Measuring Positive Welfare Flashcards
True or false
Some of the definitions of welfare include positive aspects of welfare
Other definitions of welfare simply emphasise the absence of negative welfare
True
True or false
Examining the different approaches to defining welfare has led to, over the last 20 years or so, to increasing interest in positive states and what they might mean
This is due to the view that absence of poor welfare does not mean good welfare
True
Positive states have traditionally been ignored due to the traditional view that positive states are less important than negative states
Give 3 examples of this
Positive states are viewed as satisfying opportunities vs a fitness need
People seem more comfortable attributing negative emotions to animals than positive ones
Legislation is focused on minimising poor welfare and not considering promoting positive welfare
In the field of positive psychology what is wellbeing considered to be?
In the field of positive psychology wellbeing is considered to be the experience of pleasant emotions (and mood states), and low negative emotions (and mood states)
True or false
In humans lower wellbeing scores are associated with lower mortality and morbidity
False
In humans greater wellbeing scores are associated with lower mortality and morbidity
There’s common brain structures and brain chemistry involved in reward processing that’s shared across mammals
What are these shared structure and chemistry?
The common brain structures are sub-neo-cortical limbic circuities
The common brain chemistry is dopamine and opiates
True or false
Similar reward systems to mammals have been identified in examination of avian brain structure and chemistry
True
True or false
Because there are similar reward systems to mammals and mammals have a conserved reward system the principal of homology can be used to aid identification of positive affective state indicators
True
What are the 4 concepts of how positive and negative aspects of welfare interrelate?
1) Some argue that positive and negative welfare are at opposite ends of a valence scale
This would suggest that the absence of negative welfare might lead you further along to positive welfare
2) Another idea is that there is a neutral point where there is no negative welfare but no positive welfare
In the neutral state you need more positive experiences to get you past a neutral state
3) Another interpretation of positive and negative welfare is that they might be qualitatively different aspects of welfare
4) Another concept of how they might interrelate is that they could actually be different aspects of welfare that may be supported by different brain circuits
In this situation overall welfare is a balance of its negative and positive components but there’s no compensation between them
True or false
Each discrete emotion can be described with the valence and arousal dimensions
True
What does Mendl et al 2010 and others suggest about the evolution of emotions?
Mendl et al 2010 and others have suggested that emotions evolved over time to guide the organism into activities that are going to maximise fitness by either:
Avoiding threatening/punishing activities and situations
Maximising acquisition of fitness enhancing rewards
How does Mendl et al 2010 conceptualise negative affective states?
Mendl et al would conceptualise the negative affective state as being in association of being either a:
Threat to fitness
This is associated with low valence and high arousal
Absence or loss of a fitness enhancing situation associated with reward
This is associated with low valence and low arousal
How does Mendl et al 2010 conceptualise positive affective states?
Mendl et al 2010 would conceptualise positive affective states as being associated with either:
Appetitive motivational states underpinning seeking and obtaining rewards
This is associated with high valence and high arousal
Absence of threat or post-consummatory states
This is associated with high valence and low arousal
What is a post-consummatory state?
Post-consummatory states are where the reward has been obtained and there’s satisfaction afterwards
Positive affective states have been less studied than negative affective states
However what do we know about positive affective states?
What we do know is that positive affective states tend to be:
Less intense
More labile
More subtle
True or false
To date research in positive affective states has focused on long-term states
False
To date research in positive affective states has focused on short-term states
What do you need in a study to test for positive affective states?
You need negative and neutral contexts and events to discriminate between them
This is so we know the indicator can consistently discriminate between positive and negative situations or states
What are the 3 reasons that there are few validated indicators of positive affective states?
1) We need our measure of positive affect to discriminate from negative affect
2) Requires testing/controlling for arousal be valence
3) Requires generalisation across different positive contexts
What are the 3 validity criteria for an valid indicator?
1) They can show homology with humans
2) They can discriminate between negative and positive situations
3) they correlate with other validated indicators
Give examples of potential indicators of positive affective states
Approach Play Anticipatory behaviour Affiliative behaviour Cognitive bias Vocalisation Facial expression Ear posture Body posture Qualitative Behavioural Assessments Heart rate variability Oxytocin Peripheral temperature Endorphins
Explain how approach can be used as an indicator of positive affective states
The assumption is that, like humans, animals generally approach things that they like
This correlates with Mendl et al 2010’s appetitive motivational states underpinning seeking/obtaining reward behaviour
As a result animals will seek things that benefit their fitness and that will be corresponding with reduced incidence of negative welfare indicators and/or increase in positive ones
However sometimes animals approach threatening stimuli
Give 2 examples of vocalisations that are indicators of positive affective states
High frequency 55kHz chirps rats make
Food calls in hens
What criteria does a play indicator of positive affective states have to meet to be valid?
1) The 3 criteria for a valid indicator
2) Play can be defined as not fully functional
3) Play is characterised as self-rewarding
4) Play differs in structure and/or timing from the adult, ‘serious’ form of the behaviour
5) Play is performed repeatedly but not in a stereotypic fashion
6) Play is initiated when the animal is in a ‘relaxed field’
What are the 3 main types of at and explain what they are?
1) Locomotor play
Locomotor play is associated with the individual playing alone and not interacting with anything else
2) Object play
Object play is where an animal is interacting with a specific object
3) Social play
Social play is where an individual plays with another conspecific
