After reading about John’s visual agnosia, it seems to me like he was taking a small piece of a big world and trying to interpret it in his own way and in my opinion, everyone does this. No one can know everything and so they take the experiences they have had and the lessons they have learnt and interpret it in their own way so in this sense, they live in their own world because their interpretation consists of a different foundation. We only ever see what we want to and not the whole picture. This is clearly shown when we saw the visual illusions today in the presentation. John could see and hear and function normally in terms of his sense but he couldn’t recognize objects or faces so he couldn’t interpret the object and fit it into everyday life.
For example, in an article I read, Daniel Simons and Daniel Levin did an experiment where they asked a person to walk up to a bystander and ask for directions and two other guys of completely different build, looks and skin colour walk in between them with a door and switch one person with the original confederate. It showed that more than 50% of the time the bystander doesn’t even realize that the person has changed and this shows that we only see what we want to see and not what it actually is. This relates to what we discussed in class because it shows how we live in our own versions of the world made up of things that we want to be there and maybe it’s completely different from other people’s or quite similar.
On a separate topic about sense perception but not really relate. I wonder if intuition is considered as a sense. Some people believe that intuition is the ‘sixth’ sense and I wonder if people don’t have this intuition if they would be similar to John’s case because they wouldn’t be able to integrate what their sense show into the real world.
