Long-term cumulative structural priming persists for (at least) one week.

Area of Science:

• Psycholinguistics
• Cognitive Psychology
• Language Production

Background:

• Previous research has identified cumulative structural priming effects in language production.
• These effects describe how exposure to a particular sentence structure influences the likelihood of using that structure again.

Purpose of the Study:

• To investigate the long-term persistence of cumulative structural priming effects.
• To determine if priming effects established in one session endure for a week.

Main Methods:

• Participants completed written sentence stems designed to elicit either the double object or prepositional object construction.
• Participants returned for a second experimental session one week after the initial session.
• Performance in the second session was analyzed to assess the persistence of priming from the first session.

Main Results:

• The biases established in the first experimental session significantly affected participants' performance in the second session.
• The cumulative structural priming effect demonstrated persistence over the one-week interval.
• This indicates that short-term priming effects can have lasting impacts on language production.

Conclusions:

• Cumulative structural priming effects are not transient and can persist for at least a week.
• These findings have implications for understanding the mechanisms underlying language production and memory.
• The persistence of priming suggests robust encoding and retrieval processes in the language system.
