Sci Am looks Toward an Imagination Science.
At the link are a video and PDF of the results of a Neuroscience Imagination Retreat.
The past decade has seen an explosion of research into the psychology and neuroscience of imagination, with rapidly evolving literatures on topics ranging from mind-wandering, daydreaming, mental simulation, theory of mind, and creative problem solving. Despite considerable progress, however, several fundamental questions remain: What is imagination, and how do we measure it? Is imagination a fixed ability, or can it be enhanced through targeted intervention?
Sci Am also discusses how they make infographics, this one on pregnancy in progress.
