24
Define External validity
The ability of researchers to generalize results to individuals beyond the study
25
Define Construct validity

26
Define Internal validity
No other variables explain the relationship, no confounds are present
27
What is parsimony and what is an example of the principle?
the simple solution (the one with the least assumptions) is often the best. - Example: Pavlov's dog salivated when he heard the bell because he knew it meant food another explanation could be complex unseen processes within the dog.

Where do we get our knowledge and beliefs from?
Authority figures, experience, intuition, and empiricism
29
What makes a theory good quality?

30
How is inductive reasoning used in the scientific method?
To formulate a theory, making a generalization about a population with some facts
31
How is deductive reasoning used in the scientific theory?
To test a hypothesis, using a proven generalization to ask a question
32
What is basic research?
Basic research is an attempt at further understanding of a subject while applied research is asking a question (finding ho well new treatments for depression is working)
33
What is applied research?
Developing ideas found in translational research and building upon topics into more complex research endeavors, such as evaluating the quality a new treatment has
33
What is translational research?
Taking the information from basic research and beginning the process of finding building ideas
34
What are imitations to the credibility of making conclusions based on experience?
The credibility can only be applicable in the areas the individual is experienced in, there is no comparison group resulting in confounds, and personal experience can result in bias..
35
How do you control the presence of confounds?
Accounting for them within an experiment
36
Why do we need comparison groups?
In order to prevent confounds, the researcher is able to ensure that the changed between groups is due to the independent variable and nothing else
37
Why should we not rely on our intuition alone?
Our brains love a shortcut "Good story bias," we are biased (present/present bias: it rains every ti
38
What is the availability heuristic/pop-up principle?

45
Why should we do experiments?
Provides internal validity, temporal precedence, as well as allowing us to control extraneous variables through holding confounds constant and random assignment

57
Define justice.
A principle of the Belmont Report, the participants equally benefit as much as the general population
58
What is the Belmont +2?
Beneficence, justice, respect for persons, plus integrity and fidelity and responsibility
58
What is "the 10"?
Resolving ethical issues, competence, human relations, privacy and confidentiality, advertising and public statements, record keeping and fees, education and training, research and publication, assessment, and therapy
59
What is the APA Standard 8?
This is specific to research, the IRB, deception, debriefing, research misconduct, and animal research
60
