An example of multitasking is taking phone calls while typing an email and reading a book. Studies have shown that it is impossible to switch on your brain pdf free download on more than one task at a time.

However, if one is proficient at one of the tasks at hand, then it is possible to do these tasks. The term has since been applied to human tasks. Since the 1960s, psychologists have conducted experiments on the nature and limits of human multitasking. Here, people are asked to make separate responses to each of two stimuli presented close together in time. An extremely general finding is a slowing in responses to the second-appearing stimulus. Many researchers believe that the cognitive function subject to the most severe form of bottlenecking is the planning of actions and retrieval of information from memory. On the other hand, there is good evidence that people can monitor many perceptual streams at the same time, and carry out perceptual and motor functions at the same time.

Others have researched multitasking in specific domains, such as learning. Junco and Cotten examined how multitasking affects academic success and found that students who engaged in high levels of multitasking reported significant issues with their academic work. A more recent study on the effects of multitasking on academic performance found that using Facebook and text messaging while studying were negatively related to student grades, while online searching and emailing were not. Because the brain cannot fully focus when multitasking, people take longer to complete tasks and are predisposed to error.

A study by Meyer and David Kieras found that in the interim between each exchange, the brain makes no progress whatsoever. Therefore, multitasking people not only perform each task less suitably, but lose time in the process. Brodmann Area 10, a part of the brain’s frontal lobes, is important for establishing and attaining long-term goals. Focusing on multiple dissimilar tasks at once forces the brain to process all activity in its anterior. Though the brain is complex and can perform a myriad of tasks, it cannot multitask well. The brain must then decide which activity is most important, thereby taking more time. These viewpoints differ in that while bottlenecking attempts to force many thoughts through the brain at once, adaptive executive control prioritizes tasks to maintain a semblance of order.

The brain better understands this order and, as psychologists such as Dr. Meyer believe, can, therefore, be trained to multitask. It is not known exactly how the brain processes input and reacts to overstimulation. Some research suggests that the human brain can be trained to multitask.
