Deletion of Child Lying

Comment: I looked deep into this subject and article so bear with me. I found a complete build-up of an unsourced or under-sourced collection of |synthesis resulting in |original research. This is what is to love about the many branches (disciplines) of psychology covered on Wikipedia. This "study" (research/article) concerning an area of ''Child psychology'', a branch or specialty of "developmental psychology", is interesting but where are the sources to actually back up the subject
