As the world has become more and more complex, the concern with creativity has increased (Runco, 2004). How can we improve our creative thinking abilities? Adams (1974) proposed that the process of consciously identifying conceptual blocks was essential for overcoming them and improving the ability to think creatively. A considerable number of studies have been conducted on factors that influence creativity. According to a review by Batey and Furnham (2006), much research has been directed to relationships between creativity, intelligence and personality. Moreover, studies have been conducted from diverse perspectives, such as motivation, affect, cognitive capacity, the social environment, culture and neurology (for reviews, see Hennessey & Amabile, 2010; Runco, 2004).
