Independent and Dependent Variables Assignment Part 1: Identifying independent (IV) and dependent variables (DV) (10 points) Remember that an independent variable is manipulated, while a dependent variable is measured and may change as a result of exposure to the independent variable. A. Jury decisions are influenced by the attractiveness of the defendant. IV: DV: B. A drug company is advertising a new drug that helps people recover from jet lag faster. You are skeptical so you conduct an experiment to test their claim. In your experiment, 100 people are flown from San Francisco to Tokyo. During the flight, half the subjects are given the drug company’s new drug. The other half of the subjects are given a placebo (i.e., sugar pill) during the flight. Six hours after they land, all subjects are asked to rate how sleepy and disoriented they feel. IV: DV: Part 2: Operationally Defining Variables (10 points) Remember that the variables that we make hypotheses about are often abstract constructs. Designing research to examine the relationships between variables involves the process of operationally defining those variables in terms of how they are manipulated or measured. Consider the each of the following research descriptions, identify the variables and briefly describe how they are operationally defined. C. The nonconscious mimicry of the behaviors of interacting partners is referred to as the chameleon effect. Chartrand and Bargh (1999) performed a study to examine how mimicry within an interaction influenced the quality of the interaction and liking between partners. They had pairs of participants describe what they saw in photographs. One of the participants in each pair was a confederate (working with the researchers). Half of the confederates were instructed to mirror the behaviors of their partner, while the other half engaged in neutral mannerisms. Following the picture description interaction, participants completed questionnaires asking them to report how much they liked their partner (the confederate) and how smoothly the interaction had gone. The results showed that participants rated the interaction smoother and reported liking their partners more in the mimic condition than in the neutral condition. IV and definition:
