Global development, diffusion and implementation of the human-centredness paradigm can be performed at best when supported by a study of our mental activity. By analysing our mental operations, we can understand how human needs, interests, values and creativity take form, what each consists of, how it is possible to expand, modify and generate them. The proposed model of mental activity is based on attentional movement. The new opportunities, both ethical and social, offered by such a study are presented.
