Gist-based processing has been proposed to account for robust false memories in the converging-associates task. The deep-encoding processes known to enhance verbatim memory also strengthen gist memory and increase distortions of long-term memory (LTM). Recent research has demonstrated that compelling false memory illusions are relatively delay-invariant, also occurring under canonical short-term memory (STM) conditions. To investigate the contributions of gist to false memory at short and long delays, processing depth was manipulated as participants encoded lists of four semantically related words and were probed immediately, following a filled 3- to 4-s retention interval, or approximately 20 min later, in a surprise recognition test. In two experiments, the encoding manipulation dissociated STM and LTM on the frequency, but not the phenomenology, of false memory. Deep encoding at STM increases false recognition rates at LTM, but confidence ratings and remember/know judgments are similar across delays and do not differ as a function of processing depth. These results suggest that some shared and some unique processes underlie false memory illusions at short and long delays. 相似文献

教师职业倦怠的情感衰竭、去人性化和个人成就感降低3个维度相对独立但也存在相互影响, 对其发展关系进行研究, 有助于深入理解职业倦怠的发展过程, 尽早识别倦怠症状。本研究对3837名小学教师进行追踪测试, 测试间隔为3年, 采用结构方程模型和交叉滞后网络分析模型进行分析, 结果发现小学教师职业倦怠维度最优发展模型为“T1的情感衰竭和个人成就感降低分别预测T2的情感衰竭和个人成就感降低, T1的去人性化预测T2的去人性化和个人成就感降低”, 且最优发展模型具有性别间的一致性和教龄段之间的一致性。这一结果支持并强调了去人性化在小学教师职业倦怠发展中的重要作用, 对识别教师职业倦怠早期症状并采取相应措施有效阻断教师职业倦怠的进一步发展具有一定的理论和现实意义。 相似文献

有氧运动是氧气充足时运用大型肌肉群进行有节奏的持续运动。有氧运动可以加快工作记忆任务中的反应速度;在记忆编码前和记忆巩固阶段进行高强度有氧运动有助于提升情景记忆;高强度有氧运动可以促进内隐记忆。有氧运动可以促进神经营养因子的产生,引起长时程增强,激活海马等与记忆相关的脑区并促进神经元再生。未来可探究有氧运动开始和持续时间的影响、有氧运动强度和认知参与的影响、有氧运动对不同年龄性别群体的影响以及脑源性神经营养因子的中介作用,从而深入揭示有氧运动对记忆的影响及其神经生物学机制。 相似文献
