“…In language comprehension, iconic gestures can disambiguate lexical meaning of homonyms (Holle & Gunter, 2007), can support comprehension when the speech is degraded (Drijvers & Özyürek, 2017;Holle et al, 2010) and can provide further details useful in building situational models (e.g. if a listener hears a speaker say 'and then I paid' whilst making a writing gesture, the listener can understand that the speaker paid using a cheque; Cocks et al, 2018). Drijvers and Özyürek (2017) further showed that iconic gestures play a more important role than visible mouth patterns in supporting spoken comprehension in noise, but that both cues together can contribute to comprehension.…”

In the last decade, a growing body of work has convincingly demonstrated that languages embed a certain degree of non-arbitrariness (mostly in the form of iconicity, namely the presence of imagistic links between linguistic form and meaning). Most of this previous work has been limited to assessing the degree (and role) of non-arbitrariness in the speech (for spoken languages) or manual components of signs (for sign languages). When approached in this way, non-arbitrariness is acknowledged but still considered to have little presence andpurpose, showing a diachronic movement towards more arbitrary forms. However, this perspective is limited as it does not take into account the situated nature of language use in face-to-face interactions, where language comprises categorical components of speech and signs, but also multimodal cues such as prosody, gestures, eye gaze etc. We review work concerning the role of context-dependent iconic and indexical cues in language acquisition and processing to demonstrate the pervasiveness of non-arbitrary multimodal cues in language use and we discuss their function. We then move to argue that the online omnipresence of multimodal non-arbitrary cues supports children and adults in dynamically developing situational models.

“…This hypothesis is primary supported by neuropsychological cases which reported that abnormal skilled learned purposive movements (limb apraxia) and language disorders (aphasia) are anatomically and functionally dissociable (Kertesz et al, 1984; Papagno et al, 1993; Heilman and Rothi, 2003). However, limb apraxia often co-occuring with Broca’s Aphasia (Albert et al, 2013) and difficulty in gesture-speech semantic integration was reported in aphasic patients (Cocks et al, 2009, 2018). Alongside clinical data, disrupting the activity in both left IFG and middle temporal gyrus (MTG) is found to impair gesture-speech integration (Zhao et al, 2018).…”

Spoken language is an innate ability of the human being and represents the most widespread mode of social communication. The ability to share concepts, intentions and feelings, and also to respond to what others are feeling/saying is crucial during social interactions. A growing body of evidence suggests that language evolved from manual gestures, gradually incorporating motor acts with vocal elements. In this evolutionary context, the human mirror mechanism (MM) would permit the passage from “doing something” to “communicating it to someone else.” In this perspective, the MM would mediate semantic processes being involved in both the execution and in the understanding of messages expressed by words or gestures. Thus, the recognition of action related words would activate somatosensory regions, reflecting the semantic grounding of these symbols in action information. Here, the role of the sensorimotor cortex and in general of the human MM on both language perception and understanding is addressed, focusing on recent studies on the integration between symbolic gestures and speech. We conclude documenting some evidence about MM in coding also the emotional aspects conveyed by manual, facial and body signals during communication, and how they act in concert with language to modulate other’s message comprehension and behavior, in line with an “embodied” and integrated view of social interaction.

“…39 A gestural approach to aphasia recovery is primarily endorsed as an adjunct to verbal communication and is promoted for its use as a compensatory word retrieval strategy. 35,36 The connection between hand-arm use and language is particularly salient to many in the Deaf community. Unlike hand gesture, Sign Language contains structured and expansive grammatical rules that share many of the same neural substrates as spoken language.…”

Aphasia is a debilitating language disorder that often follows stroke. It can affect any or all aspects of linguistic expression and comprehension, whether verbal, written, or gestural. Despite a growing understanding of the phenomenology of aphasia, new treatment paradigms are needed that directly target the underlying impairment. There are varying aphasia types and levels of severity, determined largely by the site and extent of stroke lesion as well as the degree of white matter integrity. 1 Herein, we will focus largely on the nonfluent or expressive poststroke aphasias, emphasizing how the affected anterior brain regions of the dominant hemisphere are interwoven with proximate cortical areas supporting upper limb and hand movement. Speech therapy is beneficial for patients with aphasia; however, no single treatment has proven most advantageous. 2 Many patients with aphasia experience chronic language deficits. Promising strategies to reduce permanent language deficits, such as pharmacological agents 3 and noninvasive brain stimulation 4 alone or in combination with speech therapy, have yet to be tested in appropriately powered clinical trials. One exciting perspective that is emerging from these multidisciplinary studies is the potential interaction between motor and aphasia recovery. 5,6 Increasingly, collateral effects on language production and comprehension have been reported as a result of the observation of movement. 7 Not coincidentally, given the close proximity of handarm and speech-language neural structures, in many patients with poststroke aphasia, the contralesional hand and arm are often simultaneously impaired. While the extent and limitations of hand-arm and speech-language cortical reciprocity remain under debate, it is likely that hand-arm movement and spoken language have at least a parallel, if not primary, relationship. 8 Nonetheless, stroke patients receiving speech-language therapy for aphasia are frequently seated during treatment, with hands and arms impassive. The use of hand-arm movement and exercise (eg, reaching, grasping, lifting) has not been sufficiently explored for direct use in aphasia rehabilitation. Objects that may be named in aphasia treatment, however, may also be simultaneously grasped. Manual tasks may be accompanied by verbal language, as they often are during activities of daily living. In this "Point-of-View" article, we provide an overview of data supporting hand-arm and language cortical reciprocity garnered from literature across multiple disciplines. Toward this aim, a PubMed search was conducted using multiple combinations of the terms "Limb," "Arm," "Gesture," "Speech," "Language" "Motor," "Action Verbs" and "Aphasia," yielding 652 articles. We excluded 384 articles due to their lack of relevance to our topic. For example, if the terms were combined incongruously or as part of a larger unrelated topic, these articles were excluded.
