Percepção espacial, Percepção de forma, Cognição, Modalidades sensoriaisResumo
A cognição espacial corresponde à capacidade de um indivíduo de perceber as relações espaciais entre os objetos bem como de lidar com as noções de profundidade, solidez e distância. Essa capacidade cognitiva está intimamente correlacionada com a percepção espacial, a qual pode ser entendida como o resultado final da organização e integração de diversos estímulos sensoriais de maneira a fornecer à consciência um panorama geral acerca das formas do meio externo entre si e suas relações espaciais. Realizamos, nesse artigo, um resumo das diversas vias sensoriais (visual, tátil, proprioceptiva, auditiva e vestibular) capazes de fornecer elementos para o desenvolvimento da cognição espacial. Ao longo dessa exposição procuraremos elucidar os mecanismos psicológicos inerentes a esse processo bem como suas respectivas bases neurofisiológicas. Será também abordada a importância da Área de Associação Heteromodal do Córtex Parietal Posterior para a cognição espacial. Por último será realizada uma breve discussão acerca das diferentes síndromes que envolvem alguma forma de déficit da cognição espacial
