* you try to predict what comes next, and that’s a cognitive cost Overhearing someone else talking on a cell phone (“halfalogue) Other people’s use of technology can impair your cognitive functioning implications for how we integrate technology into our daily activities like driving while talking on a cell phone or even heads-up displays we also think that “attention” is the same thing as “where we’re looking.” It’s not.Ĭ.
