CARBALLO REINA, Onelia  and  BARCAS TROVAJO, Beatriz. Detection of the global movement direction in students with orthographic disorders. MEDISAN [online]. 2015, vol.19, n.9, pp.1103-1110. ISSN 1029-3019.

A descriptive and prospective study was carried out from January to May, 2014, in order to characterize the detection of the global movement direction in students with orthographic disorders, for which the Gabor patch was used. Two groups of 9-11 years students were selected; one with orthographic disorders and the other one with good academic results, belonging to "Nguyen Van Troi" Primary School in Santiago de Cuba. The results indicated that children of the first group didn't carry out appropriate perceptive inferences of the global movement direction. There were no evidences that the global advantage facilitated the detection of the movement direction; therefore, they made more mistakes when determining the trajectory of the movement for vertical orientations of the grating, on the contrary for the horizontal location where they showed their best performance

Keywords : global movement; Gabor patch; perceptual inference; global advantage; bar orientation.
