Figure 3 and the accompanying text report that as discrimination difficulty increased, both accuracy and the proportion of high bets decreased across conditions, with main effects of difficulty on accuracy (F(2, 42) = 274.51, p < .001) and on risk (F(2, 42) = 30.30, p < .001).

"Accuracy and the proportion of high bets decreased with increasing difficulty for both conditions (main effect of difficulty across conditions: accuracy, F(2, 42) = 274.51, p < .001;risk, F(2, 42) = 30.30, p < .001)."

• Children aged 5 to 8 show metacognitive sensitivity in a nonverbal wagering task, betting more on correct than incorrect discriminations — related
• With increasing n-back task difficulty, reaction times increase and accuracy decreases — a broader claim this one bears on
• Working memory load degrades discrimination accuracy and slows responses in youth — related
• Item discriminating value as coefficient of variation decreases monotonically as number of correct answers increases, giving a negative difficulty–discrimination relationship — related
• Metacognitive sensitivity increases with age between 5 and 8 years, similarly across number and emotion domains — related
