Eliciting cryptomnesia: unconscious plagiarism in a puzzle task

Area of Science:

• Cognitive Psychology
• Memory Studies

Background:

• Cryptomnesia, or unconscious plagiarism, is a phenomenon where individuals unknowingly use previously encountered information as their own.
• Understanding the factors influencing cryptomnesia and source memory is crucial for cognitive psychology research.

Purpose of the Study:

• To investigate cryptomnesia and source memory using a novel word-search puzzle task.
• To compare cryptomnesia rates in this task with previous findings.
• To examine the effects of retention interval and encoding depth on cryptomnesia.

Main Methods:

• Three experiments were conducted using a word-search puzzle task where subjects alternated word generation with a "computer partner."
• Subjects attempted to recall previously generated items and locate new words.
• A modified recognition memory task was used to assess source confusions.

Main Results:

• Cryptomnesia rates were substantially higher in the word-search task compared to studies using category exemplar generation.
• Retention interval and degree of encoding reliably influenced the rates of cryptomnesia.
• Source confusions were analyzed to develop a model of memory forgetting.

Conclusions:

• The word-search task is a sensitive paradigm for eliciting cryptomnesia.
• Memory processes, including retention interval and encoding, play a significant role in unconscious plagiarism.
• A unitary relative strength model can explain both source and item forgetting in memory.
