Uninostril yoga breathing practices have improved spatial memory scores. There has been no assessment on the effect of high-frequency yoga breathing (HFYB) on working memory and spatial memory scores using the Corsi block-tapping task (CBTT).


The present study was planned to assess the immediate effects of HFYB and breath awareness (BAW) compared to a control session on performance in a CBTT.


Fifteen participants of both sexes with ages between 18 and 24 years (group mean age ± standard deviation, 20.0 ± 1.6 years; 10 females) were recruited for the trial from a university in North India. Each participant was assessed in three sessions conducted on 3 separate days at the same time of the day. The three sessions were (i) HFYB, (ii) BAW, and (iii) quiet sitting (QS). The duration of the intervention was 18 min. The participants were assessed before and after all the three sessions. Repeated-measures-analyses of variance followed by post hoc tests with Bonferroni adjustment were performed to compare data before and after all the three sessions.


BAW resulted in an improvement in backward total scores (P < 0.05) and the backward Corsi span (P < 0.05; one tailed).


The results suggest that BAW improves primary working memory, spatial memory, and spatial attention. HFYB did not cause any change.
