“…Conversely, it was also noted that activation in the planum temporale and inferior parietal lobe was higher during covert than overt production of sentences (Andreatta et al, 2010) and during covert (imagined) than overt singing (Kleber et al, 2007). This suggests that activation in these temporo-parietal regions might be related to the sensorimotor circuits that maintain sound representations for the production of speech and song (Koelsch et al, 2009).…”

A review and synthesis of the first 20years of PET and fMRI studies of heard speech, spoken language and reading

The anatomy of language has been investigated with PET or fMRI for more than 20 years. Here I attempt to provide an overview of the brain areas associated with heard speech, speech production and reading. The conclusions of many hundreds of studies were considered, grouped according to the type of processing, and reported in the order that they were published. Many findings have been replicated time and time again leading to some consistent and undisputable conclusions. These are summarised in an anatomical model that indicates the location of the language areas and the most consistent functions that have been assigned to them. The implications for cognitive models of language processing are also considered. In particular, a distinction can be made between processes that are localized to specific structures (e.g. sensory and motor processing) and processes where specialisation arises in the distributed pattern of activation over many different areas that each participate in multiple functions. For example, phonological processing of heard speech is supported by the functional integration of auditory processing and articulation; and orthographic processing is supported by the functional integration of visual processing, articulation and semantics. Future studies will undoubtedly be able to improve the spatial precision with which functional regions can be dissociated but the greatest challenge will be to understand how different brain regions interact with one another in their attempts to comprehend and produce language.

“…In the Font task, there was actually no explicit requirement for constructing a coherent semantic representation. While in the SEM task, the participants may use a specific response strategy, terminating semantic processing (and related working memory processing) before the sentence ended as soon as they detected the incongruence (Andreatta et al, 2010). Consequently, the cognitive processes and the modulation effect in SEM were absent.…”

The anterior left inferior frontal gyrus contributes to semantic unification

a b s t r a c t a r t i c l e i n f oSemantic unification, the process by which small blocks of semantic information are combined into a coherent utterance, has been studied with various types of tasks. However, whether the brain activations reported in these studies are attributed to semantic unification per se or to other task-induced concomitant processes still remains unclear. The neural basis for semantic unification in sentence comprehension was examined using event-related potentials (ERP) and functional Magnetic Resonance Imaging (fMRI). The semantic unification load was manipulated by varying the goodness of fit between a critical word and its preceding context (in high cloze, low cloze and violation sentences). The sentences were presented in a serial visual presentation mode. The participants were asked to perform one of three tasks: semantic congruency judgment (SEM), silent reading for comprehension (READ), or font size judgment (FONT), in separate sessions. The ERP results showed a similar N400 amplitude modulation by the semantic unification load across all of the three tasks. The brain activations associated with the semantic unification load were found in the anterior left inferior frontal gyrus (aLIFG) in the FONT task and in a widespread set of regions in the other two tasks. These results suggest that the aLIFG activation reflects a semantic unification, which is different from other brain activations that may reflect task-specific strategic processing.

“…Based on evidence from neuropsychological studies, it has been argued that verbal working memory processes rely on a separate neural network to speech production ( Baddeley & Logie, 1999 ; see The Neuropsychology of Inner Speech). However, most recent studies have implicated similar and overlapping networks for verbal working memory maintenance and overt speech in fronto-temporal regions, along with recruitment of the cerebellum ( Marvel & Desmond, 2012 ) and posterior temporoparietal structures such as the planum temporale and inferior parietal lobule ( Andreatta, Stemple, Joshi, & Jiang, 2010 ). While the cerebellum is thought to support motor processes involved in verbal rehearsal ( Marvel & Desmond, 2010 ), the involvement of temporoparietal cortex has been proposed to reflect recruitment from long-term memory of phonological representations to support working memory maintenance ( Price, 2012 ).…”

Inner speech—also known as covert speech or verbal thinking—has been implicated in theories of cognitive development, speech monitoring, executive function, and psychopathology. Despite a growing body of knowledge on its phenomenology, development, and function, approaches to the scientific study of inner speech have remained diffuse and largely unintegrated. This review examines prominent theoretical approaches to inner speech and methodological challenges in its study, before reviewing current evidence on inner speech in children and adults from both typical and atypical populations. We conclude by considering prospects for an integrated cognitive science of inner speech, and present a multicomponent model of the phenomenon informed by developmental, cognitive, and psycholinguistic considerations. Despite its variability among individuals and across the life span, inner speech appears to perform significant functions in human cognition, which in some cases reflect its developmental origins and its sharing of resources with other cognitive processes.
