Paper 2 - Non-Experiments (research methods) Flashcards
What is a Covert observation:
- (Undisclosed) observation and consists observing people without their knowledge. Ppts are informed of their involvement after the observation takes place
Strength of Covert observations:
- Investigator effects are less likely to occur as the investigator is hidden. As a result of this there is less chance if demand characteristics occurring (where ppt tries to guess the aim)
Weakness of Covert observations:
- Ethical issues as the ppts are unaware they are being observed so the investigator is unable to fully gain informed consent. So an assessment should be made by the investigator before the observation begins to ensure no laws are broken
What are Overt observations:
- Observations are ‘open’ and the ppts know/aware that they are being observed
Strength of Overt observations:
More ethical than Covert observations as the ppts are aware that their behaviour is being observed. They are able to inform them of the aim and thus obtain informed consent and allows ppt the right to withdraw from the research
Weakness of Overt observations:
- Possibility of order effects as a possible bias could occur when he researcher influences the behaviour of the ppts therefore the ppts may change their natural behaviour through demand characteristics to act in the way the aims deems to
What are participant observations:
- The person who is conducting the observation also takes part in the activity being observed. Can be either Covert + Overt
Strength of participant observations:
The researcher is able to gain depth data/understanding of behaviour as they are able to gain a unique insight into the question asked. Meaning a comprehensive understanding of human behvaiour can be achieved
Weakness of participant observations:
Greater possibility of investigator effects the presence of the researcher might change the behvaiour of the ppts through demand characteristics. Consequently natural behaviour is not being observed thus reducing the internal validity
What are Non-participant observations:
- The person who is conducting the observation does not participate in the activity being observed
Strength of Non-participant observations:
Investigator effects are less likely compared to participant observation. The researcher observing from a distance (not visible) Therefore the behvaiour is more likely to be natural human behaviour
Weakness of Non-participant observations:
Due to lack of proximity the researcher might miss behaviours of interest. Meaning the unique insights of the human behaviour being observed will be overlooked
What are Naturalistic observations:
- Observation carried out in an unaltered setting in which the researcher does not interfere in any way and merely observes the behavior
Strength of Naturalistic observations:
High level of ecological validity can be reached as the researcher records naturally occurring behvaiour. Therefore the behaviour being recorded is likely to be more representative of everyday activities/life
Weakness of Naturalistic observations:
Issues ascertaining reliability as because the environment is naturally occurring therefore almost impossible to replicate the study so research attempting to understand human behaviour using naturalistic observations often lacks replicability
What are Controlled observations:
- Conducted under strict conditions (lab setting) where EVs will be controlled to avoid interference with behaviour being observed
Strength of controlled observations:
Can be replicated to check for reliability as the variables are very controlled. Meaning standardized procedures, manipulation of the IV and control over EVs can be repeated by researchers to assess the reliability
Weakness of Controlled observations:
Have a low level of external validity as researcher records behvaiour in an artificial environment. The high level of control means the setting can feel unnatural as a result. Therefore no longer representative of real life causing the ecological validity of the findings to be questioned
What are Structured observations:
- Researcher uses coded ‘schedules’ according to a previous agreed formula to then organize the data into behaviour categories
Strength of structured observations:
The researcher can compare behaviour between participants and across groups due to the operationalized behavioral categories makes the coding of the data more systematic and when there is more than one observer the schedule increases inter-observer reliability
Weakness of structured observations:
Problems with ascertaining high internal validity as the researcher may miss some crucial behaviors. Therefore the findings may not provide the full picture about the behvaiour as they could lack the finer details and this is a problem as what was intend to be measured was not achieved
What are unstructured observations:
Involves every instance of the observed behaviour being recorded and described in as much detail as possible
Strength of unstructured observations:
Richness of data is obtained since behaviour is recorded in great detail so researchers are able to obtain a comprehensive view of human behaviour. Therefore adding to the internal validity
Weakness of unstructured observations:
They are prone to observer bias due to the lack of objective behaviour categories this could mean the observer then only records behaviour which is of subject value to them and not a valid representation of what is being displayed. So there may be a problem with inter-observer reliability as there is a lack of consistency in the observations recorded
What is event sampling:
- The observer decides on specific events (behavioral categories) relevant to the investigation. These relevant events (behaviour categories) are recorded every time they happen within a set period of time E.g. when observing aggression at a football match, recording a tally every time they see an aggressive act occur within the full time period (90minutes)
What is time sampling:
Tallying behaviour in a set interval E.g. every 2 minutes
Recording what behaviour at every 2 minutes time interval, over a 1 hour period E.g. this would mean the researcher would tally 30 behaviors within an hour
What are behavioral categories in observations:
- When you have decided which type of observation to use you also need to create operationalised behavioral categories which mean what specific behaviour will you look for
3 reasons why you use behavioral categories:
1) Provides a clear focus for observation
2) Allows for more objective research/data recording as the behaviour observed is clearly measurable
3) Allows observers to tally the behaviour in groups
What are questionnaires:
- Questionnaires from part of surveys, which involves asking a large sample of people for information on a specific topic.
The purpose of surveys is to get a good representation of the target population using a large sample therefore making it able to generalize results to the rest of the population
Strength of questionnaires:
They can tackle sensitive issues such as homosexuality as ppts can remain anonymous by not asking for their name meaning answers are more likely to be honest and are happier to disclose. Increasing the internal validity.
Weakness of questionnaires:
Questionnaires could lead to social desirability this is where people may lie to present themselves in the best possible light. Therefore lowering the internal validity of the research.
What are Open questions:
These are questions which ppts can answer using their own words. They can express their views of their own behaviour and responses tend to include greater detail. Qualitative Data.
Strength of Open questions:
There is less chance of researcher bias this is because the questionnaire is anonymous as the ppts can answer questions in their own words without input from the researcher
Weakness of Open questions:
Participations may answer in a socially desirable way where they try to portray themselves in the best way possible to the researcher. Means open questions may lack validity as it is not their natural response
What are closed questions:
These are questions which mean that ppts responses are fixed e.g., Yes or No or rating scales. Quantitative Data.
Strength of Closed questions:
The data collected is quantitative makes it easy to analyse the results statistically or in a graphic format as direct comparisons can be made between groups of individuals. So the researcher can look for patterns and trend in data
Weakness of Closed questions:
By sticking to a presidented list of questions the researcher is unable to pursue and explore responses. Closed questions also produce response bias as the ppts don’t always read the questions properly so data may lack internal validity
What is reliability
- Refers to the ability to repeat/ replicate a study in a similar condition to gain consistency results
