Internal Validity and Maturation
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?
