Informal parental traffic training and children's traffic accidents.

The aims of the present study were (a) to assess the relationship between informal traffic training by parents and their children's involvement in traffic accidents and (b) to identify factors contributing to this relationship. The first two studies involved questionnaires on informal parental traffic education, the child's exposure to traffic and traffic-related accidents. Both studies showed that rate of accidents increased with training, particularly for outdoor training.

Number-word sequence skill and arithmetic performance.

In two studies, the role of the number-word sequence skill for arithmetic performance was investigated. In the first, children between 4 and 8 years of age were asked to count forward and backward on the number-word sequence and to solve arithmetic problems followed by post-solution interviews about solution procedures. The results demonstrated that the number-word sequence skill predicted both number of problems solved and strategy to solve the problems.
