Conclusion

Intro of TV had little effect on children's behaviour - if anything it was more pro social. Authors concluded that this may reflect strong community rather than the introduction of tv having no effect.

6 of 8

Strengths?

Inter-rater reliability improves the objectivity. Good application because its relevant to today's society. High Ecological validity because it was a real life situation. Consent was gained from the parents.

7 of 8

Weaknesses?

Generalisation is low because it was a small sample. Can't replicate the situation. Construct validity was low because they didn't record the children's viewing habits.
