A
  • prevents chronic stimuli from frightening an animal

  • classical conditioning

Q

What happened with Pavlov’s classical conditioning experiment?

A

dog had a tube it would salivate into – bell rang when person came in to feed it which caused salivation – thought it was a psychic or learned reflex but is CC

Q

What is a conditioned stimulus (CS)?

A

a previously neutral stimulus that after becoming associated with the unconditioned stimulus eventually triggers a conditional response

Q

acquisition vs extinction

A

acquisition: with repeated pairings of CS and US, CR becomes more reliable and grows in magnitude
extinction: If CS is presented without the US, then the CR becomes weaker in strength and occurs less reliably
***important that they’re paired every so often (charge the clicker)
CS + US = CR

What is discrimination learning (aka differentiation)?

Q

What are some examples of US’?

A

Q

What is pseudoconditioning?

A

it looks like associative learning but theres no association performed (a misinterpretation)
- occurs when a CS produces a response that looks like a CR but without pairing with a US
- need to know its actually associated with the US presented
ex. air puff (US) to produce an eye blink (UR)

Q

What do reinforcers or punishers do?

A

they increase or decrease the frequency of a behaviour
(primary = food // secondary = clicker)
- positive or negative
- punishment is more temporary (easier to figure out what to do if someone tells you everything you’re doing right instead of what you’re doing wrong)
- punishment can get saved up and reappears when ends (ex. dog gets on couch when you leave for work)

A

processes sensory signals and interrupts these signals, alerts brain of danger and can trigger anxiety – stores emotional memories

86
Q

What does the hippocampus do?

A

encodes threats into memories — learning and memories

A

inhibits serotonin and norepinephrine uptake - also an antagonist for NMDA receptors (negative for long term memory)

95
Q

What is gorging behaviour?

A

when they eat rapidly, can consume up to 10% of their body weight at one time (like wolves)
- can be socially facilitated due to a competitive environment

96
Q

What is the garcia effect?

A

when an acquired food aversion was due to a dog becoming sick from it in the past

97
Q

Why do dogs like to eat cat poop?

A

cause it has protein in it

98
Q

What is maternal indifference?

A

when the mother ignores her young, can be caused from endocrine changes or a hormonal defect

99
Q

Why might canabalism occur in dogs?

A

learned evasion of discomfort from either the bit, crown piece and brow band
fix by:

A

due to innate ticklishness and learned evasion – fixed by habituation and counter conditioning

154
Q

A

learned evasion – clicker training for approaching personnel, extinguish associations with being removed from group

156
Q
