Pavlov

• PAVLOV – AIM​

  To see if associating a reflex with a neutral stimulus causes learning to take place and produce a conditioned response​
• Procedure

  • 35 dogs​ put into a sensory deprived room – no sight, sounds or smells and strapped into a harness​
  • Tubes were surgically inserted into salivary glands​

  BASELINE​

  • Pavlov put the meat in the dogs mouth and measured saliva​

  CONTROL​

  • Pavlov showed the dogs food and measured saliva​

  EXPERIMENTAL​

  • Paired food with metronome, buzzer and tuning fork​
  • 20 times​
  • Measured saliva​
  • Presented NS without meat​
• Findings

  BASELINE​

  • Salivated 1-2 seconds​

  CONTROL​

  • Salivated after 5s, 6 drops after 15s​

  EXPERIMENTAL​

  • Salivated after 9s, 11 drops after 45s​
• Conclusion

  Dogs can learn by association as signalisation in the brain links the metronome to food and gives the reflex response of salivation when the metronome is present but food is not.​

  You can pair a neutral stimulus with an unconditioned stimulus in order to generate a new CR behaviour
• :) Cause and Effect

  highly controlled sensory deprived room, no extraneous e.g sight and smell of the food. T/f sure that manipulation of IV caused change in DV​
• :) Objective

  quantitative data (saliva produced). T/f internal validity, can only be interpreted one way
• :( Anthropromorphic

  large differences between dogs+humans e.g. dogs have a diff genotype. T/f can’t be generalised to human behaviour​
• :( Care over caging

  dogs kept in sensory deprived room and only fed in harness. T/f doesn’t meet ethical requirements for caging so unethical​
