“…Aphasia can impact spoken languages via expression and/or comprehension as well as reading, gesture, and writing. Adults with aphasia often display deficits in word retrieval, syntax, auditory attention span, processing, and memory (Caspari et al, 1998;Yu, 2010). Additionally, deficits with sensory function may result in auditory agnosia, visual agnosia, and visual field defects (Ardila& Hough, 2013).…”

“…One cognitive system believed to be involved with language processing in aphasia includes working memory. Different types of aphasia result from particular sites of damage affecting specific components of the language processing system as well as impacting working memory (Ardila, 2003;Baddeley, 2003;Caramazza, 1988;Caspari, et al, 1998;Friedmann & Gvion, 2003;Gutbrod, Cohen, Maier, & Meier, 1987).…”

“…Per Daneman and Carpenter (1980), this task significantly correlates with the measurement and prediction of reading comprehension when compared to simple digit span tasks. Thus, such a task is more efficient with measuring both processing and storage associated working memory (Caspari, et al, 1998).…”

“…WM is not a unitary process; additional cognitive functions associated with WM include: language comprehension, planning, reasoning, problem solving, consciousness, and second language acquisition (Ardila, 2003). More specifically, WM capacity can be defined as the total amount of resources utilized to support the processing and storage of information (Baddeley, 2003;Caspari et al, 1998;Daneman& Carpenter, 1980). It is hypothesized that people use a common, but limited resource pool relative to their WM capacity in which information is first processed and then temporarily stored until it is no longer needed.…”

“…Working memory is a system involved in the temporary storage and manipulation of information (Baddeley, 2003). It has been proposed that the ability of aphasic patients to understand language may be predicted based on their working memory capacity (Caspari, Parkinson, LaPointe, & Katz, 1998).…”

Formal thought disorder (FTD) refers to a psychopathological dimension characterized by disorganized and incoherent speech. Whether symptoms of FTD arise from aberrant processing in language-related regions or more general cognitive networks, however, remains debated. Here, we addressed this question by a quantitative meta-analysis of published functional neuroimaging studies on FTD. The revised Activation Likelihood Estimation (ALE) algorithm was used to test for convergent aberrant activation changes in 18 studies (30 experiments) investigating FTD, of which 17 studies comprised schizophrenia patients and one study healthy subjects administered to S-ketamine. Additionally, we analyzed task-dependent and task-independent (resting-state) functional connectivity (FC) of brain regions showing convergence in activation changes. Subsequent functional characterization was performed for the initial clusters and the delineated connectivity networks by reference to the BrainMap database. Consistent activation changes were found in the left superior temporal gyrus (STG) and two regions within the left posterior middle temporal gyrus (p-MTG), ventrally (vp-MTG) and dorsally (dp-MTG). Functional characterization revealed a prominent functional association of ensuing clusters from our ALE meta-analysis with language and speech processing, as well as auditory perception in STG and with social cognition in dp-MTG. FC analysis identified task-dependent and task-independent networks for all three seed regions, which were mainly related to language and speech processing, but showed additional involvement in higher order cognitive functions. Our findings suggest that FTD is mainly characterized by abnormal activation in brain regions of the left hemisphere that are associated with language and speech processing, but also extend to higher order cognitive functions.

Inner speech travels under many aliases: the inner voice, verbal thought, thinking in words, internal verbalization, “talking in your head,” the “little voice in the head,” and so on. It is both a familiar element of first‐person experience and a psychological phenomenon whose complex cognitive components and distributed neural bases are increasingly well understood. There is evidence that inner speech plays a variety of cognitive roles, from enabling abstract thought, to supporting metacognition, memory, and executive function. One active area of controversy concerns the relation of inner speech to auditory verbal hallucinations (AVHs) in schizophrenia, with a common proposal being that sufferers of AVH misidentify their own inner speech as being generated by someone else. Recently, researchers have used artificial intelligence to translate the neural and neuromuscular signatures of inner speech into corresponding outer speech signals, laying the groundwork for a variety of new applications and interventions.
