Define content analysis
Observational study which enables indirect study of behaviour by examining visual, written or verbal communication material (media such as books or TV)
Quantitative, qualitative or both
What does the researcher have to decide in sampling method for a content analysis?
- Books - looking at every page or just every fifth page? (E.g.)
- Comparing books - does the researcher select books randomly or identify certain characteristics (e.g. all biographies or romantic fiction)
- Adverts - time or event sampling?
Define coding in content analysis
Placing quantitative or qualitative data in categories (behavioural categories)
How may data from a content analysis be represented?
- Quantitative - count instances of a behaviour
- Qualitative - describe examples in each category
Define thematic analysis
Technique used when analysis qualitative data
Themes or categories identified + data is organised according to these themes
Outline what is involved with thematic analysis
- Qualitative data is difficult to summarise —> summarised by identifying repeated themes in the material
- Read + reread data, trying to understand meaning communicated + the perspective of the participants | NO NOTES
- Break data into meaningful units - small bits of text which can independently convey meaning
- Assign a label or code to each unit (INITIAL CATEGORIES) - each unit may be given 1+ code/label
- Combine simple codes into larger categories/themes + then instances can be counted or examples provided
- CHECK OVER CATEGORIES by collecting new data + applying the categories
Define case study
Research method than involves in-depth study of a single individual, institution or event
Outline what is involved in a case study
- Uses information from a range of resources (e.g. person concerned, family + friends)
- Interviews, observed while engaging in family life, IQ/personality tests or questionnaires to produce psychological data about the target person or group
- May use experimental method to test what the target person/group can/can’t do
- Usually LONGITUDINAL
- Qualitative - but quantitative is possible (e.g. scores from psychological tests)
- IDIOGRAPHIC APPROACH
Give an example of a case study
- Phineas Gage
- 1848, was working on construction of American railway + tramping iron drove through his skull
^— survived + could function fairly normally - HOWEVER affected personality - friends said he was no longer the same man
- Case was important in development of brain surgery to remove tumours because it showed some parts of the brain could be removed w/o fatal effect
Define reliability
Consistency of findings from in investigation - the consistency of measurements
Would expect any measurement to produce the same/CONSISTENT data if taken on successive occasions
State two ways of assessing reliability
- Test re-test
- Inter-observer
Explain the test re-test method
The same test/ questionnaire is given to same person (or people) on 1+ different occasions
If results = same/similar: reliable
Explain inter-observer reliability
- 2+ Observers compare data from independent observation + record of same person
E.g. Ainsworth’s Strange Situation
State 4 ways of improving reliability
- Questionnaires
- Interviews
- Experiments
- Observations
Explain questionnaires in improving reliability
- Questionnaire that produces low test-retest reliability may require some items to be deselected or rewritten
- Researcher may replace open questions with closed questions which are less ambiguous
Explain interviews in improving reliability
- To ensure reliability in an interview, use the same interviewer each time
- If not, all interviews must be trained (e.g. to avoid questions that are leading or ambiguous)
Explain experiments in improving reliability
- Lab experiments often described as ‘reliable’ due to strict control over many aspects of procedure
^— e.g. instructions participants receive and the conditions in which they are tested (STANDARDISATION)
Explain observations in improving reliability
- Behavioural categories should be easily measurable (less vague - pushing rather than aggression) + no overlap (hugging and cuddling)
Define validity
The extent to which an observed effect is genuine
State 2 ways of assessing validity
- Face validity
- Concurrent validity
Explain ‘face validity’ in assessing validity
- The extent to which test items look like what the test claims to measure
- ONLY REQUIRES INTUITION
E.g. whether the questions on a stress questionnaire are obviously related to the stress
Explain ‘concurrent validity’ in assessing validity
- Means of establishing validity by comparing an existing test or questionnaire with the one you are interested in
^— participants given both measures at the same time + then scores are compared
IF SCORES = SAME: VALID
State 4 ways of improving reliability
- Questionnaires
- Interviews
- Experiments
- Observations
Explain questionnaires in improving validity
- Lie scales control for effects of social desirability bias - respondents assume data is confidential
Lie scale: a question is asked, then rephrased and asked again later on
^— different answers indicate a lie, which similar answers indicate the truth
