AB We examined if we could improve performance in so-called Stock-Flow Systems (SF-systems). SF-systems are dynamic systems, which consist ofa stock and two flows – the inflow and the outflow. The stock changesdepending on the flows’ patterns. Many persons have problems understandingthese systems (Sterman, 2002). Up to now, only one modification of the flows’representation format led to rather strongly enhanced SF-performance: usingpictograms instead of line graphs (Brockhaus, Arnold, Schwarz, & Sedlmeier,2013). The present experiment analyzed if pictograms led to betterperformance when the SF-task was somewhat changed; this time, we focusedon basic SF-understanding. Additionally, it analyzed, if further modifications ofthe diagram – emphasizing the distinction of the two flows and emphasizingthe calculated difference of inflow minus outflow – could improve SF-performance. Results showed, the effect was smaller, and participants workingon pictograms only solved about 50% or less of the tasks correctly. However,using pictograms improved SF-performance again.
