Research Methods Paper 2 Flashcards
What is the acronym used to remember the scientific principles of Pyschology?
THE PROF
What does each letter stand for in THE PROF?
Theory construction, hypothesis testing, empiricism, paradigms, replicability, objectivity, falsifiability.
What are the two types of reasoning in theory construction?
Inductive and deductive
What is inductive reasoning?
Making a specific observation, recognizing a pattern and drawing a conclusion/theory based on the specific research done.
What is deductive reasoning?
Starting with an existing theory, create a hypothesis or theory based off that, research, experiment and collect data to confirm/deny that theory.
What is empiricism?
Factual knowledge can only come from our own personal experiences. Rigorous scientific and empirical testing must be done to prove a theory.
What is the process of hypothesis testing?
1)State the hypothesis
2)Conduct experiment
3)Choose test statistics
4)Make a decision and analyze statistics
5)Draw conclusion about population
What is an aim?
A general statement of the purpose of the study/a general statement about what the researcher intends to study
What is a hypothesis?
A prediction of what the researchers will find in the research.
What is the null hypothesis?
A prediction with no significant effect or relationship between the variables.
What is a directional hypothesis?
It is one-tailed so previous research has been done before so it can be specific on the relationship between variables.
What is a non-directional hypothesis?
It is two-tailed so no previous or consistent research has been done before so the relationship between variables is more general.
What is an independent variable?
The variable being changed. (the cause)
What is a dependent variable?
The variable being measured. (the effect)
What does operationalise mean?
To clearly define the variables’ abstract terms in measurable observations.
What are covariables?
The two dependent variables in a correlation being measured.
How do you operationalize a DV?
Be specific in how to measure the variable.
How do you operationalize an IV?
State the levels/conditions.
What is a paradigms?
A set of shared assumptions and agreed methods within a shared discipline.
What is a paradigm shift?
A significant change in the dominant theory within a subject discipline due to a scientific evolution.
What is an example of a paradigm shift?
In the 1950s, a more scientific approach was brought to psychology.
What does replicability mean?
The extent to which scientific procedures and findings can be repeated by other researchers?
What makes a research replicable?
A simple standardized method, teaching your methods and a controlled environment like a lab.
Why is replicability important in pyschology?
It makes results more accurate and reliable, a more generalizable test means researchers can find out more about the specific study.
