Add to development section looks good. I am curious as to what the reasoning behind why they didn't have preference when viewing peoples faces of Asian decent though/ is that necessary to include? May be helpful to include more about the ethnicity of these children in the experiment that you found.
"studies based on neuropsychology, behavior, electrophysiology, and neuro-imaging have supported the notion of a specialized mechanism for perceiving faces" for this quote, can you be more specific? what exactly did these studies look at? Seems like a pretty general and vague sentence.
"However, none of these results were found when perceiving a dog face" these seems as though it were taken out of context....What does it mean that we can percieve human faces in this study but not dog faces? may need to add a sentence for clarity.
In your second to last bullet, you simply say "one study" and "another study." Is there a way you can be more specific as to which study you are referring to here? I do not know if Wikipedia would prefer this or the vagueness though.
