多感觉整合中的声音诱发闪光错觉效应

声音诱发闪光错觉效应是典型的视听整合错觉现象, 是指当视觉闪光刺激与间隔100 ms内的听觉声音刺激不等数量呈现时, 被试知觉视觉闪光的数量与听觉声音的数量相等。声音诱发闪光错觉的影响因素既包括自下而上和自上而下的被试内差异因素, 也包括视听刺激依赖程度、视听整合的发展和视听刺激知觉敏感性等被试间差异因素。该效应的产生在时程上主要体现在早期加工阶段, 在脑区上主要涉及多处皮层及皮层下相关脑区。未来研究应进一步考察注意、奖赏和视听整合方式等认知加工对声音诱发闪光错觉的影响, 同时也应该关注声音诱发闪光错觉对记忆和学习的影响以及结合计算模型和神经科学的手段进一步探讨其认知神经机制。     

污名化对被污名个体人际互动的影响

污名是指个体所具有不受欢迎的特征, 这种特征会导致个体在一定社会背景下被主流文化群体贴负性标签、贬低、侮辱而遭受到污名化。污名化对个体或群体本身会有消极影响, 不仅会使个体遭受到来自他人的歧视、排斥或拒绝等这些直接作用于自身的外部影响, 还会进一步消极影响被污名个体在人际互动中的表现和行为反应。被污名个体与主流文化群体之间的消极互动又会进一步加剧主流文化对被污名个体或群体的排斥, 形成恶性循环。从被污名个体的角度出发, 有助于更加深入地探讨污名化对被污名个体人际互动方面的影响以及被污名个体采取的应对方式。     

父母学业参与和高中生消极情绪的关系：亲子关系的中介作用以及父母心理控制的调节作用

目的：本研究旨在探究父母学业参与和学生消极情绪的关系及作用机制。方法：本研究对1569名上海高中生进行问卷调查,学生填写学业参与量表、心理控制量表、亲子关系量表和消极情绪评估量表。结果：（1）父母学业参与和学生的消极情绪负相关;（2）父母学业参与可通过提高亲子关系质量从而减少学生的消极情绪;（3）父母心理控制调节父母学业参与和亲子关系质量、父母学业参与和消极情绪之间的关系。结论：父母积极参与子女学业并减少对子女的心理控制,将更有利于形成良好的亲子关系和减少消极情绪。     

Does Scope of Attention Affect Creativity? Testing the Attentional Priming Hypothesis

Creativity is linked to broad scope of attention, a state or trait that allocates attentional resources over a wide range of perceptual stimuli. According to the attentional priming hypothesis, a mechanism underlying the creativity–attention link is that broad perceptual attention scope primes broad conceptual attention scope—the activation of a wide range of memory contents—which therefore facilitates creative ideation. This study aimed to test the hypothesis in three experiments using three manipulations and two creativity tasks. Experiment 1 used the Navon letter task to prime attention to global patterns or local details of composite stimuli and measured creativity via the task to generate alternative uses of daily objects. Experiment 2 modified a cue-size procedure in which participants repeatedly attended to large or small visual cues before a target stimulus appeared. Experiment 3 devised a manipulation that required participants to view and visualize images associated with broad or narrow attention and adopted the alternative uses task and the task to invent alien creatures. Across the experiments, although the results were in the predicted direction, they were non-significant. This study found no evidence that broadness of perceptual attention affects creativity.     

父母元情绪理念与青少年问题行为:迷走神经的调节作用

探讨父母元情绪理念与青少年问题行为的关系以及青少年自身迷走神经功能对两者关系的影响。采用“心算任务范式”及问卷法, 对224名青少年及其父母进行测量与调查。结果发现:(1) 母亲情绪教导理念负向预测青少年内外化问题行为, 母亲情绪失控理念正向预测青少年内外化问题行为, 母亲情绪不干涉理念正向预测青少年外化问题行为; 父亲情绪教导理念负向预测青少年内化问题行为, 父亲情绪失控理念正向预测青少年外化问题行为。(2) 当青少年迷走张力较低时, 母亲情绪不干涉理念正向预测青少年外化问题行为; 当青少年迷走抑制较低时, 母亲情绪失控理念正向预测青少年内化、外化问题行为, 父亲情绪失控理念正向预测青少年外化问题行为。综上, 父母元情绪理念能够预测青少年问题行为, 且父母元情绪理念对青少年问题行为影响存在差异。同时, 迷走神经功能对父母元情绪理念与青少年问题行为的关系具有一定调节作用。     

老年人声音诱发闪光错觉的大脑静息态低频振幅

声音诱发闪光错觉(sound-induced flash illusion, SiFI)是一种听觉占主导性的多感觉整合现象, 即当视觉闪光伴随不相等数量的听觉声音在100 ms内相继或同时呈现时, 个体会错觉性地知觉到视觉闪光的个数与听觉声音的数量相等。本研究分别将老年人群体和年轻人群体的声音诱发闪光错觉量(裂变错觉和融合错觉)与全脑的静息态低频振幅(amplitude of low-frequency fluctuation, ALFF)进行相关分析, 考察老年人群体声音诱发闪光错觉效应与大脑静息状态自发活动区域的关系。结果发现, 无论是裂变错觉还是融合错觉, 老年人声音诱发闪光错觉均增大。对于裂变错觉, 老年人的错觉量与内侧前额叶皮层的自发活动呈显著正相关; 对于融合错觉, 老年人的错觉量与额下回、额中回和颞下回的自发活动呈显著正相关, 与枕上回和舌回的自发活动呈现显著的负相关。结果表明, 老年人声音诱发闪光错觉量增大的原因与大脑中多个脑区的静息态自发活动存在关系。     

Nicotine and familial vulnerability to schizophrenia: a discordant twin study

Tobacco use is significantly associated with schizophrenia. However, it is not clear if smoking is associated with the illness itself, treatment, or underlying vulnerability to the disease. Smoking was studied in a sample of schizophrenic probands (n = 24), their unaffected co-twins (n = 24), and controls (n = 3,347). Unaffected co-twins had higher rates of daily smoking than controls. Probands and co-twins were more frequently unsuccessful in attempts to quit than controls. Probands reported shaky hands and depression following smoking cessation more often than controls, whereas unaffected co-twins reported difficulty concentrating, drowsiness, nervousness, and headache following smoking cessation more often than controls. Results are consistent with the hypothesis that nicotine use is influenced by familial vulnerability to schizophrenia, not just clinical schizophrenia per se.     

Place learning in virtual space III: Investigation of spatial navigation training procedures and their application to fMRI and clinical neuropsychology

This paper describes the utilization of a desktop virtual environment task, the Computer-Generated (C-G) Arena, in the study of human spatial navigation. First, four experiments examined the efficacy of various training procedures in the C-G Arena. In Experiment 1, participants efficiently located a hidden target after only observing the virtual environment from a fixed position (placement learning). In Experiment 2, participants efficiently located a hidden target after only observing an experimenter search the virtual environment (observational learning). In Experiment 3, participants failed to display alatent learning effect in the virtual environment. In Experiment 4, all training procedures effectively taught participants the layout of the virtual environment, but the observational learning procedure most effectivelytaught participants the location of a hidden target within the environment. Finally, two experiments demonstrated the application of C-G Arena procedures to neuroimaging (Experiment 5) and neuropsychological (Experiment 6) investigations of human spatial navigation.
