CPACT Research: Computational Psycholinguistic Analysis of Czech Text

CPACT (Computational Psycholinguistic Analysis of Czech Text) was a three-year research project (2016–2018) devoted to the study of human communication. The research aimed to understand the relations between a person’s personality and the words they use. Why do people use different sentences, words, or phrases when communicating about the same topic? By combining advanced computational methods with modern psychodiagnostics, the unique phenomenon of human communication can be studied from an entirely new perspective.

The CPACT research focused on studying the relationships between one’s personality and the words the person uses; especially on the level of relationships between linguistic characteristics of written and spoken texts and results from psychological tests in self and other report variants. For these ends, a three-module plan has been estabilished. First project module includes quota sample of participants, further referred to as P200 (n=200), consisting of pairs of close people was selected. The sample was quota representative of the Czech population according to the data for 2015 of the Czech Statistical Office in the categories gender, age and education. During individual research sessions, the participants gave their personal information, produced four written texts with different contents, took part in two recorded semi-structured interviews and filled in two batteries of psychological tests: self-report and other report on the other person in the pair. The data were collected in a controlled environment, following an in advance given scenario. The second module (the so-called P20+) worked with a sample of other 72 people, clinically diagnosed with a specific mental disorder (anxiety and/or depression), who produced the total of four types of written texts and filled in an adapted test battery.

All the textual data were analysed computationally (quantitatively) in 26 basic linguistic categories (195 variables), 31 combined linguistic variables, 9 proportional linguistic variables and 8 variables–indexes, i.e. the total of 243 variables – unique text parameters. Processing of psychological data in the quota sample was based on the results from 45 questionnaire scales (a battery of 12 tests) in the self-report variant and 36 scales (a battery of 9 tests) in the other report variant, or of 25 scales (6 tests) in the complementary sample (P20+). The reported research included a third module (the so-called P2) that was based on subjective assessment of research texts by trained assessors whose outputs were compared with the above presented data.

The CPACT project was realised by the Faculty of Education, University of South Bohemia (Pedagogicka fakulta Jihočeské univerzity v Českých Budějovicích) in 2016-2018, and is funded by a grant from the Czech Science Foundation (GAČR, grant no. 16-19087S). The project team comprises experts from four academic institutions, including University of South Bohemia, Masaryk University, University of Hradec Králové, and Charles University.

Emotionalty in Handwriting, Interpersonal Characteristics in Handwriting

The research “Emotionality in Handwriting, Interpersonal Characteristics in Handwriting” (2010–2013) is focused on the relations among the writer’s handwriting, selected personality characteristics and his/her emotional experience, using contemporary graphometric methods.

The topic in question appears to be quite a rare one, with little psychological research conducted in the field. That is because most research studies published up to date have dealt with other, related, areas of the study of handwriting, such as graphology, i.e. the psychology of handwriting. Therefore, their scope of interest and character differs in many ways, in particular their lack of scientific approach to handwriting and its quantitative analysis. The thesis therefore represents an utterly new approach and research design, as the study presented – EH-IPCH (Emotionality in Handwriting, Interpersonal Characteristics in Handwriting) – makes us of an alternative approach used for a scientific description of handwriting, that of computer comparative graphometry. During the relatively demanding research, various types of data were compared, such as handwriting characteristics analysed using graphometric software and personality questionnaire data. Furthermore, the data was collected both in normal / neutral setting and in an experimental situation in which the writers were subjected to emotional induction procedure.

Research findings point out to various correlations between personality characteristics and graphometric parameters. Furthermore, a subtle correlation was found between the emotional experience of a situation and a subsequent modification of handwriting. In addition, the set-up of the graphometric analysis, as well as the sample selection, seem to influence the success of the procedure, and thus the psychodiagnostic potential of the graphometric method. In conclusion, research findings suggest that the study of handwriting, as a source of psychologically relevant information, has a significant potential and may prove to be of great interest for further academic research.
