Q

Why is there so much phenotypic and behavioral variation between dog breeds? How is
this different from other domesticated animals?

A

The phenotypic radiation of the dog has been the product of restricted gene flow and generations of intense artificial insemination.

Unique / different because they have been developed for highly specialized tasks such as herding, hunting, and retrieving.

Q

Be able to use some of the dog examples from the article (livestock herding, livestock
guarding, etc.) to explain the genetic foundation of behavior as it relates to what we covered
in class.

A

Herding breeds strongly express predatory motor patterns such as stalking. Both types of herding have been developed to work with livestock; however they present in radically divergent behavior responses

Q

What are the types of neurons? What signals do they send? What is the difference
between a monosynaptic signal and a polysynaptic signal?

A

Neuron- type of nervous system cell that processes/ translates messages through electrochemical signals

Monosynaptic- uses several neurons, more complex. Sensory neuron synapses with motor neuron. Motor neuron acts on effector.

Polysynaptic- most common, at least one interneuron between sensory and motor neurons. More interneurons, increase behavioral flexibility

25
What affects motivation? Apply to an example, like eating or drinking
Varies over time. Highest motivation inhibits others. Motivation to drink -- depends on when they last had drink, are they dehydrated, do they have visualization of water?
26
How do these behavior types interact? How can they be complementary?
Motivation changes reactions. Emotional state changes intensity. Hormones change behaviors. Complementary process - caustic substance gets on paw, neuron sends 2 signals
27
How is motivation affected by the animal's circadian rhythm?
Circadian rhythm - 24 hour cycle Affects motivation systems. Motivation systems affect rhythm of the animal.
28
Explain the classical ethological approach and the biophysiological theories of behavior.
classical ethological approach: motivation increases with length of time since last completed. Specific energy underlying motivation accumulates until behavior is performed biophysiological approach: behavior occurs due to observable physiological events in the body. Combination of internal and external stimuli control behavior.
29
What is the common principle when explaining animal cognition?
The simplest explanation is most likely
30
What is the function of learning?
Helps to predict and control future events
31
Explain habituation and sensitization.
habituation- decrease response to stimuli due to repeated presentation sensitization- animal encounters emotionally charged stimuli, more likely to react to new stimuli
32
Describe classical conditioning. What is the CS, US, CR, UR? Describe the two ways associations can be formed.
Classical conditioning- animal associates two events CS: initial event US: event associated with UR: reaction to US CR: reaction to CS CS - US - R Bell evokes idea of food which elicits salivation CS - R Bell takes on properties of food
33
What is instrumental conditioning?
Behavior of an animal is dependant on previous outcomes of said behavior - operant conditioning
34
What is positive/negative reinforcement/punishment? Provide an example of each
Positive reinforcement: adding a stimulus that increases the likelihood of the behavior occurring in the future - food, toy, verbal praise Negative reinforcement: removing an aversive stimulus increases the likelihood of the behavior occurring in the future - horse training, using pressure of legs to make them move Negative punishment: remove a positive reinforcer - ommission training Positive punishment: - Add an aversive stimulus
35
What is extinction? Explain how the partial reinforcement extinction effect works.
extinction: stimulus or behavior no longer followed by reinforcer Reinforcement in a random matter harder to extinguish - Partial reinforcement extinction effect --> if we reinforce in random matter, it will be harder to get rid of because animal doesn't know when reinforcer is going to come
36
How do factors like timing, strength of the reinforcer, strength of the stimulus, and species specific predispositions affect learning?
1. ) timing - reinforcer must occur shortly after event 2. ) Strength of reinforcer - association more easily formed with stronger reinforcer 3. ) Strength of stimulus - stronger stimulus, stronger response 4. ) Predispositions - innate learning preferences of the animal `
37
What is mutualism? Provide an example.
Each individual achieves some benefit from interacting - foraging birds - pack hunting wolves - meerkats communicating
38
What is altruism. Provide an example.
Individual pays a cost to help another -worker bees--> queen bee is the only one that can reproduce
39
How does kin-selected altruism work?
Increases likelihood of genes passing on through relative Likelihood predicted based on closeness of relationship Cost less than the benefit divided by the coefficient of relatedness
40
Why do animals form groups?
- safety in numbers - help in detecting danger - increased chance of obtaining food - capturing prey
41
What are some negatives of being in a group?
- share food that they discover - less access to food - more competition for reproduction
42
When do animals compete? How do they avoid competition in their groups normally?
Some animals compete for resources while others do not depend on them. Depends on the scarcity of resource, type of animal, hormones involved. The benefit needs to be more than the cost. Avoid constant competition by: - Social hierarchy - "Boss" - some can delineate through group - other groups less clear
43
When would an animal use acoustic communication, physical traits, or scent communication?
acoustic signals: vary in duration, pitch, amplitude - dog barking - cat hissing scent signals: last longer after signaler has left area - dog urine marking - cat scent gland physical traits: - physiological: feather colors, antlers - body movements: tail placement
44
What is the vomeronasal organ? What does it detect?
It is located between the nose and mouth. Is used to detect chemical signals.
45
What are epimeletic behaviors?
care giving behaviors
46
How does parenting ensure the fitness of the animal?
will increase chance that offspring survive
47
Provide examples of parenting behaviors.
nursing, raising in pack, protection
48
What are the benefits of play? How do they prepare they young for adulthood?
improve social skills; especially courtship, appeasement, competitive behaviors Prepare for coping with unusual circumstances - slippery surfaces - require animals to have balance
49
What factors go into choosing a mate?
time, energy, resources
50
Describe monogamy, polygyny, polyandry, and promiscuity as mating systems.
monogamy- one male, one female polygyny- male has several mates polyandry- female has multiple male mates promiscuity- males and females have multiple partners
51
When is it beneficial for animals to be monogamous?
- resources available - geographic distribution of mates - incidence of STD's - amount of parental care given - male guarding behavior
52
What are some of the roles of a polygynous male?
- control resources, specially when important for female reproduction - resource defence - protect females from predation - keep group together and safe
53
When does polyandry occur? Why would an animal utilize this system?
- more likely to ensure reproduction - sperm competition post-copulation - prevents males from destroying offspring as they don't know if they are theirs - females receive offerings from males
54
How does melatonin affect reproductive cycles?
Secreted in response to decreasing day length. Decreases reproductive activity Seasonal breeders
55
What effects do vasopressin and oxytocin have in prairie voles vs. montane voles?
vasopressin: "monogamy hormone" - Prairie voles (monogamous) have higher concentrations than montane voles - Prairie voles spend almost all their time with their mates - High vasopressin results in sexually possessiveness - Prairie voles- mate guard - More territorial Oxytocin: maternal hormone, social memory -montane voles low levels-->dont't pair-bond--> leave young early
56
How does sterilization affect reproductive behaviors and problem behaviors we see in companion animals?
Decrease of sexually dimorphic behaviors females: removes estrus behaviors males: decreases roaming behaviors, mounting, scent marking, aggression
57
How do animals avoid aggression? Why is this an important trait for survival?
By being submissive, helps them survive because they won't get into fights
58
When do animals display aggression?
When they are chasing prey or threatened
59
What is predatory vs. effective aggression
predatory- prey drive, is hardwired in their neural circuits effective- all other types of aggression
60
Do animals use aggression as a first line of defense or do they use other methods first?
May be submissive, depends on the animal
61
What is the killing bite?
The actual moment of the kill--> is a hardwired behavioral sequence that never changes
62
What is bite inhibition and why is it important? How is it taught?
Dogs have an inborn guard against excessive killing/biting. A typical dog learns bite inhibition during puppy play
63
What are the types of effective aggression?
1. ) Assertive aggression- includes dominant and territorial aggression. Social dominance/ alpha ranking 2. ) Fear-driven aggression- fear can cause a terrified animal to attack, has fear for its life, and feels there is no other choice than to attack 3. ) Pain-based aggression 4. ) Intermale aggression- linked to testosterone levels 5. ) irritable or stress-induced aggression- highly stressful conditions are more prone to aggression 6. ) Mixed aggression- experiences more than one motivator for aggression 7. ) Pathological aggression- medical conditions like epilepsy or head injury can produce aggression
64
How do people intentionally or inadvertently increase aggression in their companion animals?
Not properly socializing, not establishing owner as the dominant one
65
What are things we can do to decrease the risk of aggression in our companion animals?
Best to avoid it in the first place. Establish owner as boss, good training, and obedience
