A continuous measure of relationship closeness inspired by the Inclusion of Other in the Self Scale was designed using Java. This new measure allows for closeness to be assessed on a continuous scale of zero to 100, with output values corresponding to the degree of overlap and distance between the objects in the applet. In addition, the applet includes options to enhance its flexibility and usefulness in research applications. In particular, the behavior of the applet, and properties of objects included in it, can be customized. The construction of the applet is described, and methodological and theoretical considerations regarding this new measure are discussed.
