Self-organisation (Hemelrijk)
11 important questions on Self-organisation (Hemelrijk)
What is true about the explanation of complexity at group level?
What is true about starling flocks?
- Starlings show local coordination with only 7 of their closest neighbours for coordination of motion
- Simple interaction (attraction, alignment and avoidance)
- Simplified flying behaviour
- Staying close to the sleeping site
What does self-organisation implie?
- A pattern at a global level emerges from the interactions among the lower level units
- lower level units behave according to local information and simple rules only
- The emergent, complex pattern is more than the sum of the components
- Emergent properties arise unexpectedly
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
What complex phenomenon is shown in ant foraging?
- The exploitation of food sources nearest to the nest: attribute the complexity to:
- cognition of the individual: compare distances and quality
- interaction with the environment: pheromonal marking and following
How do ants choose the shorter path to a food source?
What is the spatial patterning of ants?
What are the advantages of asymmetric exploitation in ants?
How does spatial patterning in ants follow if there is a difference in food source quality?
What does the average dominance index describe?
Describe despotic vs egalitarian dominance styles
- Despotic: steep hierarchy, dominants have easier access to resources than subordinates (Java Macaque)
- Egalitarian: weak hierarchy, group members have equal access to resources (Celebes Macaque)
Describe the spacial structure of dominance
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
