Research Methods Flashcards
What are the main differences from normal psychology?
- The questions themsleves
2. A specific population: criminals (except when looking at jurors)
What is an estimator variable?
variables present at the time of the crime that cannot be changed.
- age, lighting, sobriety, etc.
What is a system variable?
a. Parameters of an investigation that can be increased or decreased to ensure optimal effectiveness of a procedure
- how evidence is collected, questioning types, etc.
Define archival research, and list strengths and weaknesses
- study of existing data and documents
Strengths: allows us to look for a pattern, get an overview of a topic, all in a short period of time
Weaknesses: mostly qualitative, and not a lot of info may be available on a certain topic. Also, no variables to manipulate.
Define lab research, and list strengths and weaknesses
Standard experiments, manipulation of variables
Strengths: Random assignment, full control of variables
Weaknesses: very artificial, given nature of crime. often uses a niche pop like university students
Field research
Use of fictitious crimes, where unsuspecting people are interviewed after observing a face crime
Define a case study
a. Used when you seek to understand specific characters, such as serial killers
b. Very specific details, with a lot of specific information
c. Only a few people
Correlation designs
a. An assessment of the relationship between two or more variables
Experimental designs
a. Dependent and independent variables are assessed, and a causal hypothesis is made
Longitudinal designs
a. Used for risk assessment or certain types of treatment
b. Can also be used to assess the effectiveness of new police procedures
Meta-analysis
a. Used in the conception of the field
b. Used to identify variables of interest
What are three major considerations in ethics of psychology research?
- Risks vs. benefits ratio
- Minimal risk assessment
- Informed consent
When is deception used?
Only if the experiment would be otherwise invalidated or the results affected
Ethics of deception
- consent for use of data must be attained once the experiment is concluded
- Should only ever be used as a last resort: if any other approach will do, go that direction
- It is never ethical to use deception about a reward
Define a free-narrative interview
A. The participant responds to open-ended questions
B. The patient just talks without interruption by interviewer
C. Flow to questions and answers
