Abstract

Changes in word production occur across the lifespan, with adolescence representing a knot point between children's and adults' performance and underlying brain processes. Previous studies on referential word production using picture naming tasks have shown a completely adult-like pattern in 17-year-old adolescents and an intermediate pattern between children and adults in adolescents aged 14-16 years old, suggesting a possible involvement of visuo-conceptual processes in the transition from childhood to adulthood. Given the visual nature of the picture naming task, it is unclear whether changes in visuo-conceptual processes are specifically related to the referential word production or if overall changes in conceptual to lexical processes drive maturation. To answer this question, we turned to an inferential word production task, i.e., naming from auditory definitions, involving different conceptual to lexical processes relative to referential naming. Behavior and electroencephalographic Event-Related Potentials (ERP) in a (visual) referential word production task and an (auditory) inferential word production task were recorded and compared in three groups of adolescents (respectively, aged 10 to 13, 14 to 16, and 17 to 18). Only the youngest group displayed longer production latencies and lower accuracy than the two older groups of adolescents who performed similarly on both tasks. Crucially, ERP waveform analysis and topographic pattern analysis revealed significant intergroup differences on both tasks. Changes across ages are not merely linked to the visual-conceptual processes of a picture naming task but are rather related to lexical-semantic processes involved in word production.

青少年时期词语生成的变化:参照命名和推理命名的行为和ERP研究。
单词生成的变化贯穿整个生命周期,青春期代表了儿童和成人表现和潜在大脑过程之间的一个结点。先前的研究表明,17岁的青少年使用图片命名的指代词生成模式完全类似成人,14-16岁的青少年使用介于儿童和成人之间的模式,这表明从童年到成年的过渡可能涉及视觉概念过程。鉴于图片命名任务的视觉性质,尚不清楚视觉-概念过程的变化是否与参考词的产生具体相关,还是概念到词汇过程的整体变化推动了成熟。为了回答这个问题,我们转向了一个推理的单词生成任务,即从听觉定义命名,涉及相对于参考命名的不同概念和词汇过程。对3组青少年(分别为10 ~ 13岁、14 ~ 16岁和17 ~ 18岁)在(视觉)参照词生成任务和(听觉)推理词生成任务中的行为和脑电图事件相关电位(ERP)进行了记录和比较。只有最年轻的一组表现出较长的生产延迟和较低的准确性,而两组年龄较大的青少年在两项任务中表现相似。重要的是,ERP波形分析和地形模式分析显示两项任务的组间差异显著。不同年龄的变化不仅与图片命名任务的视觉-概念过程有关,而且与单词生成过程中的词汇-语义过程有关。

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.
