Divided attention impairments after traumatic brain injury
This research investigated whether people with severe traumatic brain injury(TBI) are impaired on divided attention tasks requiring working memory. Inexperiment 1, a severe TBI and control group performed two tasks requiringworking memory separately and concurrently. Results showed that the TBI grouphad impaired divided attention when performing the two tasks concurrently,although the two groups did not differ in performance when these tasks wereperformed separately. Experiment 2 showed that performance on the paced auditoryserial addition task improved with increases in the intertrial interval for bothTBI and control groups. A meta-analysis showed that TBIs are impaired on dividedattention when the tasks require controlled processing, but not when the taskscan be carried out relatively automatically.Publication Types: Meta-Analysis
