The cognitive orchestra

Introduction

Music has considerably always been a universal way of communicating. Every day, we are introduced to new genres and concepts despite the differences in language or musical techniques. As a result, psychology has increasingly researched music and its effects on human cognition.

Music as a means of therapy

The common way most people use music is to regulate their emotions. When we are feeling down, we are more than likely to choose a melancholic playlist over an upbeat one. It has been found that music aids in uplifting mood and reducing anxiety. Juslin and Sloboda (2010) demonstrated that people often choose to listen to music that links to how they are feeling in the moment or even how they desire to feel.

With music being deemed a powerful emotional mechanism, music therapy has seen its benefits as a tool for regulating emotions. Thoma et al. (2013) support the idea of music being used for treating conditions like depression and PTSD, with their findings indicating that music listening impacts the psychobiological stress system. Listening to music prior to a stressful event predominantly affected the autonomic nervous system by recovering the nerves much faster, although the effects on the physiological stress and the endocrine (stress hormones) were not as noticeable.

However, just as all forms of therapy are not generalisable to everyone, music therapy is not always an appropriate solution. The over-reliance on music to regulate feelings can lead to emotional avoidance and not addressing the initial cause of low mood. This leaves no room for solving the issues at hand. In the context of neurological rehabilitation, it was suggested that further controlled studies are needed to establish the efficacy of music in neurological recovery, and music-based interventions are emerging as promising rehabilitation strategies.

Mental clarity or spiritual melodies?

The benefits music can hold for our cognitive abilities are endless. Musical training in childhood, studied by Forgeard et al. (2008), is positively correlated with enhanced fine motor skills and non-verbal reasoning. Children were predicted to have much better cognitive flexibility and strengthened memory, outperforming the experimental control group. Another advantage music holds for cognitive abilities is making tasks easier to work with. Lesiuk (2005) conducted a study into the influence of music on mood and work performance. He introduced a ‘no music’ rule for workers in a software company, where they were prohibited from listening to music whilst working. The results demonstrated a predictable decrease in quality of work once music was abandoned, which workers were not habitually familiar with. Performance in quality of work remained poor in week 4, but managed to improve again when music was involved again during week 5. Although, it is important to note that music as a means of concentrating is not always beneficial. Lyrical songs can potentially act as a distractor when completing tasks that require verbal or visual memory, hindering our cognitive ability.

Zulkurnaini et al. (2012) studied Lesiuk (2005) hypothesis, exposing participants to classical music and a verse from the Quran. By observing EEG signals, they found that listening to the Quran resulted in a more relaxed state compared to classical music. They also found that listening to the Quran increased the alpha band in the brain, which is associated with relaxation.

Conclusion

It is clear music is more than just a background track while completing daily errands. The influence it has on emotional well-being, memory and mood is vital to acknowledge. With evidence of positive correlations between cognitive productivity and listening to music, and neurological research of in-depth brain studies, the effects of music are much more prevalent to us. Future research should aim to look into the long-term effects on cognitive functioning, more specifically within clinical settings like neurorehabilitation.
