Twenty-five Years Of Research On Foreign Language Aptitude __link__ -

Contrary to the Critical Period Hypothesis’s strong version, research shows that older learners often outperform younger learners in initial explicit learning due to superior working memory and inductive ability. However, high aptitude in younger learners may manifest as superior phonological attainment in the long term (DeKeyser, 2020). Aptitude is thus not a static trait but interacts developmentally with age and learning context.

A quarter-century ago, foreign language aptitude was a dusty concept from the 1950s, dismissed by many educators as elitist or deterministic. Today, thanks to , we have a richer, more humane, and more pedagogically useful understanding.

What can we confidently say after a quarter-century of rigorous research?

Researchers linked ATIs to cognitive load theory. Learners with high WM capacity can handle the demands of implicit, input-rich environments, whereas learners with lower WM but strong analytical skills require explicit rule presentation to reduce cognitive load (Kormos, 2017). This has direct pedagogical implications: differentiated instruction based on aptitude profiles is not just desirable but potentially necessary.

Robinson argued that the traditional tests failed to differentiate between the cognitive demands of various learning tasks. He proposed the , suggesting that different learning conditions (e.g., implicit learning vs. explicit rule-searching) require different constellations of cognitive abilities. Research in this period identified several key "clusters" of aptitude:

: Carroll argues that aptitude is a relatively fixed cognitive trait, independent of motivation or general intelligence. Predictive Power : He demonstrates that while motivation determines someone will learn, aptitude predicts the

One of the most contentious yet fruitful developments in the last twenty-five years has been the blurring of lines between cognition and affect. Historically, aptitude (ability) was strictly separated from motivation ( : The talent for inferring rules and patterns

Carroll's research identified four stable cognitive factors that reliably predict how quickly and successfully an individual will learn a foreign language:

Key findings from 2000–2010 included:
