Zertan datza 'the reliability' hon 'lexical level' respektu 'word-form level'?

Aurreko sarreran aipatu dugu ondorengo azalpena ganik Molinaro eta beste (2017):

Consequently, they [gaztelaniadun natiboek eta euskaldun natiboek] learned to efficiently predict based mainly on the regularities of their native language, adjusting their prediction mechanisms either to Spanish or to Basque. Predictors initially tuned to Spanish handle transparent and opaque items similarly during prediction, given the reliability of lexical-level [2. eta 3. divergentziak maila horretakoak lirake: lexiko-semantikoak] grammatical gender processing (Caffarra & Barber, 2015; Caffarra et al., 2014), while predictors initially tuned to Basque show more word-form effects [1. divergentzia: formal hutsa] even in an L2 when word-form (noun endings) cues are available. [Molinaro et al., 2017:71]

non azpimarratzen dén the reliability of lexical-level [maila horretakoak lirake 2. eta 3. divergentzia komunak] respektu word-form level [1. divergentzia gehigarria]. Sarrera honetan soilik nahi genuke zehaztu zértan datzan hóri reliability of lexical-level respektu word-form level. Ikus:

... it needs to be noted that although transparent endings [formalki, word-form level horretan] are valid cues for gender retrieval, they convey highly redundant information (Vigliocco and Franck, 2001). In  fact, while the lexical route always provides the correct gender of a noun (since all noun shave their gender value explicitly stored in the mental lexicon, Delfitto and Zamparelli, 2009), the form-based route does not. And, even when people cannot access information about word-form (Miozzo and Caramazza, 1997; Vigliocco et al., 1997), the grammatical gender can always be lexically recovered. [Caffarra & Barber, 2015:89]

Esan nahi baita ze, kontextu honetan, word-form level [aurreko sarreretan aipatutako 1. divergentzia gehigarri] horretako lan formal hori izango litzaké:

1.  partziala (ez du beti funtzionatzen),
2.  insegurua (nahiz-eta funtzionatu, ez du beti ondo funtzionatzen), eta
3.  highly redundant (ondo funtzionatuz gero ere). 

Horregatixe da inefizientea. [272] [>>>]
