Résumé
Résumé
Studies employing primed lexical decision tasks have revealed morphological facilitation
effects in children and young adults. It is unknown if this effect is preserved or diminished
in older adults. In fact, only few studies have investigated age-related changes in
morphological processing and results are inconsistent across studies. To address this
issue, we investigated inflection morphology compared to orthographic and semantic
processing in young and older adults. Twenty-six adults aged 60–85 and 22 younger
adults aged 19–28 participated. We probed verb recognition using a sandwich-masked
primed lexical decision paradigm. We investigated lexical decision using different prime
presentation times (PPTs) (33, 66, and 150 ms), and prime types with priming conditions
involving orthographic (e.g., cassis—CASSE ‘blackcurrant—break’), regular inflection
morphological (cassait—CASSE ‘broke—break’), and semantic primes (brise—CASSE
‘break—break’) and their controls, while measuring response accuracy and reaction
times. Response accuracy analyses revealed that older participants performed at ceiling
on the lexical decision task, and that accuracy levels were higher compared to young
adults. Reaction-time data revealed effects of age group, priming condition, and an
interaction of age group and morphological priming, but no PPT effects. Both young
and older adults presented a significant facilitation effect (reduced reaction times) in the
orthographic and morphological priming conditions. No semantic effects were observed
in either group. Younger adults also showed a significantly stronger morphological
priming effect, while older adults showed no difference between orthographic and
morphological priming when comparing priming magnitudes. These findings suggest
(1) that regular inflectional morphological processing benefits lexical access in younger
French adults, confirming studies in other languages, and (2) that this advantage is
reduced at older ages.
