The current study investigates whether informative, mutually redundant audiovisual cues support better performance in a category learning paradigm. Research suggests that, under some conditions, redundant multisensory cues supports better learning, when compared with unisensory cues. This was examined systematically across two experiments. In Experiment 1, children aged 5, 7, and 10 years were allocated to 1 of the 3 "modality" conditions (audio informative only, visual informative only, and audiovisual informative) and explicitly instructed to learn the category membership of individual exemplars, as determined by a threshold of correct responses. Unisensory or redundant multisensory cues determined category membership, depending on the learning condition. In addition to significant main effects of age group and condition, a significant interaction between age and sensory condition was found, with 5-year-olds performing better when presented with redundant multisensory cues compared to unisensory cues. Ten-year-olds performed better with auditory informative only cues, compared to visual informative only cues, or informative but redundant multisensory cues, with no significant difference between the latter two. In Experiment 2, the multisensory condition was presented to separate groups of 5-, 7-, and 10-year-olds, examining explicit learning outcomes in the audiovisual informative condition. Results showed that children who reached threshold during training were faster, made fewer errors, and performed better during test trials. Learning appeared to be based on the visual informative cues. Findings are discussed in the context of age-related selective attention, suggesting that the value of providing multisensory informative cues to support real-world learning depends on age and instructional context.

当前的研究旨在调查在类别学习范式中,信息丰富且相互冗余的视听线索是否能支持更好的表现。研究表明,在某些条件下,与单感觉线索相比,冗余的多感觉线索支持更好的学习。本研究通过两个实验系统地检验了这一点。在实验 1 中,5 岁、7 岁和 10 岁的儿童被分配到 3 种“模态”条件之一(仅听觉信息、仅视觉信息和视听信息),并被明确指示根据正确响应的阈值来学习个体范例的类别成员身份。单感觉或冗余的多感觉线索取决于学习条件来确定类别成员身份。除了年龄组和条件的显著主效应外,还发现了年龄和感觉条件之间的显著交互作用,与单感觉线索相比,5 岁儿童在呈现冗余多感觉线索时表现更好。与仅听觉信息线索相比,10 岁儿童在仅视觉信息线索或信息丰富但冗余的多感觉线索下表现更好,后两者之间没有显著差异。在实验 2 中,将多感觉条件呈现给单独的 5 岁、7 岁和 10 岁组,检查视听信息丰富条件下的明确学习结果。结果表明,在训练过程中达到阈值的儿童在测试试验中速度更快、错误更少、表现更好。学习似乎基于视觉信息线索。研究结果在与年龄相关的选择性注意的背景下进行了讨论,表明为支持现实世界的学习而提供多感觉信息线索的价值取决于年龄和教学环境。(PsycINFO 数据库记录(c)2019 APA,保留所有权利)。
