Transfer of conditional reasoning: effects of explanations and initial problem types

Area of Science:

• Cognitive Psychology
• Human Reasoning

Background:

• Wason's selection task is a classic test of deductive reasoning.
• The 'thematic effect' shows people perform better on concrete, thematic problems than abstract ones.

Purpose of the Study:

• To investigate how explanations and problem characteristics influence reasoning transfer.
• To examine the role of problem similarity and explanation type on transfer.

Main Methods:

• Three experiments were conducted using Wason's selection task.
• Varied factors included problem type (abstract vs. thematic), explanations, verbalization, and problem similarity.

Main Results:

• Explanations facilitated reasoning transfer, especially from abstract to abstract problems.
• Transfer was greater from abstract problems than thematic ones, and particularly to similar problem types.
• Verbalization did not enhance transfer; problem similarity had no effect on thematic problems.

Conclusions:

• Reasoning transfer is influenced by explanation and problem type, with abstract problems showing greater transfer potential.
• Findings support the pragmatic reasoning schema hypothesis, suggesting abstract rules are more transferable.
• Understanding these factors can inform cognitive training and educational strategies.
