Logic

Background:

Understanding conditional reasoning is crucial for cognitive development.
Previous research indicates age-related differences in logical reasoning abilities.

Purpose of the Study:

To investigate how age impacts the ability to reason with conditional (if-then) premises.
To explore the influence of factual accuracy and context on conditional reasoning.

Main Methods:

Two studies examined conditional reasoning in children and adolescents aged 5-18 years.
Participants reasoned with factually accurate, inaccurate, or fantasy-based conditional premises.

Main Results:

Younger children (10-13 years) struggled with accepting contrary-to-fact premises.

Related Experiment Videos

Older adolescents (15-18 years) accepted premises but found reasoning more challenging.

A fantasy context aided younger children in accepting false premises.

Conclusions:

Acceptance of contrary-to-fact premises develops with age.
Cognitive processes, potentially representational, influence logical reasoning with conditional statements.
