Hi there 😉
I am Tian Zhou (M.Sc.), an academic staff member and PhD candidate at the University of Freiburg, Germany. I am affiliated with the Research Training Group “Statistical Modeling in Psychology” (SMiP), funded by the German Research Foundation.
With an interdisciplinary background in cognitive psychology, informatics, and human factors, my research is dedicated to elucidating the unconscious modulation of cognition and the decline of executive functions associated with aging. My current work involves analyzing a large geriatric database focusing on cognitive-motor dual-task performance in older adults. This project, undertaken in collaboration with an interdisciplinary team of psychologists, sports scientists, and gerontologists, integrates task performance data with spatiotemporal gait parameters and clinical diagnoses. Such a multifaceted approach enables an in-depth retrospective analysis of fall risk factors in the elderly, facilitating the construction of sophisticated statistical models to understand cognitive-motor dual-task performance, postural control, and fall risk.

Current Project
GAITRite Database – retrospective study on risk factors of older adults’ fall
This video might appear in your Reels, showing pedestrians making phone calls while briskly walking and grabbing any random items handed to them. Cognitive-motor interference occurs when a person engages in both a cognitive and a motor task simultaneously (dual-tasking), leading to poorer performance in one or both tasks compared to when they are performed separately (Plummer et al., 2013). For older adults, cognitive-motor dual-tasking can be particularly challenging due to the loss in cognitive and motor integrities associated with aging (Bernard-Demanze et al., 2009; Brustio et al., 2018; López-Otín et al., 2013).
The Basel Mobility Center in Switzerland applied Basel Cognitive-Motor Dual-Task Paradigm (Theill et al., 2011) on patients as support for diagnosis. With clinic and socio-demographical information integrated, a large-scale database with more than ten thousand samples and six hundred parameters was developed.

Bachelor’s or Master’s Thesis (psychology and sport science)
Cognitive-motor interference (CMI) refers to the decrement in performance that occurs when individuals simultaneously engage in a cognitive and a motor task (i.e., dual-tasking), compared to performing each task independently (Plummer et al., 2013). This phenomenon becomes particularly pronounced in older adults due to age-related declines in both cognitive and motor function (Bernard-Demanze et al., 2009; Brustio et al., 2018; López-Otín et al., 2013).
At the Basel Mobility Center in Switzerland, the Basel Cognitive-Motor Dual-Task Paradigm (Theill et al., 2011) has been employed in clinical assessments to aid diagnostic decisions. As a result, a comprehensive database has been compiled, comprising clinical, demographic, and gait-related data from over 10,000 individuals, with more than 600 variables available.
In the context of the GAITRite project, Bachelor’s or Master’s students are invited to conduct a retrospective analysis using this extensive dataset. Students may focus on one or more of the following thematic areas to explore associations with fall risk:
- Socio-demographic factors (e.g., living situation, physical activity levels);
- Clinical factors (e.g., cognitive assessments such as MMSE, medication profiles);
- Physical factors (e.g., use of sensory or walking aids, assessments of muscle strength);
- Gait characteristics (e.g., gait speed, postural sway);
- Cognitive workload and dual-task costs.
Depending on individual interests and level of study, thesis projects may involve exploratory data analysis, statistical modeling (e.g., predicting fall risk), or comparative experimental research. For instance, students may design and conduct laboratory or online experiments to assess CMI in younger populations, enabling age-based comparisons.
Self-initiated topics that align with the scope of the project are highly encouraged. Students will receive support in refining their research questions and analysis strategies based on the available data.
