WEEK 5 LECTURE VIDEO
Examples of reasons to find the way
- Foraging
o Depends on
▪ Memory for spatial location of food
▪ Memory for previous visits to the location
▪ Knowledge of the depletion rate of the resources
- Mate searching
o Depends on
▪ Defending a defined territory and advertising within it
▪ Actively searching within or beyond a territory
- Food storing
o Depends on
▪ Memory for spatial location of the food, even when environment changes
with the seasons
▪ In some cases, memory of the type of food stored in a location
Foraging, mate searching and food storing are behaviours that may rely on
- Orientation: taking up a particular bearing (not toward a particular goal)
o Kinesis
o Taxis
- Navigation: identifying a specific location, regardless of current position (toward a goal)
o Small scale
▪ Landmarks
▪ Path integration
▪ Cognitive maps
▪ Environmental geometry
o Large scale
A tendency to rely on one navigational cue over another often reflects
- Ecological constraints
- Exposure to certain cues during development
- Training in a specific laboratory paradigm
Animals switch between landmarks and environmental geometry as they move through a
environment but only one of the processes is directing behaviour at a given time
Document Summary
Foraging: depends on, memory for spatial location of food, memory for previous visits to the location, knowledge of the depletion rate of the resources. Mate searching: depends on, defending a defined territory and advertising within it, actively searching within or beyond a territory. Food storing: depends on, memory for spatial location of the food, even when environment changes with the seasons. In some cases, memory of the type of food stored in a location. Foraging, mate searching and food storing are behaviours that may rely on. Orientation: taking up a particular bearing (not toward a particular goal: kinesis, taxis. Navigation: identifying a specific location, regardless of current position (toward a goal: small scale, landmarks, path integration, cognitive maps, environmental geometry, large scale. A tendency to rely on one navigational cue over another often reflects.
