  • If you give girls and boys language tasks, most girls will process the information in the same way (in a specialized language area)
  • help them with word storage and retrieval
  • But for boys, sensitivity to the modality of how words are presented means that an extra steps need to be taken to match words that are picked up by listening and words that are read on the printed page. No wonder dyslexia is much more common in boys - the separate system means that the sight and sound of words are learned as distinct processes.
  • ...4 more annotations...
  • As a result, verbal competence may be strong in one domain (oral speech for instance), but be weak in another (reading).
  • because boys require two areas and a matching of visual-auditory inputs, impairment in one system may cause the whole language coordination process to fail.
  • The visual-auditory gap may also be why some boys may need to read word-for-word outloud or to themselves (i.e. not silently read) in order to fully comprehend or remember the story.
  • Some careful consideration needs to made of instructional implications for boys given some of these new discoveries. Learning by listening and learning by reading are not synonymous; route-congruent factors(listening - oral presentation, reading - written response) may need to be considered when a learning gap or frank underachievement is seen, and an insistence on the availability of auditory-visual supports (reading along with books-on-tape, detailed handouts for lecture courses) should be a requirement of every classroom.

  • During the past 20 years or so, biological sciences have advanced to the point that scientists have begun researching biological mechanisms of brain function and suggesting some reasonably well-founded hypotheses for consciousness. Leading the way in these pioneering efforts, in my judgment, have been:   Gerald Edelman with his hypothesis of the Dynamic Core, Antonio Damasio with his concepts of  Protoself, Core Self, Autobiographical Self, Core Consciousness and Extended Consciousness, Joseph LeDoux and his emphasis on the intricacies of synapses and the emotional brain,
  • Rudolfo Llinás and his researches into ~40 Hz oscillations and synchronization, György Buzsáki with his discussion and exploration of neural mechanisms related to oscillation and synchronization in the neocortex and hippocampus for perception and memory, Joaquín Fuster, the world’s preeminent expert on the frontal lobes, and his concept of the "perception-action cycle," Susan Greenfield's notion of "neuronal gestalts" as a way of conceptualizing a highly variable aggregation of neurons that is temporarily recruited around a triggering epicenter. I use the neuronal gestalts idea in my way of visualizing the functionality of the dynamic core of the thalamocortical system, Eric Kandel who has explored short-term and long-term memory,
  • The late Francis Crick with his collaborator Christof Koch who have pursued the neural correlate of consciousness (NCC), Michael Gazzaniga with the concept of the left hemisphere ‘interpreter’ unifying consciousness experience, Edmund Rolls and Gustavo Deco with their mathematical models of brain function using information theory approaches for biologically plausible neurodynamical modeling of cognitive phenomena corroborated by brain imaging studies, David LaBerge with his discussion of the thalamocortical circuit and attention, Alan Baddeley who continues to refine his model for working memory, Philosopher John Searle who endorses the idea that consciousness is an emergent property of neural networks.

    "My objective in this website has been to bring together salient features of these assorted interpretations by science experts into a synthesis of my own understanding of consciousness. I consider these statements and interpretations to be a framework on which to build a fuller understanding as further data, concepts and insights develop from ongoing research."
