Document Summary
Studies with one independent variable are able to show a difference between conditions: ex. People drove more poorly while using cell phones (cell phone minus control) Experiments with two independent variables can show interactions. Interaction effect: effect of an additional independent variable on the original study whether the effect of the original independent variable (ex. Cell phone use) depends on the level of another independent variable (ex. Interaction of 2 independent variables = a difference in differences: ex. The difference between the cell phone and control conditions (cell phone minus control) might be different for older drivers than younger drivers. Behaviours, thoughts, motivations, and emotions involve the interactions between two or more influences: important research explores interactions among multiple independent variables. Probably depends on the food ice cream = cold, pancakes = hot. 2 independent variables: food you are judging (ice cream or pancake, temperature of food (cold or hot) Dependent variable: how much you like the food.
