Sensitivity and criterion were studied on an attention task requiring detection of new stimuli for a group of 20 patients with unilateral hemispheric damage restricted to the anterior or posterior areas. Patients performed a simple attention task, in which the presence of a novel stimulus had to be detected against the repetition of the same stimulus repeated. Only the site of the lesion (anterior vs posterior damage) influenced the performance of the task. In fact, frontal patients had both lower capacity to discriminate between signals and nonsignals and lower confidence in their responses.
对一组20名单侧半球损伤局限于前部或后部区域的患者，在一项需要检测新刺激的注意力任务中研究了敏感性和标准。患者执行一项简单的注意力任务，其中必须在重复相同刺激的情况下检测新刺激的存在。只有病变部位（前部损伤与后部损伤）影响任务表现。事实上，额叶损伤的患者在区分信号和非信号方面的能力较低，且对其反应的信心也较低。
