Abstract

In the present study, we investigated the influence of performance-contingent reward prospects on task performance across three visual conflict tasks with manual responses (Experiments 1 & 2: Simon and Stroop tasks; Experiment 3: Simon and Eriksen flanker task) using block-wise (Experiment 1) and trial-wise (Experiments 2 & 3) manipulations to signal the possibility of reward. Across all experiments, task performance (in reaction time and/or error rates) generally improved in reward compared with no-reward conditions in each conflict task. However, there was, if any, little evidence that the reward manipulation modulated the size of the mean conflict effects, and there was also no evidence for conflict-specific effects of reward when controlling for time-varying fluctuations in conflict processing via distributional analyses (delta plots). Thus, the results provide no evidence for conflict-specific accounts and instead favor performance-general accounts, where reward anticipation leads to overall performance improvements without affecting conflict effects. We discuss possible implications for how proactive control might modulate the interplay between target- and distractor-processing in conflict tasks.

冲突任务中的主动奖励:它只能提高一般表现,还是也能调节冲突效果?
在本研究中,我们利用分块(实验 1)和分次(实验 2 和 3)操作来提示奖励的可能性,研究了在三项手动反应的视觉冲突任务(实验 1 和 2:西蒙和斯特罗普任务;实验 3:西蒙和埃里克森侧翼任务)中,与表现相关的奖励前景对任务表现的影响。在所有实验中,在每个冲突任务中,与无奖励条件相比,有奖励条件下的任务表现(反应时间和/或错误率)普遍有所提高。然而,几乎没有证据表明奖励操作调节了平均冲突效应的大小,而且通过分布分析(△图)控制冲突处理中的时变波动时,也没有证据表明奖励具有特定冲突效应。因此,这些结果并没有为冲突特异性解释提供证据,而是倾向于表现一般解释,即奖励预期会导致整体表现的提高,而不会影响冲突效应。我们讨论了主动控制如何调节冲突任务中目标和分心处理之间相互作用的可能影响。

期刊介绍: The journal Attention, Perception, & Psychophysics is an official journal of the Psychonomic Society. It spans all areas of research in sensory processes, perception, attention, and psychophysics. Most articles published are reports of experimental work; the journal also presents theoretical, integrative, and evaluative reviews. Commentary on issues of importance to researchers appears in a special section of the journal. Founded in 1966 as Perception & Psychophysics, the journal assumed its present name in 2009.
