Pavlov

• Aim- investigate wether an UCS can be linked with a NS to produce CR
• Procedure - dog placed in a chamber- removes extraneous variables

  paired NS of metronome with food 20 times

  dog produced UCS of saliva

  metronome was presented without food

  cannula attacked to dogs mouth to measure saliva
• Findings - after 9 seconds salivation started

  45seconds = 11 drops of salivation
• Conclustion -NS paired with UCS forms CR such as saliva production
• Strengths of pavlov

  • high internal validity - sound proof chamber to remove external sounds distracting the dog. Collection of saliva in cannula , clear response to metronome = cause and effect relationship
  • clinical applications - eating behaviours - obesity understood Jenson et al overweight children string association between cues that predict food and salivation response - developed systematic desensitization
• Weakness of Pavlov

  • issue’s generalising animal studies as humans have large cerebral cortex and more complex cognitive processes
