Integrated versus trial specific focus improves decision-making in older preschoolers.

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.

Heterogeneity of decision-making strategies for preschoolers on a variant of the IGT.

Adaptive decision-making strategies are critical for dealing with the complexity of the social world. The present study investigated the use of decision-making strategies in preschoolers and their association to prosocial behavior and peer problems. Eighty-six preschoolers aged 3- and 4-years completed the preschool decision-making task (PGT), a child variant of the Iowa Gambling task . Win-stay/lose-shift responses along with exploration (consecutive choices from the advantageous deck) and exploitation (shifting between options) were examined. Preschoolers showed a range of strategies, with 4-year-olds adapting their approach as the game progressed and making better use of feedback in comparison to 3-year-olds. Children who differed in terms of choices from the advantageous deck were distinguished by different combinations of exploration and exploitation. Furthermore, unique combinations of decision-making strategies also distinguished children who were rated as high versus low in prosocial behavior as well as children rated as having a high versus low level of peer problems. The findings suggest that consideration of strategies used in decision-making tasks could provide useful insight in a clinical setting, particularly for populations with social difficulties.
