Context switching is a major challenge when it comes to multitasking, as it requires the individual to rapidly switch focus from one task to another, often within a very short period of time.
This is a difficult feat, as the person must be able to switch between tasks quickly, while still retaining the information they had previously gathered.
Additionally, the person must be able to quickly adjust to the different processes associated with each task and the differing levels of complexity associated with them.
This often results in a high level of stress for the individual, as they must be able to keep up with the demands of multiple tasks, all of which are competing for their attention.
