Blakemore and Cooper (1970) Flashcards
What is the aim of Blakemore and Cooper’s study?
to investigate the development of the primary visual cortex (in cats) and to find out if orientation selectivity are innate or learned (plasticity)
What is the IV?
horizontal or vertical environment
What is the DV?
visuomotor behaviour:
- startle response
- visual placing
- object detection
- neurophysical behaviour
What is the method?
Lab experiment
What are the strengths of a lab experiment?
- high control over EVs allow standardisation = more reliable
- replicable = more valid and reliable
- causality can be established
What are the weaknesses of a lab experiment?
- lack ecological validity
- lack mundane realism
- artificial
What was the design used?
Independent measures
What are the strengths of independent measures?
- reduced chance of demand characteristics and order effects
What are the weaknesses of independent measures?
- individual differences
- takes more time
- more participants needed
What is the sample?
not stated as to how many cats EXCEPT in part 2: x2 kittens used to study neurophysical effect
What are the weaknesses of the sample?
- small = lack population validity
- ungeneralisable to humans due to structural differences
What are the strengths of the sample?
lots of detailed qualitative data can be gathered
How long were the kittens studied for?
birth - 5 months old
How were the conditions chosen?
random allocation
How did the kittens live for the first two weeks of their life?
housed from birth in a completely dark room
