Lecture 2: Science Of Behaviour Health And Development Flashcards
What does a theoretical framework consist of?
Organising and explaining observations, and a hypothesis that fows
What does good research consist of?
Theoretical framework:
Standard procedure:
Generalisbility:
Objective measurement:
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?
1 hypothesis 2 identify variables 3 method 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?
Cross sectional Longitudinal Naturalistic observations Laboratory observations Surveys
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
