Inconsistency with prior knowledge triggers children's causal explanatory reasoning.

Area of Science:

• Cognitive Science
• Developmental Psychology
• Child Psychology

Background:

• Children's causal explanatory reasoning is crucial for learning.
• Explanations may be triggered by consistent or inconsistent events.

Purpose of the Study:

• To investigate what kind of events trigger causal explanatory reasoning in young children.
• To determine if explanations serve a confirmatory or discovery function.

Main Methods:

• Two studies were conducted with preschool children (N=80).
• Children were presented with events consistent and inconsistent with their prior knowledge.
• Children were asked to explain the outcomes.

Main Results:

• Inconsistent outcomes were a powerful trigger for children's explanations.
• Explanations for inconsistent events focused on internal causal properties, overriding appearances.
• Children's explanations for inconsistent events were more frequent.

Conclusions:

• Inconsistent events strongly motivate children to construct explanations.
• Children's explanations primarily function in the service of discovery.
• This suggests a discovery-driven model of children's causal reasoning.
