- 1How many participants were there?2 kittens
- 2How long per day did the kittens spend in the apparatus?5 hours
- 3How old were the kittens to start with and for how long did it last?From 2 weeks of age for 5 months
- 4What were the properties of the visual display apparatus?46cm diameter cylinder
Glass floor half way up
High contrast black and white stripes
(either horizontal or vertical) - 5Why was it okay that were there no control kittens?There was already an established standard for cat brain development
- 6What happened after 5 weeks in the apparatus?Several hours a day in a well-lit room with objects inside
- 7What were the 6 dependent variables? (what they wanted to observe)1. ability to move around
2. response to objects
3. jumping to the ground
4. judging distances
5. navigation
6. response to a rod held V or H - 8At what age were the kittens tested?7 months
- 9How did they test the kittens after putting them under anaesthesia?Presented either a V or H bright light to eyes - look to see reactions
- 10How else did they test the kittens?Natural startle response - rod moving towards the kitten
- 11What variables were controlled?Time in cylinder
Type of cylinder
The tests
Age
Conditions in general - 12In what way were the test kittens different from normal kittens in their navigating of the room?Touch > sight
Not as good at navigation - 13When would a kitten react to a rod?ONLY when it was the same orientation of the stripes in which they were raised
- 14Even though some of these problems disappeared after 10 hours, what remained impaired? (3)Tracking of objects
Bumping into objects
Judgement of distance - 1575% of neurones were ____________BINOCULAR
- 16What was strange about the polar histograms of the neurone activity?H cat = V neurones inactive within 20 degrees
V cat = H neurones inactive within 20 degrees - 17Why did they conclude that changes are not the consequence of degradation?No evidence of silent or missing cortical cells in the cortex
- 18Neurones change preferred orientation due to what?Stimulation of the visual cortex recieved
- 19Does this suggest that brain plasticity is NATURED or NURTURED?Nurtured
