The detection of specific factors of the developmental dyslexia at an early stage, and the identification of the role of those factors responsible for its manifestation, is a fundamental area of study on dyslexia in the recent literature. The objective of the present study is to clarify that dysfunctions in the following specific domains contribute in a causal model to the occurrence of dyslexia at an early stage: phonological awareness, psychomotor ability (body shape, spatio-temporal orientation, grapho-motor ability and laterality), perception, memory, attention, prereading and prewriting skills. The results of three studies, --carried out in Greece--which revealed the above factors as main predictors of the early onset of Specific Developmental Dyslexia (SDD) and confirmed the importance of intervention methods to it, led us to the construction of the proposed, causal model. The findings of these three studies converge on the perspective that the understanding, diagnosis and treatment of dysfunctions in the above domains, from preschool age, enable the early and reliable prevention of future difficulties in the learning process of children.
