Research Methods Flashcards
Name the different types of observation
-Naturalistic observation
-Controlled observation
-Cover observation
-Overt observation
-Participant and non participant observations
What are the to ways of recording data in observational designs
-Recording everything (unstructured)
-categories (structured)
What are behavioural categories in observational designs
-Target behaviour broken down into observable components
What are the two types of sampling in observational designs
-Event Sampling
-Time sampling
What are independent variables
The thing you can change to see the effect on the dependent variable
What are dependent variables
The thing you are measuring
What are extraneous variables
Other things that could affect the DV that you are not measuring
What are confounding variables
Other variables that have affected your results
What is an aim in an experiment
A general expression of what the researcher wishes to investigate
What is a hypothesis
A predictive statement on what the researcher believes they will find, can be one tailed or two tailed
What are demmand characteristics
Any cue from the research situation or researcher that may expose the aims of the experiment causing participants to change their behaviour
What are investigator effects
Where investigators behaviour may effect the outcome of the experiment
Name the 5 research techniques for experiments
-Randomisation
-Standardisation
-Control groups
-Single bind
-Double bind
What are single bind experiments
Participant does not know the aim of the experiment
What are double bind experiments
The researcher and participant does not know the aim of the experiment
What are pilot studies
Trial run of the experiment on a smaller scale to resolve any problems
Name the 3 experimental designs
-Independent groups
-Repeated measures
-Matched pairs
Outline independent groups
-Participants in each condition of the experiment are different
-Participants should be randomly allocated to groups
Outline repeated measures
-The same participants take part in all of the conditions of the experiment
-Order of the conditions should be counterbalanced to avoid order effects
Outline matched pairs
Two groups of participants in different conditions paired on participant variables mattering to the experiment
Evaluate independent groups
-Participant variables are not controlled (HOWEVER can be solved by random allocation
-Less economical
-Order effects are not an issue
Evaluate repeated measures
-Order effects and demmand characteristics
-Participant variables controlled
-More economical
Evaluate matched pairs
-No order effects
-Cannot match participants perfectly
-Time consuming
Name the types of experiments
-Lab experiment
-Field experiment
-Natural experiment
-Quasi experiment
What are lab experiments
-Controlled setting
-EV’s and CV’s can be regulated
-IV manipulated and the effect on the DV is recorded
What are field experiments
-IV manipulated in a natural setting
-effect on the DV is recorded
What are natural experiments
-Experimenter does not manipulate the IV
-DV may be naturally occuring
What are quasi experiments
-IV based off pre existing differences (e.g age or gender)
-No one manipulates the IV
-DV may be naturally occurring or measured by the experimenter
Evaluate lab experiments
-High internal validity as EV’s and CV’s controlled
-Replicability easy
-Low external validity
-Demand characteristics
Evaluate field experiments
-Greater external validity as natural enviroment
-Low internal validity (less control)
-There may be ethical issues
