Summary
Assessing emotional stress from handwriting is challenging. Spatial writing features altered by stress are indistinguishable from those caused by writing speed.
Area of Science:
- Forensic Science
- Psychology
- Graphology
Background:
- Handwriting analysis is used in various fields, including forensic science and psychology.
- Emotional stress can potentially alter handwriting characteristics.
- Distinguishing stress-induced changes from other factors is crucial for accurate assessment.
Purpose of the Study:
- To determine if emotional stress can be retrospectively identified from handwriting samples.
- To investigate the distinctiveness of stress-related modifications in spatial writing features.
Main Methods:
- Analysis of spatial handwriting features.
- Comparison of handwriting samples produced under emotional stress versus normal conditions.
- Statistical evaluation to differentiate between stress-induced and speed-induced modifications.
Main Results:
- Modifications in spatial writing features due to emotional stress were not clearly distinguishable.
- These stress-related changes overlapped significantly with handwriting characteristics associated with increased writing speed (acceleration).
Conclusions:
- Retrospective assessment of emotional stress solely from handwriting based on spatial features is currently not feasible.
- Further research is needed to identify reliable indicators of emotional stress in handwriting that are independent of writing speed.
