ANSC 1210 Lecture 9: Lecture 9
Document Summary
Behaviour: allows animal to control their environment. Allows animal to develop and live in ways that allow species-species behaviour that they are motivated to perform. Animal limping around indicates it might be injured. Can not rely on intuitions and feelings to decide how the animals experience their lives. Use studies of motivation, preferences, aversions (experimental research) Behaviour: involves that static postures and active movement, noises, smell and the change of colour and shape that characterize animal life. Function: how did their ancestors behaved in the past. Causation: causes of normal behaviour, nerves, hormones. Examples of behavioural indicators of stress, pain, disease, affective state. Assessing behaviour, preferences, strength of motivation: behavioural observation (range of activities; time spent on activities; ethogram) Comparing animals (of same species) in different environments and activities they perform (eg. pig park) Enriched vs. bare environment different behaviour patterns: preference tests. Eg. variety of options for a particular type of food. Give info about animal"s choice or preference.
