Laterality cross: false disorder

Writing with the right or left hand is a hereditary genetic factor, although it can be determined by environmental and educational factors. Although being left-handed can complicate certain learning very occasionally, it is not demonstrated that the prevalence of school difficulties is different between right-handed and left-handed .

If the dominance of the hand, leg, eye, ear ... does not fall on the same side is spoken of crossed laterality. This fact, however, does not have to involve a pathology or learning problems, that is, the presence of a homogeneous cross-laterality (for example, being always left-handed and right-handed) is an evolutionary fact that is always normal. It is important that the establishment of the lateral dominance organization be clearly defined around 5 years. If a non-homogeneous crossed laterality is not defined and observed, that is to say, using non-preferentially any of both hands, eyes or feet in different activities and continuously, it is a sign that the neurological development is not mature enough and may have, in some cases, consequences, for example, in the learning of literacy.

Cross laterality: assess its association with other disorders

It must be borne in mind that a delay in the organization of laterality with the presence of a non-homogeneous crossed laterality will never be isolated , but usually associated with other disorders such as, for example, attention difficulties or other difficulties in neuropsychological maturity or psychomotor. Based on this, it is important to emphasize that in these cases it is very common that the fundamental cause of learning difficulties is not inhomogeneous cross-laterality but other associated dissociative variables such as the attention deficit disorder itself.
