Quizplus · Accepted Answer

The procedure described is an example of a longitudinal design, which involves testing the same group of participants over a period of time to examine changes or stability in a particular characteristic or behavior. The other options (A, B, and D) are not applicable to the described procedure. A cross-sectional design involves testing different age groups at the same point in time, a trajectory technique involves examining the patterns of change over time for a group of individuals with a similar starting point, and the centration technique refers to a cognitive limitation where a child focuses on only one aspect of a situation and ignores other relevant information.
