A standardized database of Chinese emotional short videos based on age and gender differences

Fig 1. The valence scores of each category of emotion-inducing short videos among participants with different ages. Statistical significance: *p < 0.05, **p < 0.01, ***p < 0.001. Unless marked with the asterisk, no significant differences between these groups were found.

Fig 2. The valence scores of each category of emotion-inducing short videos between male and female. Statistical significance: *p < 0.05, **p < 0.01, ***p < 0.001. Unless marked with the asterisk, no significant differences between these groups were found.

Fig 3. The valence scores of each category of emotion-inducing short videos among participants with different ages. A: Male. B: Female. Statistical significance: *p < 0.05, **p < 0.01, ***p < 0.001. Unless marked with the asterisk, no significant differences between these groups were found.

Fig 4. The valence scores of each category of emotion-inducing short videos between male and female. A: Age = 20–24. B: Age = 25–29. C: Age = 30–34. Statistical significance: *p < 0.05, **p < 0.01, ***p < 0.001. Unless marked with the asterisk, no significant differences between these groups were found.

Fig 5. The arousal scores of each category of emotion-inducing short videos among participants with different ages. Statistical significance: *p < 0.05, **p < 0.01, ***p < 0.001. Unless marked with the asterisk, no significant differences between these groups were found.

Fig 6. The arousal scores of each category of emotion-inducing short videos between male and female. Statistical significance: *p < 0.05, **p < 0.01, ***p < 0.001. Unless marked with the asterisk, no significant differences between these groups were found.

Fig 7. The arousal scores of each category of emotion-inducing short videos among participants with different ages. A: Male. B: Female. Statistical significance: *p < 0.05, **p < 0.01, ***p < 0.001. Unless marked with the asterisk, no significant differences between these groups were found.

Fig 8. The arousal scores of each category of emotion-inducing short videos between male and female. A: Age = 20–24. B: Age = 25–29. C: Age = 30–34. Statistical significance: *p < 0.05, **p < 0.01, ***p < 0.001. Unless marked with the asterisk, no significant differences between these groups were found.
