Exam Flashcards
ad and dis of experimental research design
ad -
* random allocation increases external validity
* maximise control over extraneous variables to help determine the impact on the dependant variable
* controlled setting = easy replication
*cause and effect relationship is determined
dis -
* may be unethical to manipulate variables
* controlled setting may not replicate real world = decrease external validity
experimental research design
- presence of a control group
-random allocation
-hypothesis testing
pre and post testing - cause and effect relationship established
- controlled environment such as labs
quantitative observational research design
- Iv not manipulated
research in a natrual setting - can determine associations but not cause and effect
ad ad dis of quantitative observational research design
ad
* allows research of unethical variables
* may allow bigger sample sizes
dis
* hard to replicate due to natural setting
* bias can affect results
qualitative research design
ad
* more convenient
* rich, detailed data
* very useful is not much information is known as discussion can be had and further research can build upon that
dis
* personal bias
* presence of facilitator can affect responses
types of data
objective quantitative data, subjective quantitative data, qualitative data
content analysis
collate and analyse qualitative data
- familiarity of data
- look for words, phrases relating to theme
- examine themes to find patterns
- identify common themes and label
- count number of times it occurs
- frequency table
reliability
replicability
source
source:
- experts = more trustworthy
- government should be trustworthy
- attractiveness
- fast talking = good
- loud speaking = confidence
channel
young more influenced by media
elderly = newspaper
direct experience stronger attitude
message
envolke strong message
music can exaggerate
observational learning
ARRM
attention - In order for learning to occur, observer must pay attention to the models behaviour.
retention - Observer codes observed behaviour information into long term memory.
reproduction - Observer must be able to reproduce model’s behaviour.
motivation - Observer expects positive reinforcement for modelled behaviour.
Example: model (parent) praises child (observer ) for washing dishes.
Reinforcement can be external (object reward) or internal (sense of accomplishment).
fixed interval
When an organism will be reinforced for a response only after a fixed time interval.
fixed ratio
When an organism must make a certain number of responses in order to receive reinforcement.
variable interval
When the reinforcement is given to a response after a specific, unpredictable amount of time has passed.
variable ratio
When the reinforcement is given after an unpredictable number of responses made by the organism.
contiguity
Reinforcement needs to be given/received as soon as possible after desired behaviour has been performed for behaviour to continue.
contingency
Reinforcer needs to be consistent for behaviour to continue.
prepardness
Some behaviours are ‘shaped’ more easily than others.
Reinforcement is shaped more easily than punishment because of the reinforcer being an incentive.
Food is a good example for animals and humans > ensures survival/pleasant taste, therefore more likely to continue reinforced behaviour.
factors affecting observational learning
gender of model
status of model
relationship with model
consequence after models behaviour
