The Psycho-linguistic Effects of Yoga: A Lexical Analysis of Shifts in Positivity, Agency, and Creativity

INTRODUCTION: Yoga is understood in the scientific community as a powerful de-stressor. Reduced stress has been linked to improved mood, increased agency, and enhanced creativity. OBJECTIVE: This study investigates these potential psychological effects of yoga by comparing two lexical data sets, composed of nearly 3000 words collected before and after yoga classes. METHODS: Each word is scored along three dimensions: positivity, agency, and creativity. Positivity is calculated using SentiWords Sentiment Dictionary 1.0; agency is determined by grammatical categorization; and creativity is viewed as a function of the set distribution. RESULTS: Analysis reveals a shift toward more positive and less agentful self-reporting after practice. No significant difference is found in creativity. CONCLUSION: This study provides insight into how yoga alters thought processes and affects the mental health of practitioners.
