**6. Methodology**

The *PIC*, or *Prueba de Imaginación Creativa Niños* [49], was applied to count creativity for the experimental group (as well as the control group). The *PIC* may be translated as the 'Test of Creative Imagination in Children'. Generally, the *PIC* may be defined as a test of divergent thinking that evaluates creativity by examining how individuals use creative imagination in their creative representations. There are three versions of the *PIC*, for the levels of children *PIC-N*, adolescents *PIC-J,* and adults *PIC-A,* respectively, but all three versions have a similar structure of factorial measure for both verbal creativity and visual or graphic creativity.

Its application can be either individual or collective; in our case, the *PIC* was applied to participants individually. It also measures a 'general' creativity index for each participant. The scope of the experiment was restricted to school children between the third and sixth year of their primary education (with ages between 8 to 12 years). In terms of duration, the application could be variable, although for our experiment, a time-frame of approximately 40 min was chosen. For this duration, the *PIC* could be used to measure things like the ability to: (a) Formulate hypotheses (Exercise 1), (b) to think in an unconventional way (Exercise 2), (c) to exploit imagination and fantasy (Exercise 3), and (d) to employ, specifically, the graphic or imagistic imagination (Exercise 4). Results for the *PIC* are expressed in percentile for each variable studied and for each course of activity. Finally, we need to say that the materials for the test application was comprised of a test manual, an exercise copy, and a correction booklet.
