Summary
Comparison directionality arises from how systematically information is structured. More systematic items are preferred as the base in comparisons, influencing inference and perceived informativity.
Area of Science:
- Cognitive Psychology
- Cognitive Science
- Linguistics
Background:
- Comparison asymmetries, where A is compared to B differently than B to A, are common.
- Existing theories often focus on feature differences or stimulus properties.
Purpose of the Study:
- To propose and test a novel account of comparison asymmetries based on structural alignment and mapping.
- To investigate the role of informativity and systematicity in driving comparison directionality.
Main Methods:
- Multiple experiments (1-6) were conducted using passages and comparing their systematicity.
- Structural alignability was manipulated and assessed.
- Inference projection and perceived informativity were measured in asymmetric comparisons.
Main Results:
- A preference was found for placing the more systematic item in the base position of a comparison.
- Structural alignability was crucial for these asymmetries.
- Systematicity, not feature set size, predicted asymmetries.
- Comparisons with the more systematic item as the base led to greater inference projection and higher perceived informativity.
Conclusions:
- Comparison asymmetries are driven by directional differences in informativity, predicted by the relative systematicity of items.
- This account explains asymmetries without relying on subjective similarity or stimulus bias.
- It offers a unified framework for understanding literal comparisons, analogies, and metaphors.
