One must be concerned of two particular types of issues regarding memory. That is the validity and the reliability. To deal with reliability one must also look to the effect of possible leading and suggestive questioning. Children are generally known to be cooperative conversationalists. This means that when children are talking to doctors, a psychologist, parents, polices officers, they tend to trust these adults as reliable sources of information in what is otherwise a very complex world.
Children are very good at attuning themselves into what the adult is looking for.
Children cooperate by figuring out what the adult is looking for and then giving the adult answers consistent with the questions which are being posed to the children. This is an example of children operating as cooperative conversationalists. They filter out the information which doesn't support their own theories. This was done in the McMartin preschool case. The biased interviews were contaminated by leading suggestive and coercive questions.
