The ancient Indian yoga text, Hatha Yoga Pradipika, describes six cleansing techniques. The objective of cleansing techniques is to purify and prepare the body for the practice of yoga postures, breath regulation, and meditation. Yogic visual concentration technique (trataka) is one of these techniques. A previous study showed an increase in critical flicker fusion (CFF) following yogic visual concentration (trataka). The present study planned to assess the immediate effect of trataka on cognitive performance using the Stroop color-word test. Performance on the Stroop color-word test was assessed in 30 healthy male volunteers with ages ranging from 18 years to 31 years old (22.57 +/- 3.65 years). The participants were tested before and after yogic visual concentration (trataka) and during a control session on two separate days. There was a significant improvement in performance on the Stroop color-word test after trataka compared to the control session [repeated measures analysis of variance (RM ANOVA) with Bonferroni adjustment; p < 0.001]. Performance on the Stroop color-word test was better after trataka compared to the control session suggesting that the trataka technique increased the selective attention, cognitive flexibility, and response inhibition.
