Early sensitivity to arguments: how preschoolers weight circular arguments

Area of Science:

• Cognitive Development
• Developmental Psychology
• Argumentation Studies

Background:

• Observational studies indicate children's argument evaluation skills emerge early.
• Previous experimental research on argument sensitivity has not included children under 5 years old.

Purpose of the Study:

• To investigate argument weighting abilities in preschoolers aged 3 to 5 years.
• To examine sensitivity to circularity, a common logical fallacy, in young children.

Main Methods:

• An experiment tested 3-, 4-, and 5-year-olds, plus adults, on argument evaluation.
• Participants chose between contradictory opinions supported by strong, circular, or unsupported arguments.

Main Results:

• All age groups preferred opinions with strong arguments over circular ones.
• 4- and 5-year-olds, unlike 3-year-olds and adults, favored circular arguments over unsupported ones.

Conclusions:

• Children aged 3 possess basic argument evaluation skills, processing content to discern non-circular from circular arguments.
• Older preschoolers (4-5 years) may employ a heuristic, using circular arguments as a cue for speaker dominance.
