Social Interaction

This preregistration documents an experiment examining the effects of acute stress and social context on alcohol-related decision-making. The study uses a 2x2 factorial design (stress vs. control × social vs. alone) with dyadic recruitment.

Several international studies indicate that men with reduced semen quality often feel overlooked in the context of fertility treatment. Men who undergo fertility treatment due to their own infertility, exhibit increased concern and experience more negative emotions such as loss, stigmatization, and low self-esteem - more so than men undergoing fertility treatment for other reasons. Since 2008, there has been limited research on the experiences of male patients with infertility in Denmark. Furthermore, there is generally very little knowledge regarding the testosterone levels (hypogonadism) of male infertile patients and its association with quality of life. Thus, there is a lack of updated insight into how infertile men experience their situation today. Additionally, the present study finds it relevant to examine whether men's needs and experiences in interactions with health professionals have changed over the past 15 years.

The purpose of the PeerScreen trial is to investigate whether reducing screen media use affects mental health, social interaction, sleep, physical activity, heart rate variability, and behavioral patterns in young people aged 13 to 24 years. The primary question the trial aims to answer is: Does reducing screen media use over a 4-week period improve mental health among young people? Researchers will compare a screen media reduction intervention with a control condition in which participants continue their usual screen media use to determine whether reducing screen media use leads to improvements in mental health. Participants will: * be allocated to either a 4-week screen media reduction intervention or a control condition * complete a study protocol including questionnaire-based assessments, daily self-reports, and objective monitoring of screen media use, sleep, physical activity, heart rate variability, social interactions, and geolocation

This study will examine the effects of social support on threat vigilance and arousal using eye tracking. We will also test the moderating effects of trauma and discrimination history.
