Summary
This study found no link between handwriting characteristics like line slope and extraversion. Handwriting analysis is not a valid measure of personality traits such as extraversion.
Area of Science:
- Psychology
- Graphology
- Personality Psychology
Background:
- Graphology claims handwriting reflects personality traits.
- Extraversion is a key personality dimension.
- The scientific validity of graphological claims requires empirical investigation.
Purpose of the Study:
- To investigate the validity of handwriting analysis as a measure of extraversion.
- To examine the relationship between specific handwriting features and extraversion scores.
Main Methods:
- Fifty-eight tertiary students participated.
- Handwriting samples were analyzed for line slope, letter slant, and letter width.
- Extraversion was assessed using the Eysenck Personality Inventory.
Main Results:
- No significant correlations were found between handwriting measures (line slope, letter slant, letter width) and extraversion.
- No significant intercorrelations were observed among the handwriting measures themselves.
Conclusions:
- The study's findings do not support the hypothesis that handwriting characteristics are valid indicators of extraversion.
- Empirical evidence does not substantiate graphology's claims regarding the measurement of extraversion through handwriting analysis.
