ABSTRACT
Methodologically and theoretically, the variation displayed in Figures 4.2 and 4.3 may be understood as caused by age (maturation), generation and situation. In this case, age effects should be theoretically interpreted primarily in terms of development theory, which is able to provide a quite convincing interpretation of the fact that in early adolescence children move away from family-oriented to peer-oriented activities (for example, away from watching public service television together with their parents in the living room, instead turning to listening to music together with their friends, preferably somewhere out of reach of parental control). This type of temporal effect seems to be quite strong in our case.
