A | 北京时间1月14日早些时候,TechCrunch报道说,密歇根州立大学的研究人员正在探索社交媒体成瘾的概念。

Located on a hilly terrace west of the Taihang Mountains and flanked by the Songxi River, the site was excavated in 2024 and 2025 by the Shanxi Provincial Institute of Archaeology and partner institutions, leading to the discovery of 18 tombs, including six Xia Dynasty burial sites and 12 Warring States Period (475BC-221BC) graves. 
"These are the highest-ranking Xia aristocratic tombs discovered so far, indicating that this location was a regional center," the institute said.
The Xia Dynasty is traditionally regarded as China's first hereditary dynasty, though contemporaneous written records are lacking.
The well-organized Xia tombs, concentrated in the western part of the cemetery, feature uniform east-west oriented vertical earthen pits. Researchers recovered nearly 40 sets of artifacts with distinctive local cultural characteristics, including pottery, lacquerware and turquoise ornaments. 
Extended regional surveys across the Songxi River valley yielded more than 10 Xia and Shang period sites. Test excavations at nearby relic sites unearthed pottery fragments, stone tools, bronze knives, as well as tin-bronze ingots and smelting residue, providing solid evidence of early metal mining and craftsmanship. 
Local copper-iron symbiotic ore deposits confirm exploitation of these resources during the Xia and Shang eras, while typical cultural artifacts found in adjacent counties reveal widespread regional cultural exchange.
Multidisciplinary analyses further decoded the civilization's features. Ancient human remains belong primarily to the ancient population of the Central Plains with minor Mongolian Plateau ­genetic traits, forming a stable patrilineal clan. The community relied on millet farming and maintained long-distance resource trade networks. 
Artifact provenance tests trace scallop shell ornaments to the Bohai Sea, cinnabar to Hunan-Guizhou ore belts, turquoise to the eastern Qinling Mountains area, and coffin timber to local Taihang pine trees. Such diverse materials reflect close interaction among the Taihang foothills, the press release noted.
Lab restoration unveiled refined ritual relics, including a dragon-patterned lacquer cylinder with red and black stripes and an intact lacquer gu vessel (a type of wine vessel). Turquoise plaques from the site match specimens from the Erlitou site, a core Xia cultural relic, proving ­cross-regional cultural interaction. Radiocarbon dating places the site's active period between 1880BC and 1450BC, aligning with the late Xia Dynasty.
Scholars confirmed the findings have helped reshape academic understanding of Xia-Shang civilizations and reconstruct multi-level settlement patterns on the western Taihang foothills, while offering new insights into social complexity and civilization development in early China.
。他们发现,在日常生活中,使用社交媒体网站的人表现出与可卡因或海洛因上瘾者相似的行为特征。相关论文已发表在《行为成瘾杂志》上。该研究首先要求71名参与者使用Bergen-Facebook成瘾量表对他们使用Facebook的情况进行评分。然后,受试者继续完成爱荷华游戏任务(IGT),这是一个评估决策能力受损程度的经典研究工具。

B | 具体方法是向参与者展示四包卡片和四组卡片。每张卡片都显示了获得或损失的金额。要求参与者在其中进行选择,以最大限度地提高收益。

C | 正如研究中解释的那样,“参与者还被告知,有些卡片比其他的好,如果他们想做得好,就应该避免坏卡片,选择好卡片。”研究人员发现,声称自己是Facebook过度用户的参与者在IGT上的表现比他们的同龄人差,他们选择了两张“坏”卡片,提供即时B。但最终导致了损失。在IGT的后一部分,当参与者有足够的时间观察卡片并知道哪些卡片预测了最大的风险时,实验中显示的行为差异具有统计学意义。从额叶脑损伤患者到海洛因依赖者,IGT已被广泛应用于各个研究领域,但作为一种检测社交媒体依赖者的手段,它仍然是一种创新的方法。随着结构研究的不断深入,研究者们可以肯定地将现有的学习物质成瘾的方法论框架应用于社交媒体用户。

D | 虽然上述研究范围较窄,但很有意思,为后续研究提供了一些方法。

E | 研究人员已经意识到,在理想的研究状态下,研究人员可以观察参与者的社交媒体使用情况,并根据他们的行为而不是他们填写的调查对他们的社交媒体使用情况进行排名。未来的研究也可以更深入地应用于不同社交网络的过度使用用户。目前,这项研究只关注Facebook的使用,“因为它是当今世界上使用最广泛的社交网络”,但人们可以预期,Instagram每月拥有超过10亿用户,而Twitter上瘾者则少得多。
