Mathematical modelling of handwriting analysis and its computer-aided implementation
The only practical way to better understand the processes of writing and to analyse its outcomes (personal handwriting) is to properly model the handwriting. That is essential as well for the validation of the handwriting analysis. Formalisation ensures objectivity, reliability and reproducibility of experiments and studies.
Adaptation of new achievements in neuropsychology to handwriting analysis
Neuropsychology allows a better understanding of the process of handwriting. The analysis of that kind of information influences both the practical models and the basic concept which signals: “Handwriting is Brain Writing”. In this context, we are mainly dealing with analytical work.
Computer-aided handwriting analysis
Computer-aided handwriting analysis includes programs for the image analysis of scanned handwriting samples and the automatic evaluation of handwriting signs. It covers on-line digital tools (digitizers and other sensors), and models for computer-aided evaluation of manually analysed handwriting samples. We are evaluating and using such tools in our projects.
Handwriting psychology validation
Validation is essential for every psychological assessment method. Together with objectivity and reliability, it ensures that the method correctly and adequately evaluates the psychological characteristics of a person. In the related studies, we compare the results of the handwriting analysis with other tests that are well validated and well established.
Most of the validation projects we have been doing with our international partners in the framework of the interdisciplinary research team (www.ivha.info).
Modern tendencies of the handwriting and adaptation of analysis methods
Like all other means of communication the habits with respect to handwriting have also considerably changed. Digitalisation has had a great influence on handwriting. However, handwriting remains one of the basic skills. The major rules, models and methods of handwriting analysis have been formed many years ago. They should be revised and adapted. With that intention in mind, we are undertaking multiple statistical evaluations and analytical analyses in order to formally expose the modern trends. This information allows the adaptation of traditional methods and highlights new regularities.
Integration models of handwriting analysis with other tests
The use of a single psychological assessment method does not ensure the required reliability. A formalised handwriting analysis makes it possible to integrate the instrument with other techniques (projective and questionnaires). The integration is based on the output of computer-aided handwriting analysis and computer implementations of additional techniques. The obtained data provides a database and corresponding programs.
Data quality and methods of its optimisation
The basis for any type of psychological experiment is the underlying data. The quality of the data is crucial for the success of the research. The dangerous trend of using simple statistical methods of correlation leads to erroneous conclusions and reduces confidence in the results. Therefore, we pay great attention to the quality of our research data. We have been developing procedures and methods of evaluation in order to ensure the quality of the data. This includes special statistical and ad-hoc methods.
