BIOL 354 Lecture Notes - Lecture 9: Spatial Memory
Document Summary
Search image theory-animals form a vivid representation of the target in their minds, which becomes more and more detailed with experience. Berry picking in humans, by the end of the trip, you"re really good at fi(cid:374)di(cid:374)g those (cid:271)erries. Overtime, forager becomes more successful, may lead to evolution of better prey camouflage. Optimal foraging theory-(cid:862)to eat or (cid:374)ot to eat(cid:863) Handling cost-time to eat food, risk in taking. Where to eat (think of the mangoes) How long to stay in one food patch before moving. Quality of patch decreases overtime, as animal eats. Stay until rate of food intake associated with next item in patch is equal to the average rate of food intake across all patches while factoring in the cost of switching. Greater travel time/cost, longer you should stay. Sometimes there can be a greater risk associated with foraging. Public information-use actions of others to gain information about changing environmental changes.
