The study ran 310 undergraduate psychology students through a battery of tests and questionnaires to measure actual multitasking ability, perceived multitasking ability, cell phone use while driving, use of a wide array of electronic media, and personality traits such as impulsivity and sensation-seeking.
-
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
-
70 percent of participants thought they were above average at multitasking, which is statistically impossible
-
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
-
People with high levels of impulsivity and sensation-seeking reported more multitasking
-
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 study participants were 310 University of Utah psychology undergraduates – 176 female and 134 male with a median age of 21 – who volunteered for their department's subject pool in exchange for extra course credit.

To measure actual multitasking ability, participants performed a test named Operation Span, or OSPAN.
-
The test involves two tasks: memorization and math computation
-
Participants must remember two to seven letters, each separated by a math equation that they must identify as true or false
-
A simple example of a question: "is 2+4=6?, g, is 3-2=2?, a, is 4x3=12." Answer: true, g, false, a, true.
-
Participants also ranked their perceptions of their own multitasking ability by giving themselves a score ranging from zero to 100, with 50 percent meaning average.
-
Study subjects reported how often they used a cell phone while driving, and what percentage of the time they are on the phone while driving
-
also completed a survey of how often and for how many hours they use which media, including printed material, television and video, computer video, music, nonmusic audio, video games, phone, instant and text messaging, e-mail, the Web and other computer software such as word processing
-
researchers looked for significant correlations among results of the various tests and questionnaires
-
people who multitask the most tend to be impulsive, sensation-seeking, overconfident of their multitasking abilities, and they tend to be less capable of multitasking
-
25 percent of the people who performed best on the OSPAN test of multitasking ability "are the people who are least likely to multitask and are most likely to do one thing at a time
-

-
Media multitasking – except cell phone use while driving – correlated significantly with impulsivity, particularly the inability to concentrate and acting without thinking.
