Manipulating objects and telling words: a study on concrete and abstract words acquisition

Area of Science:

• Cognitive Psychology
• Linguistics
• Neuroscience

Background:

• The Words as Tools (WAT) proposal suggests concrete and abstract words differ due to their acquisition modalities.
• Concrete words are often acquired through direct interaction with objects, while abstract words are learned through observation or linguistic description.

Purpose of the Study:

• To investigate if different acquisition methods create differences between concrete and abstract words, as predicted by the WAT proposal.
• To examine how manipulating objects versus observing them affects category formation and word association.

Main Methods:

• Four experiments involved participants acquiring novel concepts through object manipulation or observation.
• Tasks included category judgments, label association, feature production, and a color verification task using manual or verbal responses.

Main Results:

• Forming abstract categories was consistently harder than concrete ones.
• Abstract words elicited more verbal information, while concrete words evoked more perceptual properties.
• Verbal responses (microphone) showed an advantage for abstract words, particularly when explanations were provided.

Conclusions:

• The findings support the Words as Tools (WAT) proposal, linking acquisition modality to word type differences.
• Concrete words are associated with manual/perceptual information, and abstract words with verbal information.
• These results have implications for theories and computational models of language grounding.
