Functional neuroanatomy of lexical access in contextually and visually guided spoken word production

Lexical access is commonly studied using bare picture naming, which is visually guided, but in real-life conversation, lexical access is more commonly contextually guided. In this fMRI study, we examined the underlying functional neuroanatomy of …

Neuroimaging evidence for shared lemma representations in speech production and comprehension

Lemma representations are thought to map the meaning of words to their sounds and vice-versa (Levelt et al., 1999). There is evidence using different methodologies that suggests that lemmas are localised in the middle portion of the left middle …

fMRI evidence for shared lemma representations in speech production and comprehension

On a prominent account, lemma representations map the meaning of words to their sounds and vice-versa, and are shared across production and comprehension (Levelt et al., 1999). A meta-analysis of word production studies suggests that lemmas are …

Investigating the Spatial and Temporal Components of Speech Production

The cognitive processes and neural mechanisms supporting language production have received considerably less research attention than those involved in language comprehension. This situation is partly attributable to the methodological challenges …

Attention for speaking: domain-general control from the anterior cingulate cortex in spoken word production

Accumulating evidence suggests that some degree of attentional control is required to regulate and monitor processes underlying speaking. Although progress has been made in delineating the neural substrates of the core language processes involved in …
