“…Prime examples include such phenomena as functional fixedness, which involves restricting the uses of objects to well-known functions (Maier, 1931), and mental set, which involves situationally induced obstacles to problem solving (Luchins, 1942). Furthermore, it has been found that providing (Dahl & Moreau, 2002;Jaarsveld & van Leeuwen, 2005;Jansson & Smith, 1991;Marsh, Bink, & Hicks, 1999;Marsh, Ward, & Landau, 1999;Ward, 1994) or retrieving (Ward, 1994) existing examples may inhibit generative creative processes and may lead to a higher proportion of property transfers from the examples into the subject's own work (e.g., Marsh, Landau, & Hicks, 1996), even when the subject is explicitly instructed to avoid such transfer (e.g., Smith, Ward, & Schumacher, 1993). Source monitoring of this property transfer is especially poor in generative tasks (e.g., Marsh, Landau, & Hicks, 1997), which originally led to the label unconscious plagiarism, or cryptomnesia (Brown & Murphy, 1989;Marsh & Bower, 1993;Marsh & Landau, 1995;.…”
