Advisor Oh, it looks like we've got that covered Student So I am starting with an article about the physics department. I guess I'd better get to work. Do you have any advice on how I should cover the story? Advisor Well, Max will want to talk to you but I am sure he will tell you to find out things like why the physics departments worried about enrollment. Has the number of students been getting smaller in recent years? By how much? What kinds of plans are they considering to address this problem? [email protected] Student Right, some of those issues are already in what I proposed. Advisor And you'll want to do some interviews, you know, what do the professors think of the plans, what do the students think you get the idea but … Student But wait till I talk to Max before proceeding. Advisor Right, he'll cover everything you need to know to be a report e r for us. Can you come back this afternoon? He will be here until 5 o’clock.

Professor For decades, psychologists have been looking at our ability to perform tasks while other things are going on, how we are able to keep from being distracted and what the conditions for good concentration are. As long ago as 1982, researchers came up with something called the CFQ - the Cognitive Failures Questionnaire. This questionnaire asks people to rate themselves according to how often they get distracted in different situations, like hum … forgetting to save a computer file because they had something else on their mind or missing a speed limit sign on the road. John? John I've lost my share of computer files, but not because I'm easily distracted. I just forget to save them. Professor And that's part of the problem with the CFQ. It doesn’t take other factors into account enough, like forgetfulness. Plus you really can’t say you are getting objective scientific results from a subjective questionnaire where people report on themselves. So it’s no surprise that someone attempted to design an objective way to measure distraction. It’s a simple computer game designed by a psychologist named, Nilli Lavie. In Lavie’s game, people watch as the letters N and X appear and disappear in a certain area on the computer screen. Every time they see an N, they press one key, and every time they see an X they press another, except other letters also start appearing in the surrounding area of the screen with increasing frequency which creates a distraction and makes the task more difficult. Lavie observed that people’s reaction time slowed as these distractions increased. [email protected] Student 2 Well that’s not too surprising, isn’t it?
