Parkinsonian Patients Reduce Their Stroke Size with Increased Processing Demands

Parkinson's disease (PD) patients often show reductions in writing size (micrographia) as the length of the text they produce increases. The cause for these reductions in stroke size are not well understood. Reductions in stroke size could be associated with either concurrent processing demands that result from the coordination and control of fingers, wrist, and arm during writing and the processing of future words or increased extension of the wrist joint as the execution of the writing progresses to the right across the page, resulting in increased stiffness in the pen-limb system. Parkinson's patients and elderly controls wrote phrases of different lengths with target patterns in various serial positions. When the number of words to be written increased, PD patients reduced their stroke size of the initial target pattern, while the elderly controls did not reduce their stroke size. There was no systematic change in stroke size of the second pattern as function of serial position. This result suggests that PD patients reduce the size of their handwriting strokes when concurrent processing load increases.     

Using self-evaluation to improve difficult-to-read handwriting of secondary students

We used delayed multiple-baseline and multiple-probe techniques to assess the effects of self-evaluation training on the legibility of cursive handwriting. Five secondary special education students with difficult-to-read handwriting served as participants. All participants improved the legibility of their handwriting during self-evaluation training. A systematic withdrawal of the training package demonstrated maintenance of treatment effects. For the most part, the students' handwriting remained at least 90% legible to judges following the systematic withdrawal of the self-evaluation training.     

快速书写条件下硬笔笔迹变量与认知及个性特征的关系

以圆珠笔为书写工具．北京市某中学高一学生为被试,有效数据169人．探讨了在快速抄写条件下,笔迹书写特征与认知及个性的关系：18个笔迹变量可抽取笔压、结构、特征、字体和空间五个反映字的书写特征的因素;书写特征与认知因素间,横、竖笔压与概念形成速度。整篇压与视力追踪、字位与眼手协调相关显著;横笔压与16PF测验中的畏缩退怯——冒险敢为有正相关;竖笔压与艾森克个性因素的N有高相关。     

儿童汉字练习:纸笔手写与键盘拼音输入的效果比较

在学校情境下,采用纸笔手写和键盘拼音输入练习汉字的实验任务,比较了75名小学六年级儿童在两种练习方式下的汉字学习及复习效果,并进行了保持效果的追踪。结果发现,纸笔手写和键盘拼音输入对儿童的汉字复习具有同等积极作用,在再认选择和回忆书写上效果均相当;对儿童的汉字学习积极作用不一致:在再认选择上两者积极效果相当,但在回忆书写上,手写明显优于拼音输入。另外,经纸笔手写和键盘拼音输入复习和学习的汉字,其记忆保持随时间变化的趋势一致。以上结果说明了对具有书面语言经验的儿童,拼音输入与手写都有助于形成和巩固汉字在心理词典中的义音形联结,但手写动作更有利于汉字从正字法代码向书写动作程序的转换;"提笔忘字"现象可能是正字法遗忘的结果,并非由使用拼音输入法造成。     

中文书写者字迹识别的眼动研究

采用眼动技术,以不同整体书写风格的字迹为实验材料,探讨中文字迹识别的眼动模式。实验结果显示：随着整体书写风格一致性的变化,被试识别不同书写者中文字迹的反应时、注视次数,眼跳次数,兴趣区数及落入兴趣区的比率均表现出显著性差异。结论：（1）识别中文字迹依赖字迹整体书写风格;（2）中文字迹识别模式：在识别字迹时,优先采用字迹整体书写风格识别不同的字迹;（3）中文字迹识别属于图像识别加工。     

笔迹与人格关系研究的回顾及评价

西方心理学者对笔相学家的笔迹分析提出质疑,研究表明需要我们重新考虑笔迹分析的适用性,而其利用因素分析技术对笔迹与人格关系的大量研究发现,笔迹特征与EPQ中的E因素、N因素相关显著。我国古代丰富的笔迹学思想和当代笔相学家的实践经验为我们从心理学角度研究笔迹与人格之间的关系,提供了宝贵的资料,但我们在这一领域运用心理学方法的研究还刚刚起步。目前国内外心理学者在研究取向、笔迹特征选择和研究目的上还存在一定局限,对此加深认识,将会对我们具有重要的借鉴意义。
