Remembering an event typically takes less time than experiencing it, suggesting that episodic memory represents past experience in a temporally compressed way. Little is known, however, about how the continuous flow of real-life events is summarised in memory. Here we investigated the nature and determinants of temporal compression by directly comparing memory contents with the objective timing of events as measured by a wearable camera. We found that episodic memories consist of a succession of moments of prior experience that represent events with varying compression rates, such that the density of retrieved information is modulated by goal processing and perceptual changes. Furthermore, the results showed that temporal compression rates remain relatively stable over one week and increase after a one-month delay, particularly for goal-related events. These data shed new light on temporal compression in episodic memory and suggest that compression rates are adaptively modulated to maintain current goal-relevant information. 相似文献

We developed a new test to examine incidental temporal order memory for a self-generated sequence of tasks one might complete in everyday life. Young and older adults were given 10 cards, each listing a task one might accomplish in a typical day. Participants were asked to self-generate a “to do” list by placing the 10 cards in a sequence representing the order in which they would accomplish the tasks, but were not informed of a subsequent memory test. We assessed immediate free recall, delayed free recall, and delayed cued recall for the order of the tasks in the sequence. Older adults were significantly impaired relative to young adults on immediate free recall, delayed free recall, and delayed cued recall. Correlation analyses with standardized neuropsychological tests provide preliminary evidence for construct validity for our test, which is portable and can be rapidly administered in clinical or laboratory settings. 相似文献

The way people envision their future (self-prospection) plays a key role in the energization required to pursue desired goals. We proposed that energization is determined by time distance from the imagined future-self and the individual’s consideration of future consequences (CFC). We hypothesized that, when imagining their distant (vs. near) future-self, individuals higher on CFC (i.e., those who construe a stronger link between present and future selves), would report greater energization. Participants completed the CFC scale, imagined their distant or near future-self, and reported their energy level. Imagining distant (vs. near) future-self fostered energy among participants higher on CFC (Experiments 1–2), an effect mediated by vividness of self-representations (Experiment 2). Self-prospection has implications for current states, and specifically for felt energy. 相似文献

绿色消费虽然受到越来越多的关注,但消费者的绿色承诺很难转化为实际的购买行为,出现了消费者的不作为现象。本研究试图探讨时间参照对消费者不作为的影响以及环保意识是否能够有效抑制这种不作为。研究发现,消费者在近期情境下对绿色产品的购买意愿低于远期,出现了绿色消费不作为现象,即个体更倾向于在将来而不是现在购买绿色产品。尤为重要的是,环保意识对消费者不作为的弱化作用受制于个体的产品环境怀疑:产品坏境怀疑较低时环保意识的弱化作用明显,而产品环境怀疑较高时环保意识的弱化作用则不存在。 相似文献

准确识别言语中的情绪韵律信息对社会交往非常重要。本研究采用功能近红外成像技术, 探索外显和内隐情绪加工条件下愤怒、恐惧、快乐三种情绪韵律加工过程中的大脑皮层神经活动。结果表明, 对愤怒、恐惧、快乐韵律进行特异性加工的脑区分别为左侧额极/眶额叶、右侧缘上回、左侧额下回, 其中右侧缘上回脑区同时受到情绪和任务的调控。此外, 右侧颞中回、颞下回和颞极在情绪外显任务中的激活明显强于内隐任务。本研究的结果部分支持了情绪韵律的层次模型, 也对该模型的第三层次, 即“额区对语音情绪信息的精细加工需要外显性情绪加工任务参与”提出了质疑。 相似文献
