Q

What are naturalistic observations

A

Covert
- observing participants
- ‘under cover’
- researchers identity is kept hidden
- purpose of the study is hidden from group

Overt
- observing participants
- participants know they are being watched

Participant
- observing participants
- become part of the group

Non-participant
- observing participants
- researcher is not a part of the group

General
- natural environment - measuring natural and spontaneous behaviour
- can record data by tallying u- behaviours or filming or writing down what you see

Q

why would you use observations? +

Study These Flashcards
A

covert: good to study groups that can’t be studied otherwise
+ collects impossible data
+ high ecological validity
+ less demand characteristics

overt: good to study groups if you want deeper analysis and want to ask questions
+ allows participants to be informed
+ data triangulation with interviews

non-participant: good if your investigating something where its not possible to interact with participants
+ easy to collect
+ observational data can be cross checked to establish credibility

participant: good if you want to interact with participants and gain deeper insight
+ detailed information
+ good for exploring sensitive information
+ avoid researcher bias

naturalisitc: good when you want to keep behaviour as natural as possible
+ high ecological validity
+ high credibility
+ testing something that could be developed in a more controlled setting

controlled: good when you want to ‘set up’ a situation
+ highly controlled
+ standardised procedure
+ avoids ethical consideration of consent

24
Q

why would you use interviews? +`

Study These Flashcards
A

semi structured: when you want flexibility but have an idea of what your going to ask
+ build rapport to gain futher insight
+complex questions
+ easy to record

unstructured:
+ good rapport
+ easier for researcher to check understanding
+ can explore new areas and generate rich data

25
why would you use questionaire/survey? ++
why would you use this? - quick and easy from lots of participants + less social desirability bias as anonymous + anonymity + quick, easy, cheap + collects a large amount of data + standardised questions, higher reliability + good for sensitive topics
26
why would you use a focus group?
why would you use this? - when you need to collect the view of more than one person +effective for cross-cultural studies + everyone can participate, even those who can't read and write + people have opportunities to develop their own ideas + time saving
27
why would you use a case study? +
why would you use this? to obtain information on a specific case study that would be unethical to replicate + rich information + insight for further research + impratical or unethical to replicate
28
why would you use a correlation? +
why would you use this? when its not possible to manipulate variables - used to test things that we wouldn't be manipulate - produces quantitative data which is easy to analyse and compare.
29
what is informed consent?
the participant needs to be informed of the aims and the objectives of the research and needs to give their consent
30
what is the right to withdraw?
it's the participants choice if they won't continue to participate in research at any time, and this should be in the consent form
31
what is protection from harm?
research that causes anxiety, stress or pain or any long-lasting change is not permitted. if there is this, researchers must recitfy using methods such as, supplying therapy
32
what is a debrief?
when the research is over, every effort must be made to return participants to their original state. this must be explanations of the study and the role participants had in it
33
what is deception?
misleading or misrepresenting the participant in any way. unjustified deception is generally not permitted.
34
what is confidentiality?
information is kept private, but it's technically possible for researchers to figure out a participant's identity
35
what is privacy?
no participant should be made identifiable by the research published
36
what is anonymity?
it should be impossible for anyone, including researchers, to connect participants with their data
37
what are the ethical considerations in reporting the data?
- informed consent: permission must be sought if the participant is under the age of consent - deception: researchers should inform participants how they intend to use the results - debrief: participants should be debriefed about how the results will be reported - right to withdraw: participants should have the right to withdraw their data if they wish - anonymity: characteristics of the sample should not be included, especially when the matter is sensitive when reporting data - protection from harm: it may be necessary to provide support to most vulnerable participants
38
what are the ethical considerations when applying the results?
- awareness of reseacher's own biases and expectations which could have influenced the the findings, especially policies - results cant be changed or overstated in order to support an agenda - replication of findings by an independent researcher to test how credible the research is before being applied - consider scope and generalisation of study to other contexts, resulting in inappropriate conclusions being generalised to others - consider whether characteristics of sample are similar to community, and researchers should be careful to not assume that findings can be generalised to all populations - findings shouldn't be used to allow political or buisness groups to target community. however, results could be used to provide advice, education and outreach programmes.
39
if the data is quantitative, is it transferability or generalisability?
generalisability
40
if the data is qualitative, is it transferability or generalisability?
transferability
41
what is the definition of generalisability?
the extent to which the findings from a sample are applicable to a broader population
42
what is the definition of transferability?
the extent to which the results can be considered relevant to other contexts and settings
43
how does sampling affect transferability/generalisability?
is the sample representative of the target population? size, characteristics, method etc
44
how does controlling variables affect transferability/generalisability?
limits extraneous variables to increase validity of findings, as it's more accurately applied
45
how does replication affect transferability/generalisability?
increases reliability as it can be replicated with other people, cultures and different timepoints, and same results can be found
46
how is population validity affect transferability/generalisability?
the extent to which the results are valid and applicable to the population, beyond the study. e.g characteritsics of a sample (culture, size and features)
47
how does ecological validity affect transferability/generalisability?
the extent to which findings can be generalised to real life settings: does the research method replicate real environments?h
48
how does remporal validity affect transferability/generalisability?
refers to the validity of thr findings over progression of time. when was the research carried out? has anything changed in society that stops this?
49
how does triangulation affect transferability/generalisability?
measuring the same behaviour, using multiple methods/researchers/viewpoints. if the research reaches the same conclusion, it's more accurate to apply and generalise to a wider population.
50
how does bias affect transferability/generalisability?
any researcher bias means it's difficult to accurately generalise/transfer
51
what three features do we use for transferability/generalisability?
- sample - triangulation - bias
52
credibility
the extent to which the conclusions reflect the meanings as they are only described by the participants
53
what is bias?
a systematic error arising from sampling, data collection or data analysis
54
what increases credibility
- research journal - peer reviews: getting an expert to check and verify the study - independent scrutinizers: people outside of the study - triangulation: data, method and theoretical
55
what decreases bias?
- pilot study - use of placebo - operationalise variables - double blind - counterbalancing - matched pair designs - using deception - lower demand characteristics - random sampling methods
