Cognitive effectiveness of conceptual modeling languages: Examining professional modelers

Research on improving the cognitive effectiveness of conceptual modeling languages visual notations often lacks empirical consideration of the people and modeling tasks involved. Such consideration can generate insight into cognitive requirements set by different modeling tasks. In this position paper we propose an empirical research design for gaining a deeper understanding of the difference between the cognitive requirements of specific modeling tasks so that modeling notations can be improved, based on empirically grounded needs of professionals.
