Study on the differences of Chinese handwriting characteristics among different population / 中华行为医学与脑科学杂志

ABSTRACT

Objective To investigate the differences of handwriting characteristics among different genders,educational backgrounds and ages. Methods The ESP1020 was used to collect 1 474 handwriting samples throughout the country,and the collected handwriting samples were quantized by the self-developed" HCAS" software. The system could automatically extract 36 objective handwriting features,such as the aver-age character area,at the same time,4 subjective handwriting features such as the overall beauty are quanti-fied by the " overall impression evaluation method" . Finally,forty handwriting characteristics data were intro-duced into SPSS23. 0 for statistical analysis. Results There were statistically significant differences in 11 handwriting characteristics between male and female,such as average Chinese characters height ((6. 960± 1. 843) mm,(6. 757±1. 762) mm,t=2. 16,P<0. 05). There were statistically significant differences in 21 handwriting characteristics between the groups with different educational backgrounds,including the average Chinese characters area in primary school and junior high school((52. 175 6± 33. 989 5) mm2 ),in senior high school and technical secondary school(( 64. 320 7 ± 63. 123 5) mm2 ) and in junior college or above ((63. 815 3±58. 147 4)mm2)(t=5. 42,P<0. 01). There were statistically significant differences in 28 hand-writing characteristics in different age groups,such as writing time,pen pressure and Chinese characters area (P<0. 05,P<0. 01). Conclusions Demographic variables such as gender,education background and age have different effects on different aspects of handwriting characteristics.
