Our current perception and decision-making are shaped by recent experiences, a phenomenon known as serial dependence. While serial dependence is well-documented in visual perception and has been recently explored in time perception, their functional similarities across non-temporal and temporal domains remain elusive, particularly in relation to task relevance and working memory load. To address this, we designed a unified experimental paradigm using coherent motion stimuli to test both direction and time reproduction. The direction and time tasks were randomly mixed across trials. Additionally, we introduced pre-cue versus post-cue settings in separate experiments to manipulate working memory load during the encoding phase. We found attractive biases in time reproduction but repulsive biases in direction estimation. Notably, the temporal attraction was more pronounced when the preceding task was also time-related. In contrast, the direction repulsion remained unaffected by the nature of the preceding task. Additionally, both attractive and repulsive biases were enhanced by the post-cue compared to the pre-cue. Our findings suggest that opposing sequential effects in non-temporal and temporal domains may originate from different processing stages linked to sensory adaptation and post-perceptual processes involving working memory.
我们当前的感知和决策受到近期经验的影响，这一现象被称为序列依赖。虽然序列依赖在视觉感知中得到了很好的记录，并在时间感知中得到了最近的研究，但它们在非时间和时间领域的功能相似性仍然难以捉摸，特别是在与任务相关性和工作记忆负荷有关的方面。为了解决这个问题，我们设计了一个使用连贯运动刺激的统一实验范式，以测试方向和时间再现。方向和时间任务在试验中随机混合。此外，我们在单独的实验中引入了预提示和后提示设置，以在编码阶段操纵工作记忆负荷。我们发现时间再现存在吸引力偏差，但方向估计存在排斥力偏差。值得注意的是，当前面的任务也与时间有关时，时间的吸引力更为明显。相比之下，方向排斥不受前面任务性质的影响。此外，与预提示相比，后提示增强了吸引力和排斥力偏差。我们的发现表明，非时间和时间领域中的相反序列效应可能源于与感觉适应和涉及工作记忆的后知觉过程相关的不同处理阶段。
