An investigation of the effect of logical structures on Chinese preschool children's counterfactual reasoning development.

ABSTRACT

Counterfactual reasoning helps people to learn from the past to prepare for the future. In contrast to English with counterfactual markers that directly signal counterfactual reasoning, Mandarin Chinese indicates counterfactual reasoning by counterfactuality enhancers, which enhance rather than directly signal entry into the counterfactual realm. There are more counterfactuality enhancers in subtractive than additive counterfactual premises. Hence, Chinese-speaking children might more readily interpret subtractive than additive counterfactual premises, leading to better performance on subtractive than additive counterfactual reasoning tasks. This difference between logical structures might be larger in Chinese than English, as English has counterfactual markers, which enable direct inference of counterfactuality regardless of logical structures. Consistent with these propositions, in two experiments, the present study found that Chinese preschool children's accuracy was significantly higher for subtractive than additive counterfactual reasoning. Also, the difference between logical structures was much larger compared to a previous study in UK children using a similar counterfactual reasoning task. Hence, the use of counterfactuality enhancers in Chinese might shape a developmental difference between subtractive and additive counterfactual reasoning. Parents and teachers may attend to this developmental pattern when scaffolding children's counterfactual reasoning growth.
