Purpose: This study aimed to investigate whether birth experience affects short-term memory (1,2-back task) by examining parturient and non-parturient women.
Methods: A total of 31 women were enrolled in this study, of which 16 were parturient women who had given birth within the past 2 years (mean age: 33.9±2.2 years) and 15 were non-parturient (mean age: 31.4±2.1 years). The mean age did not significantly differ between the two groups, so the effects of age were eliminated. To match the level of education between the two groups, college graduation was an inclusion criterion. A 1,2-back task consisting of six alphabets from A-F was created using the SuperLab software. For each task, there were 100 stimuli (alphabets) and 30 answers. The participants practiced the task prior to the main experiment to ensure that they adequately understood the procedure.
Results: The correct answer rates in the 1-back and 2-back tasks were 93.56±22.23% and 76.89±21.98%, respectively, in the non-parturient group and 95±10.04% and 80.83±13.67%, respectively, in the parturient group. The reaction time in the 1-back and 2-back tasks were 650.57±173.77 ms and 736.77±138.35 ms, respectively, in the non-parturient group and 621.91±81.90 ms and 737.5±195.99 ms, respectively, in the parturient group. There were no significant differences in the answer rates between the two groups, suggesting that parturition did not have a significant impact on the 1,2-back task performance.
Conclusion: Birth experience does not significantly impair cognitive function. However, the findings of this pilot study are not highly reliable because of the limitations of the small sample size, degree of load, various types of working memory, and impact of hormones.
