研究了慢性严重耳鸣对两种视觉任务的影响。一般的资源枯竭假说指出，耳鸣组相对于对照组的整体表现会受损，而控制处理假说指出，只有要求高的任务，需要战略过程，受到影响。11名经历了两年多严重耳鸣的参与者组成了耳鸣组。对照组的年龄和语言智商相匹配。焦虑、抑郁和高频平均听力水平作为协变量。任务包括说字（容易）和说颜色（要求）条件的Stroop任务，一个单一的（基线）反应时间（RT）的任务，和双重任务，涉及字阅读或类别命名，同时执行并发RT任务。结果支持一般的资源耗竭假说：耳鸣组的RT在Stroop任务的两种条件下，以及在双任务的单词阅读和类别命名条件下都较慢。差异不归因于高频平均听力水平，焦虑或抑郁。
The effect of chronic, severe tinnitus on two visual tasks was investigated. A general depletion of resources hypothesis states that overall performance would be impaired in a tinnitus group relative to a control group whereas a controlled processing hypothesis states that only tasks that are demanding, requiring strategic processes, are affected. Eleven participants who had experienced severe tinnitus for more than two years comprised the tinnitus group. A control group was matched for age and verbal IQ. Levels of anxiety, depression, and high frequency average hearing level were treated as covariates. Tasks consisted of the say-word (easy) and say-color (demanding) conditions of the Stroop task, a single (baseline) reaction time (RT) task, and dual tasks involving word reading or category naming while performing a concurrent RT task. Results supported the general depletion of resources hypothesis: RT of the tinnitus group was slower in both conditions of the Stroop task, and in the word reading and category naming conditions of the dual task. Differences were not attributable to high frequency average hearing level, anxiety, or depression.
