Study Overview

  • Investigation of the role of short-term memory (STM) and working memory (WM) in accomplished multilinguals.

  • Participants: 28 accomplished multilinguals vs. 36 mainstream philology students.

Instruments Used

  1. Wechsler Intelligence Scale Subtests:

    • Digit Span

    • Digit-Symbol Coding

    • Arithmetic (Memory and Resistance to Distraction Index)

  2. Modern Language Aptitude Test (MLAT):

    • Part I: Number Learning

    • Part V: Paired Associates

  3. Verbal IQ, Nonverbal IQ, General IQ Measures

  4. Polish Reading Span (PRSPAN) Test

Findings

  • Higher STM and WM abilities in accomplished multilinguals compared to mainstream philology students.

  • Implication of the phonological loop and central executive components of WM in determining foreign language learning outcomes.

Literature Review

Memory in Second Language Acquisition (SLA)

  • Importance of working memory in determining outcomes of foreign language learning (Dörnyei, 2005; Ellis, 2001).

  • Lack of research on memory abilities in accomplished multilinguals.

Definitions

  • Short-term Memory (STM): Static memory held for less than 20 seconds.

  • Working Memory (WM): Temporary storage and manipulation of information essential for cognitive tasks (Baddeley, 2003).

    • WM is described as “memory at work” (Conway et al., 2008).

    • Components of WM:

    1. Phonological Loop

    2. Visuospatial Sketchpad

    3. Central Executive (supervisory attention system)

    4. Episodic Buffer (Baddeley, 2000).

Role of WM in Cognitive Abilities

  • WM capacity affects varied cognitive tasks including language learning, reasoning, and comprehension (Kane et al., 2008).

  • Variability in WM performance can be attributed to:

    • Mental speed

    • Executive attention

    • Attention capability has implications for cognitive abilities (Kane et al., 2008).

Relationship Among STM, WM, and General Intelligence

  • Engle et al. (1999) proposed that WM and STM are separate but correlated (correlation of .68).

  • Kane et al. (2008) argued that quality of WM measures is debated, with suggestions that some STM tasks measure elements of executive attention.

Role of Memory in Foreign Language Learning

Significance of WM in Language Success

  • Research suggests WM, particularly the phonological loop, is essential for language acquisition (Baddeley, 2003).

    • Poor memory correlates with poor language skill development (Baddeley et al., 1998).

  • Evidence indicates that exceptional language learners have highly efficient phonological loops.

The Processing Stage Model of Aptitude (Skehan, 1998)

  1. Noticing Phase: Attention and rehearsal of language aspects.

  2. Patterning Phase: Detection and manipulation of language patterns.

  3. Controlling Stage: Automating language use through retrieval from memory.

  4. Lexicalizing Phase: Enhancing rapid access to linguistic knowledge.

Memory as a Key Component of Language Aptitude

  • WM is a central component in language processing (Miyake and Friedman, 1998).

  • Connection between WM capacity and learning outcomes (Dörnyei, 2005).

Study Methodology

Participants

  • Accomplished Multilinguals: 28 students, C1/C2 proficiency in at least one foreign language.

  • Mainstream Philology Students: 36 first-year English philology students, intermediate proficiency.

Data Collection and Analysis

  • Testing included MLAT, PRSPAN, WAIS-R subtests over 16 months.

  • Statistical analysis via Pearson correlation, descriptive stats, and ANOVA.

Results

  • Descriptive Statistics:

    • High abilities in memory with significant differences (Hypothesis 1 confirmed).

    • Accomplished multilinguals significantly outperform mainstream students in STM and WM tests.

Findings Summary

  • Higher scores noted in various tests for accomplished multilinguals:

    • MLAT and PRSPAN scores were markedly higher, confirming their linguistic strengths.

    • Correlations across various measures were positive and significant, reinforcing existing research.

Conclusion

  • Results confirm superior memory abilities among accomplished multilinguals.

  • Suggests intertwined relationship between WM capacity and language learning success, necessitating further investigation into individual differences in language learning among diverse populations (Robinson, 2003).

  1. Working Memory (WM) is defined as the temporary storage and manipulation of information that is essential for various cognitive tasks. It is often described as “memory at work” (Conway et al., 2008) and includes components like the Phonological Loop, Visuospatial Sketchpad, Central Executive, and Episodic Buffer.

  2. Short-term Memory (STM) is static memory held for less than 20 seconds.

  3. Individuals with greater Working Memory (WM) capacity perform better on varied cognitive tasks, including language learning, reasoning, and comprehension (Kane et al., 2008).

  4. According to Skehan's (1998) Processing Stage Model of Aptitude, the four stages of Second Language Acquisition (SLA) are:

    • Noticing Phase: This stage involves paying attention to and rehearsing specific aspects of the language.

    • Patterning Phase: In this phase, learners detect and manipulate language patterns.

    • Controlling Stage: This stage focuses on automating language use through retrieval from memory.

    • Lexicalizing Phase: This final phase enhances rapid access to linguistic knowledge.
