反应抑制的计算模型中的独立性的基石假设被严重违反。停止信号范式是理解认知控制和反应抑制的主要实验范式,它依赖于竞赛模型的理论基础,该模型假设在停止信号延迟(SSD)之后发生的停止过程独立地与进行过程竞赛。我们发现,严重违反这种独立性假设在短SSD系统地发生在广泛的条件下,包括快速和缓慢的反应时间,听觉和视觉停止信号,手动和扫视反应,特别是在选择性停止。我们还重新分析了现有数据,并表明当排除短SSD时,结论可能会发生变化。最后,我们建议实验和分析技术来解决这种违反,并提出调整现有的模型,以适应这一发现。
The keystone assumption of independence in computational models for response inhibition is severely violated. The stop-signal paradigm, a primary experimental paradigm for understanding cognitive control and response inhibition, rests upon the theoretical foundation of race models, which assume that a go process races independently against a stop process that occurs after a stop-signal delay (SSD). We show that severe violations of this independence assumption at short SSDs occur systematically across a wide range of conditions, including fast and slow reaction times, auditory and visual stop signals, manual and saccadic responses, and especially in selective stopping. We also reanalyze existing data and show that conclusions can change when short SSDs are excluded. Last, we suggest experimental and analysis techniques to address this violation, and propose adjustments to extant models to accommodate this finding.
