The investigation of semantic memory deficit in chronic tinnitus: a behavioral report

Abstract Introduction: Tinnitus is a central auditory disorder in which different processing systems are involved as a network. One of these networks is memory. Previous studies have demonstrated some deficits in various types of memory in chronic tinnitus. Objectives: The main purpose of the present study was to investigate the semantic memory, which is not yet investigated in the tinnitus population. Methods: In this case-control study, 15 subjects with chronic tinnitus and 16 matched healthy controls were included. 40 semantically related and 40 semantically unrelated word pairs were presented to the participants in a counter-balanced fashion. They were asked to make decision about their semantic relatedness. Then the participants’ reaction times and the accuracy of responses were calculated. Results: Mean of reaction times were significantly longer in the tinnitus group (M = 1034 ms, SD = 0.31) compared to the control group (Mean = 1016 ms, SD = 0.13), p

引言与研究背景：耳鸣（tinnitus）是一种中枢听觉障碍，其发生涉及多个构成网络的加工系统，其中之一便是记忆系统。既往研究已证实慢性耳鸣患者存在多种类型的记忆功能缺损。
研究目的：本研究的核心目的在于探究语义记忆（semantic memory）在耳鸣人群中的表现，而此前尚未有针对该群体的相关研究。
研究方法：本研究为病例对照研究（case-control study），共纳入15名慢性耳鸣患者与16名匹配的健康对照者。以平衡呈现的方式向受试者展示40对语义相关词对与40对语义无关词对，要求受试者判断词对的语义关联性，并记录其反应时与反应正确率。
研究结果：耳鸣组的平均反应时（M=1034 ms，SD=0.31）显著长于对照组（M=1016 ms，SD=0.13），p
