摘要

在人类的感知决策中,速度-准确性权衡在紧迫性和准确性降低之间建立了因果联系。至于速度与视觉图像的主观评价之间的关系,人们则知之甚少。在此,我们进行了一组四项实验,以揭示速度与主观评价之间关系的两种不同假设。速度-两极分化权衡 "假设意味着紧迫性会导致更多的两极分化评价。与此相反,"易处理 "假设认为,速度与两极化之间的任何关联都是由于与评价相关的图像内容的显著性造成的。内容越突出,处理起来就越容易,因此评价也就越快、越极端。在每个实验中,我们都要求参与者对图像进行从-10到+10的连续评价,并测量他们的反应时间;在实验1-3中,参与者对现实世界中的图像进行道德评价(从 "非常不道德"-10到 "非常道德 "+10);在实验4中,参与者对食物图像进行食欲评价(从 "非常恶心"-10到 "非常诱人 "+10)。在实验 1、3 和 4 中,我们使用了提示程序,逐次告知被试他们是可以进行自定步调(SP)评价,还是必须在 2 秒钟内进行限时(TL)评价。与 SP 条件相比,TL 条件下的反应速度始终要快得多,这表明我们的紧迫性操纵是成功的。然而,比较 SP 和 TL 条件,我们发现在任何评价中都没有显著差异。然而,所报告的道德评价处理的难易程度与反应速度和评价的极化程度都有很大关系。数据的总体模式表明,虽然速度与极化有关,但紧迫性并不会导致参与者做出更极端的评价。相反,速度与极化之间的关联反映了处理的难易程度。与解释不确定的图像相比,易于评价的图像会引起更快和更极端的评分。

Speed is associated with polarization during subjective evaluation: no tradeoff, but an effect of the ease of processing

In human perceptual decision-making, the speed-accuracy tradeoff establishes a causal link between urgency and reduced accuracy. Less is known about how speed relates to the subjective evaluation of visual images. Here, we conducted a set of four experiments to tease apart two alternative hypotheses for the relation between speed and subjective evaluation. The hypothesis of “Speed-Polarization Tradeoff” implies that urgency causes more polarized evaluations. In contrast, the “Ease-of-Processing” hypothesis suggests that any association between speed and polarization is due to the salience of evaluation-relevant image content. The more salient the content, the easier to process, and therefore the faster and more extreme the evaluation. In each experiment, we asked participants to evaluate images on a continuous scale from − 10 to + 10 and measured their response times; in Experiments 1–3, the participants rated real-world images in terms of morality (from “very immoral,” -10, to “very moral,” +10); in Experiment 4, the participants rated food images in terms of appetitiveness (from “very disgusting,” -10, to “very attractive,” +10). In Experiments 1, 3, and 4, we used a cueing procedure to inform the participants on a trial-by-trial basis whether they could make a self-paced (SP) evaluation or whether they had to perform a time-limited (TL) evaluation within 2 s. In Experiment 2, we asked participants to rate the easiness of their SP moral evaluations. Compared to the SP conditions, the responses in the TL condition were consistently much faster, indicating that our urgency manipulation was successful. However, comparing the SP versus TL conditions, we found no significant differences in any of the evaluations. Yet, the reported ease of processing of moral evaluation covaried strongly with both the response speed and the polarization of evaluation. The overall pattern of data indicated that, while speed is associated with polarization, urgency does not cause participants to make more extreme evaluations. Instead, the association between speed and polarization reflects the ease of processing. Images that are easy to evaluate evoke faster and more extreme scores than images for which the interpretation is uncertain.

期刊介绍: Cognitive Neurodynamics provides a unique forum of communication and cooperation for scientists and engineers working in the field of cognitive neurodynamics, intelligent science and applications, bridging the gap between theory and application, without any preference for pure theoretical, experimental or computational models. The emphasis is to publish original models of cognitive neurodynamics, novel computational theories and experimental results. In particular, intelligent science inspired by cognitive neuroscience and neurodynamics is also very welcome. The scope of Cognitive Neurodynamics covers cognitive neuroscience, neural computation based on dynamics, computer science, intelligent science as well as their interdisciplinary applications in the natural and engineering sciences. Papers that are appropriate for non-specialist readers are encouraged. 1. There is no page limit for manuscripts submitted to Cognitive Neurodynamics. Research papers should clearly represent an important advance of especially broad interest to researchers and technologists in neuroscience, biophysics, BCI, neural computer and intelligent robotics. 2. Cognitive Neurodynamics also welcomes brief communications: short papers reporting results that are of genuinely broad interest but that for one reason and another do not make a sufficiently complete story to justify a full article publication. Brief Communications should consist of approximately four manuscript pages. 3. Cognitive Neurodynamics publishes review articles in which a specific field is reviewed through an exhaustive literature survey. There are no restrictions on the number of pages. Review articles are usually invited, but submitted reviews will also be considered.
