Lilly Roth is a doctoral candidate in the "Diagnostics and Cognitive Neuropsychology" research group. She completed her Bachelor's and Master's degrees in Psychology at the University of Tübingen, where she also worked as a statistics tutor during her studies. Early on, she developed an interest in data analysis, research methodology, and open science practices. Since 2021, she has been conducting research in the field of numerical cognition. As part of the DFG-funded research project e-SNARC, she investigates spatial mental representations of numbers in large-scale online studies. Her research focuses on the SNARC effect ("Spatial Numerical Associations of Response Codes"), which describes the association of small numbers with the left and large numbers with the right. Lilly Roth’s work provides insights into how automatic, task-dependent, culture-dependent, flexible, and temporally stable spatial mental representations of numbers are.
Beyond the SNARC effect, Lilly Roth has two additional research interests. First, she studies mathematical word problems, examining aspects such as the timing of number processing using eye tracking and the impact of different pronouns on elementary school children's performance. Second, she investigates the validity of generalizing from samples to individuals and from individuals tested in single sessions to the temporal stability of cognitive phenomena.
Beyond her research activities, Lilly Roth has contributed to organizing two workshops ("Promoting transparency & replicability in research" in Tübingen in 2022, as a co-organizer, and "Relations between space, language, and numbers" in Tübingen in 2024, as a main organizer). She is currently actively involved in organizing the TeaP ("Tagung experimentell arbeitender Psycholog:innen" in Tübingen in 2026).
