The need to provide more holistic adaptivity to students has brought us to investigate the relationship between learning styles and working memory capacity (WMC). The aim of this investigation is to study the relationship between learning styles and WMC in order to get additional information about the students. This information can be used to make more holistic adaptivity possible by improving the student modelling process of both learning styles and WMC. An experiment with 297 participants was conducted. Findings suggest that relationships from WMC to the active/reflective, the sensing/intuitive, and the visual/verbal learning styles exist, whereas the suggested relationship from WMC to sequential/global learning styles could not be found.
