Title
Interaction latency of auditory-visual stimulus onset asynchrony (SOA) in humans
Abstract
Functions of multisensory cells in brain have been shown to integrate multisensory cues despite quite long temporal displacements between the unimodal stimuli. Unfortunately, nothing is known whether the temporal gap of multisensory SOA can influence on the interaction latency in humans. This study repeated the classic experiment of Giard and Peronnet’s [J. Cogn. Neuroscience 11:5, 473-490], but visual stimulus onset was earlier 15 ms (experiment 1) and 30 ms (experiment 2) than the auditory stimulus onset. We examined the most robust interaction effect which was observed by them in the right fronto-temporal region. The result showed, in both experiments, the latencies of this integrative component are same, as well as this interaction latency is not influenced by the temporal gap. The probable reason is that the multisensory cells in here later receive converging visual input than receive converging auditory input, or receive afferent connections from multisensory association areas, as well as this integrative component is a downstream consequence of this auditory-visual SOA integration.

这个确实比较贵了!!!
你有废数据怎么办??扔了,还是重新做??

反应时过长或过短的\错误率超过2%的数据都不用,重新做.我一周下来有的时候一个人的数据都做不完

看英文有点累,哪位能否简单说明一下,此实验结果中,事件相关电位(ERP),V:?D:?V+D:?VD?

interesting!
后来有否尝试SOA更长或是更短??

能否科普一下,“multisensory cells in brain ”主要干什么的,是否对(物体)识别比较有意义?

我想多做一些SOA参数的,但实验请被试是要花钱的,做SOA 0和15及30我已经花了近1万5的人民币了.

联合野(但愿中文是这个名字)的皮质细胞多可称为multisensory cells,我个人认为它们对处理"注意"起到非常重要的做用,我正努力地去证明

hehe,我们这边可能要便宜一些,你们大概一个小时多少钱?
我们这边20-30rmb左右

一小时75人民币,但是废数据太多,平均一人次一个参数的实验就得花费约300元人民币
