How do you think we see? Do you think that the constructivist and ecological approaches fully describe all the aspects of the human perceptual system? Think about the following issues:

Can you think of any visual effect, which is not adequately described by the two theories we have looked at? What are the biggest strengths and weaknesses of each theory? Do you think that the theories are mutually exclusive, or can you use on theory in some instances and the other theory at other times? What do you think about affordances – it is really an ecological phenomenon, or is there some constructivism at play? What do you think of the constructivist's assertion that babies see in a completely different way to adults?
