spelling Perception of biological motion during locomotion in a virtual environmentScience & TechnologySocial SciencesPerception, vol. 36 (2007), supplementThe classical studies on the perception of biological motion (BM) use impoverished stimuli without translation for the identification of moving patterns. A previous psychophysical study demonstrated that a velocity match between translational point-light walker (PLW) was poorest and greatly biased by background contrast when compared with rigid translational motion. The current work combines two methodologies to develop the study of BM perception. A com- putational method considers the quality and quantity of information presented by BM stimuli. The impoverishment of PLW leads to a decrease of the body rigidity increasing the patterns complexity. The relative motion between opposing vectors in complex patterns may contribute to an impaired speed perception. We manipulated the structure of BM stimuli differentiating complexity levels through an optic flow analysis. Moreover, the visual analysis of human motion in a classical setup differs substantially from analysis under more realistic conditions. An action ^ perception paradigm in a virtual environment allows us to compare perceptive judgments raised by different stimuli representations during locomotion and to gather visually guided motor responses.Fundação para a Ciência e a Tecnologia (FCT)Pion Ltd.Universidade do MinhoMouta, SandraSantos, Jorge A.2007-08-292007-08-29T00:00:00Zconference objectinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://hdl.handle.net/1822/27220eng0301-0066http://www.perceptionweb.com/ecvp/ecvp07.pdfinfo: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:RCAAP2024-05-11T04:33:57Zoai:repositorium.sdum.uminho.pt:1822/27220Portal AgregadorONGhttps://www.rcaap.pt/oai/openairemluisa.alvim@gmail.comopendoar:71602024-05-11T04:33:57Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
