Graphology and Using It in Cases of Crime

Will be writing more in regards to this in future for this blog and cases.

Graphology is based upon the following basic assertions:

* When we write, the ego is active but it is not always active to the same degree. Its activity waxes and wanes; being at its highest level when an effort has to be made by the writer and at its lowest level when the motion of the writing organ has gained momentum and is driven by it.

* When the action of writing is comparatively difficult, the writer uses those forms of letters which are simpler or more familiar.

* The muscular movements involved in writing are controlled by the central nervous system. The form of the resultant writing movement is modified further by the flexibly assembled coordinative structures in the hand, arm, and shoulder; which follow the principles of dynamical systems. The specific writing organ (mouth, foot, hand, crook of elbow) is irrelevant if it functions normally and is sufficiently adapted to its function.

* The neurophysiological mechanisms which contribute to the written movement are related to conditions within the central nervous system and vary in accordance with them. The written strokes, therefore, reflect both transitory and long term changes in the central nervous system such as Parkinson's disease, or alcohol usage.

* The movements and corresponding levels of muscular tension in writing are mostly outside of conscious control and subject to the ideomotor effect. Emotion, mental state, and biomechanical factors such as muscle stiffness and elasticity are reflected in a person's handwriting.

* One must examine the handwriting or drawing movements by considering them as movements organized by the central nervous system and produced under biomechanical and dynamical constraints. Given these considerations, graphologists proceed to evaluate the pattern, form, movement, rhythm, quality, and consistency of the graphic stroke in terms of psychological interpretations. Such interpretations vary according to the graphological theory applied by the analyst.

* Most schools of thought in graphology concur that a single graphological element can be a component of many different clusters, with each cluster having a different psychological interpretation. The significance of the cluster can be assessed accurately by tracing each component of the cluster back to their origins and adapting the meaning of the latter to the conditions of the milieu in which the form appears.
