随着人们可以获得大量信息，了解信息搜索背后的机制比以往任何时候都更加重要。在这项研究中，我们调查了健康人和成瘾者寻找信息的潜在动机。我们开发了一种新颖的决策任务和一种新颖的计算模型，该模型可以分离寻找信息的两个激励因素的相对贡献：对新颖性的渴望和对知识的普遍渴望。为了调查健康个体和成瘾个体之间寻求信息的动机是否/如何存在差异，除了健康对照之外，我们还纳入了患有赌博障碍的个体样本，赌博障碍是一种不与物质消费相混淆的成瘾形式，其特征是强迫性赌博。我们的结果表明，健康受试者和问题赌徒采用不同的信息寻求“模式”。健康的信息寻求行为主要是出于对新奇事物的渴望。相反，与健康对照组相比，问题赌徒表现出更少的新奇追求和更高的积累知识的欲望。我们的研究结果不仅为健康成瘾者寻求信息的动机提供了新的线索，而且对行为成瘾的治疗和诊断也具有重要意义。
As massive amounts of information are becoming available to people, understanding the mechanisms underlying information-seeking is more pertinent today than ever. In this study, we investigate the underlying motivations to seek out information in healthy and addicted individuals. We developed a novel decision-making task and a novel computational model which allows dissociating the relative contribution of two motivating factors to seek out information: a desire for novelty and a general desire for knowledge. To investigate whether/how the motivations to seek out information vary between healthy and addicted individuals, in addition to healthy controls we included a sample of individuals with gambling disorder—a form of addiction without the confound of substance consumption and characterized by compulsive gambling. Our results indicate that healthy subjects and problem gamblers adopt distinct information-seeking “modes”. Healthy information-seeking behavior was mostly motivated by a desire for novelty. Problem gamblers, on the contrary, displayed reduced novelty-seeking and an increased desire for accumulating knowledge compared to healthy controls. Our findings not only shed new light on the motivations driving healthy and addicted individuals to seek out information, but they also have important implications for the treatment and diagnosis of behavioral addiction.
