A mind in a disk: the attribution of mental states to technological systems

This paper reports a study about the role of different variables in the process of attributing mental states to technological systems, variables such as the number of figural elements displayed in the system and the personality traits of the subjects interacting with the systems. In an experiment, participants were interacting with a computer on whose screen several disks of various sizes and colours were blinking at different rates. Each time a disk reappeared on the screen its position was randomly varied. As in a videogame, participants had to click on the disks to increase their score. The results showed that, even in the case of such a simple system, subjects believed that the figural elements they were interacting with had some form of mental states, although their confidence in these beliefs varied in the different experimental conditions. The confidence level of the attributions, in fact, was not the same for all the different mental states considered, and it varied also both with the number of elements being displayed as well as with some personality traits of the subjects.
