Multitasking-kyvyillään kehuskelevat todennäköisesti eivät ole lainkaan kykeneviä monen homman hoitamiseen yhtä aikaa. Parhaat multitaskaajat näyttävät olevan sellaisia, jotka eivät lainkaan mielellään multitaskaile vaan keskittyvät yhteen hommaan kerrallaan, koska silloin se tulee paremmin tehdyksi.
We showed that people who multitask the most are those who appear to be the least capable of multitasking effectively.
The key findings:
"The persons who are most capable of multitasking effectively are not the persons who are most likely to engage in multiple tasks simultaneously." Instead, people who score high on a test of actual multitasking ability tend not to multitask because they are better able to focus attention on the task at hand.
The more people multitask by talking on cell phones while driving or by using multiple media at once, the more they lack the actual ability to multitask, and their perceived multitasking ability "was found to be significantly inflated." In fact, 70 percent of participants thought they were above average at multitasking, which is statistically impossible.
People with high levels of impulsivity and sensation-seeking reported more multitasking. However, there was an exception: People who talk on cell phones while driving tend not to be impulsive, indicating that cell phone use is a deliberate choice.
The research suggests that people who engage in multitasking often do so not because they have the ability, but "because they are less able to block out distractions and focus on a singular task."
