在大多数情况下,大脑在施加注意力控制方面表现出非凡的能力,但在其他情况下也存在明显的局限性。我们的目标是构建一个合理的解释,为什么注意力控制出现次优冲突的条件下,它意味着什么的基本计算原则。我们采用的正式框架是基于贝叶斯概率理论,它提供了一个方便的语言描绘的注意力选择的基本原理和动态。我们说明这些问题使用埃里克森侧翼任务,一个经典的范式,探讨竞争的感官输入的反应倾向的影响。我们展示了两个不同的制定模型,基于兼容性偏差和空间不确定性原则,可以解释的行为数据。我们还提出了新的实验,可以区分这些模型。此外,我们详细阐述了一个简化的模型,近似最佳计算,并可能更直接地映射到底层神经机制。这个近似模型使用冲突监测,pupelium介导的前扣带皮层,作为代理的兼容性表示。我们还考虑如何传播这种冲突的信息,并用于控制处理。
The brain exhibits remarkable facility in exerting attentional control in most circumstances, but it also suffers apparent limitations in others. Our goal is to construct a rational account for why attentional control appears sub-optimal under conditions of conflict, and what it implies about the underlying computational principles. The formal framework we employ is based on Bayesian probability theory, which provides a convenient language for delineating the rationale and dynamics of attentional selection. We illustrate these issues using the Eriksen flanker task, a classical paradigm that explores the effects of competing sensory inputs on response tendencies. We show how two distinctly formulated models, based on compatibility bias and spatial uncertainty principles, can account for the behavioral data. We also suggest novel experiments that may differentiate these models. In addition, we elaborate a simplified model that approximates optimal computation, and may map more directly onto the underlying neural machinery. This approximate model uses conflict monitoring, putatively mediated by the anterior cingulate cortex, as proxy for compatibility representation. We also consider how this conflict information might be disseminated and used to control processing.
