Recursive belief manipulation and second-order false-beliefs

The literature on first-order false-belief is extensive, but less is known about the second-order case. The attainment of secondorder false-belief mastery seems to mark a cognitively significant stage, but what is its status? Is it an example of complexity only development, or does it indicate that a more fundamental conceptual change has taken place? In this paper we extend Braüner’s hybrid-logical analysis of first-order falsebelief tasks (Braüner, 2014, 2015) to the second-order case, and argue that our analysis supports a version of the conceptual change position.
