Gómez-Velázquez Maribel Peró-Cebollero Psicología reading Spelling BOLD signal visual word recognition functional Magnetic Resonance Imaging Background: In this paper we studied the functional neural substrates underlying the performance of homophonic spelling error detecting tasksincluding frequent and infrequent Spanish words- through functional Magnetic Resonance Imaging (fMRI) procedure in subjects with low orthographic performance. Method: A block design was used to administer 2 visual tasks, with 2 experimental conditions each, to 8 healthy participants with low orthographic performance. In both tasks correct and misspelled Spanish words sequentially appeared. Participants were instructed to detect orthographic errors in one task, as well as the presence of 1 specific vowel in the other. Image data were obtained from 32 axial contiguous slices and repetition time of 3 seconds. Results: Significant bilateral activations were found, especially in medial temporal areas during the orthographic error recognition task performance, whereas upper right and left frontal regions were significantly activated while detecting a specific vowel. Conclusions: These data are consistent with the literature and suggest an association between orthographic processing and hyperactivation of bilateral cerebral areas in subjects with low orthographic skills, probably due to compensatory mechanisms. 2014 artículo científico 0066-5126 https://www.redalyc.org/articulo.oa?id=97036176005 en http://www.redalyc.org/revista.oa?id=970 Anuario de Psicología application/pdf Universitat de Barcelona Anuario de Psicología (España) Num.3 Vol.44 |
