The aim of the present study was to determine whether using a functionally modified sugar shaker as a food environment nudge could be an effective means to reduce the sugar used in hot beverages. Me...

Background The outbreak and global spread of COVID-19 was accompanied by an increase in reports of stigmatization of Chinese and Asian-looking people. The behavioral immune system provides a framework for stigmatization in response to infectious disease threats. Specifically, stigmatization might increase with rising levels of infectious disease th...

Research shows that retrospective memory is often more extreme than in-the-moment experiences. While investigations into this phenomenon have mostly focused on distinct, one-time experiences, we examined it with respect to recurring day-to-day experiences in the eating domain, focusing on variables of the snapshot model—i.e., the most intense and t...

Aufgrund technologischer Entwicklungen hat sich die Gesundheitskommunikation in den letzten Jahrzehnten grundlegend verändert – von einer eindimensionalen hin zu einer interaktiven und multidirektionalen Kommunikation. Das vorliegende Kapitel zielt darauf ab, die Bedeutung von Gesundheitskommunikation für Prävention und Gesundheitsförderung wie auc...

Although most people are aware of the health benefits of consuming sufficient amounts of fruit and vegetables, many do not adhere to current dietary recommendations. Recent studies have suggested meal colour variety as an intuitive cue for healthy and enjoyable lunch meal choices. The present study extends this research by testing the “colourful =...

To contain the spread of Covid-19, engagement in protective behaviors across the population is of great importance. The present study investigated protective behavior intentions during the early phases of Covid-19 in Germany (February 2–April 3, 2020) as a function of threat level and age using data from 4,940 participants in the EUCLID project. Re...

Forecasting how we will react in the future is important in every area of our lives. However, people often demonstrate an “impact bias” which leads them to inaccurately forecast their affective reactions to distinct and outstanding future events. The present study examined forecasting accuracy for a day-to-day repetitive experience for which people...
Article
Full-text available
Background: Why do we eat? Our motives for eating are diverse, ranging from hunger and liking to social norms and affect regulation. Although eating motives can vary from eating event to eating event, which implies substantial moment-to-moment differences, current ways of measuring eating motives rely on single timepoint questionnaires that assess...
Article
Full-text available
A systematic review and meta‐analysis were conducted to assess the effectiveness of app‐based mobile interventions for improving nutrition behaviours and nutrition‐related health outcomes, including obesity indices (eg, body mass index [BMI]) and clinical parameters (eg, blood lipids). Seven databases were searched for studies published between 200...
Preprint
BACKGROUND Establishing a methodology to assess nutritional behavior comprehensively and accurately is extremely challenging. Mobile technologies such as mobile applications (apps) enable eating events to be assessed in-the-moment in real-time, which reduces the memory biases that are inherent in retrospective food records. However, users might fin...

Background: Establishing a methodology for assessing nutritional behavior comprehensively and accurately poses a great challenge. Mobile technologies such as mobile image-based food recording apps enable eating events to be assessed in the moment in real time, thereby reducing memory biases inherent in retrospective food records. However, users mi...
Preprint
BACKGROUND Eating motives are diverse, ranging from hunger to affect regulation. Current psychometric measures can capture multiple eating motives, but rely on dispositional rather than idiographic approaches, neglecting the moment-to-moment variability of eating motives that are associated with the situational fluctuations of daily life. OBJECTIV...

We present SMARTEXPLORE, a novel visual analytics technique that simplifies the identification and understanding of clusters, correlations, and complex patterns in high-dimensional data. The analysis is integrated into an interactive table-based visualization that maintains a consistent and familiar representation throughout the analysis. The visua...

Full-text available
Research suggests that “healthy” food choices such as eating fruits and vegetables have not only physical but also mental health benefits and might be a long-term investment in future well-being. This view contrasts with the belief that high-caloric foods taste better, make us happy, and alleviate a negative mood. To provide a more comprehensive as...
Poster

This poster focusses on visually analyzing the behavioral signature of snacking including how much, what, when and where people snack on. Moreover, the relationship of snacking and BMI is investigated on an individual level.
Conference Paper
Full-text available
Self-monitoring is an important part of behavior intervention technologies. In order to increase the effectiveness of self-monitoring, we do not only have to track data but also give feedback to the user. In the interdisciplinary project SmartAct, we aim at developing and empirically testing the effectiveness of an open access toolbox for mobile, r...
