“…The maturational account was challenged by evidence from numerous findings that demonstrated a gradual decline with age in L2 learning post-puberty, rather than an abrupt cut off age point, as was proposed by the critical period hypothesis (Bialystok, 1997;Marinova-Todd, Marshall, & Snow, 2000, 2001).
