Even though we gave no instruction to participants to switch between these two tasks, we see that is actually what is happening in their brain. They do not maintain the memory network at the same level when the selective attention network is engaged. Rather, they dynamically switch between these two cognitive control networks. The results of our study are consistent with many other studies that have shown when we simultaneously pursue multiple goals that compete for cognitive control resources, our brains switch between tasks—they do not parallel process.35 So, while the behavioral goals may
