63
Q

Study indicates that people with pets have reduced incidences of stress related disorders. This is what kind of study? Why?

A

Retrospective. This does not say if you will not have high blood pressure if you own a pet.

64
Q

You measure the blood pressure, heart rate, and stress levels of people. You let those people interact with their pets, you measure the vitals again. They have decreased.
What kind of study is this and what does it create?

A

Prospective study. It is also a repeated measure study. It creates a cause and effect

65
Q

What is the problem with repeated measure studies?

They are hard to do and hard to control

66
Q

82 people with heart disease. 6% own pets and die within a year. 28% without a pet died within a year. What kind of study is this and how would you turn it into the other one?

A

This is retrospective. To make it prospective, you would start with diagnosed people that did not own pets and then give them all pets and see what happens.

67
Q

Are service animals an example of homeopathy?

A

It depends! Emotional support dogs or animals that relive stress instead of using a medication could be considered homeopathic.

However, a seeing eye dog would not be homeopathic. There are no medications to cure blindness.

68
Q

How have animals affected research? (Broadly)

A

Most of the cures for human disease and many other techniques are possible due to animals.

69

70
Q

What is retinitis pigmentosa and how have pigs contributed to our understanding of it?

A

Middle aged people start to gradually lose their sight. We learned from pigs that lots of vitamin A can delay the process.

70
Q

What are two ways to evaluate economic importance?

A

Gross income generated, economic impact factor.

71
Q

What is gross income generated?

A

How much money you get when you sell something. Don’t factor in expenses.

72
Q

What is economic impact factor??

A

Estimates economic value of businesses that are needed to support production.

73
Q

Give an example of how the economic impact factor works.

A

This estimates and includes all things someone would need to raise cattle. For example, vet bills, feed manufacturers…

74
Q

Calculate the impact factor for a large dog that was purchased for $150 and has an ownership cost of $1464.

A

Impact factor $1464/$150

=9.8

This means that an additional $9.80 in goods and services should be generated for every $1 of sales price.

75
Q

What is an ownership cost?

A

The cost of maintaining an animal. May include vet bills, food, toys…

76
Q

How do you calculate impact factor?

A

Ownership cost / Purchase price.

A

$4.2

80
Q

What is the economic impact factor or pets?

A

$8.8

81
Q

Why might the gross income be higher for livestock animals?

A

There is more livestock than pets.

82
Q

Why might the economic impact factor for pets be higher?

A

People are more willing to spend money on beloved pets. They also tend to live longer.

83
Q

How do you calculate total economic contributions?

A

Take the gross revenue and multiply it by the economic impact factor. Then add the gross revenue to that.

(gross revenue) + (gross revenue x Economic impact factor) = total economic impact.

84
Q

What is the estimated total economic contribution of swine in NC?

A

$5.3 billion.

85
Q

What is the gross revenue that the swine industry generates in NC?

A

$1.1 billion

86
Q

The economic future for animal related businesses can be summed up in four traits:

A

Future trends in companion animals

Projected 7-10% yearly growth

Increase in “high-end” products and services including “home-delivered services.”

Growth of pet superstores, or one stop shopping.

87
Q

Where is the US in the production of animal commodities on a worldwide basis?

A

First and second in a lot of them. We feed our own country and then export a lot of the food. We also give away lots of food.

88
Q

Why is animal behavior important to us?

A

Animal Well-being. (Are they limping, acting strange?)

Biological changes (Is the animal in heat, pregnant?)

Management conditions

89
Q

You classify the animal behavior into two sections:

A

The biological need, and the behavioral mechanism

90
Q

In animal behavior, what does the classification of Biological need mean?

A

What the animal gains from the behavior.

91
Q

In animal behavior, what does the classification of Behavioral mechanism mean?

A

How the animal knows or learns to perform the certain behavior.

92
Q

What are the 6 behavioral mechanisms?

A

Instinct, Habituation, conditioning, trial and error, reasoning, imprinting

93
Q

What are the 5 biological needs?

A

Sexual behaviors, caregiving behaviors, care-soliciting behaviors, agonistic/social behaviors, feeding behaviors.

94
Q

Describe the behavioral mechanism- Instinct:

A

Behaviors inherently present at birth. Also sometimes referred to as reflexes. Usually controlled by biological changes within the animal

95
Q

Describe the behavioral mechanism- Habituation

A

Lack of response to a repeated stimulus. Learned behavior!

96
Q

Describe the behavioral mechanism- Conditioning. List the different types.

A

Association between a behavioral response and a given stimulus

Positive stimulus = reward
Negative stimulus = punishment

97
Q

Who normally initiates a response in the case of conditioning?

A

Another animal (human mostly)

98
Q

Describe the behavioral mechanism- Trial and Error

A

Trying various responses to a stimulus until a reward is received.

99
Q

What is the difference between trial and error and conditioning?

A

In trial and error, the animal seeks out the stimulus itself!

100
Q

Describe the behavioral mechanism- Reasoning

A

Ability to respond correctly to a stimulus the first time it is applied. This is not very common.

101
Q

Describe the behavioral mechanism- Imprinting

A

Mechanism by which young animals bond with their caretakes. Usually the mother. This is a very poorly understood concept.

102
Q

Which is the only mechinism that is innate?

A

Instinct.

103
Q

Animals playing is instinct

instinct and learned

105
Q

Give an example of instinct

A

Puppies suckling for milk

106
Q

Give an example of habituation.

A

107
Q

Give an example of conditioning.

A

A money hits a button and is given a treat. He starts to hit the button without prompting.

108
Q

Give an example of trial and error.

Originates from mother or father. Protection, nourishment, training young

113
Q

Describe the biological need- Care-soliciting behaviors

A

Used by young to signify they need assistance.

Occasionally used by injured or disabled mature animals.

Q

Describe the biological need- agonistic/social behaviors

A

Used to establish social hierarchies

Associated with fight or flight and how animals interact with each other.

114
Q

Describe the biological need- Feeding behaviors

A

Associated with obtaining food!
Mostly associated with animals that require predation or foraging in order to meet nutrient needs.

115
Q

Every pheromone is sexual

A

No! pheromones can be sexual, social, ect..

116
Q

When classifying behaviors, you must:

117
Q

Often, a single behavior will fulfil more than ________

A

One biological need

118
Q

What are three good hints for classifying behaviors?

A

List both the mechanism and need

Read the entire paragraph first

Don’t confuse instincts or reasoning.

119
Q

What are the three ways that we attempt to quantify animal intelligence?

A

Anatomical approach, vocalizations, Comparison of learning rates.

120
Q

What are some reasons that we use different measures when quantifying intelligence?

A

-No single approach is perfect

-Each has weaknesses and advantages

-It can be very difficult to estimate across different species.

121
Q

How do we use the anatomical approach to decide intelligence?

A

brain weight to body weight ratio.

122
Q

What is the biggest obstacle to brain weight to body weight ratio as an intelligence ranking system?

A

Artificially selection! Our livestock has been bred to be fatter and bigger. This lowers their ratio and makes them look dumber than they are.

123
Q

List the brain weight/body weight ratio percentages:

Human=
Cat=
Dog=
Rat=
Goat=
Pig=

A

Human= 2%
Cat= 1%
Dog= 0.5%
Rat= 0.3%
Goat= 0.3%
Pig= 0.05%

124
Q

How do we use the vocalization approach to decide intelligence?

A

The number and types of vocalizations.

More vocalization = smarter
Complex vocalization = smarter

125
Q

What is an advantage to using the vocalization point of view to measure intelligence?

A

They are innate. We cant munipulate them.

126
Q

What is a disadvantage to using the vocalization point of view to measure intelligence?

A

Bias! Humans want to believe that certain animals make certain vocalizations.
Ex: a pet dog or cat.

127
Q

What is human bias when studying animals called?

A

Anthropomorphism

128
Q

What is the number of simple vocalizations for these animals. Complex?

Sheep
Horses
Pigs
Cats

A

Sheep = 3, 0
Horses = 5, 0
Pigs = 4, >57
Cats = 8, >15

129
Q

How do we use the Learning rate approach to decide intelligence?

A

We can teach animals, generally through positive reinforcement and conditioning.
We compare learning rates of species exposed to the same task

130
Q

What is the most popular learning rate test for animals?

A

The maze test. How many errors each species makes before completing the maze.

131
Q

What are two advantages of the maze test to measure intelligence?

A

The test is exactly the same for every animal.

You are actually having the animal learn something. This is a good quality of brain power.

132
Q

What are three disadvantages of the maze test to measure intelligence?

A

The animal may not be motivated the same as other species.

Generally, the animal needs to be hungry. This may involve depriving the animal of food. This is a welfare issue.

Predators and prey are going to preform differently. Predators will probably do better because they are practiced in hunting skills.

133
Q

How is learning a dynamic process?

A

People learn, forget, memorize, or remember for short term. It is constantly changing.

134
Q

In the learning process, what are the three stages?

A

Acquisition, Extinction, Spontaneous recovery.

135
Q

Describe Acquistion

A

The first stage of learning. It is the initial learning.

136
Q

Describe extinction

A

Thes second stage of learning. This involves forgetting the learning after not using it for a while.

137
Q

Describe spontaneous recovery

A

The last stage of learning. You remember or relearn when you need to do it again.

138
Q

Why is it hard to decide if someone is smarter based on the three stages of learning?

A

It depend on which stage you are focused on! Someone might forget more but recover the knowledge faster.

139
Q

What is behavioral science also called?

A

Ethology

140
Q

What is ethology?

A

The study of animal behavior. It attempts to classify how animals respond to various situations. It works to link behaviors with animal well being.

141
Q

What is the goal of understanding animal behavior?

A

to improve the environment for them and understand them better to help.

142
Q

Improved knowledge of animal behavior will lead to ___________

A

Better management systems

143
Q

What is the biggest issue in animal behavior?
