Text-based and Signal-based Prediction of Break Indices and Pause Durations
The relation between symbolic and signal features of prosodic
boundaries is experimentally studied using prediction methods.
Text-based break index prediction turns out to be fairly good,
but signal-based prediction and pause duration prediction perform worse. A possible reason is that random signal feature
variations, as usually produced by humans, are hard to predict
When Spandrels Become Arches: Neural crosstalk and the evolution of consciousness
Once cognition is recognized as having a 'dual' information source, the information theory chain rule implies that isolating coresident information sources from crosstalk requires more metabolic free energy than permitting correlation. This provides conditions for an evolutionary exaptation leading to the rapid, shifting global neural broadcasts of consciousness. The argument is quite analogous to the well-studied exaptation of noise to trigger stochastic resonance amplification in neurons and neuronal subsystems. Astrobiological implications are obvious
