Latent state trait theory (LST theory; Eid et al., 2017; Steyer et al., 2015) is one of the most influential theories in psychology for studying trait change and variability processes. Latent state trait (LST) models are commonly used to analyze complex longitudinal data (e.g., panel data or intensive longitudinal data). In this project, we further develop LST models to include both time-varying and time-invariant variables to explain differences in model parameters representing additive and multiplicative trait changes and/or different variability processes (e.g., intra- versus interindividual differences). The new approach is termed moderated nonlinear latent state trait analysis (MN-LST; Oeltjen et al. 2022) and is performed in a fully Bayesian framework, which allows for the inclusion of prior knowledge and model evaluation by means of posterior predictive checks and leave-one-out cross-validation. MN-LST analysis is currently being extended to causal inference and continuous time models.

Beliefs and ideas about aging begin to form early in life. Many events signal the importance of age for our social selves: birthday parties, entrance to school, or acquiring a driver’s license. Children are sorted into classrooms based on age and the work opportunities available to adults often hinge on age. In this pilot project we investigate how individuals learn about and form attitudes regarding age, ageing, and age-groups, and how these attitudes influence our treatment of those who are older or younger than ourselves.

Social interactions have profound effects on human well-being, with stable attachments promoting mental and physical health and social isolation leading to negative outcomes. Our project focuses on the crucial developmental stage of young adulthood, which is characterized by navigating new social dynamics and building important social networks. Through the use of innovative technologies, such as experience sampling methods and Bluetooth-enabled devices, we aim to capture real-time social interactions in various real-world contexts. Through integration with the German National Educational Panel Study (NEPS), we also aim to investigate the complex relationship between social interactions, health outcomes and developmental predictors. This project contributes to the Infrastructure Priority Program "New Data Spaces for the Social Sciences" (SPP 2431, https://www.new-data-spaces.de/en-us/) and advances Research Area 4 by providing new insights through multi-method ambulatory assessment studies. By developing innovative technologies and new statistical methods, we enable researchers to explore with high precision and validity how social interactions influence health and development outcomes.

IMPULS is a project that combines life science, data science, and social science to better understand human aging. One of the project’s aims is to examine the influence of psychological aging on the aging process, and its relation to biological and epigenetic markers of aging (cell age, brain age). The project draws from a large sample of middle-aged and old adults in the age range from 40-90 years who participated in the Ageing-as-Future project to assess different types of aging indicators. With its interdisciplinary approach to aging, IMPULS is a unique project that may lead to a breakthrough in understanding aging mechanisms.

Talking to others to share good news, concerns, or recent experiences is part of everyday life. Such interactions provide the stage for important areas of development throughout the entire life course; they may also facilitate and influence individual development. In this DFG-funded project, we use multiple methods to investigate how older adults behave and understand each other during conversations. What interpersonal mechanisms contribute to successful interactions? How do people differ in this regard, and can we influence these differences? How do speakers and listeners contribute to mutual understanding, and what is the role of verbal, paraverbal, and nonverbal signals? We investigate these and other lifespan-related questions using experiments and self-reports as well as linguistic and video analyses.

Based on long-standing experience of the group in research on cognitive aging and its neuronal correlates, as well as with individuals experiencing handicaps of social communication, this project develops and evaluates perceptual and cognitive training programs and tailor-made interventions to improve various aspects of social interaction. Our approach is based on current neurocognitive models of social perception and interaction. Selected sub-projects use current technology to synthesize naturalistic facial and vocal stimuli with paremeter-specific morphing methods. This technology allows us to create stimuli with augmented („caricatured“) social signals which have been demonstrated to be efficient in improving social perception. Individual aspects of this research programme include (1) an assessment of emotion perception abilities in hearing-impaired individuals with a cochlear implant, (2) the development and evaluation of a training program for improving nonverbal vocal communication in older adults, (3) a systematic assessment of the potential of mu-rhythm neurofeedback training to improve socio-emotional communication and its related cortical correlates in adolescents and young adults with autism, and (4) the development of improved methods for assessing central auditory processing disorders (CAPD; dt: AVWS) - a frequent but incompletely understood cause of learning problems for school children. The subprojects of InterTrain are all characterized by use of state-of-the-art digital technology to assess and improve social interaction abilities.

Empirical evidence on how affective experiences change over the lifespan paints a heterogeneous picture depending on a variety of factors. One source of variability is the diversity of studied affective facets that range from general well-being over affect dimension (e.g., positive vs. negative affect) to distinct emotions (e.g., anger, sadness). In addition, researchers rely on diverse measures that, amongst others, refer to different time frames of affective experience (e.g., momentary or retrospective) and answering scales (e.g., intensity or frequency). Evidence suggests that these characteristics are associated with variance in individual reports as they depend on different memory systems, require different levels of abstraction, and/or tackle distinct affective features. Hence, they may also be related to differences in affective change over the lifespan. In the present project, we capitalize on existing longitudinal data on mean-level change in affect and apply meta-analytical procedures to address that question.

Studying the ebb and flow of affect in daily life provides important insights into psychological functioning and well-being. The MIVA project (“Modeling Intraindividual Variability in Affect”) aims at improving our understanding of why individuals show fluctuations in affect, and in explaining individual differences in the underlying processes that determine affective variability, with a particular focus on age group differences. Research in the MIVA project is based on a newly developed mathematical model that incorporates theoretical ideas about affect generation and regulation. Using this model, we address our research aim by combining different methodological approaches that mutually complement and inform each other. Computational methods provide insights into the model’s behavior and can link theoretically derived parameters to simulated affective fluctuations. Ambulatory assessment methodologies will allow us to measure affective processes as they naturally occur in the daily lives of adults from various age groups. Simulation studies and ambulatory assessments will be complemented with experimental paradigms assessing affective micro-processes in the laboratory.

The MOMO study examines in-situ motivational processes during learning in a sample of university students attending a weekly lecture. It particularly focuses on two types of beliefs that students hold in specific learning situations: Momentary task values (e.g., how useful are the contents taught) and momentary success expectancies (e.g., how well do students think they understand what is taught). The study used smartphone-based electronic diaries to capture these situational values and expectancies in the moment in which they are experienced (Experience Sampling Method).

In this project, we investigate normative expectations about the ageing process, life in old age, and older people. We focus on two such normative expectations, namely that older adults should remain active and healthy (active aging) and that older adults should behave altruistically towards the younger generations (altruistic disengagement). The project considers the following interrelated research questions (1) How these norms are cognitively represented (domain-specificity of the norms, relation between active ageing and disengagement), (2) which factors influence personal endorsement of these norms (generating arguments, changing perspectives, social consensus feedback), (3) which attitudes and motivations a person develops in response to ageing-related normative expectations, and (4) how ageing-related normative expectations affect behavioural intentions, and actual behaviours. To address these research questions, the project relies on a powerful mix of research designs: analysing available longitudinal survey data and conducting a series of experimental studies.

The 2008-launched German Family Panel pairfam ("Panel Analysis of Intimate Relationships and Family Dynamics") is a multi-disciplinary, longitudinal study for researching partnership and family dynamics in Germany. The annually collected survey data from a nationwide random sample of more than 12,000 persons of the three birth cohorts 1971-73, 1981-83, 1991-93 and their partners, parents and children offers unique opportunities for the analysis of partner and generational relationships as they develop over the course of multiple life phases.
The German Family Panel is a cooperative effort linking the University of Bremen, the Chemnitz University of Technology, the Friedrich Schiller University of Jena, the University of Cologne, and the Ludwig Maximilian University of Munich. Since 2010, pairfam has been funded as a long-term project by the German Research Foundation (DFG). It is advised by an international board and accredited as a research data center by the German Data Forum (RatSWD). A close collaboration exists with the Max Planck Institute for Demographic Research and TNS Infratest Sozialforschung.

The Jena team is responsible for the research area of partner relationships and personality development.

A pragmatic trial to evaluate the effectiveness of a graduated-intensity counseling approach with care counseling and telephone-based short-time psychotherapy

Providing qualified assistance in order to sustain family caregiving and improve health and quality of life for caregivers is a major challenge of an aging population. The severe health impacts on family caregivers such as higher morbidity and mortality, higher prevalence of depressive disorders and symptomatology, have been documented in a large number of studies.
The primary aim of the study “ReDiCare” is to evaluate a new counselling approach for distressed caregivers that extends the current counselling delivered by long term care insurances and care support centers. In ReDiCare, a stepped intervention combining care counselling followed by a telephone-based psychotherapy for non-responders is compared with routine care in a translational study. If the emotional burden is persisting after the care counseling over 3 months, the caregivers of the intervention group will be offered further support by psychotherapists over 6 months. To proof the efficacy of the stepped intervention, the participating caregivers are examined by telephone at baseline and after 3, 9, and 15 months. The proof of efficacy also involves a detailed process evaluation.

More and more people in Germany live alone (currently approximately 20% of the adults). The aim of the RIKSCHA project (funded by the German Research Foundation) is to identify the psychological and social conditions under which living alone can succeed and foster individual well-being. More specifically, we aim to investigate the dynamic transactions between social motives and personal relationships in the individual social networks of middle-aged individuals living alone.

In several projects, we develop and evaluate short interventions (e.g., counseling feedback, exercises) for supporting socio-emotional and cognitive competences of different age groups, covering lifespan from early childhood to retirement age.
Some short interventions we focus on include, amongst others:
• The online survey ‚Bildungs- und Erziehungstest für TagesElternBetreuung (BET)‘ (‘Educational and Parenting Test for Home-Based Child Care’, EPT);
• The online platform ‘Fühlerei’, providing digital emotion-related exercises for different target groups;
• Classic courses to increase emotional competencies and stress management skills in young adults in attendance;
• The cognitive training programs by Karl Josef Klauer and colleagues for different age groups;
• Socio-emotional competence and resilience trainings (e.g., by Franz Petermann et al.).

Our main research questions are:

How can we foster emotional competencies in different age groups?
How can we foster cognitive competencies in different age groups?
Which (age or social) groups of people should particularly be addressed to foster competencies?
To answer these questions, we apply various methods such as quasi-experimental studies, surveys, psychometric tests, video observations, as well as pre-, post-, and follow-up-test designs with interventions and meta-analyses.

This ongoing longitudinal project investigates how individuals perceive, construe, and prepare for their old age and ageing. We address this topic from an interdisciplinary perspective, combining different methodological approaches that mutually complement and inform each other (questionnaires, online assessments, in-depth interviews, experiments). The project has an international format, with data collection in five different countries (Germany, USA, Hong Kong, Czech Republic, Taiwan), which allows us to study and compare processes of ageing across different societal contexts. The major topics of our project center around the following interrelated themes: Views on ageing, perceived age discrimination, preparation for old age, ageing during the “fourth age”, attitudes toward longevity, and time management in old age.

The Medit-Ageing/Silver-Sante study investigates how interventions based on meditation training, foreign language acquisition or health training can contribute to healthy ageing. The work package Emotion investigates the role and plasticity of emotional processes and associated neural functions in old age. To this end, we have developed an innovative task to measure brain activation during and after emotionally challenging events - the Socio-affective Video Task Rest (SoVT-Rest; Baez-Lugo et al., 2023; Nature Aging). Using this paradigm, as well as other behavioural tests, questionnaires, partner surveys and neuro-biological measures, we examine how positive emotions contribute to mental and physical well-being in old age over time.
