Abstract

This study measured mu rhythm desynchronization (MRD), while nine-month-old infants observed an agent extend her arm and hand, palm up ('back-of-hand action') either in social (object and recipient present), individual (object present, recipient absent), or social object-absent (recipient present, object absent) situations across two experiments. In addition, infants' MRD was measured as they reached for objects. Results revealed significant mu desynchronization in the right centro-parietal region selectively for the social group, indicating that infants processed the back-of-hand action as an object-directed request. Findings suggest to extend the action reconstruction account to object-directed communicative actions as well.

镜像交际行为:9个月大婴儿“手背”动作对Mu节奏不同步反应的语境调节

这项研究测量了mu节律不同步(MRD)，而9个月大的婴儿在两个实验中观察到，在社会(物体和接受者在场)、个人(物体在场，接受者缺席)或社会物体缺席(接受者在场，物体缺席)的情况下，被试者伸出手臂和手，手掌向上(“手背动作”)。此外，婴儿的MRD是在他们伸手拿东西时测量的。结果显示，在社会群体中，右侧中央-顶叶区域选择性地出现了显著的mu非同步，表明婴儿将手背动作处理为对象导向的请求。研究结果建议将行为重构理论扩展到对象导向的交际行为。

期刊介绍： Devoted to exploring relationships between brain and behavior across the life span, Developmental Neuropsychology publishes scholarly papers on the appearance and development of behavioral functions, such as language, perception, and social, motivational and cognitive processes as they relate to brain functions and structures. Appropriate subjects include studies of changes in cognitive function—brain structure relationships across a time period, early cognitive behaviors in normal and brain-damaged children, plasticity and recovery of function after early brain damage, the development of complex cognitive and motor skills, and specific and nonspecific disturbances, such as learning disabilities, mental retardation, schizophrenia, stuttering, and developmental aphasia. In the gerontologic areas, relevant subjects include neuropsychological analyses of normal age-related changes in brain and behavioral functions, such as sensory, motor, cognitive, and adaptive abilities; studies of age-related diseases of the nervous system; and recovery of function in later life. Empirical studies, research reviews, case reports, critical commentaries, and book reviews are featured in each issue. By publishing both basic and clinical studies of the developing and aging brain, the journal encourages additional scholarly work that advances understanding of the field of lifespan developmental neuropsychology.
