In different aspects of linguistic competence,proponents and opponents of the CPH also share different views.In terms of pronunciation(native-like accent) competence,proponents of the CPH argue that younger starters are better than older starters;while opponents of the CPH hold that some older starters have reached high levels of native-like accent proficiency after puberty.With regard to morphology and syntax(grammar) competence,proponents of the CPH believe that universal grammar is accessible for younger starters at a critical period while older starters seem to gradually lose this innate language-acquisition device,which causes them to be less successful in the acquisition of grammar.However,opponents of CPH claim that there is no strong empirical evidence which indicates that older starters do not have access to universal grammar after puberty.Therefore,it is still uncertain whether younger starters do have better grammatical competence than older starters,since whether or not universal grammar continues to be available as a support for language acquisition after puberty is still doubtful.

In terms of pronunciation (native-like accent) competence, proponents of the CPH argue that younger starters are better than older starters; while opponents of the CPH hold that some older starters have reached high levels of native-like accent proficiency after puberty. Whith regard to morphology and syntax (grammar) competence, proponents of the CPH believe that universal grammar is accessible for younger starters at a critical period while older starters seem to These lose them innate language-acquisition device, which causes them to be less successful in the acquisition of grammar. However, opponents of CPH claim that there is no strong empirical evidence that indicates that older starters do not have access to universal grammar after puberty. Therefore, it is still uncertain whether younger starters do have better grammatical competence than older starters, since whether or not uni versal grammar continues to be available as a support for language acquisition after puberty is still doubtful.
