The independent variable in this study is whether the participant received the injection of epinephrine or a neutral compound. This is the variable that the researchers manipulated in order to see how it impacted the participant's emotional response to the confederate. The other options listed are either not manipulated by the researchers (such as participant's mood or gender) or are not relevant to the study (such as hula-hooping).
