Descriptive norms for 245 Italian idiomatic expressions

Area of Science:

• Psycholinguistics
• Cognitive Psychology
• Linguistics

Background:

• Idiomatic expressions are crucial for fluent language use.
• Normative data on Italian idioms is scarce.
• Understanding idiom processing aids in cognitive research.

Purpose of the Study:

• To establish descriptive normative measures for 245 Italian verbal idiomatic expressions.
• To investigate psycholinguistic dimensions of idioms, including knowledge, familiarity, age of acquisition, predictability, syntactic flexibility, literality, and compositionality.
• To provide a freely accessible database for researchers.

Main Methods:

• Collected normative data on 245 Italian verbal idiomatic expressions.
• Assessed variables: Length, Knowledge, Familiarity, Age of Acquisition, Predictability, Syntactic flexibility, Literality, and Compositionality.
• Evaluated syntactic flexibility using five operations: adverb insertion, adjective insertion, left dislocation, passive, and movement.

Main Results:

• Reported descriptive normative measures for all 245 Italian verbal idioms.
• Detailed psycholinguistic relevance, measures, and intercorrelations of the assessed dimensions.
• Made databases available for download via the Psychonomic Society Web archive.

Conclusions:

• The study provides a comprehensive normative dataset for Italian verbal idioms.
• The findings contribute to understanding the psycholinguistics of idiom processing.
• The accessible database facilitates future research in psycholinguistics and language acquisition.
