ABSTRACT
Se aplicó una tarea de detección visual del movimiento coherente, confeccionada en el Centro de Neurociencias y Procesamiento de Imágenes y Señales de la Universidad de Oriente, en Santiago de Cuba, mediante la cual se determinó que los escolares disléxicos estudiados podían detectar el movimiento visual, pero cometían muchos errores y omisiones, indicativos de un ligero debilitamiento del proceso de detección visual. También se observaron deficiencias perceptivas en ellos, relacionadas con el incremento de la densidad de los puntos que se movían en los paneles y su disminución porcentual, así como también con el aumento del tiempo de respuesta, reveladores de una reducción de la sensibilidad a la percepción visual del movimiento en estos alumnos con dislexia del desarrollo.
A task of visual detection of the coherent movement, made in the Neurosciences and Processing of Images and Signs Center from Oriente University was applied in Santiago de Cuba, by means of which it was determined that the dyslexic students studied, could detect the visual movement, but they made many mistakes and omissions, indicative of a slight weakening of the visual detection process. Perceptive deficiencies were also observed in them, related with the increment of the density of the points which moved in the panels and their percentage decrease, as well as with the increase of the response time, showing of a reduction of the sensibility to the visual perception of movement in these students with development dyslexia.
ABSTRACT
A presente pesquisa caracterizou-se em determinar a prevalência da dissociação ocular e manual em crianças com dislexia do desenvolvimento em idade escolar comparadas com crianças normais, pertencentes a escolas públicas. Participaram do estudo crianças entre sete e 12 anos. O Grupo I foi constituído por crianças diagnosticadas com dislexia do desenvolvimento (n = 64) e o Grupo II constituído por crianças- padrão na mesma faixa etária (n = 80). Foi aplicada a Bateria Psicomotora. As crianças disléxicas obtiveram escores significativos de prevalência manual esquerda e ocular direita. Tais resultados sugerem que esta falta de especialização da lateralidade pode comprometer a execução motora.
This research was characterized to determine the prevalence of dissociation eye and hand in children with developmental dyslexia at school age compared with normal children from public schools. Study participants were children between seven and 12 years. Group I consisted of children diagnosed with developmental dyslexia (n = 64) and Group II consists of standard children the same age (n = 80). Psychomotor Battery was applied. Dyslexic children scored significant prevalence of left hand and right eye. These results suggest that this lack of expertise of laterality may impair motor execution.
