Abstract
Background
Neuroplasticity is a phenomenon exhibited by our nervous system as an indicator of overall development and in response to training, injury/loss of particular function, treatment/drugs and as a result of stimulation from the surrounding environment.
Objective
The aim of the current study was to assess the auditory working memory capacities in Bharatanatyam dancers.
Method
The participants comprised fifty-four females with normal hearing sensitivity who belonged to two groups. Group-I consisted of 27 individuals who underwent formal training in Bharatanatyam for a minimum period of three years. Group-II consisted of the age-matched control group, consisting of 27 individuals who were non-dancers. The auditory working memory tasks included arranging the English digits presented binaurally in forward, backward, ascending, and descending spans. The maximum values (for the length of sequence arranged), midpoint values (average score), and response time for each task were noted down and compared among groups.
Results
The scores were compared using the Mann-Whitney U test, which revealed enhanced working memory exhibited by dancers for maximum values and midpoint scores for all three tasks except ascending span. It was also noted that the dancers exhibited a shorter response time compared to non-dancers for all the tasks except ascending span.
Conclusion
The current study highlights an enhanced auditory working memory capacity in Bharatanatyam dancers, which could be perceived as evidence of neuroplastic changes induced in the auditory and motor cortex as a consequence of extensive stimulation for auditory processing abilities and motor planning resulting from long-term dance training and regular practice.
期刊介绍：
Journal of Otology is an open access, peer-reviewed journal that publishes research findings from disciplines related to both clinical and basic science aspects of auditory and vestibular system and diseases of the ear. This journal welcomes submissions describing original experimental research that may improve our understanding of the mechanisms underlying problems of basic or clinical significance and treatment of patients with disorders of the auditory and vestibular systems. In addition to original papers the journal also offers invited review articles on current topics written by leading experts in the field. The journal is of primary importance for all scientists and practitioners interested in audiology, otology and neurotology, auditory neurosciences and related disciplines. Journal of Otology welcomes contributions from scholars in all countries and regions across the world.
