             The idea of robot rulers,friends and lovers has been a topic of science fiction novels for years.

             But according to one mathematical model of how our brains create consciousness,emotional machines will never exist.

             This is because computers cant handle any process that completely integrates infor? mation,so they cannot be conscious or feel,one expert says.

             A mathematical model for consciousness,developed by Giulio Tononi at the University of Wisconsin-Madison,says that the ability to integrate information is a key feature of con?sciousness.

             He believes that integrated information cant be broken down into smaller pieces in conscious minds,because the brain contextualizes (将…融入背景) information.

             For example,when we see a red circle our brains don't see the shape as a colouiiess circle plus a shapeless coloured area,New Scientist reported. Instead we see it as a whole — a red circle; we understand the “wider picture”.

             It's easy enough for machines to edit a collection of individual images (图像) ,but memories are made up of a bank of intertwined(相互交织的) images and experiences and cannot be changed in the same way.

             Researchers have used mathematics to show that computers cannot handle the complex processes needed to fit pieces of information together perfectly.

             Therefore,if consciousness is based on the integration of lots of pieces of information,computers cant be conscious and cant experience emotions like humans.

             Professor Phil Maguire of the National University of Ireland in Maynooth says that consciousness cannot be created in a physical machine in limited time using limited memory.

            “It doesn’t necessarily mean that there is some magic going on in the brain that involves some forces that cant be explained physically. It is just so complex that it's beyond our abilities to change it,” he said.

             His research may mean that lonely humans will not find love with a robot; they are unlikely to be made their slaves either.
