The document summarizes a study that tested how the order of difficulty of sections in a general knowledge quiz impacts participant compliance and mood. Twenty students took a four section quiz, with half receiving the easiest section first and half receiving the most difficult section first. The researchers found that more participants who received the easier sections first completed the entire quiz, supporting their hypothesis about compliance. However, their hypothesis about mood was only partially supported, as most participants who received easier sections first reported improved mood but results were mixed for those who started with harder sections. The researchers noted limitations and factors like challenge preference that could influence the results.
