Pilot: Recalibration of visual beat timing driven by lexical stress

This is the DAC for the two pilot studies run for the perceptual learning study. In Exp 1, we tested 10 participants on our audio stimuli. In Exp 2, we combined the audio trials with videos of the speaker making a hand beat. Twenty participants were asked on which part of the word they perceived the hand beat. The data from these two pilot studies show us the ambiguous auditory and visual cues that will be used in the perceptual learning study.

本文件为感知学习研究配套开展的两项预实验的DAC。实验1中，我们针对自研听觉刺激对10名被试开展了测试。实验2中，我们将听觉试次与讲话者做出手部动作节拍的视频进行了结合，共招募20名被试，要求其报告感知到手部动作节拍的单词位置。两项预实验所获数据，明确了后续感知学习研究将使用的模糊听觉与视觉线索。
