I am seeking literature based in the discipline of psychology, that discusses the personality traits of individuals who plagiarize or commit other forms of academic misconduct.
I taught Psychology for many years and prior to that I taught physics. I found that psychologists were obsessed with the 'crime' of plaigerism whereas scientists in physics, chemistry and biology give students credit and dare I say praise for being able to accurately repeat facts such as a cat has four legs and fur and if you burn it's fur it will scream. Electronic plaigerism scanners pick up sentences such as this as plaigerism and so would some psychologists but it is necessary to learn facts and learning facts is a stage in being able to think critically. Students who don't attempt to think critically are often scared to question simply because they do not know the facts and don't want to look stupid. A second strategy that is very useful in learning a domain and which is often mistaken as plaigerism is the use of analogy e.g. The concepts of 'sport' and game are overextended when their condujuct is formed. The concepts of 'chair' and 'table' are overextended when their conduct is formed.
Returning to your question I'd widen my search for literature to all academic domains given the above and be aware that 'plaigerism' is sometimes not a crime.
Sorry I tried to edit my previous answer and it did not save.
'I just wanted to say look at the sample in the psychological studies for biases culture domain of study age all sorts of factors could influence their results.
I believe that Bev Macleod and Randy Genereux of Mount Royal University in Calgary have conducted research on personality and cheating behaviour. at University. An older example can be found with: Predicting the acceptability and likelihood of lying: The interaction of personality with type of lie. Personality and Individual Differences 45 (2008) 591–596.
