Слайд 1


Dysgraphia Component of the Functional System Visual image of letter Symptoms of disturbances and compensations Substitutions of visually similar letters Compensation – the use of kinaesthetic analysis of graphic movements The role in writing Visual analysis of details in letters Brain area Visual cortex (occipital lobe) Brain mechanism Processing of visual information

Слайд 2


Dysgraphia Component of the Functional System Visuospatial image of letter Symptoms of disturbances and compensations Mirror writing Problems in vertical and horizontal orientation of elements Problems of holding the line Substitution of spatial details of letters (v/y) Ignoring a part of the visual field Difficulties in finding the beginning of the line when writing The role in writing Visual analysis of letters which have only visuospatial differences Brain area Posterior-parietal associative cortex (parietal lobe) Brain mechanism Processing of visuospatial information

Dysgraphia Component of the Functional System Motor component Afferent part Symptoms of disturbances and compensations Disturbance of fine motor in writing Clumsy writing Compensation – big letters The role in writing Kinaesthetic analysis of graphic movements (motor schema corresponding to the image of the letter). Brain area Somatosensory cortex (hand/wrist area) Brain mechanism Processing of kinaesthetic information

Слайд 4


Dysgraphia Component of the Functional System Motor component Efferent part Symptoms of disturbances and compensations Perseverations of elements in letters, letters, syllables, words Disturbances of the sequence of letters in the word Fusing separate words Compensation – writing in printed letters The role in writing Kinetic (sequential) organization of movements in writing Easiness of transition from one element of letter to another, from one letter to another. Brain area Premotor cortex (Supplementary motor cortex - SMA) Brain mechanism Kinetic mechanism

Dysgraphia Component of the Functional System Control in writing Symptoms of disturbances and compensations “Stupid” errors Omission of vowels in stressed position Lack of capitalization and punctuation The role in writing Planning, initiation and control in writing Control in using punctuation and orthographic rules. Brain area Prefrontal cortex (Third functional unit - unit of programing, regulation and control) Brain mechanism Executive mechanism
