Abstract

The ability to leverage visual cues in speech perception - especially in noisy backgrounds - is well established from infancy to adulthood. Yet, the developmental trajectory of audiovisual benefits stays a topic of debate. The inconsistency in findings can be attributed to relatively small sample sizes or tasks that are not appropriate for given age groups. We designed an audiovisual speech perception task that was cognitively and linguistically age-appropriate from preschool to adolescence and recruited a large sample ( N = 161) of children (age 4-15). We found that even the youngest children show reliable speech perception benefits when provided with visual cues and that these benefits are consistent throughout development when auditory and visual signals match. Individual variability is explained by how the child experiences their speech-in-noise performance rather than the quality of the signal itself. This underscores the importance of visual speech for young children who are regularly in noisy environments like classrooms and playgrounds.

视听言语感知的益处从学龄前到青春期都很稳定。
从婴儿期到成年期,利用视觉线索进行语音感知(尤其是在嘈杂的背景下)的能力已得到广泛认可。然而,视听益处的发展轨迹仍是一个争论不休的话题。研究结果不一致的原因可能是样本量相对较小或任务不适合特定年龄组。我们设计了一项视听言语感知任务,该任务在认知和语言方面适合学龄前到青少年的年龄,并招募了大量儿童样本(N = 161)(4-15 岁)。我们发现,即使是最年幼的儿童,在获得视觉线索时也会表现出可靠的语音感知优势,而且当听觉和视觉信号相匹配时,这些优势在整个发育过程中都是一致的。个体差异的原因在于儿童如何体验他们的噪声语音表现,而不是信号本身的质量。这强调了视觉语言对经常处于嘈杂环境(如教室和操场)中的幼儿的重要性。

期刊介绍: Multisensory Research is an interdisciplinary archival journal covering all aspects of multisensory processing including the control of action, cognition and attention. Research using any approach to increase our understanding of multisensory perceptual, behavioural, neural and computational mechanisms is encouraged. Empirical, neurophysiological, psychophysical, brain imaging, clinical, developmental, mathematical and computational analyses are welcome. Research will also be considered covering multisensory applications such as sensory substitution, crossmodal methods for delivering sensory information or multisensory approaches to robotics and engineering. Short communications and technical notes that draw attention to new developments will be included, as will reviews and commentaries on current issues. Special issues dealing with specific topics will be announced from time to time. Multisensory Research is a continuation of Seeing and Perceiving, and of Spatial Vision.
