Processing modifier-head agreement in reading: evidence for a delayed effect of agreement

Area of Science:

• Psycholinguistics
• Computational Linguistics
• Cognitive Science

Background:

• Modifier-head agreement is crucial for sentence comprehension.
• Finnish exhibits complex inflectional case systems.
• Understanding agreement processing sheds light on syntactic integration.

Purpose of the Study:

• To investigate the processing of Finnish modifier-head agreement.
• To determine the influence of inflectional case type (semantic vs. grammatical).
• To examine the role of phonological and morphological transparency in agreement effects.

Main Methods:

• Eye-tracking methodology was employed to record readers' eye movement patterns.
• Experiments manipulated agreement transparency (transparent vs. opaque).
• Case marking (unmarked vs. case-marked) was varied to assess its impact.

Main Results:

• A delayed agreement effect was observed, influencing target noun processing.
• This effect persisted across different transparency conditions.
• Results ruled out a simple modifier-presence effect.

Conclusions:

• Agreement effects occur at the syntactic integration level.
• Agreement processing does not influence lexical access.
• Finnish case marking plays a role in syntactic processing during reading.
