- Pro-social Behaviour - Developmental Factors
- McKenna & Ossoff (1998)
- Asked children aged 4-10 about moral messages in an episode of power rangers
- Most of the children understood there was a lesson to be learned, but only 8-10 year olds could identify it.
- Younger children focused on fighting.
- Study supports the developmental factors explanation as the children's age influences the understandingof moral messages
- Large age range
- Lab experiment - low external validity
- High control of variables
- Rosenketter (1999)
- Found that when interviewed only 1/3 of year 1's grasped the moral idea behind the episode of either the Cosby Show or Full house, but 1/2 of year 3's managed to grasp it.
- Supports the developmental factors theory as it proves that age is important in determining the media's influence.
- Lacks external validity - lab experiment
- May be social desirability from interview
- Culture bias as it was done in the USA so it cannot be generalised worldwide
- Does have a high control of variables
- McKenna & Ossoff (1998)
