As noted in the last bibliography of Human Problem Solving compiled by Joachim Funke and reported in the Journal of Problem Solving in 2013, problem solving as a concept and as a research issue has been gaining more interest than ever before. Now in 2016, we can see that publications on the topic further increased to around 1,800 per year in both 2013 and 2014. The papers in this special issue come from two areas of problem solving research, mathematical and creative problem solving, which represent a good part of this growth trend. With this special issue, the journal has closed its first decade. We look forward to another decade of growth in research on important questions about the mental mechanisms underlying this cognitive ability.
