Summary

This review paper examines the contribution of Marcello Cesa-Bianchi’s school to the understanding of how mental imagery facilitates creative thinking and problem-solving across various states of vigilance, including wakefulness, resting states, mind wandering, sleep onset, and REM sleep. The research is motivated by the observation that innovative solutions to artistic, scientific, or everyday problems require the flexible recombination of prior knowledge. Cesa-Bianchi’s work challenged traditional views that undervalued visual thought, proposing instead that intentionally generated and transformed mental images serve as a crucial mechanism for insight and creative restructuring. The paper synthesizes experimental evidence gathered over decades, primarily from Italian research groups in Milan, Bologna, and Rome. The authors analyze studies investigating the functional role of visual representations in cognitive processes. Early correlational studies examined the relationship between specific imaginative abilities—such as holistic mental transformation versus sequential manipulation—and creative problem-solving skills. Later experimental designs focused on the neurophysiological and cognitive differences between vigilance states, utilizing tasks such as anagram resolution, hidden rule discovery (e.g., the Number Reduction Task), and semantic association tests. These studies compared performance after periods of wakefulness, NREM sleep, and REM sleep, often measuring cognitive flexibility and insight rates during sleep inertia or upon waking. The findings indicate a strong link between the ability to manipulate mental images holistically and creative thinking. Visual representations allow for simultaneous processing of multiple dimensions, enabling rapid restructuring of problem representations and the discovery of novel relationships between disparate information. Regarding vigilance states, the research demonstrates that insight can occur during sleep, sleep onset, resting, and mind wandering. These states foster the spreading activation of episodic and semantic knowledge within associative networks. Specifically, REM sleep acts as an incubation period that enhances solution rates for complex tasks, such as discovering hidden mathematical rules and solving anagrams, by facilitating the decomposition and recombination of concepts. In contrast, NREM sleep tends to facilitate the extraction of common semantic traits and the integration of recent information with remote or abstract knowledge. The significance of this work lies in its validation of sleep and relaxed vigilance states as active periods of cognitive processing rather than passive intervals. The results support the notion that incubation periods, whether through sleep or mind wandering, are beneficial for solving problems regardless of their domain. By demonstrating that visual mental imagery and specific sleep stages facilitate the breaking of mental sets and the formation of unexpected associations, the paper underscores the importance of non-active states in the creative process. This contributes to a broader understanding of creativity as a dynamic interaction between conscious manipulation of images and unconscious associative processing during altered states of consciousness.
