生理因素和环境因素对双生子笔迹影响的研究

目的 研究双生子由于受共同生理因素影响,教育和环境影响对笔迹特征影响的差异.方法 收集了80对双生子的笔迹,采用统计分析的方法进行研究.结果 书写水平、字的大小、字形、字行间距、书写速度特征受生理因素的影响较大,环境因素对竖长、撇长、转折角度、页边、错别字、笔画变异、笔画形态、搭配比例、写法、笔顺特征的影响更大.结论 生理因素和环境因素对笔迹的影响并不是彼此完全独立的,二者往往通过复杂的方式交互作用影响笔迹,一级亲属笔迹鉴定中应注意的选择特殊性强的笔迹特征全面比较.

Influence of physiological factors and environment factors on handwriting of twin

The handwriting samples of 80 pairs of twins were collected and analyzed with statistical method. The results showed that the writing level, word size, word shape, line space and writing speed are influenced largely by physiology, and the vertical long, turning angle, margin, typos, stroke, the proportion of stroke and the order of stroke are influenced largely by the environment. The author suggested that, in first-degree relatives of handwriting identification, attention should be paid to the special and strong characteristics of handwriting.
