Distinguishing abstraction from abstractness: Specificity norms for 8,500 English words

Area of Science:

• Psycholinguistics
• Cognitive Psychology
• Neuroscience

Background:

• Psycholinguistic norms, such as concreteness, are vital for understanding word processing.
• Concreteness norms are widely used but may be confounded with word specificity.
• Concreteness and specificity might have differential impacts on lexical-semantic tasks.

Purpose of the Study:

• To collect and validate specificity scores for a large English word sample.
• To investigate the relationship between word specificity, concreteness, and lexical processing.
• To provide a valuable resource for future psycholinguistic and cognitive studies.

Main Methods:

• Collected specificity ratings from a large participant sample.
• Assessed the reliability and validity of the collected specificity scores.
• Analyzed the correlation between specificity, concreteness, and behavioral measures in lexical tasks.

Main Results:

• Specificity and concreteness are correlated but distinct dimensions.
• Specificity and concreteness exhibit different effects on lexical processing and memory.
• The study established a reliable and valid dataset of word specificity scores.

Conclusions:

• Word specificity is a critical psycholinguistic dimension separate from concreteness.
• The new specificity dataset will enhance future research on lexical-semantic processing.
• Distinguishing specificity from concreteness is essential for accurate modeling of language.
