q3 i3 Across both stop signal tasks, latency to inhibit a response was faster under low- and high-reward conditions than under the neutral condition. → Sinopoli 2011

Repeated measures ANOVA on 43 typically developing participants aged 7-17 performing cancellation and restraint SST versions under NO, LOW, and HIGH reward conditions. The article reports a "significant main effect of reward on SSRT" with partial η2=0.211, with faster inhibition latency in reward conditions.

"A repeated measures ANOVA revealed a significant main effect of reward on SSRT (linear effect, F(2, 78)=10.401, p<0.001, partial η2=0.211; see Table 2). In both tasks, the latency to inhibit a response was faster in the reward conditions (LOW, HIGH) relative to the neutral (NO) condition."

Discussion¶

Related Claims¶

• Adolescents showed faster, more accurate, and less variable performance than children, with reward effects on inhibition accuracy differing by age — related
• SSRT was faster in the cancellation task than in the restraint task, supporting inhibition as a non-unitary construct — related
• Reward does not alter the speed or variability of response execution in either stop signal task — related
