Pavlov 1927

Sample

35 dogs of different breeds

Raised in kennels in lab

Tested whether UCS/R of food salivation could be conditioned to NS of metronome

Strength of sample

High generalisability, large sample + different dogs

Weakness of sample

Dogs biologically different to humans

They have bigger area in brain for processing smells

Around 40x larger than ours

Not representative, not generalisable

Procedure

1. Measured baseline salivation to meat powder

2. Conditioned dogs to associate NS with food then re-measured salivation

3. Metronome presented at tune of meat powder

4. Eventually metronome produced CR of salivation

Lab experiment

Soundproof room

Dog strapped to harness to stop it moving

Mouth linked to tube to drain a way saliva for measure

Removed dog's oesophagus

Strength of procedure

Standardised, high reliability

All dogs raised in lab and had same procedures e.g....

Weakness of procedure

Changed how many times he paired metronome sound with food depending on dog's attentiveness

Varied from 9-20 pairings

Not standardised, lacks reliability

Aims, results, conclusions

Aim: See if reflexive behaviour can be produced through learning

Results: Found that conditioned dog started to salivate 9 seconds after hearing CS sound, and by 45s had produced 11 drops of saliva

Strength of aims, results, conclusions

Application Capafons 1988 SD - used principles of CC, 90%✅

Weakness aims, results, conclusions

Social control
