How Memory Shapes Second-Language Vocabulary Acquisition in Primary School Learners

Area of Science:

• Developmental Psychology
• Cognitive Science
• Second Language Acquisition

Background:

• Current models of second-language (L2) vocabulary acquisition primarily focus on the phonological loop.
• The specific relationship between short-term memory and long-term memory in L2 learning is not well understood.
• Longitudinal studies are needed to explore memory's role in L2 growth during early education.

Purpose of the Study:

• To investigate the interplay between different memory systems and L2 vocabulary acquisition in primary school children.
• To identify specific short-term and long-term memory predictors of L2 vocabulary growth over a six-month period.
• To examine potential gender differences in memory-based L2 acquisition.

Main Methods:

• A longitudinal study design was employed with 82 primary school children (second and third graders).
• Participants' short-term memory and long-term memory abilities were assessed over six months.
• Delayed non-word recall and immediate repetition tasks were used to measure memory performance.

Main Results:

• Delayed non-word recall emerged as a significant predictor of L2 vocabulary acquisition, more so than immediate repetition.
• A notable primacy effect was observed, suggesting the importance of initial long-term consolidation.
• An interaction between gender and memory was found: females showed an initial advantage in L2 acquisition, but this diminished over time.

Conclusions:

• Long-term memory consolidation, indicated by delayed recall and primacy effects, is a crucial factor in L2 vocabulary acquisition models.
• The findings challenge the overemphasis on the phonological loop in current L2 acquisition theories.
• Cognitive strategies for L2 word learning may differ between genders, warranting further investigation.
