• Dr. Hernandez predicts that the group of rats that receives “medication A” will see a greater reduction in anxiety symptoms compared to “medication B”. He administers the medications to the rats every day. Dr. Hernandez never directly handles or holds the rats, but he does know which rats receive which medication. . .Dr. Hernandez rates each rat’s freezing behavior on a 7-point scale and their exploration on a 7-point scale by watching them for 20 minutes. Given the design of the experiment there is a possibility that ______________ may impact the results.

• As part of an experiment, Feng is seated in front of a blank computer screen. On each trial, an object appears and the task is to name the object as rapidly as possible. The object is either presented alone or within a scene. For example, a chicken may be presented alone or in a barnyard. Feng is significantly faster at naming the object when it is presented in a scene. This result of faster reaction times is evidence for:

  Top-down processing in visual perception
• Katrina knows she is participating in a psychology experiment about math test anxiety. When she arrives at the lab to take the math test, the experimenter greets her and is very friendly.

She thinks that she must be in the low anxiety group and intentionally tries to perform better. This would most clearly be an example of
