Syntactic adaptation leads to updated knowledge for local structural frequencies.

Area of Science:

• Psycholinguistics
• Cognitive Science
• Computational Linguistics

Background:

• Syntactic adaptation demonstrates how readers adjust to temporarily ambiguous sentence structures after repeated exposure.
• The controversial claim suggests adaptation shifts expectations towards locally frequent structures, away from a priori more frequent ones.

Purpose of the Study:

• To replicate initial syntactic adaptation towards coordination and reduced relative garden-path structures.
• To investigate whether readers develop a preference for locally frequent structures over a priori more frequent ones.
• To determine if readers can rapidly update processing behaviors based on real-time statistical tracking.

Main Methods:

• Self-paced reading (SPR) was used in Experiment 1 to replicate adaptation to coordination garden-path structures.
• Experiments 2 and 3 combined SPR with sentence completion tasks to assess adaptation to coordination and reduced relative structures.
• These methods aimed to overcome the low reliability of SPR for detecting small adaptation effects.

Main Results:

• Experiment 1 replicated initial adaptation towards a coordination garden-path structure using SPR.
• Experiments 2 and 3 provided evidence for a preference for coordination and reduced relative structures over their a priori more frequent alternatives.
• The findings suggest participants track local structural statistics but may not rapidly update processing behaviors.

Conclusions:

• Participants demonstrate syntactic adaptation, favoring locally frequent structures.
• Real-time tracking of local structural statistics may occur during sentence processing.
• A potential limitation is the inability to rapidly use tracked statistics to update processing behaviors.
