Sequential processing in comprehension of hierarchical graphs

Hierarchical graphs represent the relationships between non-numerical entities or concepts (like computer file systems, family trees, etc). Graph nodes represent the concepts and interconnecting lines represent the relationships. We recorded participants' eye movements while viewing such graphs to test two possible models of graph comprehension. Graph readers had to answer interpretive questions, which required comparisons between two graph nodes. One model postulates a search and a combined search-reasoning stage of graph comprehension (two-stage model), whereas the second model predicts three stages, two stages devoted to the search of the relevant graph nodes and a separate reasoning stage. A detailed analysis of the eye movement data provided clear support for the three-stage model. This is in line with recent studies, which suggest that participants serialize problem solving tasks in order to minimize the overall processing load. Copyright © 2004 John Wiley & Sons, Ltd.     

God Takes our Place: A Religious-Philosophical Approach to the Concept of Stellvertretung

What does it mean to say, theologically, that God takes our (human beings') place (Stelle)? In himself becoming human (the incarnation), does God enter into joys and needs, into the possibilities and the limitations of the human, in such a way as to take them all to himself? Or does he, specifically, take the blame of all people? Or only that of those who believe? Or is it something else again that is meant? What does it mean to say that ‘God stands up for us’ is the event of salvation– a claim which the church has in mind with its central dogma of the incarnation of God in Jesus Christ? How is human Stellvertreten, occurring in different forms, connected with the divine Stellvertreten? What does the word ‘Stelle’ (of humans) mean at all?
