When AI speaks
Platform societies already shape how users communicate, participate, and become visible. The rise of generative artificial intelligence (GenAI), through systems such as ChatGPT and Grok, may further deepen these dynamics, introducing new and fundamental challenges to freedom of expression, including questions of authorship. However, despite the expanding reach of this technology, research on how users understand of GenAI’s influence on expressive…
Beyond Utility
Human-AI relationships are increasingly marked by emotional depth, intimacy, and social expectations. While interpersonal conflicts are common in human-human relationships, they remain underexplored in human-AI contexts. Drawing on the social penetration theory, this paper examines conflicts between humans and social AIs such as Replika, Character.ai, and ChatGPT. We conducted a questionnaire study with 94 participants in close, friendship-like, …
Understanding model power in social AI
Given the widespread integration of Social AI like ChatGPT, Gemini, Copilot, and MyAI, in personal and professional contexts, it is crucial to understand their effects on information and knowledge processing, and individual autonomy. This paper builds on Bråten’s concept of model power, applying it to Social AI to offer a new perspective on the interaction dynamics between humans and AI. By reviewing recent user studies, we examine whether and ho…
Why do people use ChatGPT? Exploring user motivations for generative conversational AI
Generative conversational artificial intelligence (AI), such as ChatGPT, has attracted substantial attention since November 2022. The advent of this technology showcases the vast potential of such AI for generating and processing text and raises compelling questions regarding its potential usage. To obtain the requisite knowledge of users’ motivations in adopting this technology, we surveyed early adopters of ChatGPT (n = 197). Analysis of free t…
A longitudinal study of human–chatbot relationships
Social chatbots have become more advanced, paving the way for human–chatbot relationships (HCRs). Although this phenomenon has already received some research attention, the results have been contradictory, and there is uncertainty regarding how to understand HCR formation. To provide the needed knowledge on this phenomenon, we conducted a qualitative longitudinal study. We interviewed 25 participants over a 12-week period to understand how their …
My AI Friend
Use of conversational artificial intelligence (AI), such as humanlike social chatbots, is increasing. While a growing number of people is expected to engage in intimate relationships with social chatbots, theories and knowledge of human–AI friendship remain limited. As friendships with AI may alter our understanding of friendship itself, this study aims to explore the meaning of human–AI friendship through a developed conceptual framework. We con…
Young people's use and experience of the Internet during the Covid-19 lockdown
No studies we are aware of have explored youth’s experiences of the association between their Internet use and well-being during the COVID-19 lockdown. To fill this void, we used survey data of a representative sample (N = 734) of young Norwegians (16–26 years) collected a few weeks into the lockdown in May 2020. Findings show a substantial increase in use of several Internet activities—in particular, video calls and streaming services. Snapchat …
My Chatbot Companion - a Study of Human-Chatbot Relationships
There has been a recent surge of interest in social chatbots, and human-chatbot relationships (HCRs) are becoming more prevalent, but little knowledge exists on how HCRs develop and may impact the broader social context of the users. Guided by Social Penetration Theory, we interviewed 18 participants, all of whom had developed a friendship with a social chatbot named Replika, to understand the HCR development process. We find that at the outset, …

From Youthful Experimentation to Professional Identity
The process of self-presentation is significantly complicated for people growing up with social media. Many individuals have time-stamped digital footprints in social media from early youth to adulthood. However, little is known about long-term consequences for these individuals, their experience of time and their identity transition from youthful experimentation to a professional identity in social media. Through 15 in-depth interviews, our stud…
Chatbots
Chatbots have been around for decades. However, the real buzz around this technology did not start until the spring of 2016. Reasons for the sudden renewed interest in chatbots include massive advances in artificial intelligence (AI) and a major usage shift from online social networks to mobile-messaging applications such as Facebook Messenger, Telegram, Slack, Kik, and Viber. The first of these reasons holds promise that intelligent chatbots may…
Losing Control to Data-Hungry Apps
Personal data from mobile apps are increasingly impacting users’ lives and privacy perceptions. However, there is a scarcity of research addressing the combination of (1) individual perceptions of mobile app privacy, (2) actual dataflows in apps, and (3) how such perceptions and dataflows relate to actual privacy policies and terms of use in mobile apps. To address these limitations, we conducted an innovative mixed-methods study including a repr…
Time Collapse in Social Media
Context collapse, or the flattening of multiple audiences into a single context, has been an important notion in research on privacy experiences, self-performance, and changing user practices in social media. Yet, previous research has mainly addressed context collapse in spatial rather than temporal terms. The resulting lack of an understanding of time in social media limits our conception of the social media context. The aim of this article is …
Trust and distrust in online fact-checking services
Even when checked by fact checkers, facts are often still open to preexisting bias and doubt.

How Journalists and Social Media Users Perceive Online Fact-Checking and Verification Services
While services for fact-checking and verification to counter fake news in social media have increased, little research has investigated how journalists and the public perceive such services. This study reflects the outcomes of REVEAL, a three-year European Union research project investigating the use and impact of services for fact-checking and verification. Based on interviews with 32 young journalists and content analysis of social media users’…
Emerging Journalistic Verification Practices Concerning Social Media
The verification of social media content and sources are increasingly critical to journalists and news organisations. In this study, we report on findings from qualitative interviews conducted with 24 journalists working with social media in major news organisations in Europe. Our findings contribute to new knowledge on journalists' social media working practices. We find that social media content are often used as the primary news source, and jo…
Facebook is no “Great equalizer”
Facebook is expected to facilitate more equal participation in civic engagement across genders and countries. With the use of a big data tool (Wisdom), we explored gender disparities in various Facebook liking practices concerning expressions of civic engagement among 21,706,806 Facebook users in 10 countries across Asia, Africa, the Americas, and Europe. We observed distinct patterns with regard to civic and political expressions on Facebook, wi…
My children tell me it’s so simple’
While there has been a great deal of research on younger people using Social Networking Sites (SNSs), there has been less work on older people and non-users. We present a mixed-methods design with a technology-acceptance survey and focus-group interviews to study older Norwegian non-users’ perceptions of SNSs. Our study reveals that most non-users in our sample deliberately do not use SNSs. They perceive SNS communication as cold and narcissistic…
Social Networking Sites
The rapid adoption of social networking sites (SNSs) raises important questions about the social implications of such usage. Drawing on unique longitudinal data, surveying a representative sample of Norwegian online users (N = 2,000, age 15-75 years) in 3 annual waves (2008, 2009, and 2010), this study found a significantly higher score among SNS users in comparison to nonusers in 3 out of 4 social capital dimensions: face-to-face interactions, n…

Norwegian Children's Experiences of Cyberbullying When Using Different Technological Platforms
Cyberbullying is an emerging threat to children in Europe. However, European research into this topic is scant and knowledge of it incomplete. In this study, “cyberbullying” involves the use of different technological platforms to support hostile behavior by an individual or group that harm others. The article examines whether children's experience of cyberbullying differs according to technological platforms and socio-demographic variables. Resu…
Why People Use Social Networking Sites
Children's usage of media technologies and psychosocial factors
Media use has changed considerably during the past five years and earlier research has produced contradictory results on how media use links to children's psychosocial factors. This study charts the access to and use of several media technologies among 825 Norwegian schoolchildren between 10 and 12 years of age. The questionnaire contained items concerning children's self-concept, parental monitoring and social competence. It found that children …
In the borderland between family orientation and peer culture
This article explores the use of mediated communication among Norwegian children aged between 10 and 12 years. The analysis is based on a survey and 88 qualitative interviews with 130 children about their use of different types of communication technologies. This allowed a sketch of connections between the nature of the childrens' social relationships, mediated content and various means of communication employed. Six main content categories of me…
