Experimental studies on effects of media usage

Introduction

About the working group

This working group investigates the short-term effects of modern technology usage on well-being, especially among children and adolescents. In our research, we utilize and combine theories formulated within the field of psychology, media studies, and communication studies. These perspectives guide our attention towards the role of (inter)individual characteristics, specifics of online communication and interaction processes, and recognition of the importance of affordances of diverse online environments. As a result, we aim to capture the role of both socio-psychological characteristics of users and online cues in the effects of incidents mirroring media usage on adolescents’ well-being.

The core methodological approach of this group is centered on the usage of experimental designs. This comprises more traditional procedures, such as manipulation with selected stimuli representing online environments and specific incidents (e.g., acts of cyberaggression), enriched by the inclusion of recent approaches, especially the usage of eye-tracking technology. Moreover, we also plan to use qualitative methods to contextualize our findings. The usage and triangulation of more approaches and methods aims to provide rich and complex data.

Our experiments are based on thoroughly developed designs, emphasizing the strong theoretical rationale and high internal validity increased by cognitive pilots with adolescents. Experiments are preceded by power analyses conducted with regard to pre-designed analytical plans and pre-registration.

What we do

Our focus

Our experiments follow several topical areas related to media usage and effects on well-being. Currently, we focus on several topics related to cyberaggression. We are examining more types of aggression within this stream, including peer-to-peer aggression, cyberhate, violent content, or ostracism online. In other research areas, we look at the effects of exposure to online materials on the relationship to one’s body. In relation to health, we investigate the assessment of health-related online information.
