  • Category and semantic distance modulate the impact of prediction on memory

    Jiaojian Dai, Mingze Sun et al.ARTICLEActa Psychologica Sinica2026

    摘要: 人类经常需要根据当前的情景做出预测, 以指导后续的行为。然而, 目前研究者关于可预测和不可预测的记忆表现孰好孰坏争论不休。在本研究中(实验1:项目再认; 实验2:联结再认), 我们通过类别和语义距离操纵预期, 考察了不同预期程度下的记忆表现。两个实验一致表明, 在学习阶段, 参与者加工符合类别规则的项目时正确率更高, 反应时更短。实验2发现, 语义距离越近, P600 (语义整合的ERP指标)越正。两个实验中, 多变量模式分析表明不同条件下的神经表征存在显著差异。两个实验均发现, 随着类别规则的违反和语义距离的增加, 学习阶段N400 (预测程度的ERP指标)的波幅变得更负, 测验阶段的记忆表现变得更差。此外, 学习阶段的N400和测验阶段的记忆表现呈显著的正相关。这些结果表明, 类别和语义距离通过不同的机制调节预期对记忆的影响:类别通过调节编码负担影响记忆, 而语义距离通过调节语义整合影响记忆。这些发现为解决可预测与不可预测项目在记忆表现上的争论提供了新的视角

  • WSK-V102C Covid-19 vaccine effectiveness against Sars-CoV-2 JN.1 symptomatic infection among adults 60 years and older

    Open AccessLin Tang, Weijun Hu et al.ARTICLEBMC Public Health2025

    Among individuals aged ≥ 60 years, WSK-V102C vaccination provided moderate protection against JN.1 symptomatic infection within 6 months, suggesting that older people can benefit from use of this vaccine

  • Effects of unitization on associative and item recognition

    Zejun Liu, Chunyan GuoARTICLEActa Psychologica Sinica2022

    摘要: 研究旨在探讨整合如何影响联结再认和项目再认及其加工过程。编码阶段要求被试学习复合词和非复合词, 提取阶段完成联结再认和项目再认测验。结果显示, 复合词比非复合词有更好的联结再认表现, 但在项目再认表现上两者之间没有显著的差异。ERP结果显示, 在联结再认上, 复合词诱发显著的FN400效应(与熟悉性加工有关)和LPC效应(与回想加工有关), 非复合词只诱发显著的LPC效应, 且复合词比非复合词有更大的LPC效应。在项目再认上, 复合词比非复合词诱发更大的FN400效应。总而言之, 整合在促进联结再认的同时并不会损害项目再认的表现, 支持了“只有收益”观点

  • Evidence for neural re-use hypothesis from the processing of Chinese emotional words

    Tianyi Sun, Xiaoxiao Hao et al.ARTICLEActa Psychologica Sinica2021

    The two main theoretical views of emotional word processing are conflicting. According to standard psycholinguistics, emotions are elicited within the reading network itself after semantic activation. However, neural reuse theories suggest that emotional words can be directly processed by the brain region that is activated in emotional information processing, similar to how emotional images, smell, and faces are processed. This means that emotion…

  • Prevalence and Correlates of Alexithymia and Its Relationship With Life Events in Chinese Adolescents With Depression During the Covid-19 Pandemic

    Open AccessXixin Wang, Xiaoyue Li et al.ARTICLEFrontiers in Psychiatry2021

    Objectives: The incidence of psychological and behavioral problems and depression among adolescents is increasing year by year, which has become an important public health problem. Alexithymia, as an important susceptible factor of adolescent depression, may continue to develop and strengthen under the stimulation of COVID-19-related stressors. However, no studies have focused on alexithymia in adolescent depression during the pandemic in China. …

  • The bilingual L2 advantage in associative recognition

    Guixiong Liu, Yongping Jia et al.ARTICLEActa Psychologica Sinica2019

    Recent research has indicated that humans exhibit better item recognition when working with their second language (L2) than in their first (L1). Associative and item recognition are based on different retrieval information and retrieval processes, even though they share certain characteristics. In the present study, we investigated whether bilingual associative recognition performance was better in L2 than in L1. We asked participants to complete…

  • Emotional arousal influences remembrance of goal-relevant stimuli

    Xi Jia, Chuanji Gao et al.ARTICLEEmotion2019

    Emotional stimuli rarely occur in isolation; instead, they often cluster with nearby neutral items in time and space. Research suggests that emotional arousal at encoding strengthens memory retention for temporally adjacent goal-relevant neutral stimuli. It is an open question whether these emotion-induced enhancement effects are the same for spatially adjacent stimuli. The present study examined how emotional arousal influenced memory of tempora…

  • The effect of positive and negative signs on the SNARC effect in the magnitude judgment task

    Meng Han, Xinrui MAO et al.ARTICLEActa Psychologica Sinica2017

    摘要: SNARC效应(Spatial-Numerical Association of Response Codes)是指被试对数字做按键反应时, 对于较小的数字, 按左键的速度快于按右键; 对于较大的数字, 按右键的速度快于按左键。本研究以ERP作为测量手段, 采用修正的大小判断任务, 旨在探究数字正负号及其异同对SNARC效应的影响。行为结果发现, 在反应时上, 当目标数字与基线数字正负号相同且基线数字为+5时, 一致条件显著快于不一致条件。ERP结果发现, 当目标数字与基线数字正负号相同时, 无论基线数字为+5还是–5, 在反应选择阶段, 不一致都比一致条件更负且均诱发了P3。当目标数字与基线数字正负号相异时, 若基线数字为+5, 一致比不一致条件在刺激呈现阶段诱发了波幅显著更小的N300; 若基线数字为–5, 一致比不一致条件在反应执行阶段诱发了更正的LPP。无论目标数字与基线数字正负号相同还是相异, 在反应选择阶段, 不一致都比一致条件更负且均诱发了P3, 表明出现了SNAR…

  • Effects of Emotional Picture Cues on Directed Forgetting Using the Item Method

    Yingying Wang, Jiuqing LIANG et al.ARTICLEActa Psychologica Sinica2014

    The ability to intentionally forget emotional irrelevant or unwanted materials is vital for memory function. The item method, which is the one of two main variants of directed forgetting paradigm, is the typical approach to exploring the mechanisms of intentional forgetting in the laboratory. When the item method was used, the predominant explanation of directed forgetting effects emphasizes selective encoding, while evidence supporting inhibitio…

  • Source Memory Under Different Emotional Contexts

    Zhe Hu, Qin Zhang et al.ARTICLEActa Psychologica Sinica2013

    摘要: 使用事件相关电位(ERP)技术和测试来源记忆的多键范式, 探讨不同情绪效价背景下来源提取的认知神经机制。学习阶段, 同时呈现汉字和3种效价情绪图片(重叠); 测验阶段, 只呈现汉字, 要求被试进行四键判断:旧字且背景为中性, 旧字且背景为正性, 旧字且背景为负性, 新字。结果发现:在提取阶段, 刺激呈现后300~500 ms, 3种情绪背景下来源判断正确项目和来源判断错误项目都比新项目诱发了更正的ERPs(即都存在新旧效应), 这一结果反映出刺激呈现后300~500 ms是一个早期的项目提取阶段, 它独立于来源提取。并且, 在中性背景下, 两种新旧效应没有差别; 而在正性和负性背景下, 来源判断正确项目的新旧效应显著大于来源判断错误项目。说明相比于中性背景, 情绪背景下被试可能更早对来源信息产生熟悉感。在500~650 ms, 3种情绪背景下都存在来源判断正确项目的新旧效应, 在来源判断错误项目和新项目之间没有显著差异, 来源正确与来源错误有显著的新旧效应差异, 但二者在头皮分布…

  • Dissociating the Neural Correlates of Item Retrieval and Relational Retrieval in Between-domain Inter-item Associative Memory

    Jiuqing LIANG, Jiu-Qing LIANG et al.ARTICLEActa Psychologica Sinica2013

    摘要: 使用ERPs技术, 探讨跨领域项目间联结记忆中项目提取和关系提取的差异。学习阶段, 系列呈现面孔-事件动词材料, 让被试识记面孔、事件动词以及两者之间的关系; 测验阶段, 要求被试对成对刺激进行“相同”、“重组”或“新”判断。结果发现:提取阶段, 刺激呈现后约200 ms, “相同”、“重组”和“新”3种条件下的ERPs开始出现分离, 存在“相同/新”、“重组/新”和“相同/重组”三类新旧效应。在200~300 ms, “相同/新”和“重组/新”两类新旧效应表现在前额和额区皮层; 在300~500 ms, 这两类新旧效应广泛地分布在从前到后各个脑区皮层; 在500~700 ms, “相同/新”新旧效应出现在额-顶区皮层, 而无“重组/新”新旧效应; 在700~1400 ms, 这两类新旧效应发生在前额和额区皮层; 在上述4个时段, “相同/重组”关系新旧效应都发生在额中-中央-顶区皮层。从这些结果可以推知:跨领域项目间联结再认中, 项目新旧效应和关系新旧效应同时出现, 但是关系提…

  • Common Representations between Working Memory and Long-term Memory

    Zhaomin Liu, Chunyan GuoARTICLEActa Psychologica Sinica2013

    摘要: 工作记忆和长时记忆共享记忆系统的信息表征网络, 关系密切。实验采用事件相关电位技术记录长时记忆信息对工作记忆的长时语义启动和工作记忆对相关长时记忆信息的长时语义启动。结果显示:与新项目相比, 学习项(即长时记忆信息)对工作记忆的目标信息产生了明显的行为启动效应, N2潜伏期、波幅和P3潜伏期也表现出明显的神经启动效应, 即, 学习项比新项目的反应时更短、N2和P3的潜伏期更短、N2更正, 但学习对非记忆项的影响不大; 工作记忆对相关的长时记忆信息也产生了神经启动, 表现在类别比较任务中记忆类信息比其他信息(即, 与工作记忆任务中的信息无关的内容)的N400更正。而且, 这种神经启动也会因刺激重复次数的增多而降低:与新项目相比, 学习项会使与之语义类似信息的N400更负。上述两种长时语义启动的存在及其ERPs的神经启动均为长时记忆和工作记忆使用共同信息表征的观点提供了证据支持。证据还表明, 在工作记忆和长时记忆的相互作用中注意是关键的调节因素

  • The Brain Potential Features of Human Face Recognition during Working Memory

    Tianyi Sun, yuanli XU et al.ARTICLEActa Psychologica Sinica2013

    摘要: 采用事件相关电位(ERPs)技术探索延迟匹配任务范式下面孔识别工作记忆的脑电位特征。实验以面孔图片为刺激, 在校大学生被试完成靶匹配工作记忆任务。 结果发现, 被试识别靶面孔及分心物面孔时均在枕颞区两侧诱发N170, 且靶与分心物的N170振幅在相同电极上都没有显著差异, 在颞区两侧的P7和P8上差异显著; 无论靶面孔还是分心物面孔, 工作记忆的ERPs均产生了P300成分。在分别追踪新靶和熟悉靶的工作记忆任务条件下, 靶与分心物的ERPs波形在250 ms后出现分离, 且靶刺激波幅均比分心物更正, 新靶比熟悉靶更正。熟悉分心物与新分心物之间显示出250~650 ms的前额区旧/新效应, 在晚期的450~650 ms时段, 新工作记忆比旧工作记忆波幅更正。这些结果表明, 面孔识别的N170效应可能反映的是面孔知觉的整体加工, 且N170的右半球优势具体为颞区的右侧优势; 先前的面孔学习会影响工作记忆期间大脑对面孔的识别反应

  • Differences of Emotional Words in Implicit and Explicit Memory Tests

    Yueting Li, Yue-Ting Li et al.ARTICLEActa Psychologica Sinica2010

    摘要: 运用事件相关电位(ERPs)技术, 采用学习-再认范式, 探讨情绪词(积极词和消极词)在内隐和外显记忆测验中的差异。结果发现:在内隐记忆测验中, 消极词的ERP波形比积极词更正; 在450~900 ms时程上存在提取方式的ERP分离, 即在内隐提取过程中, 消极词比积极词的ERP波形更正, 而在外显提取过程中, 二者ERP之间不存在差异。这些结果表明, 在相同编码影响下, 内隐提取对情绪性材料敏感, 而外显提取对情绪性材料不敏感。本实验结果说明刺激的情绪信息影响提取过程, 消极词语义较强的注意攫取能力主要体现在内隐提取阶段

  • The Asymmetric Relationship Between Encoding and Retrieval in Implicit and Explicit Memory

    Ying-Fang MENG, Chunyan Guo et al.ARTICLEActa Psychologica Sinica2009

    摘要: 实验采用“学习-测验”范式, 考察在编码或提取中分别附加的干扰任务对内隐测验或外显测验中获得的ERP新旧效应产生的影响。结果表明, 在内隐测验中, 编码干扰对随后测验中的ERP新旧效应没有产生影响, 而提取干扰却改变了300~500ms新旧效应的脑区位置, 破坏了500~700ms新旧效应; 与之相反, 在外显测验中, 编码干扰破坏了500~700ms新旧效应, 而提取干扰对这一效应没有产生影响, 即编码与提取干扰对内隐或外显测验中的ERP新旧效应都产生了非对称性的影响, 但又存在着差异, 从而为两种记忆在编码与提取加工的关系上存在的分离现象提供了神经生理方面的证据

  • Scopolamine Has Different Influences on Spatial Reference Memory and Spatial Working Memory in Rats

    Ping Yu, Chun-Huan QU et al.ARTICLEActa Psychologica Sinica2009

    摘要: 观察东莨菪碱对空间参考记忆和空间工作记忆的编码、保持和提取过程的作用。应用Morris水迷宫实验测定大鼠的空间参考记忆和空间工作记忆,分别在训练的不同阶段腹腔注射东莨菪碱(1mg/kg)和相同容量的生理盐水,比较各东莨菪碱组和生理盐水组之间游泳潜伏期、路径长度、轨迹和游泳速度的差异。结果发现:与注射生理盐水相比,在训练前和探测实验前注射东莨菪碱的大鼠在探测实验中对目标象限不表现出空间偏爱,说明东莨菪碱干扰参考记忆的信息编码和提取过程;而在训练结束后注射东莨菪碱的大鼠探测实验的结果与生理盐水组相比没有显著差异,说明东莨菪碱对参考记忆的保持过程没有影响。在工作记忆实验中,无论第一次测试前、第一次测试后和第2次测试前注射东莨菪碱,均造成大鼠游泳潜伏期延长,说明东莨菪碱干扰工作记忆的编码、保持和提取过程。研究提示M受体在空间工作记忆和参考记忆中发挥不同作用
