We performed an EEG graph analysis on data from 31 typical readers and 24 dyslexics, recorded while they were engaged in an audiovisual task and during resting-state. The task simulates reading acquisition as participants learned new letter-sound mappings via feedback. EEG data was filtered for the delta, theta, alpha, and beta bands. We computed the Phase Lag Index to provide an estimate of the functional connectivity between all pairs of electrodes per band. Then, networks were constructed using a Minimum Spanning (...) Tree, a unique sub-graph connecting all nodes without loops, aimed at minimizing bias in between groups and conditions comparisons. Both groups showed a comparable accuracy increase during task blocks, indicating that they correctly learned the new associations. The EEG results revealed lower task-specific theta connectivity, and lower theta degree correlation over both rest and task recordings, indicating less network integration in dyslexics compared to typical readers. This pattern suggests a role of theta oscillations in dyslexia and may reflect differences in task engagement between the groups, although robust correlations between MST metrics and performance indices were lacking.

One of the most controversial issues that divided Islamic philosophers and theologians during the Middle Ages was whether human beings would have a spiritual or bodily existence after death. The idea of a world of image was conceived as a solution, suggesting that there exists a world of non-physical bodies, beyond our earthly existence. This world may be reached in sleep, in meditation or after death.From the embryonic conception by Ibn Sina, to the radical rethinking by Suhrawardi and Shahrazuri into (...) a sophisticated system, L. W. C. van Lit unravels the history of this idea. Using a distant reading approach for measuring the transmission, he further shows how the idea remained relevant for Muslim thinkers through the centuries, up until today. (shrink)

In eleven first-rate essays, the normative thought of C. S. Peirce is not just exegetically exhumed from out of a sprawled corpus, a challenging task in its own right, but actually resuscitated to new life to address contemporary concerns. The goal of this collection is stated simply by de Waal and Skowronski in their introduction. Because there are “an increasing number of people . . . beginning to look at what Peirce has to offer more generally to contemporary esthetics and (...) moral philosophy . . . this volume will prove a valuable starting point for this [interest]” . While this volume is valuable and a successful contribution to Peirce studies, it is by no means a starting point for this kind of elaboration .. (shrink)

This book traces the development of formal logic from its origins in ancient Greece to the present day. The authors first discuss the work of logicians from Aristotle to Frege, showing how they were influenced by the philosophical or mathematical ideas of their time. They then examine developments in the present century.
