The Development of Abstract Word Meanings

Area of Science:

• Developmental Psychology
• Cognitive Science
• Linguistics

Background:

• Early word acquisition in children is strongly linked to sensorimotor experiences, leading to concrete meanings.
• The acquisition process for abstract word meanings, learned later, is less understood.
• Existing research suggests a connection between word concreteness and the age at which words are acquired.

Purpose of the Study:

• To investigate the relationship between word meaning concreteness and age of acquisition.
• To explore how different types of experiences contribute to learning concrete versus abstract word meanings.

Main Methods:

• Collected meaning-specific concreteness ratings for a range of words.
• Analyzed age-of-acquisition data from large-scale vocabulary tests spanning children to college students.
• Examined correlations between concreteness ratings and age-of-acquisition data.

Main Results:

• Words with more concrete meanings were acquired earlier in development.
• Words with more abstract meanings were acquired later, especially those typically considered concrete.
• A significant correlation was found between meaning concreteness and age of acquisition.

Conclusions:

• Sensorimotor experiences are crucial for acquiring early, concrete word meanings.
• Later-acquired word meanings, particularly abstract ones, may rely on different learning experiences like linguistic input.
• Findings support a multi-representational model of lexical semantics, where word meanings are acquired through diverse experiences.
