Some theories of lexical access in production locate the effect of lexical frequency at the
retrieval of a word's phonological characteristics, as opposed to the prior retrieval of a …

A recent theory of lexical access in picture naming maintains that all nonword errors are
generated during the retrieval of phonemic segments from the lexicon (Dell, Schwartz …

Background: Identifying the point of breakdown in people with aphasia with disorders of
word retrieval is not straightforward. Evidence has been sought from:(i) the nature of the …

Background: Perceived differences in word retrieval between naming and connected
speech contexts have been of clinical interest to clinicians and researchers for the last 50 …

Lexical access in language production, and particularly pathologies of lexical access, are
often investigated by examining errors in picture naming and word repetition. In this article …

Both normal and aphasic subjects produce picture naming errors that are semantically
related to the target. This study investigates the effects of different word properties on the …

Five computational models of lexical access during production are tested for their ability to
account for the distribution of aphasic picture-naming errors. The naming profiles (N= 14) …

Semantic errors produced by normal and aphasic speakers on a picture naming test were
examined for their phonological similarity to the targets they replaced. In both groups of …

This paper investigates the cognitive processes underlying picture naming and auditory
word repetition. In the two-step model of lexical access, both the semantic and phonological …

In models of word retrieval, it is common to differentiate lexical-semantic (word meaning)
and lexical-phonological (word form) levels. There has been considerable interest in the …
