"Children with good memories tell better porkies"
Is the title of a recent BBC news report following research conducted by Dr Elena Hoicka at the University of Sheffield. Six and seven year old children were tested for verbal memory (measured by the number of words they could remember) and whether they would cheat on a game. Of those who cheated and then lied about it, the better liars were shown to have better verbal memory.
The research is reported in the Journal of Experimental Child Psychology and suggests that children who are better at remembering words are also better at lying which maybe the result of superior memory skills.
