Semantic Information and the Syntax of Propositional Attitude Verbs

Area of Science:

• Linguistics
• Psycholinguistics
• Cognitive Science

Background:

• Propositional attitude verbs (e.g., think, want) exhibit complex syntactic, semantic, and pragmatic properties.
• Understanding these properties and their interactions is challenging for theoretical linguistics and language acquisition research.

Purpose of the Study:

• To investigate the extent to which semantic and pragmatic properties of propositional attitude verbs can be inferred from their syntactic distributions.
• To quantitatively assess the relationship between syntactic distributions and semantic/pragmatic properties.

Main Methods:

• Experiment 1: Assessed syntactic distributions of 30 propositional attitude verbs via acceptability judgments.
• Experiments 2a & 2b: Measured semantic similarity using a generalized semantic discrimination task and a Likert scale task.
• Analyses compared experimental data to existing literature and directly correlated syntactic and semantic judgments.

Main Results:

• Syntactic distributions provide fine-grained information about the semantics of propositional attitude verbs.
• Both qualitative (discrete) and quantitative (continuous) classifications of verb semantics can be derived from syntactic data.
• Experimental results align with and refine existing classifications from linguistic literature.

Conclusions:

• Syntactic distributions are a rich source for understanding the semantics of propositional attitude verbs.
• Behavioral experiments offer a quantitative approach to linking syntax and semantics in language.
• This research bridges theoretical linguistic classifications with experimentally derived semantic data.
