Subclaims¶

q3 i3 Latency of inhibitory control was faster when a response needed to be cancelled than when it needed to be restrained before initiation. → Sinopoli 2011

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 · r1

Repeated measures ANOVA comparing SSRT across the cancellation and restraint versions of the SST. The article reports a large task effect with partial η2=0.871, which the authors say supports the idea that IC is not a unitary construct.

"SSRT was faster in the cancellation task relative to the restraint task (linear effect, F(1, 39)=263.686, p<0.001, partial η2=0.871)."

• Reward improves the speed of inhibitory control (SSRT) in both cancellation and restraint tasks in children and adolescents — related
• Reward does not alter the speed or variability of response execution in either stop signal task — related
• Reactive inhibition speed and accuracy improve with age between 8 and 11 years, while proactive response slowing does not increase with age — related
