The conducive design of digital learning materials requires essential preliminary considerations, particularly referring to limitations in learners’ cognitive resources. These should not be overloaded due to the variety of occupied modalities and interactive features. I inspected related dynamics from a temporal perspective with behavioral experiments and computational models. A potential application of the emerging algorithmic framework consists in the field of adaptive educational assistants that offer tailored instructional support based on the detected level of cognitive load.
Continuous cognitive load assessment (2015 – 2017)
A prominent theory in the field of educational media, the Cognitive Load Theory, postulates different facets of cognitive load related to selected aspects of the learning situation and the learning process. Within a fruitful collaboration with the chair of Media Informatics at the TU Chemnitz, I examined the interplay between these facets in abstract learning tasks with particular focus on process-related changes across a learning task. On methodological accounts, I used a variety of approaches, ranging from experimentally obtained performance measures, paralinguistic speech indices, and psychophysiological parameters. The obtained findings indicate decreasing levels of cognitive load with increasing progress in knowledge acquisition.
Predicting neural response patterns (2016 – present)
To inspect related cognitive processes in more detail, I developed cognitive models with the cognitive architecture ACT-R. I further generated simulated fMRI predictions to gain insight into emerging dynamics on a neural level. This approach leverages the correspondence of ACT-R’s modular structure with predefined brain regions. I currently continue and extend this line of research in collaboration with the Cognitive Modeling Group at the University of Groningen in the direction of model-based cognitive neuroscience to validate and strengthen the existing findings.
