Abstract
Visual attention and memory of 20 children with reading difficulty (Mage = 134 months), 24 chronological (Mage = 138 months) and 19 reading-age controls (Mage = 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.
