Flashcards in Research Deck (36)
Describe the SCIENTIST-PRACTITIONER model
Scientific research is used to inform practice and practice is investigated through scientific research
Describe the 5 the non-scientific ways of knowing.
Tenacity - superstition or habit
Intuition - not based on reasoning or inference. Eg. a gut feeling
Authority - perceived experts or respected sources
Rationalism - reasoning and inference based on what you think you already know plus new information
Experience/Empiricism - learning by doing/seeing/feeling, observing phenomena. This is susceptible to the availability heuristic
What is the AVAILABILITY HEURISTIC?
Relying on information that is easy to recall because it is readily available or somehow unusual and therefore memorable
What are the 8 aspects of GOOD scientific research?
- Informed by the work of others
- Generaliseable to other settings
- Based on logical rationale and theory
- generates NEW questions
- is an apolitical activity (as much as it can be)
What is FALSIFICATION?
The act of showing a hypothesis to be false. A good hypothesis/research question should be able to be shown to be false (falsified).
What are 4 goals of the scientific method?
What are the two approaches to research in psychology?
Basic and Applied research
What are 4 aspects of BASIC RESEARCH?
Attempts to answer fundamental questions on how the world works. Eg. Cognition, emotion, motivation, personality etc
Arises from curiosity, there isn’t a specific application in mind
High levels of control
Emphasis on supporting or refuting theories
What are 2 aspects of APPLIED RESEARCH?
Address practical problems and potential solutions
Less control as they take place on the real world
What does a capital N stand for?
Total participants in a study
What does a lowercase, italicised ‘n’ stand for?
Total participants in group
List the 4 types of NON EXPERIMENTAL research design
What is DESCRIPTIVE research?
It describes or aims to get an accurate picture of a particular situation without interventions (“as it stands”)
It serves as a base for future studies
What is HISTORICAL research?
Utilities pervious research and data already collected to investigate a phenomena
What is QUALITATIVE RESEARCH?
Looks at non-quantitative results.
Is interested in behaviour in larger contexts such as social, cultural and political
What is CORRELATIONAL RESEARCH?
Investigated relationships between selected variables
Helps to predict another event
What is a NEGATIVE CORRELATION?
When one variable increases the other decreases.
The closer the correlation co-efficient (r) is to -1 the stronger the negative correlation
What is a POSITIVE CORRELATION?
As one variable increases so does the other.
The closer the correlation co-efficient (r) is to 1, the stronger the positive correlation
What are the 3 features of a TRUE EXPERIMENT?
Participants are able to be RANDOMLY assigned to groups
The independent variable (or ‘treatment’) is controlled by the researcher
There is control over potential causes of behaviour (extraneous variables?)
What are the 2 features of a QUASI EXPERIMENT?
Participants cannot be randomly assigned to groups. The groups are naturally occurring.
They are useful when you cannot control the variable
What is an INDEPENDENT VARIABLE?
What is a DEPENDENT VARIABLE?
What is a CONTROLLED VARIABLE?
What is an EXTRANEOUS VARIABLE?
What is a MODERATOR VARIABLE?
What is a MEDIATOR VARIABLE?
Describe a BETWEEN SUBJECTS research design
aka Independent Samples
Each group is subject to only one level of each independent variable
Eg. placebo VS treatment
Describe a WITHIN SUBJECTS research design
aka Repeated Measures
All participants are subjected to both levels of the independent variable (eg. placebo & treatment)
This occurs over time
What is a NULL HYPOTHESIS and why is it important?
That there is no relationship between the variables you are investigating
