The effect of video games on visual attention A-B Task In this experiment, a series of black letters will be displayed on a gray background one after another very quickly in the center of the screen. One of the letters will be white. In each trial, you have two tasks. First, you must notice and remember which letter was white. In some trials, one of the letters displayed after the white letter will be an 'X'. This is the only place an 'X' can ever occur. Your second task is to notice whether or not an 'X' was presented. At the end of the trial, you respond by pressing the key of the white letter, and then by pressing either "Y" (yes) or "N" (no) to indicate whether an 'X' was presented. |
