Lecture 22- Wayfinding Flashcards
What is wayfinding?
Moving through space, distinguish from navigation as this involves technology/satellites
What is deduction?
Based on Forms and Rules (Symbolic AI)
What is induction?
Pattern Finding (Neural Networks)
What is abduction? Can computers do it?
- “Guessing”
- Generating a hypothesis of what caused it or what the story is
- Computers can not do this (why we can’t talk to computers)
What can wayfinding be….
- From one known place to another (not just vast distances)
- Discover unknown places (at least by you)
- Can be solo or in a group (waka)
- Can be for hunting or scavenging+ collecting resources
Examples of wayfinding….
- Visiting friends
- Going to class across town
- Getting from your chair to the bed.
Is wayfinding embodied and situated?
Yes
Describe Inuktitut wayfinding…
- Winds (feel)
- Rocks with lichen patterns
- Snowdrifts against rocks
Describe Maori ocean wayfinding…
- Winds
- Ocean swells (look and feel) based on how close to islands
- Homing birds
- Reflections and shapes of clouds
How can names help with wayfinding?
- Some describe the actual thing
- Some are just names don’t tell you anything unless you have previously memorized their meaning
- Knowing names help success in wayfinding
What does a clear place help us remember?
The story
What parts of the brain do wayfinding?
- Hippocampus
- Entorhinal cortex
Both low and inferior in the brain
What are some cells/neurons invovled in wayfinding?
- Place Cells (Hippocampus)
- Grid Cells (Entorhinal)
- Boundary Cells (Subiculum)
- Head-direction cells
- Speed Cells
What are three things Boundary cells are invovled in?
- Scale (distance)
- Orientation
- Phase (how they overlap)
How are the different cell types tied together?
- Grid is based on head-direction and boundaries
- Place cells tied to grid
All together invovled in mapping out places
How do cells get meaning from connection?
- Optic flow
- Vestibular system
- Boundaries in the world
- Only develop through time
What is the order of child development for wayfinding?
- Head-direction
- Place cells
- Grid cells
How is spatial navigation tied to memory?
-Memory palace
-We remember events that have a place; we remember
places that have events
Why we don’t we remember the early years of our life?
Don’t have spatial system developed to record them
What happens when we lose the Entorhinal cortex and
hippocampus?
- Dementia and Alzheimer’s
- Lose connection to past
- Do complex wayfinding for simple tasks
- Can lose sense of self
What is conjectural knowledge?
Abduction, story based thinking
