For large parts of the population the use of social media, such as Facebookor Instagram, has become an elemental part of the daily routine. It is thusimportant that research investigates the impact that this technology has onour lives. Excessive social media usage is often referred to as an "addiction"in mass media outlets and public discussion. However, many psychologistshave warned about the perils of medicalising everyday behaviours. Thepresent PhD project will apply reward-based models derived from thesubstance addiction literature (Berridge & Robinson, 2016) to investigatewhether excessive social media use displays the neurocognitivecharacteristics of an addiction in some individuals. The project will utiliseestablished experimental paradigms to assess attentional bias to reward,approach motivation, and reward cue reactivity in response to social mediastimuli at multiple levels and through different measurement modalities (selfreports,implicit behavioural, psychophysiological and neural). Recentreviews also highlight the need for more qualitative measures of the motivesand functions underlying 'behavioural addictions' (Kardefelt-Winther et al.,2017). Thus, by integrating both experiential and implicit measures ofreward, the present project aims to establish subjective and objectiveincentives behind excessive social media usage. Not only will this help us toavoid over/under-pathologising daily life activities, the findings may alsohave substantial implications for the development of more efficaciousprevention and intervention strategies when those activities have harmfulconsequences.

对于大部分人来说，使用社交媒体，如facebook或Instagram，已经成为日常生活的一个基本组成部分。因此，研究这项技术对我们生活的影响是很重要的。在大众媒体和公众讨论中，过度使用社交媒体通常被称为“成瘾”。然而，许多心理学家警告说，将日常行为医学化是有危险的。目前的博士项目将应用源自物质成瘾文献的基于奖励的模型（Berridge & Robinson, 2016）来调查过度使用社交媒体是否会在某些个体中显示成瘾的神经认知特征。该项目将利用已建立的实验范式，在多个层面上通过不同的测量模式（自我报告、内隐行为、心理生理和神经）来评估对社会媒体刺激的注意偏见、接近动机和奖励线索反应。最近的观点也强调需要对“行为成瘾”背后的动机和功能进行更多定性测量（Kardefelt-Winther et al.,2017）。因此，通过整合体验和隐性奖励措施，本项目旨在建立过度使用社交媒体背后的主观和客观激励机制。这不仅可以帮助我们避免日常生活活动的过度病理化或病态化，而且当这些活动产生有害后果时，研究结果也可能对开发更有效的预防和干预策略具有重大意义。
