Sumario:BACKGROUND: Low general cognitive ability is a common cause for learning and academic difficulties. The present study was undertaken to objectively investigate the cognitive functioning of children having borderline intelligence using electrophysiological measures. MATERIALS AND METHODS: The study was conducted on children having borderline intelligence (IQ: 70-85). The cognitive functioning of children was assessed using event-related potentials. RESULTS: Significant prolongation of the latency of P200, N200, and P300 with no significant difference in the amplitudes was seen in the children having borderline intelligence as compared to controls. CONCLUSIONS: Brain systems that are important for stimulus discrimination and using cognitive representation to guide cognition and behavior are impaired in children with borderline intelligence.
