This study explored the effect of integrated-focus (focusing on a depiction of overall gains/losses) versus trial-focus (focusing on gains/losses at each trial) on choice in a preschool variant of the Iowa Gambling task. Participants included 65 preschoolers (M = 47.82, SD = 7.29). Children completed two versions of the Preschool Gambling task, three cool executive function tasks, a moral reasoning task, and an affective perspective taking task. The results indicated that while the integrated-focus condition led to improvement in the awareness of the game, the condition effect was moderated by age for decision-making choice; older preschoolers showed improvement in decision-making in the integrated focus condition, while younger preschoolers showed no condition effect. Further analysis indicated that differences in the increase of advantageous choice across blocks and the condition effect were partly explained by these differences in awareness. Furthermore, a component of cool executive function (shifting) was associated with the latter phase of decision-making. The findings additionally indicated an association of advantageous decision-making with moral/emotional measures, suggesting that the PGT may be a potentially useful clinical tool for early assessment. Finally, the findings of the current study have implications for how hot and cool executive function abilities may work together to enable adaptive decisions.
