In chapter 4, Sensation &perception, there were a lot of different concepts about how our senses and brain are related and how they processed. Among them, 'the visual system (visual perception) of our body' is the most interesting part for me which arouse my attention. Our eyes seem to function a lot as we live, and they really do. However, it is really easy to deceive our eyes more than we thought. For the basic example, we do not distinct colors easily when we suddenly see the bright lights after get out in the dark. It's because of rods and cones of our eyes which allow us to distinguish low levels of lights and also the colors. Other than this example, there are numerous ways to deceive our eyes only using by editing lines or visual effects. In addition, our eyes do not recognize not only the visual pictures on the plane paper, but also the motions in three-dimensional in our lives. In discussion class, we concluded that the most optical illusions are the result of influence of background patterns on the overall design, adjustment of our perception at the boundaries of areas, our inability to interpret the spatial structure of an object from the context, and so on. Through these concepts, I recognized that there might be a lot of things that I do not see exactly what's there in the world. Everyone might think that they see the things right, but they actually don't, which is the funniest part of this section. And lastly, the picture at the top is one example about deceive visual perception that I took in trick art museum, and rest of the examples at the bottom is other examples from other websites.
