  1. Unintended Plagiarism The experiment of Marsh et al. (1997): Research into implicit memory (see Claparède, 1911) people may access contents stored in memory without being able to remember these contents consciously. If so, it is possible that people may have access to an old idea without knowing that it is old, as shown by Brown and Murphy (1989). This unintended plagiarism has been called cryptomnesia. Marsh et al. examined the role of source monitoring (e.g., Johnson & Raye, 1981) for cryptomnesia. Contributor © POSbase 2003

  2. Unintended Plagiarism • Brainstorming sessions in groups of two to four participants. Their task was to generate ideas, how can traffic accidents be reduced. • After one week, the same participants had to generate new ideas. • One group of participants had to elaborate on the source of their ideas (source group), the other group had to generate ideas spontaneously (no source group). • A final recognition test examined whether participants remembered the old ideas and their source. • Participants of the source group should copy less old ideas than those in the no source group. However, both groups were expected to show the same recognition performance. © POSbase 2003

  4. Unintended Plagiarism The findings supported the predictions: If participants elaborated on the source, they copied less ideas than participants who generated ideas spontaneously. The authors concluded that those who monitored the source of ideas showed less unconscious influences on the generation of new ideas than those who did not think about it. © POSbase 2003

  5. Unintended Plagiarism • Unintended plagiarism is related to other phenomena, such as: • Illusions of familiarity (Jacoby & Whitehouse, 1989; Whittlesea, 1993) • Affective preference (Kunst-Wilson & Zajonc, 1980) • False fame (Jacoby et al., 1989) • False truth (Brown & Nix, 1996; Hasher et al., 1977) • Judgments of performance (Kelley & Jacoby, 1996) • Metacognitive judgments (Begg et al., 1989) • Judgments of time (Witherspoon & Allan, 1985) © POSbase 2003
