Document Summary
Everything starts with a question, research in psychology starts with curiosity. Daily experiences, recent events, interesting topic, observations, lectures, other studies. While asking questions, scientists formulate their questions as testable statements or hypotheses. Hypotheses are predictions, tentative statements about the relationship between two or more variables. Variables are any measurable conditions, events, characteristics, or behaviours that are controlled or observed in a study. Theory is a set of interrelated ideas formed from observations. Psychologists construct a theory, system of interrelated ideas to explain a set of observations. Hyp:children that observe or watch aggressive adult models would reproduce aggressive acts. Here, watching aggressive adults" and aggressive acts" are the variables. Bandura can control exposure to aggressive models and he can observe aggressive act of children. Experimental: have control over a variable and observe the reaction of the other. The investigator manipulates a variable under carefully controlled conditions and observe an changes in the second variable.
