Subclaims¶
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 i3 The TEEN group exhibited faster SSRT than the CHILD group on both tasks. → Sinopoli 2011
q3 i2 A reward by age group interaction showed the TEEN group inhibited a greater percentage of responses than the CHILD group in the NO and LOW conditions. → Sinopoli 2011 (2)
Evidence¶
Sinopoli 2011¶
Sinopoli, K.J., Schachar, R., & Dennis, M. (2011). Reward Improves Cancellation and Restraint Inhibition Across Childhood and Adolescence. Developmental Psychology, 47(5), 1479-89. https://doi.org/10.1037/a0024440
q3 · i3 · causal · r2
Repeated measures ANOVA comparing TEEN (13-17 years) and CHILD (7-12 years) groups on SSRT. The article reports faster SSRT for adolescents with partial η2=0.322, evident on both tasks.
"The TEEN group exhibited faster SSRT relative to the CHILD group (F(1, 39)=18.528, p<0.001, partial η2=0.322), and this effect was evident on both cancellation and restraint tasks (age group by task interaction, linear effect, F(1, 39)=5.715, p=0.022, partial η2=0.128)."
Sinopoli 2011 (2)¶
Sinopoli, K.J., Schachar, R., & Dennis, M. (2011). Reward Improves Cancellation and Restraint Inhibition Across Childhood and Adolescence. Developmental Psychology, 47(5), 1479-89. https://doi.org/10.1037/a0024440
q3 · i2 · causal · r1
Repeated measures ANOVA of percent inhibition by age group and reward condition. The article reports a reward by age group interaction with partial η2=0.086; adolescents out-inhibited children in NO and LOW conditions, with similar commission errors in HIGH.
"there was a significant reward by age group interaction (linear effect, F(2, 78)=3.683, p=0.030, partial η2=0.086) revealing that the TEEN group was able to inhibit a greater percentage of responses relative to the CHILD group in the NO and LOW conditions."
Discussion¶
Related Claims¶
- Task-demand clusters differ in useful age ranges, with perceptual inhibition developing earliest and motivational inhibition latest — related
- Interventions were effective across all child and adolescent age groups, with no particular age group in which interventions were most effective. — related
- Congruency effects on both numerical and non-numerical inhibition tasks occur in all three age groups, with an age-by-congruency interaction only on the numerical task — related
- Reward improves the speed of inhibitory control (SSRT) in both cancellation and restraint tasks in children and adolescents — related
- Reactive inhibition speed and accuracy improve with age between 8 and 11 years, while proactive response slowing does not increase with age — related
- SSRT was faster in the cancellation task than in the restraint task, supporting inhibition as a non-unitary construct — related
