1J ürgen M aier is a professor of political communication in the Department of Political Science at the University of Koblenz-Landau, Landau, Germany. J. F elix H ampe is a professor of corporate communication systems in the Department of Information System Research at the University of Koblenz-Landau, Koblenz, Germany. N ico J ahn is a research assistant in the Department of Information System Research at the University of Koblenz-Landau, Koblenz, Germany. The development of the mobile RTR system and the data collection for the smartphone study were supported by a grant from the Rhineland-Palatinate Ministry of Education for the Research Network "Communication, Media, and Politics" at the University of Koblenz-Landau [to J.M. and J. F. H.].
Mobile real-time response (RTR) measurement using a smartphone app offers a reliable alternative to lab studies. This technology validates electronic media analysis outside the lab, enabling large-scale research on media impact.
Area of Science:
- Media Psychology
- Human-Computer Interaction
- Communication Technology
Background:
- Real-time response (RTR) measurement is crucial for analyzing media processing but often limited to lab settings.
- Concerns about the external validity of lab-based RTR studies persist due to artificial reception environments.
- Technical requirements, particularly data synchronization, have historically hindered mobile RTR applications.
Purpose of the Study:
- To introduce a novel smartphone application for mobile real-time response (RTR) measurement.
- To address the challenge of automatic synchronization in mobile RTR data collection.
- To assess the reliability and external validity of mobile RTR measurement compared to traditional lab-based methods.
Main Methods:
- Development of a smartphone app utilizing the dial technique for capturing real-time responses.
- Implementation of an automatic synchronization solution for mobile RTR data.
- Comparative study involving two samples (lab vs. home) analyzing real-time reactions to a televised political debate.
Main Results:
- The mobile RTR system demonstrated comparable results to traditional lab-based RTR measurements.
- Mobile RTR data exhibited similar reliability and validity to laboratory findings.
- The study provides evidence supporting the external validity of lab-based RTR studies by showing similar results in naturalistic settings.
Conclusions:
- Mobile RTR measurement outside the laboratory is feasible and reliable.
- The findings challenge the notion that artificial reception situations inherently produce artificial results.
- Mobile RTR technology facilitates large-scale studies, enhancing the understanding of electronic media content processing and impact.
