Answer 1

1. Operational Definitions: visualizations of the brain before and after the beginning of the experiment, using magnetic resonance equipment.

2. Independent variable: frustration levels. Dependent variable: Situations of aggression. Operational Definitions: Observation of changes in behavior related to adverse moments.

3. Independent variable: contact comfort received as a child. Dependent variable: relationships between adults. Operational Definitions: Comparison between childhood and adult behavior

Step-by-step explanation:

Independent variable (IV): it is the element in the research that influences a result and acts on the dependent variable so that an easily measured and observable result can be perceived.

Dependent variable (DV): it is the element that is influenced by the IV and is observed from it, thus creating a measurable result. This variable does not occur naturally and needs to happen due to the influence of another element.

Operational Definitions: is the term used to describe what will be measured within the experiment and how this measurement will be carried out so that it is possible to reach a conclusion.
