复制任务促进时距知觉序列依赖跨通道效应
The duration reproduction task facilitates cross-modal serial dependence in duration perception
摘要
序列依赖反映了短时程的先前经验对后续感知加工的影响。本研究通过三个实验系统探究了时距复制任务中的序列依赖效应以及任务范式对时距知觉序列依赖跨通道效应的影响。结果发现：时距复制任务中先前刺激和复制时距能够分别导致排斥性的刺激序列依赖效应和吸引性的反应序列依赖效应；刺激和反应序列依赖效应在复制任务中表现出一定程度的跨通道性，在时距二分任务中则具有通道特异性。这些发现揭示了任务范式是影响时距知觉刺激和反应序列依赖跨通道效应的重要因素。这说明时距知觉的刺激序列依赖效应并非完全源于低水平的感知适应，其涉及高水平的认知加工；反应序列依赖效应并不是一种简单机械的决策惯性，其涉及对反应策略的整合利用。
Abstract
The serial dependence effect refers to the influence of immediately preceding experiences on subsequent perceptual processing. Previous research has identified two types of serial dependence in the duration bisection task: a repulsive stimulus serial dependence effect and an attractive response serial dependence effect. Notably, both effects have been shown to exhibit modality specificity, meaning they do not generalize across sensory modalities such as vision and audition. Considering the distinctions between duration bisection and duration reproduction tasks, it remains unclear whether similar stimulus and response serial dependence effects also occur in duration reproduction, and whether they generalize across sensory modalities. In the present study, we investigated serial dependence and its cross-modal effects in the duration reproduction task, and further assessed how task paradigm shapes cross-modal stimulus and response serial dependence in duration perception.The duration reproduction task and generalized linear models were used across three experiments. In Experiment 1, 24 participants with no prior exposure to the task completed visual and auditory duration reproduction tasks in separate blocks. Participants reproduced the duration of a test stimulusone of five durations ranging from 500 to 1200 ms in equal logarithmic stepsby pressing and holding a button for the matching duration. Experiment 2 involved a new group of 25 participants and followed a similar procedure, except that visual and auditory stimuli were pseudorandomly presented within a single block. In Experiment 3, 32 different participants completed both duration reproduction and duration bisection tasks. The reproduction task was identical to that in Experiment 2, while in the bisection task, participants judged whether the test stimulus was longer or shorter than an intermediate reference stimulus once it disappeared.The results of Experiment 1 showed that the previous stimulus and previous reproduction exerted opposite effects on serial dependence: current duration estimates were repelled by the prior stimulus duration (repulsive stimulus serial dependence) but attracted toward the prior reproduction (attractive response serial dependence). Experiment 2 further indicated that both stimulus and response serial dependence effects could partially generalize across visual and auditory modalities, contrasting with the modality-specific effects observed in earlier studies employing the duration bisection task. However, the test durations in Experiment 2 were longer than those typically employed in previous duration bisection tasks. To rule out any influence of test duration and to further investigate the impact of task paradigm on cross-modal serial dependence, we conducted Experiment 3. Consistent with Experiment 2, both stimulus and response serial dependence effects partially generalized across modalities in the duration reproduction task. In contrast, in the duration bisection task, both effects remained modality-specific, aligning with earlier studies. These findings suggest that task paradigm plays a crucial role in modulating cross-modal serial dependence in duration perception.These results provide evidence that both previous stimulus and previous responses affect subsequent duration perception, eliciting a repulsive stimulus serial dependence effect and an attractive response serial dependence effect, respectively. This indicates that distinct mechanisms underlie the use of prior stimulus and response information in duration processing. Moreover, task paradigm modulates the cross-modal effects of serial dependence in duration perception. One possible explanation is that reproduction response facilitates integration of visual and auditory temporal encoding, diminishing categorical distinctions between modalities and thereby promoting cross-modal stimulus and response serial dependence effects. These results indicate that stimulus serial dependence is not solely explained by low-level perceptual adaptation but also involves higher-level cognitive processing, whereas response serial dependence reflects more than mechanical decision inertia, involving the integration of response strategies across trials.关键词
