An Investigation of the Neural Correlates of Attention and Effector Switching Using ERPs
Event-related brain potentials (ERPs) were used to examine the neural correlates of attention and effector switching when one or both types of switches were performed on a given trial. The response time data revealed that switch costs tended to increase from attention switches to effector switches to attention+effector switches. For right-hand responses, attention switching was associated with a parietal slow wave and effector switching was associated with a central readiness potential. For left-hand responses, attention switching was associated with a parietal slow wave, and effector switching was associated with a parietal slow wave and a readiness potential. These data suggest that the independence of the neural systems supporting attention and effector switching may be limited to instances where the dominant hemisphere controls the response.
