Evidence obtained with new experimental paradigms has renewed the debate on the development of theory of mind in general and false belief ascription in particular. Namely, several studies contend to prove that infants already have the capacity to attribute false beliefs. The aim of the current meta-analysis is to review and summarize the empirical evidence about spontaneous-response false belief tasks in infants younger than 2 years old. Fifty-six false belief conditions using the violation-of-expectation, the anticipatory looking and interactive paradigms were included in this meta-analysis, including 1469 infants. The role of several moderators was examined, following Wellman et al.ös meta-analysis (2001). Results show that correct performance on spontaneous-response false belief tasks was about 1.76 times more likely than incorrect performance (β = 0.57, 95% CI 0.33; 0.80, p
