Abstract

Time perception has been known to depend on the temporal frequency of the stimulus. Previously, the effect of temporal frequency modulation was assumed to be monotonically lengthening or shortening. However, this study shows that temporal frequency affects time perception in a non-monotonic and modality-dependent manner. Four experiments investigated the time distortion effects induced by modulation of temporal frequency across auditory and visual modalities. Critically, the temporal frequency was parametrically manipulated across four levels (steady stimulus, 10-, 20-, and 30/40-Hz intermittent auditory/visual stimulus). Experiment 1, 2, and 3 consistently showed that a 10-Hz auditory stimulus was perceived as shorter than a steady auditory stimulus. Meanwhile, as the temporal frequency increased, the perceived duration of the intermittent auditory stimulus was lengthened. A 40-Hz auditory stimulus was perceived as longer than a 10- Hz auditory stimulus, but did not differ significantly from a steady one. Experiment 4 showed that, for the visual modality, a 10-Hz visual stimulus was perceived as longer than a steady stimulus, and the perceived duration was lengthened as temporal frequency increased. This study demonstrated that within the scope of the temporal frequencies examined in this study, there were differential distortion effects observed across sensory modalities.

Pretraining has recently greatly promoted the development of natural language processing (NLP)
We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance

【要点】：本研究发现时间感知受到刺激的时频调制影响，并且这种影响是非单调的，依赖于感觉模态，这与先前认为的时频调制影响是单调的假设不同。

【方法】：研究通过四个实验探讨了听觉和视觉模态下时频调制对时间扭曲效果的影响，通过参数化操纵时频在四个水平（稳态刺激、10-Hz、20-Hz和30/40-Hz间歇性听觉/视觉刺激）。

【实验】：实验1至3一致显示，10-Hz的听觉刺激被感知为比稳态听觉刺激更短，而随着时频增加，间歇性听觉刺激的感知时长延长。40-Hz的听觉刺激被感知为比10-Hz的更长，但与稳态刺激没有显著差异。实验4表明，对于视觉模态，10-Hz的视觉刺激被感知为比稳态刺激更长，且随着时频增加，感知时长也延长。实验使用的数据集名称未在文本中提供，结果为不同感觉模态在考察的时频范围内显示出不同的时间扭曲效果。
