The Multi-Method Ambulatory Assessment (MMAA) Project

The goal of this project is to chart age differences in affective experiences and their interrelations with motivational, cognitive, and physiological processes over time. Since 2007, four longitudinal measurement phases have been conducted in 400 individuals aged 12 to 85+ years. Further measurements are planned. We combine ambulatory assessment methodologies, which allow measurements of experiences, cognitive capacity, and physiological processes in daily-life contexts, with interview techniques and well-controlled experimental paradigms. Ambulatory assessment methods include mobile phone-based experience sampling, and ambulatory bio-monitoring of cardiac activity, physical activity, and hormonal processes.
