Exam 1: Ch. 1-5 Flashcards
What makes psychology a science?
Invention of computers led to cognition
Mental processes and behavior are intertwined
What defines science?
Knowledge in the form of testable predictions and explanations
What differentiates science from pseudoscience? Ex?
Lacks reliance on empiricism and skepticism
Ex: phrenology
Empiricism
Claims based on evidence/data
Skepticism
Not accepting a claim without evidence
Confirmation bias
Selectively accepting evidence that confirms a belief, or vice versa
What are the 4 goals of the scientific method?
- Description
- Prediction
- Explanation
- Application
SM: Description
Describes the events and relationships between variables
SM: Prediction
Make a prediction
SM: explanation
Why does it occur?
SM: Application
Apply knowledge to improve lives
Difference between correlation and causation?
Correlation shows a relationship but does not tell you WHY the two are related. Causation explains the cause
Empirical Approach
using a collection of data to base a theory or conclusion
General Research Process Steps (7)
- Develop question
- Generate hypothesis
- Form operational definitions
- Choose a design
- Evaluate ethical issues
- Analyze and interpret data
- Report results
Why do you need literature review during the hypothesis development process?
Q
What is a construct? Give an example
Concepts that are clearly defined; the concept that is being tested
Ex: emotion, memory, mood
IV
Altered or manipulated
2 levels
Experimental/control
What is an operational definition? Example?
How the construct will be measured?
Ex: by their reading ability
What is the difference between basic and applied research?
Basic=lab setting
Applied=real world setting
Selecting a sample: inclusion
H
Selecting a sample: exclusion
Q
Selecting a sample: power
Q
Selecting a sample: representative
Q
Reliability
What is it?
What are the three types?
How consistent a measure is; if you measure many times, will the results be the same?
- Internal consistency
- Test-retest
- iInter-rater
Validity
What is it?
4 types?
Whether it measures what it’s supposed to measure
- Face
- Convergent
- Discriminant
- Criterion-prediction
Difference between reliability and validity?
Reliability has to do with consistency while validity has to do with whether or not it measures what it is supposed to measure
What is external (or ecological) validity?
Results applicable to the real world
What is quantitative data?
Data that is translated into and analyzed into numerical data
What is qualitative data? Ex?
Subjective data such as a case study, ex testing memory.
What are confounds?
How do experiments try to eliminate them? (2ways)
Other variables that may be causing an effect on another
- Manipulate only 1 factor at a time
- Measure outcome variable
Converging evidence
Best method to confirm evidence
Evidence from various sources that lead to the same conclusion
Replication
Doing the study over again the exact same way to support theories further
Multi-method approach
1
Components of informed consent
What does IC ensure?
What does it cover?
- Competence, knowledge and volition
- Who you are, what you’re doing, why, benefits/risks, what they’ll be asked to do and for how long, voluntary participation, no penalty for withdrawal
When is informed consent required?
G
When is informed consent not required?
Research will not cause any distress
Observational research
