Lecture 23 Flashcards
What is personality in terms of human psychology?
2 pts
Temperament relates to differences in emotionality, or inherited tendencies demonstrated in early life
* the foundation of personality
Personality relates to the ‘sense of self’ or personal character which develops over time
What is personality in terms of animal behaviour research?
2 pts
- Temperament has been used, largely because personality may suggest anthropomorphism
- The relationship between personality and a ‘sense of self’ is debated in animals
What is personality?
3 pts
- Personality, temperament, coping styles, behavioural types: now agreed to be synonymous
- Definition: “individual behavioural differences that are consistent over time and across situations.”
- Influenced by genes & environment
What is state, trait, and type?
3 pts
Increasing levels of complexity:
* State
- Response to a given situation
- Eg. Afraid, excited, or curious - in the moment
* Trait
- State observed in variety of situations
- Eg. Fearful, excitable, inquisitive - in general
* Type
- Combination of traits that makes up an individual’s character
What are the types of combination of traits?
2 pts
- Extraversion, Neuroticism
- Extrovert/Introvert
- Calm/Fearful
Why consider temperament?
2 pts
Temperament is an important selection criterion:
In companion species:
* Horse temperament affects use and quality as a riding horse
* Dog temperament used in service dog selection
In livestock species:
* Focus on traits related to production and management
What are some important temperament traits in pigs?
2 pts
- Sow line - low aggression, strong maternal traits
- Boar line - low aggression, ease of handling, low stress
Can we modify behaviour?
2 pts
Genetic selection
* Behavioural traits are moderately heritable
Management - learned behaviours
* Use daily management to ‘train’ animals
* Eg. habituation, positive reinforcement to reduce fear, early socialization to reduce aggression
Combined approach of genetic selection and positive management is most productive
What do we need to know before selecting for behaviour traits?
3 pts
Heritability of each trait
* can we expect genetic progress
Genetic variation
* how different are individual sows
Association between traits
* If we select against aggression, will we influence maternal behaviour
Can select individuals for sociability or suitability for a specific environment
What is the importance of individual differences?
2 pts
We manage the ‘average’ animal
* nutrition, temperature preference
In reality, we must accomodate the extremes
* the largest and smallest animals
* handling facilities, pen design
* fence height, distractions
In some cases the extremes refer to behavioural characteristics
* Flightiness, fearfulness
* Especially with farmed wild species - bison, deer, elk
What is the Myers-Briggs Type Indicator/DISC program
2pts
Model of temperament (personality)
* common tool in human resources (HR)
* management training: self-awareness, leadership
What does DISC stand for?
4 pts
Dominance, Influence, Steadiness, Conscientiousness
What is the Five Factor Model - ‘The Big Five’?
4 pts
- 5 dimensions in human psychology (OCEAN)
- Similar traits found in animal research - esp. E&N
- Openness, Conscientiousness, Extraversion, Agreeableness, Neurotocism
- 4/5 commonly found in animal studies - conscientiousness found in chimpanzees
What is the bold/shy continuum?
1 pt
It refers to an individual’s reaction to risky situations with the boldest individuals taking the most risks and the shyest ones avoiding them
What is behavioural ecology?
1 pt
explanation of temperament based on natural selection
