Multisensory Experience

Covert speech is accompanied by a subjective multisensory experience with auditory and kinaesthetic components. An influential hypothesis states that these sensory percepts result from a simulation of the corresponding motor action that relies on the same internal models recruited for the control of overt speech. This simulationnist view raises the question of how it is possible to imagine speech without executing it. In this perspective, we discuss the possible role(s) played by motor inhibition during covert speech production. We suggest that considering covert speech as an inhibited form of overt speech maps naturally to the purported progressive internalisation of overt speech during childhood. However, we argue that the role of motor inhibition may differ widely across different forms of covert speech (e.g., condensed vs. expanded covert speech) and that considering this variety helps reconciling seemingly contradictory findings from the neuroimaging literature.

Rumination is known to be a predominantly verbal process and has been proposed to be considered as such as a dysfunctional form of inner speech (i.e., the silent production of words in one’s mind). On the other hand, research on the psychophysiology of inner speech revealed that the neural processes involved in overt and covert speech tend to be very similar. This is coherent with the idea that some forms of inner speech could be considered as a kind of simulation of overt speech, in the same way as imagined actions can be considered as the result of a simulation of the corresponding overt action (e.g., walking and imagined walking). In other words, the motor simulation hypothesis suggests that the speech motor system should be involved as well during inner speech production. The corollary hypothesis might be drawn, according to which the production of inner speech (and rumination) should be disrupted by a disruption of the speech motor system. We conducted a series of five studies aiming to probe the role of the speech motor system in rumination. Overall, our results highlight that although verbal rumination may be considered as a form of inner speech, it might not specifically involve the speech motor system. More precisely, we argue that rumination might be considered as a particularly strongly condensed form of inner speech that does not systematically involve fully specified articulatory features. We discuss these findings in relation to the habit-goal framework of depressive rumination and we discuss the implications of these findings for theories of inner speech production.

The Impact

The article summarizes the current state of understanding of the concept of inner speech and evaluates the role of the internal language in the speech generation process. First, the available definitions of inner speech are presented and its features are briefly characterised. Subsequently, the inner voice is compared to overt speech and the main differences between those two planes of speech: the internal and the external one are outlined. Since the aim of the paper is to show the role of inner speech in overt speech production, a speech generation model which coalesces Levelt‘s (1993) assumptions with the stratifi cational approach to language is presented. Different stages of linguistic processing are described and the impact of internal languaging on linguistic output is discussed. It is claimed that inner speech plays a threefold role in overt speech production: (1) provides an inter-nal draft for external speech, (2) is vital for the self-monitoring system, and (3) supports working memory. Any impairment in the functioning of inner speech may thus lead to speech errors and slips of the tongue phenomena.

The Brain

Much has been said at the symposium about the pre-eminent role of the brain in the continuing emergence of man. Tobias has spoken of its explosive enlargement during the last 1 Ma, and how much of its enlargement in individual ontogeny is postnatal. We are born before our brains are fully grown and ‘wired up ’. During our long adolescence we build up internal models of the outside world and of the relations of parts of our bodies to it and to one another. Neurons that are present at birth spread their dendrites and project axons which acquire their myelin sheaths, and establish innumerable contacts with other neurons, over the years. New connections are formed; genetically endowed ones are stamped in or blanked off. People born without arms may grow up to use their toes in skills that are normally manual. Tobias, Darlington and others have stressed the enormous survival value of adaptive behaviour and the ‘positive feedback’ relation between biological and cultural evolution. The latter, the unique product of the unprecedentedly rapid biological evolution of big brains, advances on a time scale unknown to biological evolution.

State Of The Field

We are amassing information about the role of the brain in speech production and the potential neural limitations that coincide with developmental stuttering at a fast rate. As such, it is difficult for many clinician-scientists who are interested in the neural correlates of stuttering to stay informed of the current state of the field. In this paper, I aim to inspire clinician-scientists to tackle hypothesis-driven research that is grounded in neurobiological theory. To this end, I will review the neuroanatomical structures, and their functions, which are implicated in speech production and then describe the relevant differences identified in these structures in people who stutter relative to their fluently speaking peers. I will conclude the paper with suggestions on directions of future research to facilitate the evolution of the field of neuroimaging of stuttering.

AbstractThe notion of semantic embodiment posits that concepts are represented in the same neural sensorimotor systems that were involved in their acquisition. However, evidence in support of embodied semantics – in particular the hypothesised contribution of motor and premotor cortex to the representation of action concepts – is varied. Here, we tested the hypothesis that, consistent with semantic embodiment, sensorimotor cortices will rapidly become active while healthy participants access the meaning of visually-presented motor and non-motor action verbs. Event-related potentials revealed early differential processing of motor and non-motor verbs (164-203ms) within distinct regions of cortex likely reflecting rapid cortical activation of differentially distributed semantic representations. However, we found no evidence for a specific role of sensorimotor cortices in supporting these representations. Moreover, we observed a later modulation of the alpha band (8-12Hz) from 555-785ms over central electrodes, with estimated generators within the left superior parietal lobule, which may reflect post-lexical activation of the object-directed features of the motor action concepts. In conclusion, we find no evidence for a specific role of sensorimotor cortices when healthy participants judge the meaning of visually-presented action verbs. However, the relative contribution of sensorimotor cortices to action comprehension may vary as a function of task goals.
