍增加与探索活动增多但处理效率降低有关。回归分析突出了认知变量（如WSumCog）比感知变量（如FQo%）具有更强的预测作用。基于表现的（R-PAS）和自我报告测量（BSI）之间观察到最小重叠，强调了采用多方法途径的必要性。研究结果表明，眼动模式可作为早期检测和干预的生物标志物，为未来临床和非临床人群中精神病性谱系过程的研究奠定基础。
