Internal Validity and Maturation

Hello! I added the internal validity threat: participant maturation to this page. Let me know if there is anything that seems off about the edit. I thought it was important to add it, however, since there is no controlled setting for when participants actually take the questionnaire...unlike certain studies where participants are in a room or what not without distractions while completing the questionnaire.

Here is a tiny section from the book - internet research methods, that covered basically what you said about maturation. Checkout P.42-45, questionnaire , see if you can find more information to add onto your part. http://books.google.ca/books?hl=zh-TW&id=r5kz94nV_pIC&q=when+materials+are+administered+via+a+computer+terminal+rather+than+in+person%2C+the+researcher+is+less+able+to+judge+the+extent+to+which+the+responses+are+sincere+and+genuine%2C+the+conditions+under+which+the+questionnaire+was+answered+and+the+state+of+the+participants+at+the+time+of+participation+%28for+example%2C+intoxicated%2C+distracted%2C+and+so+on%29+-+See+more+at%3A+http%3A%2F%2Fwww.restore.ac.uk%2Form%2Fquestionnaires%2Fquesprint2.htm%23sthash.FYBtoHtQ.dpuf#v=onepage&q=distracted&f=false

Hey Chelsea! I like the maturation paragraph. I edited some parts of the paragraph, so it flows better with the rest of the page. However, I wasn't sure what you meant by fatigue in the sentence of "causing temporary factors, such as fatigue to affect the way participants answered questions". Just wondering what kind of fatigue are you referring to?
