The rapid development of electronic communication technology has brought about a revolutionary transformation in health information seeking and medical consultation. Beyond traditional avenues like seeking assistance from doctors in hospitals, individuals now have the option to engage in online medical consultations, enhancing their ability to manage routine health effectively. However, an overreliance on online medical consultations driven by heightened health anxiety may contribute to the surge in online health information inquiries, a phenomenon positively associated with the emergence of cyberchondria. In the context of China, where HIV/AIDS is socially stigmatised, cyberchondria related to HIV infection becomes particularly noteworthy. This study delves into the potential consequences of online health information seeking (OHIS) with a specific focus on Kongai BBS, a platform catering for individuals with a fear of AIDS. Our research collected data from 309 male users actively participating in the BBS, who had engaged in high-risk sexual behaviours in the past 6 months. Applying structural equation modelling (SEM), this study examines the intricate relationships between OHIS, health anxiety, online and offline medical consultations, and cyberchondria. The results indicate that online medical consultation serves as a mediator in the relationship between OHIS and cyberchondria, whereas offline medical consultation does not significantly impact this relationship. These findings contribute valuable insights into the interactive dynamics between online and offline medical consultations, offering practical implications for the prevention of HIV infection in China.

The latent structure of psychopathology is one of the fundamental issues in psychopathology research and one which has caused considerable and prolonged debate. To determine the latent structure of depression in the Chinese population, taxometric procedures were used to evaluate the latent structure of depressive symptoms as assessed using the Center for Epidemiologic Studies Depression Scale (CES‐D). Four indicators were included: (1) depressed mood, (2) positive affect, (3) somatic, and (4) interpersonal symptoms. Participants were 6,132 individuals from a general population‐based nationwide urban sample. We applied three taxometric analyses: mean above minus below a cut, maximum eigenvalue, and latent mode as well as simulated comparison data analyses to depression data. Results of the analyses provided converging evidence for a dimensional solution. Hence, the latent structure of depressive symptoms measured using the CES‐D exists on a continuum rather than as discrete categories. Future studies using thresholds for dichotomizing depression and comparing depressed and nondepressed groups formed on the basis of CES‐D scores could be reconsidered. 相似文献

The purpose of this study was to explore variations in how contemporary couples from five different Asian regions negotiate disagreements. Video recordings of 50 couples (10 each from Japan, Korea, Mainland China, Taiwan, and Hong Kong) discussing unresolved disagreements provided raw data for quantitative and qualitative analyses. First, teams of coders from each region used a common protocol to make quantitative ratings of content themes and interaction patterns for couples from their own region. An interregional panel of investigators then performed in‐depth qualitative reviews for half of these cases, noting cultural differences not only in observed patterns of couple behavior but also in their own perceptions of these patterns. Both quantitative and qualitative analyses revealed clear regional differences on dimensions such as overt negativity, demand‐withdraw interaction, and collaboration. The qualitative results also provided a richer, more nuanced view of other (e.g., gender‐linked) conflict management patterns that the quantitative analyses did not capture. Inconsistencies between qualitative and quantitative data and between the qualitative observations of investigators from different regions were most pronounced for couples from Korea and Japan, whose conflict styles were subtler and less direct than those of couples from the other regions. 相似文献

Abstract: We examined the effect of the stimulus type and semantic categorization of the unexpected stimulus on sustained Inattentional Blindness (IB). Results showed that observers could establish attentional set based on a higher level of semantic categorization, which tuned one's attention to prioritizing semantic content over others. The unexpected stimulus, congruent with the attended objects in semantic categorization, was more likely to be noticed, whereas the incongruent semantic stimulus seemed to be unseen. Semantic category‐level attentional set played a crucial role in breaking through IB. The semantically congruent Chinese characters stimulus was detected and recognized more often than a semantically congruent picture stimulus, indicating that Chinese characters had more power to attract attention to escape sustained IB than pictures involved in visual processing. Presumably the finding of Chinese characters breaking through IB more easily might be due to the fact that Chinese characters look more distinct from pictures, rather than Chinese characters being processed more easily. Further research should be taken to test the semantic processing efficiency between pictures and Chinese characters in sustained IB. 相似文献

近年来许多行为实验和神经生理学实验都发现 ,发展性阅读障碍与基本知觉障碍有关。在视觉领域研究者提出了巨细胞障碍假设 ,这种假设认为阅读障碍者视觉神经系统中的巨细胞障碍导致他们对某种类型的视觉刺激加工存在困难 ,进而影响阅读。在听觉领域研究发现阅读障碍者加工快速、系列、短暂呈现的声音刺激存在障碍。研究者认为阅读障碍者加工快速刺激输入障碍反映了普遍的时间知觉障碍。这方面的研究发展非常迅速 ,理论观点非常明确 ,并且直接与内在的神经机制相联系 ,形成了与传统的“语言障碍”理论迥然不同的“知觉障碍”理论。“知觉障碍”理论综合了行为、认知和神经等多个层次的研究 ,反映了神经科学发展所带来的巨大影响和认知加工模块化理论的渐渐衰退。 相似文献

虽然Baddeley的工作记忆模型得到大量实验研究的支持,但是有关工作记忆和长时记忆之间的关系未能得到详细阐述。来自神经心理学的证据表明,工作记忆与情景长时记忆任务均诱发了前额区的激活,但同时发现前额区存在不同的功能分区,可能在工作记忆与情景记忆过程中具有独立的执行功能。工作记忆与情景记忆的相互作用是当前记忆研究关注的问题。已有研究发现,在情景记忆对工作记忆的作用过程中,时间进程与头皮分布均显示了年龄效应与材料加工特点。而工作记忆对情景记忆的作用中,则发现工作记忆早期加工可能对情景记忆的成功形成有更大促进作用。今后的研究应在理论模型支持下,利用多种技术手段探讨两种记忆相互作用的神经加工机制 相似文献
