表象编码对事件性前瞻记忆的影响

为了考察表象编码对事件性前瞻记忆的影响,以汉字为材料,将60名大学本科生随机分到标准编码组和表象编码组中,每组被试均完成材料相同的三个阶段的实验任务.实验结果表明,表象编码对事件性前瞻记忆具有一定的促进作用.无论是标准编码组还是表象编码组,将意向行为与背景相联系都能够产生高水平的前瞻记忆表现.与标准编码条件相比,表象编码条件下被试对线索词和诱发词的反应时更短.此外,与国外使用英文字词的研究结果相比,以汉字为实验材料,被试对线索词和诱发词的反应时均短于词汇判断任务的平均反应时,并未出现线索干扰和诱发干扰效应.

The Effect of Imagery Encoding on Event-based Prospectivememory

To investigate the effect of imagery encoding on prospective memory,we choose Chinese characters as our materials and put sixty undergraduate students into two groups randomly,that is the standard encoding group and the imagery one.Every subject in both groups should finish an identical three-phase task.The experimental results suggest that imagery encoding has certain beneficial effects on prospective memory.Whether the standard encoding or the imagery encoding,with contextually-linked intentions,leads to high levels of prospective memory performance.Shorter reaction time of cues and lures occurs in the imagery encoding condition compared with the standard one.Moreover,contrasted with the foreign studies using English words as their materials,subjects＇ reaction time of cues and lures is shorter than the mean time of lexical decision task.Thus cue interference and lure interference doesn＇t appear in the Chinese characters＇ atmosphere.
