Direct linkSabbagh, Mark A.; Bowman, Lindsay C.; Evraire, Lyndsay E.; Ito, Jennie M. B. – Child Development, 2009
Baseline electroencephalogram (EEG) data were collected from twenty-nine 4-year-old children who also completed batteries of representational theory-of-mind (RTM) tasks and executive functioning (EF) tasks. Neural sources of children's EEG alpha (6-9 Hz) were estimated and analyzed to determine whether individual differences in regional EEG alpha…

Liu, David; Sabbagh, Mark A.; Gehring, William J.; Wellman, Henry M. – Child Development, 2009
Young children show significant changes in their mental-state understanding as marked by their performance on false-belief tasks. This study provides evidence for activity in the prefrontal cortex associated with the development of this ability. Event-related brain potentials (ERPs) were recorded as adults (N = 24) and 4-, 5-, and 6-year-old…

Lackner, Christine L.; Bowman, Lindsay C.; Sabbagh, Mark A. – Neuropsychologia, 2010
Representational theory of mind (RTM) development follows a universal developmental timetable whereby major advances in reasoning about mental representations occur between the ages of 3 and 5 years old. This progression appears to be only absent in the case of specific neurodevelopmental impairments, such as autism. Taken together, this suggests…

Liu, David; Wellman, Henry M.; Tardif, Twila; Sabbagh, Mark A. – Developmental Psychology, 2008
Theory of mind is claimed to develop universally among humans across cultures with vastly different folk psychologies. However, in the attempt to test and confirm a claim of universality, individual studies have been limited by small sample sizes, sample specificities, and an overwhelming focus on Anglo-European children. The current meta-analysis…

Sabbagh, Mark A.; Seamans, Elizabeth L. – Developmental Science, 2008
We examined whether individual differences in children's performance on a scaled battery of theory-of-mind tasks was predicted by parents' performance on an adult theory-of-mind task. Forty-six 3-year-old children and their parents participated in this study when children were aged 2;11 to 4;0. Thirty dyads returned 6 months later for a second…

Sabbagh, Mark A.; Moses, Louis J.; Shiverick, Sean – Child Development, 2006
Two studies were conducted to investigate the specificity of the relationship between preschoolers' emerging executive functioning skills and false belief understanding. Study 1 (N=44) showed that 3- to 5-year-olds' performance on an executive functioning task that required selective suppression of actions predicted performance on false belief…
