Sanbonmatsu and his colleagues gave the students a set of tests and asked them to report how often they multitasked，how good they thought they were at it，and how sensation-seeking (寻求刺激) or impulsive (冲动) they were.They then evaluated the participants’multitasking ability with a tricky mental task that required the students to do simple mathematical calculations while remembering a set of letters. Not surprisingly，the sci
