Definition
Cross-breaking research, also known as lateral research, is a comparison between several different groups (usually different ages) on a particular point.
For example, in order to understand the child's computing power, you can give a group of 6-year-old children within 20 or 100 questions, let them calculate, then find out the level of operations of this age. Another example, a classic small experiment: Choosing three ages - two months, five months, eight months, putting towels on their face as arguments (stimulating variables): two The child is blindly struggling, and the five-month child is arrested in the direction of the towel, and the eight-month child will not pull the towel and feel fun. The advantage of the cross-breaking method is to identify different levels or characteristics of the same age or different age psychological development in a short time, and analyze the development law. But due to short time, it is difficult to see the continuous process and key transformation points.
Excellent point of cross-breaking research
1. Advantages of cross-breaking research:
The duration is short, you can have the development level of different age children's psychology in a short time .
2. Disadvantages of transverse research:
See the continuity of the same body development, intergeneration and age factors confusion.
