Dr. Corely was studying individuals' ability to use available resources to solve various puzzles as a means to test cognitive flexibility. Dr. Corely realized that after participants had been exposed to the third experimental condition they were starting to catch on to the study's purpose. This is an example of:

Faustino is examining the allergy effects of different brands of men's cologne. He has collected 40 people for each of the cologne conditions and has approximately 300 participants among the conditions. However, Faustino's research question can only truly be tested if he uses the same participants in all conditions, otherwise he will not have standardized the various allergy conditions and it will be difficult to draw conclusions regarding the colognes' likeliness to cause an allergic reaction. Faustino may want to consider re-designing his study to use a:

Recent statistics have claimed that autism spectrum disorder diagnoses have skyrocketed among youth. However, many researchers have pointed out that the recent shifted to the DSM-5 resulted in reclassifications of many individuals to the autism spectrum as Asperger's disorder is no longer an available diagnosis.

Dr. Pullman had an overwhelming number of freshmen sign up for his study once he offered extra credit. He was asking students to be hooked up to an EEG machine as well as to experience a low-voltage shock when they answered questions incorrectly. The participants had to return to the lab on three occasions in order to gain enough data to answer Dr. Pullman's hypotheses. After the first full round of participation, Dr. Pullman was told by the administration that he could not offer extra credit for participation in his experiment, so he had to remove the offer of extra credit. What should Dr. Pullman be concerned with?
