Pt1
Kholberg gave participants several dilemmas related to 25 different moral concepts. These measured reasons why they might follow moral rules and other concepts such as the value of life.
Pt2
The children were given the same moral dilemmas every 3 years over a 12 year period to see hoe there responses and reasoning changed as they got older.
How was it longitudinal
Because the same children were studies every 3 years
Strengths of longitudinal
Allows researchers to see changes in each participant
Controls for participants variables
Weaknesses of longitudinal
Practical difficulties as you have to wait several years
Extraneous variables ( ur bringing) can influence behaviour
