While little research has been conducted on the impact of sleep deprivation on divergent thinking, one study by J.A. Horne illustrated that even when motivation to perform well is maintained, sleep can still impact divergent thinking performance. In this study, twelve subjects were deprived of sleep for thirty-two hours, while a control group of twelve others maintained normal sleep routine.
A notable gap in research exists regarding the impact of sleep deprivation on divergent thinking processes, but J.A. Horne's study provides valuable insights into this area. In his investigation, twelve participants were subjected to prolonged wakefulness for thirty-two hours, while a control group of twelve others adhered to their regular sleep schedule.
