Preregistration. Context-Triggered Retrieval in Task Switching: Advancing a Hybrid Binding–Inhibition Account

Recent task-switching studies highlighted the presence of feature binding processes. These studies documented that even a task-irrelevant feature (the context, henceforth) may be bound with the task and the response in each trial. When the context repeated in the following trial, it supposedly retrieved the bound features, causing benefits when the task and the response repeated and costs otherwise (i.e. full repetition benefits). Previous work suggested that full repetition benefits when the context repeated were found only when the context appeared early enough during the trial timeline to yield binding effects (Benini et al., 2023, 2024). However, in these studies, a delayed context onset implied a shorter context presentation duration (with one exception, namely Exp. 2 of Benini et al., 2023). This is the second of two experiments, where we introduced a stimulus-onset asynchrony (SOA) manipulation between the cue and the context onset. Specifically, we investigate the effect of presenting the context before, with, or after the cue but keeping constant the total context presentation duration. The results of Experiment 1 show no effect of the SOA. Note, however, that we could not replicate the full repetition benefits in the reaction times; rather, we observed in the error rates that repeating a context increased the response-repetition costs in task switches. Therefore, in the present study we investigate the robustness of these results (i.e., no effect of SOA and an increase of response-repetition costs with a context repetition), in particular emphasizing both accuracy and speed equally in the instructions. unknown other

近期的任务切换研究揭示了特征绑定过程的存在。此类研究证实，即便任务无关特征（下称情境），也可在每一试次中与任务及反应形成绑定。当后续试次重复呈现该情境时，理论上会触发已绑定特征的提取：若任务与反应均重复，则会产生收益；反之则会带来代价（即完全重复收益）。既往研究表明，仅当情境在试次时序中出现得足够早以产生绑定效应时，重复呈现情境才会带来完全重复收益（Benini等，2023、2024）。然而在上述研究中，延迟的情境起始时间往往意味着更短的情境呈现时长（Benini等2023年的实验2为唯一例外）。本研究为两项系列实验的第二篇，我们在线索与情境起始之间设置了刺激呈现异步性（stimulus-onset asynchrony, SOA）操纵。具体而言，我们旨在探究：在保持情境总呈现时长恒定的前提下，将情境呈现在线索之前、同时或之后所产生的效应。实验1的结果未观测到SOA存在显著效应。但需注意，本研究未能在反应时指标中复现完全重复收益；相反，我们在错误率指标中观察到：当情境重复时，任务切换试次下的反应重复代价会显著升高。因此，本研究旨在验证上述结果的稳健性（即SOA无显著效应、情境重复会升高反应重复代价），并在实验指导语中对准确性与速度予以同等权重要求。其余信息未明确。
