Exemplar by feature applicability matrices and other Dutch normative data for semantic concepts.

Area of Science:

• Cognitive Psychology
• Linguistics
• Computational Linguistics

Background:

• Features are fundamental to understanding semantic concepts in language and cognition.
• Research in semantic concept representation relies heavily on identifying and utilizing these features.
• Existing datasets lack comprehensive feature information for diverse semantic categories.

Purpose of the Study:

• To delineate important features for natural language concepts.
• To investigate the use of these features in semantic concept representation.
• To provide a valuable dataset for future research in this area.

Main Methods:

• Conducted a feature generation task using exemplars and labels from 15 semantic categories.
• Assessed feature importance through generation frequency and relevance judgments.
• Created exemplar-by-feature applicability matrices for animals and artifacts.
• Collected various ratings (typicality, goodness, associative strength, etc.) for category exemplars.

Main Results:

• Identified and quantified the importance of features across 15 semantic categories.
• Generated extensive applicability matrices detailing feature relevance for specific items.
• Compiled a comprehensive dataset including multiple psycholinguistic variables for category exemplars.
• The data is made available through the Psychonomic Society's Archive of Norms, Stimuli, and Data.

Conclusions:

• The study provides a foundational dataset for feature-based semantic concept representation.
• The generated data facilitates further investigation into the structure of semantic memory.
• Availability of these norms supports cross-linguistic and cross-cultural research on concepts.
