Elliot and Niesta (2008) tested the hypothesis that men would find a woman more attractive when she was surrounded by a red background than when she was surrounded by other colors.

Which of the following procedures can be used to help ensure standardization of conditions?

Which of the following refers to a measured variable used to determine whether the manipulation has unwittingly caused differences on other variables that might be systematically related to the independent variable?

The possibility of making a Type 2 error in an experiment would most likely be reduced by using which of the following procedures?

Which of the following refers to an artifact that occurs when participants' expectations about what effect an experimental manipulation is supposed to have influences the dependent measure independently of the actual effect of the manipulation?
