Category norm data and relationships with lexical frequency and typicality within verb semantic categories

Area of Science:

• Psycholinguistics
• Cognitive Psychology
• Neuroscience

Background:

• Category norm and typicality data are vital for understanding semantic memory.
• Existing data primarily focuses on nouns, limiting verb research.
• Verbs play a crucial role in sentence construction and meaning.

Purpose of the Study:

• To generate category norm and typicality data for verbs.
• To facilitate semantic memory research in linguistics, psychology, and aphasiology.
• To compare verb and noun data patterns.

Main Methods:

• Two experiments were conducted.
• Experiment 1: Participants listed verbs and nouns within semantic categories.
• Experiment 2: Participants rated verb typicality within categories.

Main Results:

• Fewer verbs were listed in verb categories compared to nouns in noun categories.
• Correlation patterns between production frequency, response rank, lexical frequency, and typicality were consistent for verbs and nouns.
• These patterns align with previous research on noun categories.

Conclusions:

• The study successfully expanded category norm and typicality data to include verbs.
• Verb and noun data exhibit consistent patterns, suggesting underlying similarities in semantic representation.
• The generated data will support future research on semantic memory and language processing.
