Language as a cue for social categorization in bilingual communities

Area of Science:

• Psychology
• Sociolinguistics
• Cognitive Science

Background:

• Social categorization is a fundamental cognitive process.
• Language is a key social identity marker.
• The automaticity of language-based social categorization in bilinguals remains under-investigated.

Purpose of the Study:

• To investigate if language acts as a social categorization dimension among bilingual individuals.
• To determine if this categorization occurs even when languages coexist within the same sociolinguistic context.

Main Methods:

• Utilized a 'Who said what?' memory confusion paradigm with bilingual participants from the Basque Country (Spain) and Veneto (Italy).
• Participants encoded faces paired with auditory sentences in two languages (Spanish/Basque and Italian/Venetian).
• Tested recall accuracy by presenting sentences and asking participants to identify the associated face.

Main Results:

• High error rates were observed in identifying faces associated with spoken sentences.
• Crucially, participants were significantly more likely to confuse faces from the same language category than from different language categories.
• This indicates a strong tendency to group individuals based on the language they speak.

Conclusions:

• Language serves as an automatic dimension for social categorization in bilingual individuals.
• This process occurs irrespective of the languages coexisting within a single sociolinguistic environment.
• Findings highlight the pervasive influence of language on social perception and group formation.
