人们对属于自己的物品比属于他人的物品更容易回忆和再认,即便物品和主体的所有权关联仅仅是暂时的和想象的,这称之为记忆的所有权效应.该效应在非常年幼的幼儿和一些认知缺陷的个体身上也会出现.跨文化研究表明,东方文化的个体和西方文化的个体在该效应的表现上也存在差异.该效应可能是由于对自我相关的项目进行深度语义加工的结果,但其早期阶段可能是因为获得了更多的注意资源分配.自我选择和身体活动的具身化在该效应中起着调节作用.当注视属于自己的项目时,P300等成分波幅明显增强,这为注意在记忆的所有权效应中的作用提供了脑电方面的支持.当被试对分类任务中属于自己的物品进行再认时,会导致内侧前额叶皮质、扣带回皮质、缘上回和顶叶等皮质中线结构的激活.未来研究需要考虑奖赏加工等其他的认知加工在这一效应中的作用,并尝试利用灵长类动物的研究从进化角度对这一现象进行解释.考察认知障碍个体执行该任务时的脑机制,有助于进一步完善本领域的研究.
People are more likely to recall and recognize something belonging to themselves than to belong to others, even if the ownership of the objects and subject matter is only temporary and imaginary, which is called the ownership effect of memory.This effect occurs in very young children And some cognitive deficits also appear in individuals who cross the cultural studies have shown that there are differences in the performance of the individual of the Eastern culture and the individual of the Western culture.The effect may be due to the deep semantic processing of self-related projects But its early stages may be due to the increased attention paid to resource allocation.The role of self-selection and physical activity plays a regulatory role in this effect.When looking at your own project, the amplitude of the P300 and other components is significant Enhanced, which provided EEG support for the role of attention in the ownership of memory effects.When subjects were re-identifying their own items in the classification task, the medial prefrontal cortex, cingulate cortex, margin The activation of the cortical midline structures such as the supraspinal and parietal lobes, etc. Future studies need to consider the role of other cognitive processing such as reward processing in this effect, And try to use primate research to explain this phenomenon from an evolutionary perspective.Examine the brain mechanism of individuals with cognitive impairment to perform this task and help to further improve the research in this field.
