Flashcards in Lecture 2: Science Of Behaviour Health And Development Deck (19)
What does good research consist of?
What does a theoretical framework consist of?
Organising and explaining observations, and a hypothesis that fows
What does a standard procedure mean?
A procedure which is the same for all participants except the variable to test the hypothesis
What is generalisability?
The results should be representative of the population, the procedure should be sensible
What is an objective measurement allow?
Consistent results, valid measurements. E.g. Candidate has asthma if they have had more than x number of attacks within a certain period of time
What is an experiment an effect of?
Independent and dependent variable
What are the 6 components of an experiment?
2 identify variables
4 sorting participants
5 results: statistical techniques
6 draw conclusions.
What are some issues with experiments? How can these be reduced?
Bias (reduced by placebo treatment, or by double blind studies)
What is a correlation study used for?
Finding casualties/explanations e.g. High blood pressure and habits to mange stress
Comparing beliefs, behaviours, abilities at one point in time
What types of correlation studies are there?
What is a naturalistic observation and what are its advantages and disadvantages?
Observe in natural setting - not controlled
+ collect natural data
- must wait for behaviour to occur naturally, this may take some time
What is a laboratory observation and what are its advantages and disadvantages?
Where you observe in a lab where extraneous variables can be controlled and specialised treatment can be used
+ better control of outside factors as more precise equipment can be used
- surroundings may affect results - skewed data
What is a case study and what are its advantages and disadvantages?
Where you observe one or a few subjects (people) for a long time
+ it is the only method available for weird cases
- may generalise results
What is a survey and what are its advantages and disadvantages?
Where you collect data using questionnaires/interviews, however the sample must be representative
+ can collect information regarding attitudes and beliefs
- subjects may lie or mislead, resulting in false data
What is a longitudinal study and what are its advantages and disadvantages?
A study which follows a subject over time to see their development/progress
+ we can see changes happen in the individual I.e. it's more precise
- takes time
What is a cross sectional study and what are its advantages and disadvantages?
A study where we can collect data from different people in different age groups at one point in time
+ it's fast
- we can't determine changes within an individual, so can have different results
What is cross cultural research?
A study which Determines whether findings apply to other cultures as well
Requires naturalistic observation, replication of experiments with people from different cultures and questionnaires
What are some ethical issues that may arise with research?
Using children as subjects
