摘要

采用对象替代掩蔽法对20例阅读困难儿童(134个月)、24例时间顺序儿童(138个月)和19例阅读年龄对照组(92个月)的视觉注意和记忆进行了检测;掩膜偏移延迟增加视觉注意和视觉短期记忆需求。N1(报警)、N2pc (n2 -后对侧)的ERP振幅差异;选择性注意)和SPCN(持续后对侧阴性;记忆负荷)。按时间顺序控制的效果最好，但ERP的结果好坏参半。N1和N2pc无组间差异。SPCN在阅读困难方面表现出更强的负性，表明记忆负荷和异常抑制更大。

Neural Correlates of Visual Attention and Short-Term Memory in Children with Reading Difficulty.

Visual attention and memory of 20 children with reading difficulty (M_age = 134 months), 24 chronological (M_age = 138 months) and 19 reading-age controls (M_age = 92 months) were examined using object substitution masking; mask offset delay increases visual attention and visual short-term memory demands. ERP amplitude differences in the N1 (alerting), N2pc (N2-posterior-contralateral; selective attention), and SPCN (sustained posterior contralateral negativity; memory load) were expected between groups. Chronological controls performed best, but ERP results were mixed. No group differences were found for N1 or N2pc. SPCN showed enhanced negativity in reading difficulty, indicating greater memory load and anomalous inhibition.

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.
