Spatial learning is a more complex modification of behavior based on experience with the spatial structure of the environment.
Niko Tinbergen showed how digger wasps use landmarks to find nest entrances.
A cognitive map is an internal representation of spatial relationships between objects in an animal’s surroundings often using particular landmarks.

In associative learning, animals associate one feature of their environment with another. Example: a mouse will avoid eating caterpillars with specific colors after a bad experience with a distasteful monarch butterfly caterpillar.
Classical conditioning is a type of associative learning in which an arbitrary stimulus is associated with a reward or punishment. Example: a dog that repeatedly hears a bell before being fed will salivate in anticipation at the bell’s sound.
Slide 29
Operant conditioning is a type of associative learning in which an animal learns to associate one of its behaviors with a reward or punishment.
It is also called trial-and-error learning.
Example: a rat that is fed after pushing a lever will learn to push the lever in order to receive food.
Example: a predator may learn to avoid a specific type of prey associated with a painful experience.
Slide 30
Cognition is a process of knowing that may include awareness, reasoning, recollection, and judgment.
For example, honeybees can distinguish “same” from “different.”
Slide 31
Problem solving is the process of devising a strategy to overcome an obstacle.
Example: chimpanzees can stack boxes in order to reach suspended food.
Some animals learn to solve problems by observing other individuals.
Example: young chimpanzees learn to crack palm nuts with stones by copying older chimpanzees
