“…These findings are in line with those of Kroenke, Mueller, Friederici, and Obrig (2013). Other studies have similarly found that PWA gesture during instances of WFD but have not found evidence of facilitation (e.g., Cocks et al, 2011;Cocks, Dipper, Pritchard, & Morgan, 2013;Kong, Law, & Cheung, 2018;.…”

The use and function of gestures in word-finding difficulties in aphasia Background: Gestures are spontaneous hand and arm movements that are part of everyday communication. The roles of gestures in communication are disputed. Most agree that they augment the information conveyed in speech. More contentiously, some argue that they facilitate speech, particularly when word finding difficulties occur. Exploring gestures in aphasia may further illuminate their role. Aims: This study explored the spontaneous use of gestures in the conversation of participants with aphasia (PWA) and neurologically healthy participants (NHP). It aimed to examine the facilitative role of gesture by determining whether gestures particularly accompanied word finding difficulties and whether or not those difficulties were resolved. Methods & Procedures: Spontaneous conversation data were collected from 20 PWA and 21 NHP. Video samples were analysed for gesture production, speech production, and word-finding difficulties. The first analysis examined whether the production of semantically rich gestures in these conversations was affected by whether the person had aphasia, and/or whether there were difficulties in the accompanying speech. The second analysis identified all word finding difficulties in the data and examined whether these were more likely to be resolved if accompanied by a gesture, again for both groups of participants. Outcomes & Results: Semantically rich gestures were frequently employed by both groups of participants, but with no effect of group. There was an effect of the accompanying speech, with gestures occurring most commonly alongside resolved word finding difficulties. An interaction showed that this was particularly the case for PWA. NHP, on the other hand, employed semantically rich gestures most frequently alongside fluent speech. The second analysis showed that word finding difficulties were common in both groups of participants. Unsurprisingly, these were more likely to be resolved for NHP than PWA. For both groups, resolution was more likely if the word finding difficulty was accompanied by a gesture. Conclusions: These findings shed light on the different functions of gesture within conversation. They highlight the importance of gesture during word finding difficulties, both in aphasic and neurologically healthy language, and suggest that gesture may facilitate word retrieval.

“…The next step in the analysis was to separate coding categories into those describing form or function. Form categories were defined as those describing the physical properties of a gesture, while function categories described how the gestures were used in an utterance (Kong et al 2019). Table 1 illustrates how different gesture classifications were classed as form or function.…”

“…Some authors have reported that people with aphasia are more likely to resolve their lexical retrieval difficulties when they are accompanied by semantically rich or iconic gestures (e.g., Akhavan et al 2018, Kistner et al 2019. However, others have observed that people with aphasia gesture during instances of word-retrieval difficulties, but have not found evidence that such gestures are facilitatory (e.g., Pritchard et al 2013, Kong et al 2019.

Background: People with aphasia rely on gesture more than healthy controls to get their message across, but use a limited range of gesture types. Gesture therapy is thus a potential avenue of intervention for people with aphasia. However, currently no gesture assessment evaluates how they use gesture. Such a tool could inform therapy targets and measure outcomes. In gesture research, many different coding categories are used to describe gesture forms and functions. These coding methods are prohibitively time-consuming to use in clinical practice. There is therefore a need for a 'quick and dirty' method of assessing gesture use. Aims: To investigate current practice among UK-based clinicians (speech and language therapists) in relation to gesture assessment and therapy, to synthesize gesture-coding frameworks used in aphasia research, to develop a gesture checklist based on the synthesized coding frameworks suitable for use in clinical practice, and to investigate the interrater reliability (IRR) of the checklist among experienced and unfamiliar users. Methods & Procedures: The research team synthesized seven gesture-coding frameworks and trialled three resulting prototype checklists at a co-design workshop with 20 clinicians. Attending clinicians were also consulted about their current clinical gesture practice using a questionnaire. A final City Gesture Checklist (CGC) was developed based upon outcomes and feedback from the workshop. The IRR of the CGC was evaluated between the research team and 11 further clinicians within a second workshop. Both groups used the CGC to count gestures in video clips of people with aphasia talking to a conversation partner. Main Contribution: A total of 18 workshop attendees completed the current practice questionnaire. Of these, 10 reported assessing gesture informally and five also used formal assessment. Gesture-coding synthesis highlighted six main categories of gesture form. Clinicians at the co-design workshop provided feedback on prototype checklists regarding the relevance and usability of the gesture categories, layout, use of images and instructions. A final version of the CGC was created incorporating their recommendations. The IRR for the CGC was moderate between both the researchers and clinicians. Conclusions & Implications: The CGC can be used to assess the types of gesture that people with aphasia produce. The IRR was moderate amongst both experienced users and new users who had received no training. Future research directions include investigating how to improve IRR, evaluating intra-rater reliability and sensitivity to change, and exploring use of the CGC in clinical practice.

Purpose: If language production is impaired, will gestures compensate? Evidence in favor of this prediction has often been argued to come from aphasia, but it remains contested. Here, we tested whether thought content not present in speech due to language impairment is manifested in gestures, in 20 people with dysfluent (Broca’s) aphasia, 20 people with fluent (Wernicke’s) aphasia, and 20 matched neurotypical controls. Method: A new annotation scheme was created distinguishing types of gestures and whether they co-occurred with fluent or dysfluent/absent speech and were temporally aligned in content with coproduced speech. Results: Across both aphasia types, noncontent (beat) gestures, which by their nature cannot compensate for lost speech content, constituted the greatest proportion of all types of gestures produced. Content (i.e., descriptive, referential, and metaphorical) gestures were largely coproduced with fluent rather than dysfluent speech and tended to be aligned with the content conveyed in speech. They also did not differ in quantity depending on whether the dysfluencies were eventually resolved or not. Neither aphasia severity nor comprehension ability had an impact on the total amount of content gesture produced in people with aphasia, which was instead positively correlated with speech fluency. Conclusions: Together, these results suggest that gestures are unlikely to have a role in compensating for linguistic deficits and to serve as a representational system conveying thought content independent of language. Surprisingly, aphasia rather is a model of how gesture and language are inherently integrated and aligned: Even when language is impaired, it remains the essential provider of content.
