Materials for the article "A Protracted Sensitive Period Regulates the Development of Crossmodal Sound-Shape Associations in Humans".

Format:

3D objects (Stimulus pairs A and C) are in STL format and can be opened in most CAD software (a free and open-source CAD software is FreeCAD, available at www.freecadweb.org). The authors used the software Cura and printed the stimuli with an Ultimaker 2 3D printer. The stimuli can be verified/viewed at a web STL viewer like www.viewstl.com (MIT-licensed).

2/2.5D forms (Stimulus pairs B and E) are in svg and pdf formats which can be used with a compatible laser cutter/printer to produce the stimuli. For laser cutting the authors used the VisiCut sotware (visicut.org).
