Orthographic autonomy hypothesis.

As mentioned in the introduction, a controversial issue in written production concerns the extent at which written production is dependent on phonology. We observed phonetic regularity effects and HD effects in writing Chinese, suggesting that the lexical and sublexical routes contributed to Chinese written production. This study provides evidence for the obligatory phonological mediation hypothesis. However, these results could not be regarded as evidence against the orthographic autonomy hypothesis, because this hypothesis did not deny the phonological role in written production. In line with this inference, some studies have shown evidence favoring the orthographic autonomy hypothesis [, ]. We suggested that a direct route from semantics to orthography and an indirect route from phonology to orthography (lexical and sublexical) were not exclusively incompatible with each other in the written production system.

The Autonomy of Lexical Orthography - Elsevier

We describe a brain-damaged subject, RR, who manifests superior written over spoken naming of concrete entities from a wide range of conceptual domains. His spoken naming difficulties are due pri-marily to an impairment of lexical-phonological processing, which implies that his successful written naming does not depend on prior access to the sound structures of words. His performance therefore provides further support for the “orthographic autonomy hypothesis, ” which maintains that written word production is not obligatorily mediated by phonological knowledge. The case of RR is especially inter-esting, however, because for him the dissociation between impaired spoken naming and relatively pre-served written naming is significantly greater for two categories of unique concrete entities that are lexicalised as proper nouns—specifically, famous faces and famous landmarks—than for five categories of nonunique (i.e., basic level) concrete entities that are lexicalised as common nouns—specifically, animals, fruits/vegetables, tools/utensils, musical instruments, and vehicles. Furthermore, RR’s predominant error types in the oral modality are different for the two types of stimuli: omissions for unique entities vs. semantic errors for nonunique entities. We consider two alternative explanations for RR’s extreme diffi-culty in producing the spoken forms of proper nouns: (1) a disconnection between the meanings of proper nouns and the corresponding word nodes in the phonological output lexicon; or (2) damage to the

By contrast, the orthographic autonomy hypothesis assumes that individuals can gain access to orthographic representation directly from meaning without phonological mediation.
