I’ve just finished reading Wellman & Liu (2004). The scale they developed for measuring children’s progress in their development theory of mind is a great tool with lots of potential. They claim their scale can be used in “research examining the interplay between theory-of-mind understanding and other factors.” (Exactly what I want to do). Thinking of other interactions, I wonder if there’s something like that for measuring number or mathematical knowledge.

I also like Calero, Salles, Semelman, & Sigman (2013) paper on a modified version of Wellman and Liu’s experiment. They developed a computer-based version of the test and validated it with a 6-to8 year old Argentine children. That’s something I could use for my research too.
