Executive functions and play.

Executive functions and play have been researched separately over the last few decades. Only recently has the association between the two constructs received more attention. Thus, a Special Issue on this association is timely. The six empirical studies of the Special Issue applied various types of play (e.g., dramatic play or physical play) in their research. Children's executive functions were also measured with a variety of tasks. The wide variability of the studies was a learning point, especially given the cultural connotation of executive function measures. All the studies of the Special Issue were conducted in WEIRD (Western, Educated, Industrialized, Rich, and Democratic) countries raising the issue of generalizability. We discuss future directions of the research on executive functions and play hoping for longitudinal studies on the association between these constructs in the future.
