Perception interests me so much. That's because we see what we are conditioned to see by our experiences up to this point, and by our mindset. What picture do you see here, the old woman or the young woman? Keep looking at it to see another perception, and later below, do you see the vase or the faces? It depends on your perception.
By mindset I mean that whatever thoughts occupy your mind regularly will influence how you feel, and your feelings will dictate your behaviour. So for example, if you are negative most of the time, you will be pre-disposed to a negative mindset, and will tend to see the world as hostile, and the people in it as potentially dangerous. Fear drives you, and your ears will ***** up if there is bad news, forbodings and warnings. If on the other hand you have trained yourself to be positive and attract positive things into your life, you will not be attuned to hear the negatives, but will instead ***** up your ears if there's a chance of fun to be had, or a boost in the economy, or a good film (instead of a weepy one), and will choose positive friends who will reinforce the ideas you have about the world being a relatively good, safe and enjoyable place.
An experiment that I found interesting was done by the police, who wanted to look at why witnesses who came forward saying they had witnessed a crime, did not seem to see the same things, and their statements were often at odds with each other. People were invited to watch a police video of a violent crime and the participants (audience) had to write down their impressions immediately after the video ended. What was discovered was that people did not see what others saw, they had an individual view of the world according to their perception rather than reality, and what their pre-disposing mindset was. So the audience member who was fanatical about owning the latest cool trainers noticed the criminals' trainers, and was able to say that one of them was quite unusual. The art student noticed exactly what all the people were wearing, and even identified an unusual fabric or two which could be helpful in tracking the men. There was a nurse, and she was interested in the injuries, noting the time they occurred, and how long the victims had been bleeding for and knocked out, as she knew these factors were time critical. Another audience member was mad on cars, and his mindset made him notice them above all else; he reeedl off the makes and models, as well as engine size, unusual wheel trims, colour, and number plates. An older lady noticed a gripper (handicapped aid) in the house because her relative also had one. Other audience members noticed the hair, and details such as moustache, and food left on the table. It was so interesting, because no two people said exactly the same thing. Fascinated me!
