“…For example, when children are asked to choose between a small immediate reward and a larger delayed reward, 3-year-olds typically choose the small reward that they can immediately receive, whereas 4year-olds typically choose the larger reward that they will receive after a delay, across children from Canada (e.g., Hongwanishkul et al, 2005;Lemmon & Moore, 2007;Prencipe & Zelazo, 2005;Thompson et al, 1997), Britain (Ding et al, 2021), and mainland China (Ding et al, 2021;Qu et al, 2012). Despite the cross-cultural differences in DoG, Chinese children and Western children showed similar developmental trajectories with age (Ding et al, 2021;Qu et al, 2012). Zhao et al (2021) found that the age-related development of selfcontrol (indicated by a composite score of inhibitory control and the "delay" self-control) did not differ across selective samples of children from the U.S., China, Singapore, and Peru.…”
