In Stanley Schachter and Jerome Singer's classic experiment, participants were injected with epinephrine and either informed or not informed about the drug's effects. Participants were later asked to rate their own emotional states. Which alternative below correctly names and identifies a variable in this experiment?
independent variable—whether participants were informed about epinephrine's effects

- the emotional states people rates themselves DEPENDS ON whether they were told of the effects or not

Independent variable- Whether or not participants were informed about epinephrine's effects.

Explanation:

The question above shows an example of a scientific experiment. As you already know, a scientific experiment is composed of variables, these variables are called dependent and independent.

The dependent variable is one that needs to be influenced by another variable to establish an observable result. On the other hand, the independent variable is the one that influences the dependent variable and that its manipulation is directly related to the observable result.

In the above experiment, he observed whether information about the effects of adrenaline injected on patients influenced the assessment of the emotional behaviors they exhibited during the experiment.

With this we can conclude that the independent variable refers to whether the participants were informed about the effects of epinephrine

independent variable—whether participants were informed about epinephrine's effects.

Explanation: From the experiment above, we can conclude that there are two types of variables associated with the experiment. The independent and dependent variables.

The dependent variable (which in this case is the participants rating of their emotional state) usually conveys the output of an experiment based on the effect of the independent variable.

The independent variable (which in this case is whether participants were informed about epinephrine's effect) refers to the controlled input which influences the output of the dependent variable.
