Resumo: BACKGROUND: Significant deficits in emotional recognition and social perception characterize patients with schizophrenia and have direct negative impact both in inter-personal relationships and in social functioning. Virtual reality, as a methodological resource, might have a high potential for assessment and training skills in people suffering from mental illness. OBJECTIVES: To present preliminary results of a facial emotional recognition assessment designed for patients with schizophrenia, using 3D avatars and virtual reality. METHODS: Presentation of 3D avatars which reproduce images developed with the FaceGen® software and integrated in a three-dimensional virtual environment. Each avatar was presented to a group of 12 patients with schizophrenia and a reference group of 12 subjects without psychiatric pathology. RESULTS: The results show that the facial emotions of happiness and anger are better recognized by both groups and that the major difficulties arise in fear and disgust recognition. Frontal alpha electroencephalography variations were found during the presentation of anger and disgust stimuli among patients with schizophrenia. DISCUSSION: The developed program evaluation module can be of surplus value both for patient and therapist, providing the task execution in a non anxiogenic environment, however similar to the actual experience.

A realidade virtual apresenta grandes potencialidades para a avaliação e o treino de competências em pessoas com doença mental. OBJETIVOS: Apresentar os resultados preliminares de um programa construído para avaliação do reconhecimento emocional de faces por pessoas com esquizofrenia, utilizando avatares 3D e realidade virtual. MÉTODOS: Apresentação de avatares 3D que reproduzem expressões emocionais, construídas por meio do FaceGen® e integradas num ambiente virtual tridimensional. Apresentou-se cada avatar a 12 doentes com esquizofrenia e a 12 pessoas sem patologia psiquiátrica, avaliando as respostas de reconhecimento e a atividade eletroencefalográfica frontal. RESULTADOS: Os resultados demonstraram que as expressões de alegria e raiva foram as mais bem reconhecidas pelos dois grupos, enquanto de medo e nojo foram as de maior dificuldade. Verificaram-se alterações na atividade alfa frontal para os estímulos raiva e nojo na amostra de doentes com esquizofrenia. CONCLUSÃO: Apesar de algumas expressões emocionais poderem ser melhoradas, o programa desenvolvido pode constituir uma mais-valia para o paciente e para o terapeuta, proporcionando a execução da tarefa em condições não ansiogênicas e aproximadas à experiência real.Repositório Científico do Instituto Politécnico do PortoSouto, TeresaBaptista, AlexandreTavares, DianaQueirós, CristinaMarques, António2019-10-04T14:42:33Z20132013-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10400.22/14678eng10.1590/S0101-60832013000400001info: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:RCAAP2023-12-13T01:49:37Zoai:recipp.ipp.pt:10400.22/14678Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T17:34:29.937338Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
