Gating features into actions II

BRAC, Frings et al., 2020)认为：(1)情景特征绑定和检索为人类行为控制的基本过程提供了一个统一的视角；(2)绑定和检索应该在理论上被概念化为独立的过程；(3)绑定和检索分别受到自上而下控制和自下而上因素的影响。因此，BRAC框架提供了一个整合和创新的框架，可用于解释一系列范式特异性实验效应。在研究单元的第一阶段，该项目专门通过对绑定和检索分开分析来确定BRAC框架。在这个项目的第二阶段，我们将继续我们的方法来解开绑定与检索的纠缠，从而更好地理解“特征是如何被限定为动作的”。关于研究股第二阶段的一般做法，我们在此遵循两种不同的战略。首先，我们将进一步指定绑定与检索。虽然第一阶段的实验提供了令人信服的证据，表明绑定和检索过程可以根据行为部分重复的成本效应在响应时间和/或准确性上分开，但我们在特定情况下也达到了极限。因此，我们将扩展我们的方法，并研究与刺激-反应（S-R）结合相关的整合、解体和检索过程的电生理（EEG）相关性。我们认为-特别是在最近的研究背景下使用脑电图结合范式-我们必须进一步查明特征结合与情景检索。其次，我们将通过将绑定与检索逻辑应用于不同的实验范式来测试BRAC的范围，该实验范式来自于不关注动作控制的文献，即视觉搜索文献。特别是，我们将研究视觉搜索中的审间启动效应（例如，Zehetleitner et al., 2012），并试图为其中的绑定和检索分离产生证据，从而扩展BRAC框架的解释价值。

The Binding and Retrieval in Action Control framework (BRAC, Frings et al., 2020) suggests that (1) episodic feature binding and retrieval provide a unitary perspective on basic processes underlying human action-control, that (2) binding and retrieval should be conceptualized as theoretically separate processes, and that (3) binding and retrieval are independently affected by top-down control and bottom-up factors. The BRAC framework thus offers an integrative and innovative framework that can be used to explain a whole array of paradigm-specific experimental effects. In the first phase of the Research Unit, this project specifically contributed to specifying the BRAC framework by analyzing binding and retrieval separately. In the second phase of this project, we continue our approach to disentangle binding versus retrieval and thus better understand how ‘features are gated into actions’. Related to the general approach of the Research Unit’s second phase we follow two different strategies here. First, we will further specify binding versus retrieval. Although the experiments of the first phase provided compelling evidence that binding and retrieval processes can be separated based on behavioral partial repetition cost effects in response time and/or accuracy we also hit the limit at particular instances. Thus, we will expand our methodical approach and investigate the electrophysiological (EEG) correlates of integration, disintegration, and retrieval processes related to stimulus-response (S-R) binding. We think – especially against the background of recent studies using the EEG in binding paradigms – that we must further pinpoint feature binding versus episodic retrieval. Second, we will test BRAC’s reach by applying the binding versus retrieval logic to a different experimental paradigm from a literature that does not focus on action control, namely the visual search literature. In particular, we will look into intertrial priming effects (e.g., Zehetleitner et al., 2012) in visual search and try to generate evidence for the separation of binding and retrieval there, thereby extending the explanatory value of the BRAC framework.
