Psychology : please provide answer. In the following description of a hypothetical experiment identify the independent variable, the levels of the independent variable, the dependent variable, and how both the IV and the DV are operationally defined. 1. Researchers are interested in whether amount of alcohol affects anxiety level following short-term social isolation. A researcher randomly assigns participants to one of three levels of alcohol; one drink containing one ounce of alcohol, two drinks containing ounce of alcohol each, or a drink that contains no alcohol (placebo). The participants then play a computer game with two participants (said to be at other locations) who are displayed on the screen as avatars. After 5 minutes of playing, the other avatars stop throwing the ball to the participant; rather they simply toss the ball back and forth. After an additional 10 minutes of playing, the game stops and the participant is asked to rate their level of anxiety on the State-Trait Anxiety Inventory (STAI).
