Enviar artigo via e-mail O ritmo e a sua relação com som: a influência do contexto sensorial na precisão da percepção e produção de ritmo
Resumo
O presente artigo apresenta os resultados finais de uma pesquisa neurocientífica realizada no Programa de Pós-Graduação em Neurociências e Comportamento da Universidade de São Paulo. Partindo da hipótese de que a modalidade sensorial das informações temporais pode influenciar diretamente o funcionamento dos relógios internos, foi desenvolvida uma pesquisa cujo objetivo central foi verificar se a precisão da sincronização das batidas sucessivas do dedo a estímulos externos seria alterada em função das modalidades sensoriais dos eventos temporais. Para tanto, foram realizados dois experimentos psicofísicos, cujos resultados confirmaram a hipótese de que a percepção de ritmo é mais fortemente ligada ao sistema auditivo do que ao sistema visual. Os dados obtidos neste trabalho também permitiram sugerir que o mecanismo de temporização interno aparentemente não é único, e apresenta alterações se funcionar em contexto auditivo ou visual.
