Cue reactivity and craving, or the strong desire to consume a substance, are considered to be underlying mechanisms in the development and maintenance of substance use disorders. Implicit cognitive mechanisms are described as further key components of an addictive behavior, including attentional bias for a substance and implicit associations with substance intake. The I-PACE (Interaction of Person-Affect-Cognition-Execution) model provides a theoretical framework describing key concepts of the development and maintenance of an addictive behavior, which also encompasses the interplay of cue reactivity, craving, and implicit cognitions. It is assumed that stress may influence affective and cognitive responses in individuals with behavioral addictions, including those with Internet use disorder. One of the most significant changes to the buying-shopping environment is the migration of traditional acquisition of goods to the online retail market, potentially contributing to nowadays predominantly online buying-shopping disorder. Communication behaviors are also changing, and a growing number of individuals are suffering from negative consequences and diminished control due to overuse of online communication applications. With the inclusion of gaming disorder in the ICD-11 as a disorder due to addictive behavior, buying-shopping disorder and social network use disorder are discussed as further specific types of Internet use disorders. Previous studies mainly show the relevance of cue reactivity and craving in both addictive behaviors, and of implicit cognitions in buying-shopping disorder. Research on implicit cognitions in social network use disorder, effects of acute stress, and the interaction of these aspects in both specific Internet use disorders are lacking. The research project addresses the predictive role of acute psychosocial stress for cue reactivity, craving, and addiction-related implicit cognitive processes in four groups, namely women with 1) buying-shopping disorder and 2) social network use disorder, compared to women with 3) non-problematic buying-shopping behavior and 4) non-problematic use of social networks. Besides the surveys and structured interviews for the diagnostics and the experimental and neuropsychological tasks of the core battery, an Implicit Association Test and a dot-probe task with addiction-related stimuli will be administered. The role of acute stress will be investigated using the standardized Trier Social Stress Test compared to a non-stressful control condition. The research project is strongly linked to RP2 and RP4, since these projects will examine effects of acute stress on cue reactivity in buying-shopping disorder (RP2), gaming disorder, and pornography use disorder (RP4). Further synergy effects are expected with RP8, addressing implicit cognitions in social network use disorder, and with RP7, addressing implicit associations in different addictive behaviors as well.

提示反应性和渴望，或者对食用物质的强烈渴望被认为是物质使用障碍的发展和维持中的基本机制。隐式认知机制被描述为上瘾行为的进一步关键组成部分，包括物质的注意偏见以及与物质摄入的隐式关联。 i-pace（人与人认知执行的相互作用）模型提供了一个理论框架，描述了成瘾行为发展和维护的关键概念，这也涵盖了提示反应性，渴望和隐式认知的相互作用。假定压力可能会影响行为成瘾的个体，包括互联网使用障碍的人的情感和认知反应。购买购物购物环境的最重大变化之一是将商品收购迁移到在线零售市场上，这有可能导致当今主要是在线购买购物中心障碍。沟通行为也在发生变化，越来越多的人由于过度使用在线通信应用程序而遭受负面后果和控制力减少。由于成瘾的行为，ICD-11中的游戏障碍作为一种疾病，购买购物障碍和社交网络使用障碍被讨论为进一步的特定类型的互联网使用障碍。先前的研究主要表明提示反应性和渴望在上瘾行为中的相关性以及购买购物障碍中隐性认知的相关性。关于社交网络使用障碍中隐性认知，急性压力的影响以及这些方面在两种特定互联网使用障碍中的相互作用的研究。该研究项目探讨了急性社会心理压力在四组中的提示反应性，渴望和与成瘾相关的隐式认知过程中的预测作用，即患有1）男性和2）社交网络使用障碍，与具有3）非问题的购买行为和4）非问题的社交网络的女性相比进行了社交网络使用障碍。除了针对诊断的调查和结构化访谈以及核心电池的实验和神经心理学任务外，还将进行隐式关联测试以及与成瘾相关刺激的点探针任务。与非压力控制条件相比，将使用标准化的TRIER社会压力测试研究急性应力的作用。该研究项目与RP2和RP4密切相关，因为这些项目将检查急性应力对购买购物中心障碍（RP2），游戏障碍和色情使用障碍（RP4）中提示反应性的影响（RP4）。 RP8预计会进一步的协同作用，解决社交网络使用障碍中的隐式认知，以及RP7，还解决了不同成瘾行为的隐性关联。
