Abstract

Real-world environments are complex, demanding a diverse set of cognitive functions such as attention and working memory (WM) to perform adaptive behaviors. However, exogenous attention, characterized as automatic and involuntary, has primarily been studied by focusing on spatial perception. In particular, the ability of pure exogenous retro-cues to select and prioritize not only spatial locations, but also novel stimulus–response (S-R) bindings held in WM remains largely unexplored. Here, in two experimental series, we provide evidence that pure exogenous non-predictive retro-cues can select not only space, but also associated S-R bindings held in WM. Additional evidence from a drift–diffusion model hinted at the possibility that the mechanisms through which exogenous attention selects and prioritizes WM contents depend, at least partially, on the hierarchical relevance of the different dimensions encoded within a specific representation. These results highlight the relationship between pure exogenous attention and complex WM contents and shed light on current theoretical debates about the interaction of attention, memory, and action.

外源性空间注意力在工作记忆中选择相关的新绑定内容
现实世界的环境错综复杂,需要注意力和工作记忆(WM)等多种认知功能来完成适应性行为。然而,外源性注意的特点是自动和非自主的,其研究主要集中在空间感知方面。特别是,纯粹的外源性反向线索不仅能选择空间位置,还能优先选择工作记忆中的新刺激-反应(S-R)绑定,但这种能力在很大程度上仍未得到研究。在这里,我们通过两个实验系列提供了证据,证明纯外源性非预测性逆向线索不仅能选择空间,还能选择 WM 中的相关 S-R 结合。来自漂移扩散模型的其他证据暗示,外源性注意选择和优先考虑 WM 内容的机制至少部分取决于特定表征中编码的不同维度的层次相关性。这些结果突显了纯粹的外源性注意与复杂的 WM 内容之间的关系,并为当前有关注意、记忆和行动相互作用的理论辩论提供了启示。

期刊介绍: Articles in the Journal of Memory and Language contribute to the formulation of scientific issues and theories in the areas of memory, language comprehension and production, and cognitive processes. Special emphasis is given to research articles that provide new theoretical insights based on a carefully laid empirical foundation. The journal generally favors articles that provide multiple experiments. In addition, significant theoretical papers without new experimental findings may be published. The Journal of Memory and Language is a valuable tool for cognitive scientists, including psychologists, linguists, and others interested in memory and learning, language, reading, and speech. Research Areas include: • Topics that illuminate aspects of memory or language processing • Linguistics • Neuropsychology.
