#1
Daniel Voyer, Petra Jansen
The present study aimed to provide a summary of findings relevant to the influence of motor expertise on performance in spatial tasks and to examine potential moderators of this effect. Studies of relevance were those in which individuals involved in activities presumed to require motor expertise were compared to non-experts in such activities. A final set of 62 effect sizes from 33 samples was included in a multilevel meta-analysis. The results showed an overall advantage in favor of motor experts in spatial tasks (d=0...

Calvin Lam, Yanlei Li, Tim Landgraf, James Nieh
The function of the honey bee tremble dance and how it attracts signal receivers is poorly understood. We tested the hypothesis that tremble followers and waggle followers exhibit the same dance following behavior. If correct, this would unify our understanding of dance following, provide insight into dance information transfer, and offer a way to identify the signal receivers of tremble dance information. Followers showed similar initial attraction to and tracking of dancers. However, waggle dancers were faster than tremble dancers, and follower forward, sideways, and angular velocities were generally similar to the velocities of their respective dancers...

The National Institutes of Health Stroke Scale (NIHSS) is commonly used in Comprehensive Stroke Centers, but it has not been easily implemented in smaller centers. The aim of this study was to assess whether nurse providers who were naive to stroke assessment scales could obtain accurate stroke severity scores using our previously validated NIH Stroke Scale in Plain English (NIHSS-PE) with minimal or no training. METHODS: We randomly assigned 122 nursing students who were naive to stroke assessment scales to 1 of 4 groups: trained on the NIHSS, untrained on the NIHSS, trained on the NIHSS-PE, or untrained on the NIHSS-PE...

This study evaluated an intervention package that used public posting and feedback to enhance dance movements for adolescent dancers on a competition team. Four dancers each performing two or three dance movements (a turn, kick, and/or leap) had their scores posted on a bulletin board at their studio. Dance movements were scored as a percentage correct by using a 14- to 16-step task analysis checklist. Intervention was evaluated in a multiple baseline across behavior design. The students received graphical feedback on their performance from the previous weeks and saw the scoring sheet that reviewed the incorrect and correct aspects of their performance...

From animal research, it is known that combining physical activity with sensory enrichment has stronger and longer-lasting effects on the brain than either treatment alone. For humans dancing has been suggested to be analogous to such combined training. Here we assessed whether a newly designed dance training program that stresses the constant learning of new movement patterns is superior in terms of neuroplasticity to conventional fitness activities with repetitive exercises and whether extending the training duration has additional benefits...

BACKGROUND: Postural balance (PB) is an important component skill for professional dancers. However, the effects of different types of postures and different underfoot surfaces on PB have not been adequately addressed. PURPOSE: The main aim of the present study was to investigate the effect of different conditions of footwear, surfaces, and standing positions on static and dynamic PB ability of young ballet dancers. METHOD: Thirty-six male and female young professional ballet dancers (aged 14-19) completed static and dynamic balance testing, measured by head and lumbar accelerometers, while standing on one leg in the turn-out position, under six different conditions: 1...

Exotic dancers have received little research attention despite evidence of high-risk behaviours within exotic dance clubs (EDCs). We developed and assessed the reliability and validity of a risk environment score, examining differences between dancers (n = 107) and other staff (n = 172). In the summer of 2013, anonymous surveys were administered via A-CASI in EDCs (N = 26) in Baltimore among exotic dancers and staff. Surveys consisted of a brief demographic section followed by 65 statements. The overall domain had an alpha = 0...

Postural control is not a fully automatic process, but requires a certain level of attention, particularly as the difficulty of the postural task increases. This study aimed at testing whether experienced contemporary dancers, because of their specialized training involving the control of posture/balance, would present with a dual-task performance suggesting lesser attentional demands associated with dynamic postural control compared with non-dancers. Twenty dancers and 16 non-dancers performed a dynamic postural tracking task in both antero-posterior and side-to-side directions, while standing on a force platform...

The ability to know where our own body and body parts are in space is often taken for granted, yet it is of fundamental importance for the majority of our everyday activities, let alone high performance activities such as dancing. This review focuses on the concept of self-localization, the monitoring of the space surrounding one's body, and the disruptions that occur in the presence of pain. A conceptual model is presented of the cortical body matrix with which to consider self-localization; also provided are its historical context, underlying assumptions, and current limitations...

BACKGROUND: The physical demands placed on dancers put them at significant risk for injury, with rates similar to ones sustained by athletes in sports at the same level of performance. Muscle strength has been suggested to play a preventative role against injury in dancers. OBJECTIVE: To systematically search and examine the available evidence on the protective role of muscle strength in dance injuries. METHODS: Five electronic databases and two dance-specific science publications were screened up to September 2015...

Do we perceive a group of dancers moving in synchrony differently from a group of drones flying in-sync? The brain has dedicated networks for perception of coherent motion and interacting human bodies. However, it is unclear to what extent the underlying neural mechanisms overlap. Here we delineate these mechanisms by independently manipulating the degree of motion synchrony and the humanoid quality of multiple point-light displays (PLDs). Four PLDs moving within a group were changing contrast in cycles of fixed frequencies, which permits the identification of the neural processes that are tagged by these frequencies...

BACKGROUND: EEG studies investigating the neural networks that facilitate action observation (AO) and kinaesthetic motor imagery (KMI) have shown reduced, or desynchronized, power in the alpha (8-12 Hz) and beta (13-30 Hz) frequency bands relative to rest, reflecting efficient activation of task-relevant areas. Functional modulation of these networks through expertise in dance has been established using fMRI, with greater activation among experts during AO. While there is evidence for experience-dependent plasticity of alpha power during AO of dance, the influence of familiarity on beta power during AO, and alpha and beta activity during KMI, remain unclear...

In this study, we tested the hypotheses that, relative to the maximum capacities, ballroom dancing is more intensive for females than males, and that the hold technique (female vs. male) regulates dancing intensity. Ten dance couples were tested in a maximal treadmill test, competition simulation, and stationary dance hold position. Peak heart rate and relative oxygen consumption were measured during the tests, except that oxygen consumption was not measured during competition simulation. Regardless of gender, heart rate increased similarly in the treadmill test and in the competition simulation...
