Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i2 The Task Type × Group interaction was significant, such that foster-care control children were impaired only on the post-switch card sort, not the pre-switch sort. → Lewis-Morrarty 2012
Evidence¶
Lewis-Morrarty 2012¶
Lewis-Morrarty, E., Dozier, M., Bernard, K., Terracciano, S., & Moore, S. (2012). Cognitive Flexibility and Theory of Mind Outcomes Among Foster Children: Preschool Follow-up Results of a Randomized Clinical Trial. Journal of Adolescent Health. https://doi.org/10.1016/j.jadohealth.2012.05.005
q3 · i2 · causal · r2
A 2 × 3 repeated measures ANCOVA (Task Type × Group, controlling for receptive language) revealed a significant Task Type × Group interaction (F(2, 59) = 3.63, p = .03), indicating the foster-care control deficit was specific to the set-shifting (post-switch) condition. The interaction accounted for approximately 11 percent of within-subjects variability (η2 = .11).
"A significant interaction between Task Type and Group was also found, F(2, 59) = 3.63, p = .03, such that FCC children attained significantly lower scores on the post-switch card sort, relative to the ABC group and to NFC children, but not on the pre-switch card sort, p > .05."
Discussion¶
Learner Variables¶
- Executive Function — outcome: instruction changes it
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 the ABC intervention showed stronger theory of mind at preschool age than foster children who received a control intervention — related
- Foster children who received the control intervention scored significantly lower on the post-switch task than never-fostered comparison children — possibly the same claim (merge candidate)
- Children typically perseverate on the Dimensional Change Card Sort at age 3 but can switch sorting rules from age 4 — a broader claim this one bears on
- Group differences in receptive language did not hold when controlling for SES, and receptive language was the covariate retained in the main analyses — related
- Children's cognitive flexibility improved on average from preschool to first grade — related
- Metacognitive reflection training improves young children's DCCS performance, with behavioral and neural changes — related
