特征关联编码对相似声目标学习记忆的影响

Effect of associated encoding of features on similar acoustic target learning and memory

为了考察特征关联编码对相似声目标学习记忆的影响,对两组被试进行了相同任务的学习记忆实验。学习周期为13天,每天学习强度(声目标呈现次数)相同,学习结束后进行了遗忘测量,持续到第16天。对照组未采用任何特殊记忆方法,实验组在学习记忆任务时呈现听觉特征与数序关联编码信息。实验结果表明,实验组被试整体记忆饱和点出现较晚,且容量有显著提高,但记忆遗忘速率较大,不过保持量相对对照组更高。实验证明了听觉特征与数序关联编码能够提供有效的记忆编码信息,提升被试的学习记忆效率。

For investigating the effects of encoding auditory features on the learni,~g and memory of similar acoustic targets, two groups of subjects were tested with the same task.Two groups were studied for 13 days, the daily learning intensity （the number of acoustic target presentation） was the same.After the end of the study, taking 6 times fnrgotten measures, lasted 16 days.The control group did not use any special memory method, the experimental group in the learning and memory tasks presented information of encoding auditory, features with number sequence.The experimental results show that the experimen- tal group, the overall memory saturation point appears late, and the capacity is significantly improved, the memory forgetting rate is larger, hut the retention is higher than the control group.Resufts indicate that the auditory features associat- ed with number sequence coding can provide memory encoding information effectively, enhance the efficiency of learning and memory.
