Developmental Area Flashcards
Bandura external validity
Low: restricted sample, all from same nursery and area. Ethnocentric.
Bandura internal validity
High: testing aggression due to matched participants design, this rids of participant variables potentially affecting accuracy
Bandura ecological validity (external)
High: real life setting the children are in most days, playing with toys replicates a real life task
Bandura internal reliability
High: controls and standardised procedure (“repeatedly punch it in the nose” “kick him” “pow”)
Bandura Inter-rater reliability
High: correlation co-efficient rating 0.89 (pre-testing opinions agreed on)
Inter-scorer agreement with second observer
Bandura external reliability
Low: 6 per condition is not enough to establish an effect/pattern. Small sample
Bandura background/context
Behaviourists say you learn from environment. Developed concept of social learning theory. Observing an adult role model and imitating
Bandura aim
See whether children would imitate aggressive behaviour when given the opportunity even when in a different environment to the example they saw and without the male role model present
Bandura hypotheses
- Subjects exposed to aggressive model would reproduce aggressive actions resembling those of the model
- Observing non aggressive behaviour would have inhibiting effect on subsequent actions
- Higher imitation with same sex model
- Boys would be more predisposed to show aggression than girls
Sample: opportunity
72 children aged 3-5 from Stanford University Nursery (6 in each condition) equal gender split
Bandura experiment type and design
Field & matched participants
Bandura pre-testing
Rated in 4 areas by teacher and experimenter
-physical, verbal, aggression to inanimate objects & aggression inhibition
R=0.89 (high internal-rater reliability)
Bandura IVs and model conditions
Same sex/different sex Male/female children Aggressive/non aggressive model Model conditions: Aggressive male Non aggressive male Aggressive female Non aggressive female No model
Bandura findings
Children exposed to aggressive models showed more imitative aggressive behaviour
Exposure to non aggressive models would have inhibiting affect on the child’s behaviour
Boys more likely to imitate same sex model than girls
Boys more physically aggressive, girls more verbally aggressive with female model
Bandura qualitative findings
“That ain’t no way for a lady to behave”
“He’s a good fighter like daddy”
Western cultures may effect boys to idolise the violent “heroes” and women may feel more comfortable with verbal aggression
Bandura conclusions
Observing behaviour produces imitative behaviour
Disproves skinner’s view you had to view behaviour several times before imitating
Bandura ethical issues
No informed consent from parents (only teachers)
Expose children to harm when watching aggression
Children weren’t aware they could ‘withdraw’ from something an adult was instructing
Deception
Debriefing- didn’t inform parents after
-however did keep confidentiality-
How is developmental area similar to the social area
Discusses nurture as an influence on behaviour
Use controlled research methods
Ethnocentric (different upbringings)
How is developmental area different from the social area
Considers many different influences on behaviour
Studies mainly on children
Self report methods
Longitudinal
What are strengths of the developmental area
Useful& good real life application
(Education)
Nature v nurture relevance
Quantitative and qualitative
Reduce participant variables as they use same group for longer period of time
Weaknesses of the developmental area
Can be unethical as a lot of research is carried out on children. Children more sensitive to harm
Children may not be reliable use of self report or able to express themselves
Ethnocentric upbringings- cultural differences
Small samples are not generalisable
Defining characteristics of the developmental area
Behaviour changes over time
Research on children
Nature v nurture
Kohlberg’s aims
Wanted to provide research that would back up his theory of moral development inspired by Piaget
Kohlberg’s research method
Longitudinal- follows participants for long periods of time
Interviews
Kohlberg’s USA sample
75 boys aged 10-16 until they were 22-28 years old. Followed same boys for 12 years
Kohlberg’s procedure
Every boy provided with moral dilemmas every 3 years
Ranked the answers boys gave from 1(least morally developed) to 6(most morally developed)
Formed his theory of stages of moral development
