利用近红外光谱技术，我们研究了受试者在给定的文本中搜索目标字符时的大脑活动。视觉刺激包括两种不同的对比：积极和消极。两种刺激都在阴极射线管（CRT：21英寸）上显示30秒。指导受试者观看CRT上的视觉显示。这一显示包括没有意义的文字。当检测到目标字符时，受试者被指示执行三个任务：（1）通过视觉观察来计数目标字符的数量，（2）用他们的左手的拇指和手指小心地和尽可能快地点击按钮，（3）操作移动的电话。
Using NIRS, we investigated brain activity in subjects searching for target characters in given text. Visual stimuli consisted of two different contrasts: positive and negative. Both stimuli were displayed for 30 sec on a cathode-ray tube (CRT: 21 inches). The subjects were instructed to watch a visual display on the CRT. This display included text without meaning. When target characters were detected, subjects were instructed to perform three tasks: (1) count the number of target characters by visual observation, (2) tap a button with the thumb and fingers of their left hand carefully and as fast as possible and (3) operate a mobile phone.
