Learning outcomes This course aims to acquire knowledge in the field of visual perception and the contact with psychophysical techniques applied to vision.

At the end of the course the student should be able to:
- Identify problems related to color discrimination;
- Understand, at the current state-of-the-art, the mechanisms of color perception, space perception, motion perception and depth perception;
- Know the psychophysical techniques suited to studying the mechanisms of perception mentioned above;
- Explain the origin of optical and visual illusions.
Syllabus 1. Perception of light.
2. Color Vision.
3. Anomalies of Color Vision.
4. Space perception.
5. Temporal aspects of vision.
6. Motion perception.
7. Depth perception.
8. Vision and perception illusions.

Planned learning activities and teaching methods The course is organized into TP lectures and laboratory classes. The TP classes include the presentation of theoretical material followed by working examples of the effects described. The practical classes include psychophysical experiments based on the presentatios of physical stimuli to real observers and interpretation of their perceptions, based on psychophysical principles. Colored stimuli, with different sizes, shapes, temporal frequency presentation, moving or stationary, with or without depth are used.
Metodologias de Ensino e Critérios de Avaliação A classificação de ensino-aprendizagem (CEA) é obtida atraves da expressão: CEA = 1/2T + 1/2P, onde T é a classificação do teste teórico (frequência) e P é a classificação de laboratório. O aluno obterá aprovação por frequência e será dispensado de exame se T >= 9,5 valores e P >= 9,5 valores. A classificação final por exame (CF) é obtida atraves da expressão: CF = 1/2E + 1/2P, onde E é o teste de exame. O aluno obterá aprovação por exame se E >= 9,5 valores. Para obtenção de frequência, cada estudante deverá: - frequentar assiduamente as aulas práticas da disciplina (sendo-lhe permitida apenas uma falta não justificada), obtendo a classificação P, através da apresentação obrigatória de um relatório escrito por cada trabalho realizado; - entregar os relatórios nos prazos indicados; - obter P >= 9,5 valores; - ter um número mínimo de presenças em aulas teorico-práticas igual a metade das aulas leccionadas; - obter classificação superior a 6,0 valores na CEA.
Language Portuguese. Tutorial support is available in English.
