控制反应参数,如反应的速度和准确性,使我们能够根据特定的情境任务要求调整我们的行为。我们研究了速度-准确性设置的认知控制是否不完全基于有意识的表征,但也可以由非有意识表征的刺激引起。参与者被指示指向并点击一个目标,在每次响应之前都有一个提示信号,是否优先考虑响应的准确性而不是速度,反之亦然。在一半的试验中,线索被掩盖,以防止有意识的代表性的线索。与可见的线索,反应模式表现出典型的速度-准确性权衡,速度线索后,更快,更准确的反应,更慢,但更准确的反应后,准确性线索。至关重要的是,这也是在掩蔽线索中发现的。我们的结果与最近关于意识与任务集激活和反应抑制等认知控制过程关系的发现一致:掩蔽线索能够影响认知控制过程。
Controlling response parameters like the speed and accuracy of responses allows us to adjust our behavior according to particular situational task demands. We investigated whether exertion of cognitive control over speed–accuracy settings is not exclusively based on conscious representations, but can also be elicited by stimuli that are not consciously represented. Participants were instructed to point and click on a target, with a cue signaling before each response whether to prioritize accuracy of the response over speed, or vice versa. In half of the trials, the cue was masked to prevent a conscious representation of the cue. With visible cues, response patterns showed typical speed–accuracy tradeoffs, with faster and less accurate responses after speed cues, and slower but more accurate responses after accuracy cues. Crucially, this was found with masked cues as well. Our results are in line with recent findings on the relation of consciousness and cognitive control processes like task-set activation and response inhibition: masked cues are able to impact on cognitive control processes.
