Evidence quality · No study behind this claim is a peer-reviewed article with a DOI: it rests on an ERIC document (a report, conference paper or thesis). It is kept because 4 design pages cite it; treat it as a lead to check, not an established finding.

Subclaims¶

q2 i? If older people remain healthy, their intellectual abilities and skills do not decline, and no age-related differences in learning ability have been demonstrated among adults of different ages. → Schleppegrell 1987

Evidence¶

Schleppegrell 1987¶

Schleppegrell, Mary. (1987). The Older Language Learner. ERIC Clearinghouse on Languages and Linguistics, Washington DC. https://eric.ed.gov/?id=ED287313

q2 · i? · review · r1

The digest reports, citing Ostwald and Williams, studies on aging showing that "learning ability does not decline with age" when older people remain healthy. It adds that no age-related differences in learning ability have been demonstrated among adults of different ages. No effect sizes are printed.

"Studies on aging have demonstrated that learning ability does not decline with age. If older people remain healthy, their intellectual abilities and skills do not decline"

Studies bearing on this claim¶

Can older learners learn a new language as well as younger ones, and what teaching suits them? This table gathers the studies behind this claim and the 7 narrower claims that bear on it: 5 distinct studies (4 review, 1 design), q1–q2, 0 of 5 with an effect size coded. One row per study, codes as each entry records them; no effect is averaged and no verdict is drawn. Built by scripts/synthesize_claim.py from eval/synthesis/; a row that looks wrong is fixed on the claim it comes from.

Discussion¶

Learner Variables¶

• Age and Developmental Stage — predictor: learners who differ on it differ in outcomes

Related Claims¶

• A practitioner digest asserts, without cited studies, that no research evidence suggests older adults cannot succeed in learning another language — possibly the same claim (merge candidate)
• No age is optimal or critical for second language learning, and older learners can benefit more from cognitive approaches — related
• Aging does not substantially reduce informal learning participation, though preference shifts from courses to self-directed learning — related
• Older adults can think as divergently as young adults but do so at a slower rate and require more time — related
• Adult learners generally find pronunciation more difficult than children and are unlikely to achieve native-like pronunciation, though experience and self-monitoring offset this somewhat — related
• Combined with adolescent data, the lifespan profile of perceptual metacognitive efficiency is an inverted-U — related
• Perceptual metacognitive efficiency declines with age in healthy adults aged 18–84, even when task performance is controlled — reports the opposite
• Federally-funded adult ESL programs and citizenship classes largely exclude older beginner immigrants because instruction is designed for workforce-bound younger adults — reports the opposite
• Instructional modifications that lower barriers are optional supports for younger resilient learners but may be necessary for older beginners, pre-literate students, and learners dealing with trauma or disabilities — reports the opposite
• When relevant knowledge can be drawn upon, age trends in performance can reverse, with older adults outperforming younger adults on crossword puzzles — related
• Common language teaching methods such as oral drills, memorization, and fast-paced competitive activities disadvantage older learners — reports the opposite
