TOK notes 2-13-02 Wednesday We talked about perception and the movie 'At First Sight' The other questions we explored: If humans are only sensitive to a certain range of stimuli, what consequences and limitations are there? How does technology extend and modify our capabilities? We talked about how it's possible that we are not perceiving certain things because we do not have the tools to do so. If this is the case, how could we ever be sure that we had an accurate picture of how things really are. We also talked about how human perception can be deceived. Our eyes work in such a way that they interpret the image they see in the most probable way. That is why optical illusions work on us. Other questions asked: Do you ever have dreams that feel real? Can you always tell the difference between a dream and reality? How do you do it?
