Handwriting

Handwriting refers to a person's writing created with a writing utensil such as a pen or pencil. The term encompasses both printing and cursive styles and is separate from formal calligraphy or typeface. It is, in essence, a visible form of a person's voice, including pitch and tone.

Because each person's handwriting is unique, it can be used to verify a document's writer, and the deterioration of a person's handwriting is also a symptom or result of certain diseases.

Uniqueness of handwriting

Each person has there own unique style of handwriting, whether it is normal handwriting or signature. Even identical twins who share appearance and genetics don't have the same handwriting. They are like the finger prints (people might be able to copy it, but never write it in the identical way). The place where one grows up and the first language one learns melt together with the different distribution of force and ways of shaping words to create a unique style of handwriting for each person. [1]

Characteristics of handwriting include:

  • specific shape of letters, e.g. their roundness or sharpness
  • regular or irregular spacing between letters
  • the slope of the letters
  • the rhythmic repetition of the elements or arrhythmia
  • the pressure to the paper
  • the average size of letters
  • the thickness of letters

Medical conditions

Children with ADHD have been found to have less legible handwriting, make more spelling errors, more insertions and/or deletions of letters and more corrections. The letters tend to be larger with wide variability of letters, letter spacing, word spacing, and the alignment of letters on the baseline. Variability of handwriting increases with longer texts. Fluency of the movement is normal, but children with ADHD made slower movements during the handwriting task and hold the pen longer in the air between movements especially when they had to write complex letters, implying that planning the movement may take longer. ADHD children have difficulty parameterising movements in a consistent way. This has been explained with motor skill impairment either due to lack of attention or lack of inhibition. To anticipate a change of direction between strokes constant visual attention is essential. with inattention changes will occur too late, resulting in higher letters and poor alignment of letters on the baseline. The influence of medication on the quality of handwriting is not clear.[2]

Uses of handwriting samples

Because handwriting is relatively stable, a change in the handwriting can be indicative of the nervousness or intoxication of the writer.

A sample of a person's writing can be compared to that of a written document to determine and authenticate the written document's writer; if the writing styles match, it is likely that one person wrote both documents.

Graphology

Graphology is the pseudoscientific[3][4][5] study and analysis of handwriting in relation to human psychology. Graphology is primarily used as a recruiting tool in the applicant screening process for predicting personality traits and job performance, despite research showing consistently negative results for these uses.[6][7][8]
