Abstract Some studies have indicated that a relaxation and/or meditation session could affect inhibitory control, while other studies have not found such an effect. Method: A total of 60 students aged between 16-18 years participated in the study, randomly distributed into two groups, according to the experimental (relaxation session) and the control (listening to neutral material) condition. Results: No significant improvements were found in the experimental group compared to the control group in Resistance to Interference. Conclusions: These results suggest that some prior relaxation practice might be necessary for a short relaxation session to have immediate benefits in inhibitory control or/and that the relaxation session should last longer.
