Abstract
Despite increasing popularity, media attention, and commercial success of fidget spinners, scientific evidence on their effectiveness is scarce. The purpose of this study was to explore how fidget spinners affect fine motor performance and its neural correlates in the Prefrontal Cortex (PFC). Functional Near Infrared Spectroscopy (fNIRS) was used to examine the PFC activity while a group of healthy adult participants completed five different sub-tasks of the Purdue Pegboard Task (PPT). In this study, fidget spinners resulted in a significant decrease in ΔHbO compared to the controls during performance of the more cognitively demanding assembly subtask despite no differences in behavioral output. No other main effects for group existed in the other sub-tasks, although significant group by block interactions occurred in all four brain regions. This finding suggests that fidget spinners may reduce the cognitive load on LDLPFC during a cognitively challenging fine motor task.
