Rosenblum, Miller, and Sanchez (Psychological Science, 18, 392-396, 2007) found that subjects first trained to lip-read a particular talker were then better able to perceive the auditory speech of that same talker, as compared with that of a novel talker. This suggests that the talker experience a perceiver gains in one sensory modality can be transferred to another modality to make that speech easier to perceive. An experiment was conducted to examine whether this cross-sensory transfer of talker experience could occur (1) from auditory to lip-read speech, (2) with subjects not screened for adequate lipreading skill, (3) when both a familiar and an unfamiliar talker are presented during lipreading, and (4) for both old (presentation set) and new words. Subjects were first asked to identify a set of words from a talker. They were then asked to perform a lipreading task from two faces, one of which was of the same talker they heard in the first phase of the experiment. Results revealed that subjects who lip-read from the same talker they had heard performed better than those who lip-read a different talker, regardless of whether the words were old or new. These results add further evidence that learning of amodal talker information can facilitate speech perception across modalities and also suggest that this information is not restricted to previously heard words.
罗森布卢姆、米勒和桑切斯(《心理科学》,第18卷,第392 - 396页,2007年)发现,与面对新的说话者相比,那些首先接受训练去唇读特定说话者的受试者,随后能更好地感知该说话者的听觉语音。这表明,感知者在一种感官模态中获得的说话者体验可以转移到另一种模态,从而使语音更容易被感知。进行了一项实验,以检验说话者体验的这种跨感官转移是否会发生:(1)从听觉语音到唇读语音;(2)针对未经过唇读技能筛选的受试者;(3)当在唇读过程中同时呈现熟悉和不熟悉的说话者时;(4)对于旧词(呈现集中的词)和新词均如此。首先要求受试者从一个说话者那里识别一组单词。然后要求他们对两张面孔进行唇读任务,其中一张面孔是他们在实验第一阶段听到的同一个说话者的。结果显示,从他们听过的同一个说话者那里进行唇读的受试者比从不同说话者那里进行唇读的受试者表现更好,无论这些单词是旧词还是新词。这些结果进一步证明,对非模态说话者信息的学习可以促进跨模态的语音感知,并且还表明该信息并不局限于之前听过的单词。
