Adapting flexibly to recent events is essential in everyday life. A robust measure of such adaptive behavior is the congruency sequence effect (CSE) in the prime-probe task, which refers to a smaller congruency effect after incongruent trials than after congruent trials. Prior findings indicate that the CSE in the prime-probe task reflects control processes that modulate response activation after the prime onsets but before the probe appears. They also suggest that similar control processes operate even in a modified prime-probe task wherein the initial prime is a relevant target, rather than merely a distractor. Because adaptive behavior frequently occurs in the absence of irrelevant stimuli, the present study investigates the nature of the control processes that operate in this modified prime-probe task. Specifically, it investigates whether these control processes modulate only the response cued by the prime (response-specific control) or also other responses (response-general control). To make this distinction, we employed a novel variant of the modified prime-probe task wherein primes and probes are mapped to different responses (i.e., effectors), such that only response-general control processes can engender a CSE. Critically, we observed a robust CSE in each of 2 experiments. This outcome supports the response-general control hypothesis. More broadly, it suggests that the control processes underlying the CSE overlap with general mechanisms for adapting to sequential dependencies in the environment.

修改后的主要探针任务中的一致性序列效应指示响应-一般控制。

灵活地适应最近发生的事件是日常生活中必不可少的。这种适应性行为的一个稳健的衡量标准是主探针任务中的一致性序列效应 (CSE),它指的是不一致试验后的一致性效应比一致试验后更小。先前的研究结果表明,初始探针任务中的 CSE 反映了在初始启动之后但在探针出现之前调节响应激活的控制过程。他们还建议,即使在修改过的初始探针任务中,类似的控制过程也会运行,其中初始初始是相关目标,而不仅仅是干扰项。因为适应性行为经常发生在没有无关刺激的情况下,本研究调查了在这个修改后的主探针任务中运行的控制过程的性质。具体来说,它研究这些控制过程是否仅调节由素数(响应特定控制)或其他响应(响应-一般控制)提示的响应。为了区分这一点,我们采用了一种改进的质数-探针任务的新变体,其中质数和探针被映射到不同的响应(即效应器),这样只有响应-一般控制过程才能产生 CSE。至关重要的是,我们在 2 个实验中的每一个中都观察到了强大的 CSE。该结果支持响应-一般控制假设。更广泛地说,它表明 CSE 背后的控制过程与适应环境中顺序依赖性的一般机制重叠。(PsycInfo 数据库记录 (c) 2020 APA,保留所有权利)。
