Abstract
We present a novel method for deriving solution strategies used when solving rotation tasks. Process-based findings about physical rotation are obtained from an analysis of how angular disparity between stimuli changes over time. Data on angular disparity was gathered through a study on mental and physical rotation with 37 primary school students between the ages of 8 and 11. For controlling physical rotation, students used touch-based input on our iOS app Rotate it!, which also logged their interactions. Data on changes of angular disparity was used in the construction of Markov models. The models were employed to generate sets of synthetic angular disparity time courses, based on which we identified three distinct rotation-based solution strategies. Our analysis has implications for understanding processes involved in physical and mental rotation alike. It helps to lay grounds on which novel interactive diagnostic and training tools for spatial skills can be developed.

Abstract
One of the frequently examined design principles in multimedia learning is the personalization principle. Based on empirical evidence this principle states that using personalized messages in multimedia learning is more beneficial than using formal language (e.g., using ‘you’ instead of ‘the’). Although there is evidence that these slight changes in regard to the language style affect learning, motivation and the perceived cognitive load, it remains unclear, (1) whether the positive effects of personalized language can be transferred to all kinds of content of learning materials (e.g., specific potentially aversive health issues) and (2) which are the underlying processes (e.g., attention allocation) of the personalization effect. German university students (N = 37) learned symptoms and causes of cerebral hemorrhages either with a formal or a personalized version of the learning material. Analysis revealed comparable results to the few existing previous studies, indicating an inverted personalization effect for potentially aversive learning material. This effect was specifically revealed in regard to decreased average fixation duration and the number of fixations exclusively on the images in the personalized compared to the formal version. These results can be seen as indicators for an inverted effect of personalization on the level of visual attention.
