PSYCH PAPER 3 Flashcards
What are the ethical considerations that must be kept in mind when carrying out research?
informed consent
confidentiality
right to withdraw
no undue stress or harm
deception
debrief
Opportunity sample
Selective participants who are most easily available/accessible to the researcher
Time and cost effective
biased
self-selected sample/volunteer sample
participants are recruited on a voluntary basis, usually through advertising or word-of-mouth, and they self-select into the study
useful when the researcher has limited access to the population or when participants must meet certain criteria to be eligible for the study
May be biased
snowball sample
Participants are recruited through referrals by other participants of the study
used when the researcher is studying a hard-to-reach population, such as individuals with a stigmatized condition or those with limited access to resources
random sampling
Every member of the target population has an equal chance of being selected
Most unbiased method, since participants are chosen at random, and everyone has equal chance
stratified sampling
a variation of random sampling; the population is divided into subgroups and weighted based on demographic characteristics of the national population
purposive sampling
Participants are selected based on a specific criteria or characteristic
Aims to be representative of the population being studied
Cannot be generalized to wider population, since everyone has one shared particular something
quota sample
A sample deliberately constructed to reflect several of the major characteristics of a given population
theoretical sample
In qualitative research, a sample that helps the researcher understand or formulate a concept or interpretation.
laboratory experiment
Manipulation of one or more independent variables to investigate their effect on one or more dependent variable, which controlling other variables
Can help to establish a cause and effect relationship
Usually has a control condition + the IV conditions to establish comparisons
field experiment
Independent variables are still being manipulated by the researcher
Random assignment to conditions
Conducted in the natural setting where the behavior/phenomenon occurs
natural experiment
The experimenter cannot manipulate any variables
The independent variable already exists
The environment itself could be controlled
Non random assignment of participants
quasi experiment
Participants are based depending on a particular characteristics
Usually involves purposive sampling
Comparison of groups, usually a control group is used
Participants are not randomly assigned to conditions
No control of the IV
correlational study
Non experimental, we are analyzing the relationship between two variables
Use of data
Cannot establish a cause and effect relationship
case study
a detailed analysis over time of an area of interest (a case) to produce context-dependent knowledge; ex. an in-depth study of an individual, organisation, etc.
not a singular method but data is collected using method triangulation. uses different perspectives, collects rich data
case studies are a flexible approach, they can help to generate more research or more theories
potential risk for researcher bias, low generalisability because they are so specific
interviews
A researcher has a discussion with the participant one on one
Good way to obtain qualitative informations
More personal than a survey or a questionnaire or survey
questions, their wordings, and their order of administration are determined in advance
naturalistic observations
Observation of a phenomenon/behavior where it naturally/originally occurs
Can be covert or overt
Usually qualitative data is collected
triangulation
use of multiple methods or sources of data to study a particular phenomenon or research question
Increase validity and reliability
observation
the action or process of observing something or someone carefully or in order to gain information.
overt observation
Participants know they are being observed
Covert observation
observation in which the observer’s presence or purpose is kept secret from those being observed
structured interview
a research procedure in which all participants are asked to answer the same questions
semi-structured interview
Pre-prepared questions (everyone gets the same) that might be open ended
Can have space for follow up questions
Production of rich qualitative data
unstructured interview
Flexible and open type of interview, with space for spontaneity
The questions and the order in which theta re presented is not set
Interviewers can ask follow up questions based on the participant’s responses
Open ended
focus group
Small group of people brought together to answer questions in a moderated environment
Prompts of conversation shed light on the area of study
Usually bring together people based on a particular shared characteristic they have
