Abstract We use the technique developed in Moughal’s doctoral thesis to analyse the joint spike transition, revealing new groups of world-lines which undergo distinct transitions, and correcting misconceptions about spikes.

The Individual

In Spain doctoral studies underwent a major legal reform in 1998. The new legislation has brought together the criteria, norms, rules, and study certificates in universities throughout the country, both public and private. A brief description is presented here of the planning and structuring of doctoral programs, which have two clearly differentiated periods: teaching and research. At the end of the 2-year teaching program, the individual and personal phase of preparing one's doctoral thesis commences. However, despite efforts by the state to regulate these studies and to achieve greater efficiency, critical judgment is in order as to whether the envisioned aims are being achieved, namely, that students successfully complete their doctoral studies. After this analysis, we make proposals for the future aimed mainly at the individual period during which the thesis is written, a critical phase in obtaining the doctor's degree. Not enough attention has been given to this in the existing legislation.

Close Relationship

The solution strategies of preschool children solving mental-rotation tasks were analyzed in two studies. In the first study n = 111 preschool children had to demonstrate their solution strategy in the Picture Rotation Test (PRT) items by thinking aloud; seven different strategies were identified. In the second study these strategies were confirmed by latent class analysis (LCA) with the PRT data of n = 565 preschool children. In addition, a close relationship was found between the solution strategy and children’s age. Results point to a stage model for the development of mental-rotation ability as measured by the PRT, going from inappropriate strategies like guessing or comparing details, to semiappropriate approaches like choosing the stimulus with the smallest angle discrepancy, to a holistic or analytic strategy. A latent transition analysis (LTA) revealed that the ability to mentally rotate objects can be influenced by training in the preschool age.
