Task Switching

Decent Essays

The Cost of Task Switching Humans are not like any other living species. Their cognitive ability allows them to preform both simple tasks and complex tasks. It is assumed that people carry out cognitive and motor tasks by tapping into their task-sets. Task-set is the cognitive process the brain takes to perform the task. Every time a person multitasks in order to get more stuff done faster they are experiencing task switching. For example, a student could be typing notes during the lecture and has to type and listen to the professor at the same time. Typing the lecture most probably will take longer since the student has to listen to the professor at the same time. From running a marathon to solving complex mathematical equations the brain …show more content…

Another example of a task switching would be when an Olympian medalist has a 400 meter sprint and then has to perform 20 jumping jacks the brain has to quickly stop one motor act and start a new one. For us it might seem flawless but for an Olympian in a race every millisecond counts and that delay tends to raise one’s reaction cost. This particular experiment tests if there is a significant difference in reaction time between task-switch and task-repeat. In other words, when one changes from doing one cognitive task to another does the brain “shift gears” and would the second task will be negatively affected. In other words, will there be a task switching cost. This may happen since the brain has to stop what it is doing and concentrate on a new cognitive and/or motor task. This is called the “task set reconfiguration (Monsell, 2003)”, and causes a delay in one’s reaction time which ultimately effects their performance on that task. Research has shown (Monsell, 2003) that switching between multiple task tend to raise one’s reaction cost. This experiment recorded the error rate of task-switching versus task-repeat. This allowed us to prove that there is a significant difference between them and support the hypothesis of “task set
