[eng] Theory of mind, the ability to attribute mental states to others to predict or explain their
behaviour, fully develops by the age of four when children consistently pass explicit
false-belief tasks (Wellman et al., 2001). However, several implicit measures of falsebelief
understanding, like looking behaviour and interactiva responses, indicate that
infants show an early competence to attribute false beliefs (Baillargeon et al., 2010;
Buttelmann et al., 2014; Senju et al., 2011).
