A central tenet of constructivist models of conceptual development is that children's initial conceptual level constrains how they make sense of new evidence and thus whether exposure to evidence will prompt conceptual change. Yet little experimental evidence directly examines this claim for the case of sustained, fundamental conceptual…

In two experimental and exploratory studies, we wanted to test the differentiated effects on preschoolers with externalizing behavior (EB) of two short-term social information processing (SIP) and Theory of Mind (ToM) training sessions, in comparison with typically developing (TD) preschoolers or with preschoolers with EB whom didn't receive…

In a training study, the authors addressed whether or not preschoolers' difficulty with false belief is due to a domain-specific problem with mental states. Following Slaughter's (1998) design, 57 children who failed a false-belief (FB) pretest received two sessions of training on either an FB, false sign (FS), or control task. All children were…

In an experimental design, we examined the effects of middle-term training in social information processing (SIP) and in Theory of Mind (ToM) on preschoolers' social cognition and social adjustment. 48 preschoolers took part in a pre-test and post-test session involving cognitive, socio-cognitive and social adjustment (direct and indirect)…

The present study investigated how Chinese children develop theory of mind (ToM) in a language environment with limited mental state talk that is rich in behavior discourse. In Study 1, 60 mothers shared a wordless storybook with their 3-4-year-olds. The children completed two false-belief tasks and the Peabody Picture Vocabulary Test-Revised at…

Using an experimental approach, our study examined the differentiated effects on pre-schoolers' social cognition of two short-term social information processing (SIP) and Theory of Mind (ToM) training sessions dealing with emotions and beliefs. The links between ToM, SIP, and social adjustment or externalizing behavior were examined. 47…

In this study the authors investigated whether training preschool children in the use of mental state lexicon plays a significant role in bringing about advanced conceptual understanding of mental terms and improved performance on theory-of-mind tasks. A total of 70 participants belonging to two age groups (3 and 4 years old) were randomly…
