Unconscious plagiarism occurs when people try to generate new ideas or when they try to recall their own ideas from among a set generated by a group. In this study, the factors that independently influence these two forms of plagiarism error were examined. Participants initially generated solutions to real-world problems in 2 domains of knowledge in collaboration with a confederate presented as an expert in 1 domain. Subsequently, the participant generated improvements to half of the ideas from…

Understanding Unconscious Plagiarism: The Effects of Idea Elaboration and Perceived Idea Quality on Later Recall and Recognition of Ideas
Previous research has shown that idea improvement and perceived idea quality have differential effects on recall-own and generate-new plagiarism. Participants completed a generative task in pairs and
Unconscious Plagiarism in Recall: Attribution to the Self, but not for Self-Relevant Reasons
Previous research has shown that if people improve other’s ideas, they subsequently unconsciously plagiarise them at a dramatically higher rate than if they imagine them, or simply hear them again.
Social influences on unconscious plagiarism and anti-plagiarism
TLDR
Social influences on unconscious plagiarism are apparent, but are influenced by the salience of the alternate source at retrieval.
Accountability Reduces Unconscious Plagiarism
Summary: We investigated how holding participants accountable for their responses affected unconscious plagiarism when solving a Boggle puzzle task (finding words in a 44 letter matrix). Both
Simulating performance in unconscious plagiarism
TLDR
It is shown that guessing alone cannot account for the pattern of data participants show at test, which suggests that judgements of items’ memory strength alone cannot explain performance in the unconscious plagiarism paradigm.
No evidence of age-related increases in unconscious plagiarism during free recall
TLDR
Older adults were more likely than younger adults to intrude with entirely novel items not previously generated by anyone, which stands in opposition to the single previous demonstration of age-related increases in plagiarism during recall.
Simulation-Based Mentalizing Generates a “proxy” Self-Reference Effect in Memory
TLDR
It is suggested that self-reference by proxy enhances memory for non-self-relevant material, and the theoretical implications for functional interpretation of the SRE are considered.
Mechanisms leading to misattribution errors and cooperative knowledge acquisition
This study sought to clarify the process of knowledge acquisition by examining why people tend to misattribute others' activities as their own after having interacted with them. In Study 1, an

Why do I always have the best ideas? The role of idea quality in unconscious plagiarism
TLDR
Data indicate that different source-judgement processes underlie the two forms of plagiarism, neither of which can be reduced simply to memory strength.
When elaboration leads to appropriation: Unconscious plagiarism in a creative task
TLDR
Brown and Murphy's (1989) three-stage paradigm was used to assess the effects of participant elaboration on rates of unconscious plagiarism in two experiments using a creative task, finding that the probability of a person plagiarising another's ideas is linked to the particular nature of the elaboration carried out on that idea, rather than its familiarity.
The effects of repeated idea elaboration on unconscious plagiarism
TLDR
The effects of repeating the elaboration phase during the retention interval is explored and it is shown that repeating the improvement phase increased plagiarism to dramatically high levels in the recall task.
Whose idea was that? Source monitoring for idea ownership following elaboration
TLDR
The probability of plagiarising another's idea appears linked to the generative nature of the idea processing performed, and the effects of elaboration on rates of UP when a source-monitoring test replaced the recall-own test is explored.
Elaboration Inflation: How Your Ideas Become Mine
Unconscious plagiarism occurs when individuals claim previously experienced ideas as their own. Using an adaptation of Brown and Murphy's (1989) three-stage paradigm, participant elaboration was
The credibility of a source influences the rate of unconscious plagiarism.
TLDR
Three experiments were conducted to investigate the relationship between the credibility of information and later unconscious plagiarism of that information, and the results are discussed in terms of the explicit factors that affect the incidence ofconscious plagiarism.
Monitoring source in an unconscious plagiarism paradigm
TLDR
Recall-own plagiarisms increased when self- and other-generated solutions were difficult to distinguish and decreased when the two sources were easier to distinguish, and no effects were associated with the generative tasks.

TLDR
In three experiments, cryptomnesia (unconscious plagiarism) and source memory are investigated using a word-search puzzle task and a unitary relative strength model is used to explain both source and occurrence (item) forgetting.
Contexts of Cryptomnesia: May the Source Be with You
Cryptomnesia represents an intriguing type of mental illusion in which people mistakenly believe that they have produced a new idea when in fact they have simply unwittingly retrieved an old,
