Abstract
AbstractWorking memory forms an important component of the command centre of brain. Incoming information from all sensory modalities lasting from few seconds to several hours requires working memory for immediate storage before those information gets stored as long-term memory. Loading working memory with many information at one time can result in corrupted storage in long term memory. This could lead to less efficient recollection of information. This study aimed to investigate the efficiency of performance while loading the working memory with both primary and secondary task at the same time. Participants performed Backward Wechsler Digit Span test for digits from 3 to 7 as primary task in with-music and no-music condition. Behavioural parameters namely typing duration and accuracy, and electroencephalography (EEG) parameters namely theta, beta and alpha bands was collected for three stages: encode, maintenance and recall. Results revealed decrease in accuracy as size of digit sequence increased in the presence of music. Spectral power of theta band increased during with-music condition in comparison to no-music condition indicating strain on working memory due to music. The study results revealed that listening to favourite music during task, loads the working memory and hinders the task performance.KeywordsWorking memoryMusicElectroencephalographyBackward digit span memory test
