目的：本研究的目的是确定在字表学习过程中进行的等长手部测力计收缩所产生的身体唤醒是否会影响年轻人的自由回忆或再认记忆。方法：24名年轻人（12名女性;法师= 22岁）提出了4个20个项目的词汇表。中度觉醒诱导12名成人的初始30秒最大的手测力计挤压力生产的50%最大;低觉醒诱导12名成人的初始1秒最大的测力计挤压力生产的10%最大的学习过程中。在编码，巩固和回忆学习阶段经历的双任务条件下的记忆表现进行了比较，在此期间，在没有等距运动的情况下学习单词的单任务控制条件。结果如下：计划对比显示，唤醒与单词编码一致导致即时回忆显著较差，F（1，23）= 10.13，p <0.05，= 0.31，延迟自由回忆，F（1，23）= 15.81，p <0.05，= 0.41，识别记忆，F（1，23）= 6.07，p <0.05，= 0.21，与没有性唤起时相比。这两种唤醒条件都没有促进参与者的记忆表现。结论：特定于学习的编码阶段的长期记忆表现的减少被解释为对参与者的双任务注意力要求。
Purpose: The purpose of this study was to determine if physical arousal produced by isometric hand-dynamometer contraction performed during word-list learning affects young adults' free recall or recognition memory. Method: Twenty-four young adults (12 female; Mage = 22 years) were presented with 4 20-item word lists. Moderate arousal was induced in 12 adults by an initial 30-s maximal hand-dynamometer squeeze with force productions of 50% maximum; low arousal was induced in 12 adults by an initial 1-s maximal dynamometer squeeze with force production of 10% maximum during learning. Memory performances following dual-task conditions experienced during the encoding, consolidation, and recall phases of learning were compared to a single-task control condition during which words were learned in the absence of isometric exercise. Results: Planned contrasts revealed that arousal coinciding with word encoding led to significantly poorer immediate recall, F(1, 23) = 10.13, p < .05, = .31, delayed free recall, F(1, 23) = 15.81, p < .05, = .41, and recognition memory, F(1, 23) = 6.07, p < .05, = .21, compared with when there was no arousal. Neither arousal condition facilitated participants' memory performance. Conclusion: The reduction in long-term memory performance specific to the encoding phase of learning is explained in terms of the dual-task attentional demands placed on participants.
