4.1.2 pavlov

Question 1

what did pavlov develop?

Answer 1

cc after studying secretion in dogs

Question 2

aim

Answer 2

1. studied the reflex of salivating to see if a dog could be conditioned to salivate to a completely unrelated stimulus (metronome)
2. he aimed to see how the cerebral cortex works in making associations and to looks for a mechanism linking reflexes to the cerebral cortex

Question 3

procedure

Answer 3

• dogs restrained to harnesses in the cubicle and isolated from all distractions
• experimenter observed dog through one way mirror
• dog was presented food using a remote and a CS
• a tube carried saliva away from the dog to the container
• double steel doors which sealed
• vibrations, noises, temperature, odors, drafts eliminated
• only CS could influence dogs

Question 4

equation for cc in dogs

Answer 4

• before
Metronome (NS) —> no response
Food (UCS) —> salivation (UCR)

• during
metronome (NS) + food (UCS) —> salivation (UCR)

• after
metronome (CS) —> salivation (CR)

Question 5

results

Answer 5

• it took 20 or more pairings of the metronome and food to elicit salivation
• salivation started 9 secs after hearing metronome and after 45 secs 11 drops of saliva had been collected

Question 6

conclusions

Answer 6

• it is signalisation in the brain that links metronome to food and gives the reflex response to salivation
• conditioning is sensitive to many extraneous variables and to indivisible differences
