A stairwell in a certain office building is always congested at 12:00 p. m. and 2:00 p. m. The congestion is so bad that people have been complaining to the building's owner.

b. Encourage people to voluntarily keep off the stairwell during peak times.
c. Charge everyone who uses the stairwell when it is congested the same fee which is high enough to discourage some people from using the stairwell during peak times. People who value the use of the stairs the most will be the ones who use the stairwell at peak times.
d. Hold a lottery to determine who wins the right to use the stairwell at peak times.

Who is better at multi-tasking? in business, employees are often asked to perform a complex task when their atten-tion is divided (i.e., multi-tasking). human factors (may 2014) published a study designed to determine whether video game players are better than non–video game play-ers at multi-tasking. each in a sample of 60 college stu-dents was classified as a video game player or a non-player. participants entered a street crossing simulator and were asked to cross a busy street at an unsigned intersec-tion. the simulator was designed to have cars traveling at various high rates of speed in both directions. during the crossing, the students also performed a memory task as a distraction. two variables were measured for each student: (1) a street crossing performance score (measured out of 100 points) and (2) a memory task score (measured out of 20 points). the researchers found no differences in either the street crossing performance or memory task score of video game players and non-gamers. “these results,” say the researchers, “suggest that action video game players [and non-gamers] are equally susceptible to the costs of dividing attention in a complex task”
