Musical training refines audiovisual integration but does not influence temporal recalibration

This dataset is the output of an experiment comparing how musicians and non-musicians perceive timing between basic flash-tone stimuli. On each trial in the experiment, a flash and tone with a delay in their onset (stimulus onset asynchrony; SOA) is presented, and participants must indicate whether they perceived the flash and the tone to be presented simultaneously or not. The pattern of audiovisual asynchrony on trials in the past has also been found to affect perception of the current trial (temporal recalibration), so we also tested simultaneity perception after adaptation phases where participants were shown many flash-tone stimuli that had a constant asynchrony.

For each phase in the experiment, the dataset has two columns: an SOA column representing the stimulus condition, and a response column representing whether simultaneity (1) or asynchrony (0) was perceived. Base refers to a baseline stimultaneity judgement phase before adaptation, Test refers to a simultaneity judgement phase after adaptation, Pos represents the fact that the adaptation phase had a positive asynchrony (meaning the tone was delayed by 200 ms), and Neg represents the fact that the adaptation phase had a negative asynchrony (meaning the flash was delayed by 200 ms). For the participant column, M refers to a musician and N refers to a non-musicians. Finally, we have a column Sign Trial which represents the sign (positive or negative) of the SOA on the previous trial (and we calculate this for all trials in the experiment).

本数据集源于一项实验，旨在比较音乐家与非音乐家对于基本闪光与音调刺激之间的时序感知差异。在实验的每一轮测试中，参与者将接收到一个带有启动延迟（刺激启动时间间隔；SOA）的闪光与音调组合，并需判断二者是否为同时呈现。过去试验中音频视觉异步模式的出现亦被发现影响了对当前试验的感知（时序重新校准），因此，我们还测试了在参与者被展示大量具有恒定异步性的闪光与音调刺激后的同时性感知。在实验的每一阶段，数据集包含两列：SOA列表示刺激条件，响应列表示参与者是否感知到同时性（1）或异步性（0）。其中，Base指代适应前的基线同时性判断阶段，Test指代适应后的同时性判断阶段，Pos表示适应阶段存在正向异步性（即音调延迟200毫秒），而Neg则表示适应阶段存在负向异步性（即闪光延迟200毫秒）。在参与者列中，M代表音乐家，N代表非音乐家。最后，Sign Trial列表示前一轮试验中SOA的正负符号（此计算适用于实验中的所有试验）。
