False memories as a function of language proficiency: Differences between semantic and phonological processing.

Area of Science:

• Cognitive Psychology
• Psycholinguistics
• Neuroscience

Background:

• Verbal list-learning tasks reveal how language proficiency influences false memory rates.
• Existing theories like fuzzy trace theory and activation/monitoring framework explain reduced false memories with lower proficiency.
• Previous research primarily used semantic/associative lists.

Purpose of the Study:

• To investigate how language proficiency affects intrusion rates across different types of word lists (phonological, semantic, hybrid).
• To determine if less proficient speakers rely more on phonological than semantic information.

Main Methods:

• Compared false recall errors in native speakers, high-proficiency non-native speakers, and low-proficiency non-native speakers.
• Utilized phonological, semantic, and hybrid (phonological-semantic) verbal lists.
• Assessed language proficiency using subjective and objective measures.

Main Results:

• All proficiency groups exhibited false recall, but error patterns varied.
• High proficiency and native speakers showed similar error rates across list types, with the most errors on hybrid lists.
• Low proficiency speakers made significantly fewer semantic errors compared to hybrid and phonological errors.
• A hyper-additive effect was observed for hybrid lists across all groups.

Conclusions:

• Language proficiency broadly modulates false memory.
• Less proficient speakers may prioritize phonological over semantic information in memory recall.
• Findings challenge a one-size-fits-all explanation for false memory based solely on proficiency.
