Resumo: Little is known about the perception of another vehicle during self-motion. This situation occurs, for instance, when a car’s driver approaches an intersection with ongoing traffic. By graphic visual simulations, we showed that the perception of the other car’s trajectory relies both on global visual information, such as the optical flow field, and on local visual information, such as the optical motion of the moving object and the relative optical motion between the moving object and fixed elements in the environment. We also showed that environmental factors (presence of a road sign, level of realism of visual scenes), driving experience (novice versus experienced drivers) and perceptual style (field dependence versus field independence) contributed to perceptual judgments.

Por exemplo, esta situação ocorre quando num cruzamento o condutor se confronta com outros veiculos em aproximação. Através de simulações grificas mostramos que a percepção da trajectória de outro veiculo depende quer da informação visual global, tal como a do campo de fluxo óptico, quer da informação visual local, tal como a do movimento óptico do outro veiculo e a do movimento optico relativo entre este e objectos fixos no ambiente. Mostramos também que os factores ambientais (presenqa de um sinal de trânsito, nivel de realismo das sequencias visuais), a experiencia de condução (condutores iniciados versus condutores experientes) e o estilo perceptivo (dependencia versus independhcia de campo) contribuem para as avaliações perceptivas.Instituto Superior de Psicologia AplicadaRepositório do ISPABerthelon, CatherineMestre, Daniel2014-10-17T19:21:58Z1995-01-01T00:00:00Z1995-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10400.12/3126engAnálise Psicológica, 13, 291-2940870-8231info:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2022-09-05T16:38:59Zoai:repositorio.ispa.pt:10400.12/3126Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T15:21:02.669846Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
