The aim of this study was to analyze the effects of dramatization when expressing and recognizing emotions. The study was carried out with 45 male and female primary school pupils aged 10 and 11 divided into two group: experimental, 23 pupils; and control, 22 pupils. Data collection was undertaken using observation scales created ad hoc in line with research objectives, and administered before and after an educational intervention based on dramatization in the case of the experimental group. No treatment was given to the control group. The intervention program for the experimental group consisted of six one-hour sessions in which drama exercises tackled recognition and expression of emotions. The results evidenced a significant improvement in the ability to recognize and express emotions of those pupils who underwent the intervention.
