Subclaims¶

q3 i3 In the randomized trial follow-up, foster children who received ABC scored significantly higher on the penny-hiding theory of mind task than foster children who received the control intervention (d = 1.08). → Lewis-Morrarty 2012 q3 i? Foster children who received ABC did not differ significantly in theory of mind from never-fostered comparison children. → Lewis-Morrarty 2012 (2)

Evidence¶

Lewis-Morrarty 2012¶

q3 · i3 · causal · r2

A univariate ANCOVA controlling for receptive language compared theory of mind (penny-hiding game) performance across the three groups at ages 4–6. The ABC group "scored higher than children in the FCC group" with a large effect size (d = 1.08); the overall Group main effect was significant (F(2, 59) = 4.59, p = .01).

"Contrasts using a Bonferroni-adjusted critical value showed that children in the ABC group (M = 8.76, SD = 0.44) scored higher than children in the FCC group (M = 6.80, SD = 2.51) on the theory of mind task (Mcontrast = 1.96, p = .01, CI 95: 0.49, 3.44), and the effect size for this contrast was large (d = 1.08)."

q3 · i? · causal · r2

Follow-up contrasts showed ABC foster children's theory of mind scores did not differ significantly from never-fostered comparison children (p = .90), while the foster-care control group scored marginally lower than comparison children (p = .05).

"Relative to NFC children (M = 8.17, SD = 1.71), children in the ABC group did not differ significantly in their theory of mind scores (Mcontrast = 0.60, p = .90, CI 95: −0.81, 2.01), but children in the FCC group scored marginally lower than children in the NFC group (Mcontrast = −1.37, p = .05, CI 95: −0.02, −2.72)."

Related Claims¶

• Foster children who received the ABC intervention in infancy showed stronger cognitive flexibility at preschool age than foster children who received a control intervention — related
• Foster children who received a control intervention showed a specific post-switch (set-shifting) deficit on the card-sort task, with no group difference on the pre-switch trials — related
• Foster children who received the control intervention scored significantly lower on the post-switch task than never-fostered comparison children — related
• Group differences in receptive language did not hold when controlling for SES, and receptive language was the covariate retained in the main analyses — related
• Prenatal risk indices were not significantly associated with cognitive flexibility or theory of mind outcomes in this sample — related
