Q

Regulation of vital body functions occur at two levels:

A

Q

What experiences might make a pig less likely to start food searching?

A

Q

define displacement activity and an example

A

Animals in situation where two actions are likely, but a third is observed

Behavior that is seemingly irrelevant to the situation being faced by an animal

Coined by ethologists to label behavior that was seemingly out of context (or “displaced” from the situation)

Q

when may displacement activity occur?

A

when an animal is frustrated in its attempts to perform actions appropriate to the circumstances
Or
when it apparently experiences conflict among motivations for different actions

32
Q

how can you monitor physiological measurements?

A

Assays for blood sugars, hormones

33
Q

what are ways to monitor motivation

A
  • Observation of behavior
  • Brain recordings
  • physiological measurements
34
Q

how can observation of motivation be misleading?

A

Many causal factors (levels) may be high without there being any evidence of this from current activity

35
Q

what is a thermal neutral zone

A

Animal seeks to maintain itself in tolerable range

36
Q

explain negative feedback

A

As displacement from an initial state within the tolerable range occurs, this changed is monitored, and as soon as a set point is reached some corrective action is taken

37
Q

explain Feed forward control

A

◦ A displacement from the tolerable range is predicted and a correction is made before the state changes

◦ Animals use a variety of cues and previous experience to predict that the state will depart from tolerable range & they act in a way in which prevents this from happening

38
Q

Sollwert- “__________ behavior”

Q

Istwert- “________ behavior”

A

40
Q

41
Q

Rats & dogs show a clear preference for _______ & control over ____________

A

prediction

42
Q

predictable shocks caused _______ ulcers in rats then unpredictable shocks

A

fewer

43
Q

Unpredictability in feeding after regular feeding leads to increases in ___________ activity

A

adrenal cortex

44
Q

if adverse events are predictable animals can prepare for them behaviorally or by activating the ______________________________

A

analgesic brain opiate system

45
Q

what is frustration

A

A theoretical concept referring to a condition that is produced when an organism is blocked in its attempts to achieve a goal

46
Q

Levels of most causal factors which promote a behavior are high enough for occurrence of the behavior, but because of absence of a key stimulus or presence of some ______ or _______ barrier, the behavior cannot occur

A

physical

social

47
Q

feelings and emotions are causal factors that can have a substantial effect on decision making ______ System

A

Limbic

48
Q

feelings and emotions ______ casual effect on much behavior

A

modify

49
Q

feelings and emotions are active when individual has _______

A

feelings

50
Q

define feelings

A

stemming from the brain and involving sophisticated processing
◦ Brain construct involving at least perceptual awareness which is associated with a life-regulating system, is recognizable by the individual when it recurs and may change behavior or act as a reinforce of learning

51
Q

define emotions

A

A physiologically describable component of a feeling characterized by electrical and neurochemical activity in particular regions of the brain, autonomic system nervous system activity, hormone release and peripheral consequences including behavior

52
Q

Fear is a feeling, but ____________ occur

A

bodily changes

53
Q

the term feeling __________ the emotion

A

encompasses

54
Q

what happens during emotions

A

Physiological changes in the body associated with brain activity and often also behavioral modification

55
Q

a covered food bowl was associated with what in goats?

A

Time spent away from bowl, increased locomotion, little indication of autonomic changes and increased prefrontal cortical activity

56
Q

Near-infrared spectroscopy indicates _______ changes in the brain

A

hemodynamic

57
Q

food availability in goats resulted in:

A

Reduced locomotion, stayed near food bowl, showed sympathetically mediated arousal indicating anticipation

58
Q

care must be taken in the interpretation of ________

A

information

59
Q

Some physiologic and behavioral changes are associated with more than one _____

A

feeling

60
Q

when a dog has done something “wrong” that the owner has told it not to do is interpreted as indicating a feeling of ____, may be a response to the ______ behavior of the owner

A

guilty

current

61
Q

Torres-Pereira and Broom observed pet dogs that had been told not to take a food object, while the owner left the room some dogs ate the food object. what was the result of this study and what can we take away from it?

A

◦ While owner was absent, these dogs had higher HR than dogs that obeyed
◦ When owners returned after 30s and behaved exactly the same whatever the dog had done, carefully not looking at dog

◦ Difference in behavior between dog that had taken food vs. those that didn’t
◦ Suggests the concept of “wrongness”
◦ Cannot be separated from a prediction of negative consequences

62
Q

hypothalamus governs ___________ state

A

motivational

63
Q

hypothalamus is important in regulating several homeostatic mechanisms and related emotional reactions such as:

A

◦ Body temperature
◦ Ingestion of food & water
◦ Sexual behavior and rage

64
Q

hypothalamus regulates which system

A

autonomic nervous system

65
Q

hypothalamus links which two systems

A

nervous system to endocrine system

66
Q

how does the hypothalamus regulate the hypophysis (pituitary gland)?

A

◦ Neurohypophysis (ADH and oxytocin) (posterior pituitary gland)
◦ Adenohypophysis (prolactin, ACTH) (anterior pituitary gland)

67
Q

vassopressin

A

ADH, conserve water

68
Q

oxytocin

A

bonding, smooth muscle contraction, “love” hormone, released during parturition

69
Q

ACTH

A

adrenocorticotropic hormone, cortisol released, “stress” hormone

70
Q

prolactin

A

milk production or lactation, grooming behavior

71
Q

what are the main parts of the limbic system?

A

◦ Hypothalamus
◦ Hippocampus
◦ Amygdala

72
Q

what does the orbitofrontal cortex from the limbic system do?

A

important for decision making

73
Q

what is the nucleus accumbens in the limbic system?

A

produces feelings of pleasure and pain (addiction)

74
Q

what is the overall purpose of the limbic system?

A

Reacts to external and internal pleasant or unpleasant stimuli

vs.

Coordinates changes needed to maintain homeostasis (hypothalamus)

75
Q

the amygdala is primarily responsible for regulating our perceptions of and reactions to :

A

aggression and fear

  • fear, including the sympathetic nervous system, facial responses, the processing of smells, and the release of neurotransmitters related to stress and aggression

◦ Also helps animal learn from situations that create fear
◦ When animal experience events that are dangerous, the amygdala stimulates the brain to remember the details of the situation so animal learns to avoid it in the future

76
Q

what is the hippocampus important for?

A

storing information in long-term memory

navigation

◦ Living in a strange world where everything it experiences just fades away, even while older memories from the time before the damage are untouched
◦ Spatial and temporal pattern separation, sequential learning, short-term and intermediate-term memory

77
Q

what happens if the hippocampus is damaged?

A

animal cannot build new memories
