Music Modulates Cognitive Flexibility? An Investigation of the Benefits of Musical Training on Markers of Cognitive Flexibility

Abstract

Cognitive flexibility enables the rapid change in goals humans want to attain in everyday life as well as in professional contexts, e.g., as musicians. In the laboratory, cognitive flexibility is usually assessed using the task-switching paradigm. In this paradigm participants are given at least two classification tasks and are asked to switch between them based on valid cues or memorized task sequences. The mechanisms enabling cognitive flexibility are investigated through two empirical markers, namely switch costs and n-2 repetition costs. In this study, we assessed both effects in a pre-instructed task-sequence paradigm. Our aim was to assess the transfer of musical training to non-musical stimuli and tasks. To this end, we collected the data of 49 participants that differed in musical training assessed using the Goldsmiths Musical Sophistication Index. We found switch costs that were not significantly influenced by the degree of musical training. N-2 repetition costs were small for all levels of musical training and not significant. Musical training did not influence performance to a remarkable degree and did not affect markers of mechanisms underlying cognitive flexibility, adding to the discrepancies of findings on the impact of musical training in non-music-specific tasks.

The relationship between music training and cognitive flexibility: an ERP study

“…Cognitive flexibility is a key concept within executive function, which is defined as the ability to transform in different settings or psychological preconceptions (Chen et al, 2017 ), and it helps individuals adjust their thoughts and goals more flexibly in their daily and professional lives according to changing needs (Gade and Schlemmer, 2021 ). Musicians have stronger task-switching abilities and consume less global switch costs than non-musicians, suggesting that musicians have enhanced global processing capabilities and can switch between switching and non-switching components more efficiently (Moradzadeh et al, 2015 ).…”

Effectiveness of Eye Movement Desensitization and Reprocessing Therapy in Response Inhibition and Cognitive Flexibility of Veterans with Posttraumatic Stress Disorder

“…The main element of cognitive flexibility is the ability to change cognitive sets to adapt to variable stimuli in the environment (14). Denoting distress tolerance, flexibility is defined as a person's ability to cope with negative emotions (15). Individuals with low levels of distress tolerance presume emotion as an intolerable entity and deny its existence.…”
