Subclaims¶

q4 i? Exploratory moderation found no evidence that reward type moderates the reward effect on IC across monetary (k = 62), points (k = 13), and other (k = 3) reward categories. → Burton 2021

q4 · i? · quant-synthesis · r3

Exploratory moderator analysis on reward type. All three reward categories showed significant positive effects; the article reports "no evidence of moderation, χ2(2) = 2.863, p = .239".

"There were k = 62 effects using monetary reward (SMD = 0.392, 95% CI = [0.266, 0.518], Z = 6.093, p < .001, I2 = 94.68%), k = 13 effects using hypothetical "points" (SMD = 0.586, 95% CI = [0.220, 0.952], Z = 3.138, p = .002, I2 = 93.02%)"
