Subclaims¶

q4 i? Exploratory moderation found no evidence that age moderates the reward effect on IC: child samples (k = 28, SMD = 0.515) and adult samples (k = 50, SMD = 0.396) did not differ significantly. → Burton 2021

q4 · i? · quant-synthesis · r3

Exploratory moderator analysis comparing child (younger than 18) versus adult samples. Both subgroups showed significant positive reward effects, but the test found "no evidence of moderation, χ2(1) = 0.877, p = .349".

"There were k = 28 effects from child samples (SMD = 0.515, 95% CI = [0.315, 0.714], Z = 5.053, p < .001, I2 = 92.18%) and k = 50 adult samples (SMD = 0.396, 95% CI = [0.247, 0.544], Z = 5.217, p < .001, I2 = 95.22%). There was no evidence of moderation, χ2(1) = 0.877, p = .349."

Discussion¶

Related Claims¶

• The effect of reward on inhibitory control is not moderated by reward type (monetary vs points vs other)
• A meta-analysis found no evidence that clinical status, including ADHD and substance use disorder samples, moderates the effect of reward on inhibitory control
• The reward effect on inhibitory control is significant across all six IC task types, but task type significantly moderates the effect, with the largest effect in Stroop tasks
• The prospect of reward for successful inhibition significantly improves inhibitory control (SMD = 0.429) compared with no-reward conditions — related
