It is at this point of cognitive overload when individuals pursuing other creative tasks would typically shift the burden and externalise some of their thinking. How do successful verbal improvisers manage without shifting some of their workload into an external space? We argue in this paper that the improviser makes use of what is, quite literally, to hand. Ninety participants were asked to take part in a one-to-one improvisation task and a control task, order counterbalanced, in which they were engaged in a brief conversation to elicit every day speech. Participants' gestures were analysed in both conditions and improvisations rated for quality. As predicted, participants gestured significantly more in the improvisation condition. An analysis of gesture type revealed that improvising elicited greater iconic and deictic gestures, whereas everyday speech was more likely to be accompanied by self-adaptor gestures. Gesture rate was related to the quality of the improvisation, with both the strongest and weakest improvisers producing the most gestures. These gestures revealed the extent to which participants used gestures to facilitate the improvisation task. The strongest improvisers elicited a higher gesture rate for iconic and beat gestures, while weakest improvisers produced more gestures in reference to the abstract, improvisation object. Findings are discussed in relation to the idea that gesture can facilitate performance in verbal improvisation.Peer reviewedFinal Accepted Versio

The Goldsmiths Dance Sophistication Index (Gold-DSI): A Psychometric Tool to Assess Individual Differences in Dance Experience

Dance has become an important topic for research in empirical aesthetics, social and motor cognition, and as an intervention for neurodegenerative and neurodevelopmental disorders. Despite the growing scientific interest in dance, no standardised psychometric instrument exists to assess people’s dance experience. Here, we introduce the Goldsmiths Dance Sophistication Index (Gold-DSI), a 26-item questionnaire to measure individual differences in participatory and observational dance experience on a continuous scale. The Gold-DSI was developed in three stages: In the first stage a set of 76 items was generated by adapting questions from the Goldsmiths Musical Sophistication Index (Müllensiefen et al., 2014), and as part of a stakeholder workshop using a grounded theory approach. The second stage focused on item reduction. Using a large-scale online survey (N=424) , hierarchical factor analysis was used to fit a model comprising of one general and six secondary factors (28 items in total). In stage three, six new items were added to specifically capture individual differences in dance observation. We then collected data from two samples for final model estimation (N=127) and evaluation (N=190). The final version of the Gold-DSI comprises 26 items; 20 items relate to one general factor that captures experience in dance participation. This includes four secondary factors: Body Awareness, Social Dancing, Urge to Dance, and Dance Training. A further six items separately measure experience in dance observation. In sum, the Gold-DSI provides a brief, standardised and continuous assessment of doing, watching and knowing about dance

Music and Metronomes Differentially Impact Motor Timing in People with and without Parkinson's Disease: Effects of Slow, Medium, and Fast Tempi on Entrainment and Synchronization Performances in Finger Tapping, Toe Tapping, and Stepping on the Spot Tasks

However, the way in which different auditory cues and types of movements affect entrainment, synchronization and pacing stability has not been directly compared in different aged people with and without Parkinson's. Therefore, this study compared music and metronomes (cue types) in finger tapping, toe tapping and stepping on the spot tasks to explore the potential of RAS training for general use.Methods: Participants (aged 18-78 years) included people with Parkinson’s (n=30, Hoehn & Yahr Mean=1.78), Older (n=26), and Younger adult controls (n=36), as age may effect motor timing. Timed motor production was assessed using an extended synchronization-continuation task in cue type and movement conditions for slow, medium and fast tempi (81, 116 and 140 mean beats-per-minute respectively).Results: Analyses revealed main effects of cue and movement type but no between group interactions, suggesting no differences in motor timing between people with Parkinson's and controls. Music supported entrainment better than metronome in medium and fast tempi, and stepping on the spot enabled better entrainment and less asynchrony, as well as more stable pacing compared to tapping in medium and fast tempi. Age was not confirmed as a factor and no differences were observed in slow tempo.Conclusion: This is the first study to directly compare how different external auditory cues and movement types affect motor timing. The music and the stepping enabled participants to maintain entrainment once the external pacing cue ceased, suggesting endogenous mechanisms continued to regulate the movements. The superior performance of stepping on the spot suggests embodied entrainment can occur during continuous movement, and this may be related to emergent timing in tempi above 600 ms. These findings can be applied therapeutically to manage and improve adaptive behaviours for people with Parkinson’s.Peer reviewe

Bases expert statement on the use of music for movement among people with Parkinson's

First published in The Sport and Exercise Scientist, February 2020, Issue 63. Published by the British Association of Sport and Exercise Sciences – www.bases.org.uk.Music is an artistic auditory stimulus that unfolds over time. It can prime specific actions and prompt engagement in physical activity as well as heighten motivation during motor tasks (Karageorghis, 2020). Contrastingly, it can be used to downregulate arousal to facilitate the transition from an active to a sedentary state or to ameliorate anxiety. In therapeutic applications, musical features such as rhythm, melody and harmony have been shown to elicit psychological and physiological changes (Thaut & Hoemberg, 2014). Parkinson’s is a degenerative neurological condition in which the loss of dopamine neurons results in impaired initiation and control of movement, with common symptoms including tremor, postural instability and gait disturbance. There are also non-motor effects that include apathy, anxiety and depression. Medication does not alleviate all manifestations of the condition and there is presently no known cure (Obeso et al., 2017). It is notable that people with Parkinson’s are estimated to be 30% less active than agematched peers (Ramaswamy et al., 2018). Nonetheless, evidence is emerging that a range of exercise-based and social activities that involve musical engagement can serve to address the common symptoms and enhance quality of life (Thaut & Hoemberg, 2014). This statement brings together an international interdisciplinary team to outline what is known about music-related applications for people with Parkinson’s, and to provide recommendations for exercise and health practitioners.Peer reviewe

However, music is more commonly associated with an entrained bodily response, such as toe tapping, or dancing. Here we report an experimental procedure that was designed to bridge the gap between timing and intervention studies by directly comparing the effects of metronome and musical cue types on motor timing abilities across the three naturalistic voluntary actions of finger tapping, toe tapping, and stepping on the spot as a simplified case of whole body movement. Both pacing cues were presented at slow, medium, and fast tempi. The findings suggested that the task of stepping on the spot enabled better timing performances than tapping both in younger and older adults (75+). Timing performances followed an inverse U shape with best performances observed in the medium tempi that were set close to the spontaneous motor tempo in each movement type. Finally, music provided an entrainment effect in addition to pace setting that enabled better motor timing and greater stability than classically reported using a metronome. By applying time-stamp analyses to kinetic data, we demonstrate that tapping and stepping engage different timing modes. This work details the importance of translational research for a better understanding of motor timing. It offers a simple procedure that strengthens the validity of applying academic work and contributes in knowledge towards a wide range of therapeutic interventions.Peer reviewe

A reconnaissance survey of farmers’ awareness of hypomagnesaemic tetany in UK cattle and sheep farms

Hypomagnesaemic tetany (HypoMgT) in ruminants is a physiological disorder caused by inadequate intake or impaired absorption of magnesium (Mg) in the gut. If it is not detected and treated in time, HypoMgT can cause the death of the affected animal. A semi-structured questionnaire survey was conducted from July 2016–2017 to assess farmers’ awareness of HypoMgT in cattle and sheep in the UK. The questionnaire was distributed to farmers at farm business events and agricultural shows, and through a collaborative group of independent veterinary practices to their clients. Farmers were asked about (i) the incidence of presumed HypoMgT (PHT); (ii) their strategies to treat or prevent HypoMgT; (iii) mineral tests on animals, forage and soil, and (iv) farm enterprise type. A total of 285 responses were received from 82 cattle, 157 mixed cattle and sheep, and 46 sheep farmers, of whom 39% reported HypoMgT in their livestock, affecting 1–30 animals. Treatment and/or prevention against HypoMgT was reported by 96% respondents with PHT and 79% of those without. Mineral tests on animal, forage, and soil was conducted by 24%, 53%, and 66% of the respondents, respectively, regardless of PHT. There was a highly significant association between the use of interventions to tackle HypoMgT and the incidence of PHT (p < 0.01). The top three treatment/prevention strategies used were reported as being free access supplementation (149), in feed supplementation (59) and direct to animal treatments (drenches, boluses and injections) (45) although these did vary by farm type. Although some (9) reported using Mg-lime, no other pasture management interventions were reported (e.g., Mg-fertilisation or sward composition). Generally, the results indicate that UK farmers are aware of the risks of HypoMgT. A more integrated soil-forage-animal assessment may improve the effectiveness of tackling HypoMgT and help highlight the root causes of the problem

Development of Trust in an Online Breast Cancer Forum: A Qualitative Study

Background: Online health forums provide peer support for a range of medical conditions, including life-threatening and terminal illnesses. Trust is an important component of peer-to-peer support, although relatively little is known about how trust forms within online health forums. Objective: The aim of this paper is to examine how trust develops and influences sharing among users of an online breast cancer forum. Methods: An interpretive qualitative approach was adopted. Data were collected from forum posts from 135 threads on nine boards on the UK charity, Breast Cancer Care (BCC). Semi-structured interviews were conducted with 14 BCC forum users. Both datasets were analysed thematically using Braun and Clarke’s [2006] approach and combined to triangulate analysis. Results: Trust operates in three dimensions, structural, relational and temporal, which intersect with each other and do not operate in isolation. The structural dimension relates to how the affordances and formal rules of the site affected trust. The relational dimension refers to how trust was necessarily experienced in interactions with other forum users: it emerged within relationships and was a social phenomenon. The temporal dimension relates to how trust changed over time and was influenced by the length of time users spent on the forum. Conclusions: Trust is a process that changes over time, and which is influenced by structural features of the forum and informal but collectively understood relational interactions among forum users. The study provides a better understanding of how the intersecting structural, relational and temporal aspects that support the development of trust facilitate sharing in online environments. These findings will help organisations developing online health forums
