Document Summary
Dual task: the concurrent performance of 2 tasks that can be performed independently and have distinct goals. Multiple resource theory: people have a limited set of resources available for mental processes if you dedicate your attention to 1 stimuli, it will get 100% of your attentional resources. The regions of the brain involved in attentional processing: Dorsolateral prefrontal cortex responsible for most of our attentional processes and working memory. Primary motor cortex involved in the execution in the information processing model. The regions of the brain do not work independently. Bottleneck theory: although there are many inputs, we cannot process them all (because we have a limited amount of attentional resources), therefore, we have to decide what we pay attention to and what we ignore. We never actually do tasks at the exact same time. Examples: listening and taking notes, texting and driving, driving. Ef ciency is affected by: task complexity (unfamiliar to familiar, task similarity, skill/practice.
