Unconscious effects of grammatical gender during object categorisation

Area of Science:

• Cognitive Psychology
• Neuroscience
• Linguistics

Background:

• The relationship between language and cognition is a key area of research.
• Grammatical gender systems in languages may influence how speakers perceive and categorize the world.
• Bilingualism offers a unique perspective to study language's impact on cognition.

Purpose of the Study:

• To investigate whether grammatical gender influences semantic categorization of objects in Spanish-English bilinguals.
• To explore if this influence occurs unconsciously, even in a monolingual language context.
• To examine the neural correlates of this phenomenon using event-related potentials (ERPs).

Main Methods:

• A semantic categorization task using picture triplets was administered to Spanish-English bilinguals and English monolinguals.
• Event-related potentials (ERPs) were recorded during the task.
• Picture names were manipulated such that the Spanish grammatical gender of the third item was either consistent or inconsistent with the first two, unbeknownst to participants.

Main Results:

• Behavioral data showed no significant priming effects related to semantic relatedness or gender consistency in either group.
• ERPs revealed a significant semantic priming effect in both bilingual and monolingual groups.
• Spanish-English bilinguals exhibited a unique negative modulation in ERPs associated with grammatical gender inconsistency, not observed in monolinguals.

Conclusions:

• Grammatical gender information is accessed spontaneously and unconsciously by bilinguals, even when not required by the task context.
• These findings provide evidence for linguistic relativity, specifically demonstrating how grammatical features of a language can shape cognitive processes.
• The study highlights the pervasive influence of language on perception and categorization, extending to unconscious grammatical properties.
