Grammatical Aspect and Mental Activation of Implied Instruments: A Mouse-Tracking Study in Persian

Area of Science:

• Psycholinguistics
• Cognitive Science
• Linguistics

Background:

• Grammatical aspect describes an event's temporal unfolding (perfective/imperfective).
• Understanding how grammatical cues activate conceptual knowledge is crucial for language comprehension theories.

Purpose of the Study:

• To investigate the effect of grammatical aspect on the mental activation of instrument knowledge.
• To test whether imperfective aspect triggers the activation of implied instruments in Persian sentences.

Main Methods:

• Mouse tracking was used to analyze reaction times and response accuracy.
• Participants read sentences with manual action verbs in either perfective or imperfective aspect.
• They then judged the presence or absence of a visually presented implied instrument.

Main Results:

• The imperfective aspect condition showed a significant increase in incorrect "PRESENT" responses.
• Participants were less accurate in identifying the absence of the implied instrument.
• No significant differences in response times were observed between aspect conditions.

Conclusions:

• Grammatical aspect, specifically imperfective aspect, can bias event knowledge activation.
• Findings support embodied cognition theories, suggesting language comprehension involves simulating event knowledge.
• This research highlights the dynamic interplay between grammar and conceptual representation in language processing.
