She will soon learn how to combine those berninger writing a resume into exquisitely precise gestures aimed at transcribing her ideas while coping with legibility constraints.
When one realizes how early the learning starts, how long it develops, and how complex the simultaneous acquisition of the motor and linguistic codes is, one can intuitively understand that learning how to write has consequences not only on the organization of the brain, but also on the functioning of other skills such as reading.
See Berninger and Chanquoy for a review of research on writing development from the first year of life through adolescence. In this article berninger writing a resume review what has been learned from brain imaging of individuals with acquired writing disorders, for example, due to disease, stroke, or injury and individuals who are still developing and learning to write.
Because writing is a complex process, in this article we focus on current understanding of handwriting and its relationship to other skills. We also feature research studies and dissemination efforts that have involved collaborations between French and American researchers.
Adults 3The overall shape of a word traced on a piece of paper, on a blackboard, or with a toe on the sand is always preserved despite massive changes in the effectors used to produce the movement.
When this memory gets disorganized following a brain lesion, the shaping of the letters becomes difficult for the patients.
This condition is termed apraxic agraphia, and typically results from lesions in specific brain regions. Further investigations are required to refine our understanding of the exact position, and the functional properties and functional specificity of premotor regions in writing.
These findings indicate that the two representational systems, and their graphomotor functions, develop independently.
This raises the intriguing possibility that the motor patterns for writing linguistic items such as letters are implemented in a specific brain region and very finely grained functional specificity present in the motor system. Motor representations of letters may be more stable and more strongly anchored in the precentral regions.
As shown in figure 1, when the brain signal during writing is compared to a situation where the participants simply hold the pen on the tablet, an extensive network encompassing the primary sensorimotor cortex and various sensory and associative regions supporting visual and auditory processing activates.
This activation is due to the fact that writing is not only a finely controlled hand gesture. The respective functions of these regions are not yet fully understood, but the fusiform gyrus was consistently identified by Purcell et al. More generally, a subpart of the left fusiform gyrus is related to orthographic word-form processing e.

Writing to dictation has been contrasted to a situation where the participants were holding the pen on the writing surface without moving.
Writing engages a large number of sensory and motor cortical regions, because the dictated stimulus has to be processed by auditory regions and converted into gestures while the visual feedback is processed online by the occipital regions.
One can notice the strongly left-lateralized activations, related to the control of the right hand by left hemispheric sensorimotor regions.
The 4 brain nodes which activation is consistent among brain imaging studies of handwriting are circled in blue. Modified from Longcamp et al. The cerebellum, which is the hind brain, another important center for writing, is not shown in this representation.
In an fMRI study involving children between 5th and 6th grade, Richards et al. Good writers were more efficient in writing highly practiced letters than poor writers. Interestingly, the premotor and parietal cortices, the cerebellum and the fusiform gyrus were engaged more strongly when the children were writing a new letter pseudoletteras if their activation needs to be higher when the memory of the shape is not stable yet in memory.
However, this was true only in the case of good writers, because the activation in of those regions did not differ between newly taught and highly practiced letters in poor writers. Another important, and related, result was that efficiency in writing was linked to the involvement of a more restricted and focused brain network.
Good writers engaged fewer neural regions to write a newly taught letter than did the poor writers. The component strokes in the novel configuration of the pseudoletter are highly practiced but not in the taught configuration; so the efficiency of production must be related to the overall context or configuration in which those motor strokes are produced.
Conversely, poor writers overactivated the visual system, and extra parietal and cerebellar regions. Finally, good and poor writers differed significantly in activation in left fusiform cortex when writing highly practiced letters.
This individual fusiform activation correlated significantly with behavioral measures of automatic letter writing and expressive orthographic coding.
Multiple regression in which both individual fusiform activation and individual orthographic coding were entered explained significant variance in written composition. Thus, contrary to a popular belief handwriting is not just a motor or movement skill—it also involves written language at the letter form level.
As pointed out by this study, there is also a critical involvement of and interactions between the visual and motor systems in the development of the writing skill, since the efficiency depends both on the focalization of the activation on motor-related brain regions when practicing new shapes and on the fusiform gyrus when writing highly practiced shapes.
In addition, this pattern of brain activity significantly predicts other language skills. We will discuss those two statements in turn in the following sections. In addition, not only the level of activation of certain regions differs between good and poor writers, but also the overall pattern of connectivity of the brain Richards et al.
Letter Recognition and Reading 11In the great majority of clinical observations, alexia, that is the acquired inability to read following a brain lesion, occurs following a lesion of the left occipito-temporal areas fusiform gyrus.
However, deficits in the visual identification of letters can sometimes be associated with inability to write letters Anderson et al.
Conversely, visual and sensorimotor cerebral representations of letter shapes could be somehow coupled. In the case described by Anderson et al.
A first answer was given by Japanese researchers, who showed that several associative and motor areas are both activated when ideographic and syllabic Japanese characters are visually presented and written, and when the subjects are instructed to retrieve kanji ideograms Matsuo et al.In the United States, net neutrality, the principle that Internet service providers treat all data on the Internet the same, and not discriminate, has been an issue of contention between network users and access providers since the s.

Berninger also discusses the benefits of being multilingual by hand. Writing a letter is one of the simple pleasures of life that we have overlooked and sidelined as technology and innovation has paved the way for forms of communication that are very cold, as compared to the warm feeling of a handwritten letter.
