摘要

This study emphases to investigate the working memory impairments limitations of normal children's in visual stimuli assessments using Event-related Potentials (ERPs) signal. 97 children aged between 7 to 12 years old were subjected to a two-phase computer based assessment while their working memory activity was concurrently recorded using Electroencephalograph (EEG) 9200 machine at the prefrontal cortex. EEG signals were segmented and averaged into the event of stimulus to obtain the ERPs pattern. In neurophysiology research, ERP component at P300 will forms the visual responsiveness to detect the cognitive processes. P300 component is decomposed using Discrete Wavelet Transform (DWT) with Daubechies (db4) at 7th level decomposition. In conclusion, visual stimuli assessment brings up a dissimilar in P300 pattern between two-phases. The mean performance shows that, the younger children tend to working memory impaired rather than older children.
