ABSTRACT Surprisingly occurring sounds outside the focus of attention can involuntarily capture attention. This study focuses on the impact of deviant sounds on the pupil size as a marker of auditory involuntary attention in infants. We presented an oddball paradigm including four types of deviant sounds within a sequence of repeated standard sounds to 14‐month‐old infants and to adults. Environmental and noise deviant sounds elicited a strong pupil dilation response (PDR) in both age groups. In contrast, moderate frequency deviants elicited a significant PDR in adults only. Moreover, a principal component analysis revealed two components underlying the PDR. Component scores differ, depending on deviant types, between age groups. Results indicate age effects of parasympathetic inhibition and sympathetic activation of the pupil size caused by deviant sounds with a high arousing potential. Results demonstrate that the PDR is a sensitive tool for the investigation of involuntary attention to sounds in preverbal children. © 2015 Wiley Periodicals, Inc . Dev Psychobiol 58: 382–392, 2016.

Developmental Psychobiology

DEVELOPMENTAL PSYCHOBIOLOGY 是一份同行评审期刊，发表来自心理学、生物学、神经科学和医学学科的原创研究论文，有助于理解行为发展。侧重于胚胎/胎儿、新生儿、幼年或成年动物发育的研究以及将行为发育与解剖学、生理学、生物化学、遗传学或进化相关联的多学科研究是合适的。该杂志通过发表对无脊椎动物、鱼类、鸟类、人类和其他动物的研究，代表了关于行为发展的广泛系统发育观点。该杂志发表无论是在实验室还是在现场进行的实验和描述性研究。该杂志还发表评论文章和理论论文，这些文章做出了重要的概念贡献。发展心理生物学的特别专刊，包括关于普遍感兴趣的主题的受邀论文，可以与主编安排。发展心理生物学还出版致编辑的信函，讨论普遍感兴趣的问题或发表在期刊上的材料.讨论已发表材料的信件可能会纠正错误、提供澄清或提供不同的观点。作者应就这些文稿的准备工作咨询编辑。

Developmental Psychobiology is a peer-reviewed journal that publishes original research papers from the fields of psychology, biology, neuroscience, and medicine, contributing to the understanding of behavioral development. The journal focuses on research related to the development of embryos, fetuses, neonates, juveniles, and adult animals, as well as multidisciplinary studies that link behavioral development with anatomy, physiology, biochemistry, genetics, or evolution. By publishing research on invertebrates, fish, birds, humans, and other animals, the journal represents a broad phylogenetic perspective on behavioral development. It accepts experimental and descriptive studies conducted both in laboratories and in the field, and also welcomes commentaries and theoretical papers that make significant conceptual contributions. Special issues on developmental psychobiology, including invited papers on topics of general interest, can be arranged with the editor-in-chief. Additionally, Developmental Psychobiology publishes letters to the editor that discuss issues of general interest or provide feedback on materials published in the journal. These letters may correct errors, offer clarifications, or present alternative viewpoints, and authors should consult the editor regarding the preparation of these manuscripts.
