Q

What is personality?

A

Personality are a set of behaviours consistently performed across multiple contexts

Consistent responses in just 1 context do not indicate personality because the individual might just have learned how to respond to that 1 specific context

Q

Why is there different terms for personality?

A

The differences in terms is because it took a while for it to be accepted that non-human animals had personalities and so the word personality was exclusively reserved for humans until recently
These days terms used to explain personality tend to vary dependent on the field of study, and in some scientific fields it’s still a controversial topic to say animals have distinct personalities

Q

Differences in personality are usually due to a mixture of what?

A

Genetic influences
Environmental influences
Some aspects of personality can be learned as long as they remain consistent across time and contexts after learning it it can be classified as part of the individuals personality

Q

Give 2 examples of physiological mechanisms that can be used to explain an individual’s personality

A

Individuals that show exaggerated stress responses across time and contexts might do so because they have above average adrenal activity levels
Due to varying adrenal activity individuals will have different stress response thresholds

Individuals that are trusting and affectionate may have above average oxytocin levels than other individuals of their species

Q

Some personality traits are so complex that we have yet to find a physiological explanation for them
Why is this and give an example of this?

A

This is mainly due to a lack of knowledge about the body and/or personality traits

An example of this is that people with psychopathic traits have certain brain characteristics however not everyone with those same brain patterns are serial killers

Q

You can make a normal distribution graph for a species population variation in a personality trait by measuring some physiological characteristics of the personality trait
Give examples of this

A

To measure stress variations you’d measure:

      - frequency of escape responses
      - cortisol levels
      - stereotypic behaviour rate
      - alarm call rate

To measure aggressiveness variations you’d measure:

      - latency to attack
      - testosterone levels
      - serotonin levels
      - frequency of threat postures

Q

Animal welfare is geared towards ensuring a good life for each individual animal
Animals welfare recommendations may not always work as a “1 size fits all” solution if there are individual differences to how animals respond to different scenarios
Give examples of this

A

Stressy individuals may fear environmental environment that a more relaxed animal would love

Animals can be quite selective about who they get on with, and so understanding how different personalities clash can improve group dynamics

Q

Give examples of how personality may have implications for conservation actions

A

Mate compatibility may be affected by personalities of the individuals which can alter breeding success in breeding programs

Individual personalities can also influence reintroduction success

Invasive species populations and individuals that are more likely to spread disease and understanding individual personality can help us identify which individuals are more likely to do this

Training and learning tasks can be tailored to specific personality types to improve their success

A

True

21
Q

True or false

Personality can’t help predict, and prevent, future problems

A

False

Personality can help predict, and prevent, future problems

22
Q

What is Belyaevs russian fox experiment?

A

Belyaev’s russian fox experiment is an experiment that wanted to see if choosing foxes based on their personality could recreate how dogs were created

23
Q

What does Belyaev’s fox experiment show?

A

Belyaev’s fox experiment shows that gene expression for a behaviour is interlinked for other phenotypic traits
So if you select for 1 specific trait you’d also select for a bunch of other unintended traits

24
Q

In humans how is personality determined?

A

In humans questionnaires are nearly always used to study individual personalities in humans
This is mainly because we can understand each other easily and self-report our own personality traits

25
Q

How are questionnaires used to detect non-human animal personalities?

A

For non-human animals we can’t directly ask them questions about their personality
To overcome this we can ask the humans who live and work closely with the animals about the animals personality
The longer a particular owner or carer has been with that particular individual animal the more robust/better quality of the data collected by the questionnaire
The experience of the survey respondents plays a role in the validity of the questionnaires as a tool to assess animal personality

26
Q

True or false

You can measure the responses to different but related situations through behavioural tests

A

True

27
Q

How would you measure the responses to different but related situations through behavioural tests?

A

Responses to different but related situations can be measured over time
This is done more in non-human animals than with humans
To do this you’d measure the individuals response to a standardised test/series of tests and repeat them at at different ages or across different contexts

28
Q

Give examples of tests we can use to measure responses to different but related situations

A 
Restraint test
Open field test 
Novel object test
Feeding competition test
Resident intruder test
Human approach test
29
Q

What happens in a restraint test?

A

A restraint test is where you’d limit the movement of an animal for a brief period of time and then record their responses
The animal can be restrained by tethering or close confinement in a weighing crate
Examples of responses you could record are vocalisation frequency, freezing behaviour, and escape behaviour

30
Q

What happens in a open field test?

A

An open field test is where you’d separate the animal from its pen or herd mates and place it in a novel arena for a brief time a land records its responses
Examples of responses you can record are vocalisation, exploration, freezing, and activity
The animal species social system can make the open field test more or less appropriate for the individual

31
Q

What happens in the novel object test?

A

The novel object test is a classic test
The novel object test is where you present the individual with a novel species relevant object in their home pen or in an experimental area and measure their responses to it
Examples of what responses you can measure are:
- latency to approach the object
- duration of contact with the object
- average distance from the object
- how they interact with the object

32
Q

What happens in the feeding competition test?

A

The feeding competition test is where you’d measure aggression and social rank by placing a single highly valued food source in a pen with a certain number of animals and record their responses
Examples of what responses you’d measure are:
- aggression
- duration/rate of food access
- latency to approach food resources
- displacement of food resources

33
Q

What happens in the resident intruder test?

A

The resident intruder test is where you’d get an individual animal and make them confront an unknown conspecific in their home pen and measure the responses
Examples of responses you’d record are aggression, tactile contact, and inter-animal distance

34
Q

What happens in the human approach test?

A

The human approach test is where an individual animal is placed in an arena with only a human in the pen with them and you’d record the animals response to the human
The location in which the experiment is done can be familiar or unfamiliar to the animal
Examples of responses you’d record are:
- latency for the animal to voluntarily approach the human
- responses to an approach by a human
- frequency of tactile contact between the animal and human
- duration of tactile contact between the animal and human

35
Q

With any personality test what is important for you to understand?

A

With all the potential personality tests it’s important to understand the individuals species behaviour and what they mean
This is because the same behaviour can have opposite meaning between species
Due to this you must know the meaning of the behaviour of your test species before interpreting any data from personality tests

36
Q

True or false

Personality tests on European mink showed that personalities are predictive of reintroduction success

A

True

37
Q

How can personality types be discovered?

A

Personality types can be discovered through correlating individual responses to either:

      - responses to different but related tests
      - responses to different questions in a questionnaire
38
Q

In human personality traits what are the “big 5” domains?

A

1) Openness to experience
2) Conscientiousness
3) Extraversion
4) Agreeableness
5) Neuroticism

39
Q

How would you map an individual’s personality type if they’re from a species distantly related to humans?

A

To map an individuals personality type from a species not clearly related to humans we can look at their coping style

40
Q

What are the 2 coping styles for species distantly related to humans and explain what they mean?

A

Proactive coping style
These are individuals that respond with the following behaviours bold, fight or flight, learn fast and impulsive

Reactive coping style
Theses are individuals that respond with shy, freeze or hide, take longer to learn and are more careful

41
Q

True or false

Some scientists theorise that more reactive individuals will develop stereotypic behaviour as a coping mechanism

A

False

Some scientists theorise that more proactive individuals will develop stereotypic behaviour as a coping mechanism

42
Q

How are coping styles distributed on a graph?

A

In some species the coping style responses are normally distributed with proactive and reactive individuals at the extremes

In other species the distribution of coping styles seems to be bimodal with 2 types of individual coping styles that do better under different conditions
Bimodal = 2 set behaviours that the population is split between and do better in different conditions

43
Q

How does evolution affect personality?

A

The evolution of personality means that if 1 personality isn’t useful then it won’t be seen in the next generation
However, the personalities remain in the species population in fluctuating numbers to ensure that at any given time some individuals of that species have the correct personality to survive
This ensures the survival of the species as a whole

44
Q

What maintains the variation in individual personalities within a population?

A

Fluctuating changes in ecological and environmental conditions maintains the variation in individual personalities within a population

45
Q

How can understanding personality affect decisions about which individuals we release into the wild?

A

Understanding personality and its effect on fitness and how this depends on environmental conditions may aid decisions about which individuals to release into the wild and when

46
Q

What 3 things do mortality rates depends on?

A

Ecological niche of the species
Species social structure
Environmental threats

47
Q

True or false
Understanding individual factors that increase an individual’s fitness may be a necessary tool for conservation, breeding and reintroduction programs

A

True

48
Q

True or false

Certain types of personalities tend to have certain diseases

A

True

49
Q
