What is mentalization? When we mentalize we are engaged in a form of (mostly preconscious) imaginative mental activity that enables us to perceive and interpret human behavior in terms of intentional mental states (e.g., needs, desires, feelings, beliefs, goals, purposes, and reasons) (Allen, Fonagy, & Bateman, 2008). Mentalizing must be imaginative because we have to imagine what other people might be thinking or feeling. We can never know for sure what is in someone else’s mind (Fonagy, Steele, Steele, & Target, 1997). Moreover, perhaps counterintuitively, we suggest that a similar kind of imaginative leap is required to understand our own mental experience, particularly in relation to emotionally charged issues. We shall see that the ability to mentalize is vital for self-organization and affect regulation. The ability to infer and represent other people’s mental states may be uniquely human. It seems to have evolved to enable humans to predict and interpret others’ actions quickly and efficiently in a large variety of competitive and cooperative situations. However, the extent to which each of us is able to master this vital capacity is crucially influenced by our early experiences as well as our genetic inheritance.
