The Formal Structure of Kind Representations

Area of Science:

• Cognitive Science
• Psychology
• Linguistics

Background:

• Generic language relies on kind representations (e.g., dog, planet).
• Individuals possess generic-supporting and accidental properties.
• Some generic-supporting properties have a principled connection to the kind (e.g., a watch's ability to tell time).

Purpose of the Study:

• To investigate if principled connections form the formal structure of kind representations.
• To test if principled connections influence the structuring of newly learned kind representations.

Main Methods:

• Experiment 1: Participants learned a novel kind ('blick') with a property introduced via linguistic frames indicating principled connection versus generic support.
• Experiment 2: Assessed if introduced properties were generic licensing, regardless of the frame.

Main Results:

• Introducing a property with a principled connection frame led participants to infer consequences of principled connections without direct evidence.
• Frames lacking principled connection evidence did not yield the same inferences.
• All properties were found to be generic licensing, irrespective of the introduction frame.

Conclusions:

• The distinction between principled and merely generic-supporting properties is part of the formal structure of kind representations.
• This distinction actively structures novel kind representations, influencing conceptual inference and understanding.
