摘要
采用选择性记忆任务,通过价值顺序2(价值在前、价值在后)×价值高低3(低、中、高)的被试内实验设计考察价值导向元记忆的价值顺序效应。结果发现:(1)空间维度上,价值顺序在前时被试的价值导向元记忆与价值在后无显著差异(实验1);(2)时间维度上,价值顺序优先时被试价值导向元记忆水平显著高于价值随后呈现,并且价值顺序对不同学习阶段价值导向元记忆有显著影响,出现价值顺序效应(实验2)。研究结果为探讨价值顺序对元记忆的影响提供了实证依据,对教学实践有参考价值。
Value-directed metamemory allows individuals to choose more important information to encode, preserve and retrieve in order to allocate their attention resources reasonably and maximize their effective memory performance when they are exposed to some information with different value. Previous research has mainly focused on the differences in value-directed metamomery between young and old people, as well as the impairment of value-directed metamemory in Alzheimer＇s disease and Attention-deficit/hyperactivity disorder. However, there is little research concerning the factors affecting the level of value-directed metamomery.Value-directed metamemory improves memory efficacy by emphasizing high-value information. Therefore, it is of great importance to explore the factors promoting the Value-directed metamemory, such as the influence of value sequence on Value-directed metamemory. Value sequence refers to the Spatial or temporal sequence of value and words. In the present study, two experiments using a selectivity task were conducted to investigate the effect of value sequence on Value-directed metamemory, namely whether there was a value-sequence effect： one was to measure the memory capacity （mean number of words recalled）, the other the memory efficiency/selectivity （the recall of high-value items relative to low-value items is the selectivity index, or SI）. Subjects were told that they would be presented with six different lists of words, and that each list contained 12 words. They were informed that each word was paired with a number, and that this number indicated how much the word was ＂worth.＂ They were told that the values ranged from 1 to 12. Their tasks were to study and recall high-value words as many as possible in order to maximize their score in the experiment. Two experiments were conducted with 2 （value sequence： value-item/item-value） ~ 3 （value category： high-value/medium-value/low-value） within-subject factorial design. Experiment 1 explored that whether there was a va
