This is the Proceedings of the "International Conference on Motivation 2012" carried out by the Special Interest Group "Motivation and Emotion" of the European Association for Research on Learning and Instruction (EARLI) in cooperation with the German Institute for International Educational Research (DIPF) and the Goethe University Frankfurt.

Lernverhalten und Lehrorganisation werden als komplementäre Komponenten einer Lernkultur betrachtet. Auf der Grundlage eines Modells der Lernmotivation wurde das Lernverhalten Studierender mit einer Latenten Klassenanalyse untersucht. Die Gruppenprofile wurden zu Noten und Workload-Daten einer Zeitbudget-Erhebung in Bezug gesetzt. Es zeigte sich, dass nur eine Gruppe Studierender ihren Lernprozess unter herkömmlichen Bedingungen selbstbestimmt erfolgreich gestaltet. Eine andere Lehrorganisation könnte Lernende anderer Typen der Motivationsregulation besser unterstützen.
We introduce a computational model of the negative priming (NP) effect that includes perception, memory, attention, decision making, and action. The model is designed to provide a coherent picture across competing theories of NP. The model is formulated in terms of abstract dynamics for the activations of features, their binding into object entities, their semantic categorization as well as related memories and appropriate reactions. The dynamic variables interact in a connectionist network which is shown to be adaptable to a variety of experimental paradigms. We find that selective attention can be modeled by means of inhibitory processes and by a threshold dynamics. From the necessity of quantifying the experimental paradigms, we conclude that the specificity of the experimental paradigm must be taken into account when predicting the nature of the NP effect.
The neural correlates of developmental dyslexia have been investigated intensively over the last two decades and reliable evidence for a dysfunction of left-hemispheric reading systems in dyslexic readers has been found in functional neuroimaging studies. In addition, structural imaging studies using voxel-based morphometry (VBM) demonstrated grey matter reductions in dyslexics in several brain regions. To objectively assess the consistency of these findings, we performed activation likelihood estimation (ALE) meta-analysis on nine published VBM studies reporting 62 foci of grey matter reduction in dyslexic readers. We found six significant clusters of convergence in bilateral temporo-parietal and left occipito-temporal cortical regions and in the cerebellum bilaterally. To identify possible overlaps between structural and functional deviations in dyslexic readers, we conducted additional ALE meta-analyses of imaging studies reporting functional underactivations (125 foci from 24 studies) or overactivations (95 foci from 11 studies ) in dyslexics. Subsequent conjunction analyses revealed overlaps between the results of the VBM meta-analysis and the meta-analysis of functional underactivations in the fusiform and supramarginal gyri of the left hemisphere. An overlap between VBM results and the meta-analysis of functional overactivations was found in the left cerebellum. The results of our study provide evidence for consistent grey matter variations bilaterally in the dyslexic brain and substantial overlap of these structural variations with functional abnormalities in left hemispheric regions.
