Transcript

  • 1. Perception, Cognition and Worldviews ...Or, everything you ever needed to know about Reality, your Brain and Learning but were afraid to ask.
  • 2. Your Brain Frontal Lobe : Abstract Reasoning Conceptual Memory Long-range planning Personality Social Behavior Parietal Lobe: Sensory Perception Spatial perception Amygdala Emotional reactions Fight-Flight Response
  • 3. Learning Physically Changes The Brain … And sever old ones Neurons make new connections
  • 4. ... when students interact with the world and synthesize information obtained by their senses, neurons receive input from each other and are altered , creating new electrical patterns between networks of neurons . During learning, changes may occur in the way neurons communicate with each other; in the efficiency of connections between neurons; in the number of neurons involved in the network; in the amount of energy required for communication to be initiated; and in how often communication occurs. New neural connections are formed constantly, while others are either strengthened or eliminated. A large body of research confirms that humans exposed to more enriched environments have larger , heavier brains with increased branching and connecting of neurons.
  • 5. Things that Stimulate New Neuronal Connections Enriched Environments : Novelty: Mu lti ple Mod alit ies : High Motivation & Focused Attention Significant Emotional Reaction But not too much emotion !!!
  • 6. Perception of Reality Perception is Variable : Position, Perspective, Attention, Filters and Framing all affect your perception . Perception is Unreliable : Scientists rely upon objective standards and mathematics to test a hypothesis . Perception is driven by the Mind as much as by the Senses : You see in part what you expect. You don’t hear much of what you dislike. FRAMING by others and your own WORLDVIEW create bias - a distortion of your perceptions .
  • 7. Perceptions can be manipulated
  • 8. Perceptions can be manipulated "Decisive" " Leftist " Fascist ! Commie ! "Patriotic" "Disaster" Evil “ Right-Wing” "Greatest" New and Improved Crook Un-American Unfair!
  • 9. WORLDVIEWS...
  • 10. What is a “Worldview” anyway?
    • A worldview supplies a particular community with the following:
          • Basic assumptions about what is real and what is unreal, true and false;
          • Values - moral and ethical standards
          • Historical and cultural examples including myths, legends, rituals, traditions
          • Rule sets to guide behavior and punish wrongdoers
  • 11. Worldviews are shaped by the culture around you
  • 12. Can Worldviews change ?
  • 13. YES ! Worldviews can change. 1. Cultural Evolution: 2. O.O.D.A. Feedback Loop 3. Paradigm Shift: Every society changes values and customs slowly over a long period of time. Individuals and organizations react to their environment when they O BSERVE , O RIENT , D ECIDE and A CT . This creates a steady flow of small changes in a worldview . Cataclysmic events or earth shaking discoveries can rapidly and dramatically change people’s worldviews -ex. Pearl Harbor
  • 14. 17th Century 18th Century 21st Century Human culture evolves in response to changes in the environment -be it social, economic, technological or physical changes. 1492 1776 2006
  • 15.  
  • 16. Paradigm : A dominant pattern of thought or model in a particular field (ex. Physics, Government, Art, Law etc.) Worldviews are generally larger concepts that contain multiple paradigms but some people use the two terms interchangeably Paradigm Shift
  • 17. VS. Aristotle Plato Ideas are Reality Objects are Illusions Two Worlds Order Fate Absolute values Opposing Worldviews Physical World is Reality Objects are Real One World Freedom Choice Relative values Spiritual-Utopian Scientific-Realist Moralist Logical
