The action-sentence compatibility effect in third person action sentence comprehension

Area of Science:

• Cognitive Psychology
• Psycholinguistics
• Neuroscience

Background:

• The Action-sentence Compatibility Effect (ACE) reveals how motor system activation influences sentence comprehension.
• Previous research primarily focused on first-person perspective and simple action sentences.
• The role of object animacy and perspective priming in third-person action sentences remains less understood.

Purpose of the Study:

• To investigate the impact of object animacy on the ACE in third-person action sentences.
• To examine how perspective priming (agent vs. patient) modulates the ACE.
• To explore the flexibility of spatial simulation during the processing of third-person action sentences.

Main Methods:

• Utilized the sentence sensibility judgment paradigm to measure the ACE.
• Conducted three experiments manipulating object animacy (inanimate noun vs. personal name) and perspective priming (agent vs. patient).
• Analyzed the spatial compatibility effects along different axes (front-back, left-right) and action direction.

Main Results:

• ACE occurred along the front-back axis for inanimate objects.
• ACE appeared along the left-right axis for personal names.
• ACE aligned with action direction under agent priming but shifted to the opposite direction under patient priming.

Conclusions:

• Object animacy influences the spatial representation of actions in third-person sentences.
• Perspective priming dynamically modulates the ACE, indicating flexible simulation.
• Participants flexibly simulate action perspectives based on spatial cues and priming during sentence processing.
