Abstract

The present study sought to investigate whether working memory (WM) load influences the spatial congruency effect in audiovisual (AV) integration using simple stimuli. Participants completed an AV localization task under three WM load conditions (0-back, 1-back, 2-back), Spatially congruent AV stimuli consistently facilitated responses regardless of working memory (WM) load. Statistical analyses found no significant interactions between WM load and audiovisual integration for reaction time (RT), accuracy, sensitivity (d'), or auditory enhancement effects (p < 0.05). Critically, Bayesian analysis in the present study provided strong evidence against the existence of such an interaction (BF ≈ 0.0001), although independent replication is warranted to confirm this finding. These findings indicate that spatially congruent AV integration is robust across different levels of working memory load, suggesting that it occurs at a low-level perceptual stage and is automatic.

简单刺激的视听整合：空间一致性效应不受工作记忆负荷影响。

本研究旨在探讨工作记忆负荷是否影响简单刺激下的视听整合空间一致性效应。被试在工作记忆（WM）负荷条件下完成了视像定位任务，结果表明，空间一致性视像刺激对视像定位的促进作用与工作记忆负荷无关。统计分析发现，WM负荷与视听整合在反应时间（RT）、准确性、灵敏度（d'）或听觉增强效应方面没有显著的相互作用（p < 0.05）。重要的是，本研究中的贝叶斯分析提供了强有力的证据，反对这种相互作用的存在（BF≈0.0001），尽管有必要进行独立的复制来证实这一发现。这些研究结果表明，空间一致性视音频整合在不同工作记忆负荷水平上都是稳健的，表明它发生在低水平知觉阶段，并且是自动的。

期刊介绍： Frontiers in Psychology is the largest journal in its field, publishing rigorously peer-reviewed research across the psychological sciences, from clinical research to cognitive science, from perception to consciousness, from imaging studies to human factors, and from animal cognition to social psychology. Field Chief Editor Axel Cleeremans at the Free University of Brussels is supported by an outstanding Editorial Board of international researchers. This multidisciplinary open-access journal is at the forefront of disseminating and communicating scientific knowledge and impactful discoveries to researchers, academics, clinicians and the public worldwide. The journal publishes the best research across the entire field of psychology. Today, psychological science is becoming increasingly important at all levels of society, from the treatment of clinical disorders to our basic understanding of how the mind works. It is highly interdisciplinary, borrowing questions from philosophy, methods from neuroscience and insights from clinical practice - all in the goal of furthering our grasp of human nature and society, as well as our ability to develop new intervention methods.
