研究：严重的Facebook用户的决策能力受到了与吸毒者相当程度的损害。_我的网站

一 | 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。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。

三 | Dharmendra is being remembered as one of the most iconic actors of Bollywood. He has given Hindi cinema some of its rarest gems and his movies and songs still remain fresh in the memories of the audience. He has sadly passed away earlier in the morning today and his fans and followers have been sharing their heartfelt condolences in person and on social media.His family, including Hema Malini and Esha Deol have arrived at the crematorium. Many of his industry colleagues including Amitabh Bachchan, Salman Khan and more have also attended his last rites. Karan Johar, Kajol and more made special posts for the veteran actor to remember his contributions to Indian cinema.In one of his previous interviews, while talking to a leading daily about his 85th birthday, Dharmendra said, “I have lived my life to the fullest, and life has kept me young." He had further revealed that he doesn’t like to celebrate his birthday in a big way and often spends time at his farm. He had added that he often cries alone on his birthday as he misses his late mother a lot.Also Read: President Droupadi Murmu and PM Modi Mourn Veteran Bollywood Actor Dharmendra’s DemiseDharmendra made his debut in 1960 and quickly became a superstar.

四 | 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。

五 | 要求参与者在其中进行选择，以最大限度地提高收益。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。

六 | 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。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。
