Marginal value theorem
Optimality Model
Optimal behavior in a System, where resources are located in discrete patches (resource-free areas in between).
Resources deplete over time.
Leave patch if marginal capture rate in patch drops to average capture rate of habitat.
Individuals will stay longer if (1.) patches are farther apart and (2.) current patch is resource-rich
When should an organism use efficiency as measure instead of rate?
When efficiency increases the life span (Honeybees).
Risk-prone vs Risk-averse
Relationship between animals state and expected rewards.
Enough time to choose twice -> risk averse
What information does a caching Bird have In his memory?
When -> ability to project into future
Increased spatial temporal memory (hippocampus)
Advantages of optimality modelling
1. make testable, quantitative predictions based on a hypotheses about the currency (what is optimized) and constraints (energy costs, handling time, etc)
2. make explicit assumptions underlying currencies and constraints
3. Emphasize generality of simple decisions faced by animals
