Growing evidence supports the hypothesis that episodic versus semantic memories rely primarily on interhemispheric versus intrahemispheric processing, respectively. For example, a recent study found that individuals with presumed greater interhemispheric interaction were superior in episodic recall but inferior at semantic word fragment completion; however, tests of recognition memory yielded no group differences. Interestingly, recognition memory can be based on either explicitly remembering a stimulus or implicitly knowing that a stimulus had been presented. The current experiments administered recognition memory tests to strongly versus mixed handed participants who judged for each recognised item whether their response was based on remembering (episodic memory) or knowing (semantic memory) (Tulving, 1983). Results indicate that strong versus mixed handers are biased towards basing recognition responses on judgements of knowing versus remembering, respectively. As strong versus mixed handedness is associated with greater versus lesser interhemispheric processing, the results support the original hypothesis.
越来越多的证据支持这样一种假说，即情景记忆与语义记忆分别主要依赖于半球间与半球内加工。例如，最近一项研究发现，假定半球间互动较强的个体在情景回忆方面表现出色，但在语义单词片段完成任务中表现较差；然而，识别记忆测试未发现组间差异。有趣的是，识别记忆既可以基于明确记住一个刺激，也可以基于隐含地知道某个刺激已经呈现。当前实验对强利手与混合利手参与者进行了识别记忆测试，让他们针对每个识别出的项目判断自己的反应是基于记忆（情景记忆）还是知晓（语义记忆）（图尔文，1983）。结果表明，强利手与混合利手分别倾向于将识别反应基于知晓与记忆的判断。由于强利手与混合利手分别与更强与更弱的半球间加工相关，这些结果支持了最初的假说。
