“…Therefore, there is a positive perception when someone uses hand movements. For cognitive processing, some studies have shown that these gestures can improve understanding and comprehension (Graham and Argyle, 1975;Riseborough, 1981;Hostetter, 2011;Kelly et al, 2015;Dargue et al, 2019), attention (Berger and Popelka, 1971), memory (Ianì and Bucciarelli, 2017;Clough and Duff, 2020), stimulate emotional reactions (Jackob et al, 2011), and clarify the discourse content (Holle and Gunter, 2007). According to the integrated system hypothesis (Kelly et al, 2010), gestures are part of an integrated system together with speech.…”

Some non-verbal cues, such as voice pitch and gestures, can influence the individual's emotional response to different messages. For this reason, non-verbal communication can be understood as the language of emotion, while the content is the language of ideas. But the research question here is what voice pitch and hand gesture strategies are more effective, attractive, and elicit a stronger emotional response. To answer this question, this study analyzes some pitch and hand gesture strategies in public discourses. In the experiment, 120 participants were exposed to different public presentations with three conditions for voice pitch (few, medium, and many variations) and three for hand gestures (smooth, medium, and strong intensity). Then, they rated the effectiveness and attractiveness levels and self-report arousal and valence while their emotional response was registered. Physiological arousal was measured with electrodermal activity (EDA) and valence with facial expression recognition. Participants perceived the medium pitch variations and the medium intensity of gestures as the most effective and attractive strategies with the highest self-reported arousal and valence. The combination that elicited the strongest autonomic arousal was medium pitch variations-strong gestures. Finally, the most positive emotional valence was for many pitch variations and medium gestures and the happiest for the combination many-strong.

“…Although the psychological interpretation of the obtained differences is not completely clear, we may cautiously suggest that the group with better clinical and functional outcome may engage some embodied cognition mechanisms in language production, such as a reliance on sensorimotor and visuospatial representations (Fogassi & Ferrari, 2007;. Another possible interpretation is an increased use of cospeech gestures by the more preserved patients that facilitates the planning and organization of utterances and lexical retrieval in the speaker as well as understanding in the listener (Clough & Duff, 2020). This is also supported by the data on impaired co-speech gestures in schizophrenia patients with severe negative symptoms and on the association between gesture performance and social functioning .…”

The analysis of heterogeneity in cognition and brain functioning in patients with schizophrenia seems promising for a deeper understanding of the disorder as well as treatment individualization. As language production and its executive control are disturbed in schizophrenia but may be heterogeneous in severity across patients and related to outcome, we aimed to compare the neuropsychological and neuroimaging measures related to these processes in patients with long-term schizophrenia spectrum disorders (mean illness duration of 20.3 ± 6.0 years) characterized by diverse clinical and functional statuses. Forty-four male patients and 18 age-comparable healthy males participated in the study. The participants performed four verbal fluency tasks (VF) and underwent resting-state fMRI. K-means clustering based on PANSS subscales and the PSP total score allocated patients to subgroups with better (S1; n = 15) and worse (S2; n = 29) outcomes. Between-group differences in VF performance and the whole-brain functional connectivity (FC) of the two seeds (the inferior frontal gyrus and the supplementary motor cortex) in the left hemisphere were analyzed. S1 demonstrated better performance in the letter and non-structured VF conditions compared to S2, and S1 did not differ from the healthy controls. Furthermore, S1 had higher FC between the left inferior frontal gyrus and a region in the left postcentral/precentral gyri and superior parietal lobule compared to S2 and the healthy controls. The latter finding merits attention in the context of resilience mechanisms in schizophrenia patients with more benign outcome

“…Nonetheless, there remains a decisive issue in the aphasia therapy literature: whilst evidence supports the use of behavioral therapy to improve aphasia, the mechanisms of therapy that promote change remain unclear (Brady et al, 2016). The review by Rose et al (2013) emphasizes that gestures should be included in clinical assessments in aphasia, and a recent review by Clough & Duff (2020) further emphasizes that a potent means of better understanding the mechanisms of successful behavioral therapy is to comprehensively evaluate multimodal communication (i.e., gesture alongside written and spoken language) in persons with neurogenic communication disorders.…”

Purpose In persons living with aphasia, we will explore the relationship between iconic gesture production during spontaneous speech and discourse task, spoken language, and demographic information. Method Employing the AphasiaBank database, we coded iconic gestures in 75 speakers with aphasia during two spoken discourse tasks: a procedural narrative, which involved participants telling the experimenter how to make a sandwich (“Sandwich”), and a picture sequence narrative, which had participants describe the picture sequence to the experimenter (“Window”). Forty-three produced a gesture during both tasks, and we further evaluate data from this subgroup as a more direct comparison between tasks. Results More iconic gestures, at a higher rate, were produced during the procedural narrative. For both tasks, there was a relationship between iconic gesture rate, modeled as iconic gestures per word, and metrics of language dysfluency extracted from the discourse task as well as a metric of fluency extracted from a standardized battery. Iconic gesture production was correlated with aphasia duration, which was driven by performance during only a single task (Window), but not with other demographic metrics, such as aphasia severity or age. We also provide preliminary evidence for task differences shown through the lens of two types of iconic gestures. Conclusions While speech-language pathologists have utilized gesture in therapy for poststroke aphasia, due to its possible facilitatory role in spoken language, there has been considerably less work in understanding how gesture differs across naturalistic tasks and how we can best utilize this information to better assess gesture in aphasia and improve multimodal treatment for aphasia. Furthermore, our results contribute to gesture theory, particularly, about the role of gesture across naturalistic tasks and its relationship with spoken language.
