6. How was the participants' response to light measured?
They had sodium chloride solution injected into their brain to trace the pathways relating to the optic nerve
They were anaesthetised and had bright slits put in front of their eyes, while recording individual neurons
They were assessed on how well they could follow a slit of light with their paws
They were assessed on how well they could follow a slit of light with their eyes
7. What was the research method used?
Laboratory Experiment
Quasi Experiment
Case Study
Controlled Observation
8. Which of these isn't a side of the Bateson Cube?
Quality of research
Certainty of benefit
Risk of permanent damage
Level of suffering
9. Who conducted the study that found that cats raised with different stripes covering their eyes became monocular, with each eye having neurons with different orientations?
Hubel and Wiesel
Hirsch and Spinelli
Loftus and Palmer
Binet and Simon
10. Which of these wasn't a control?
The cylinders used had the same dimensions
All the participants were reared by the researchers
Participants had a cylinder round their neck so they couldn't see their bodies
The age at which the participants first entered the cylinder
11. Which of these was different between cats in the different independent variables?
Those raised in horizontal condition struggled to jump down from tables/chairs
The cat was only able to follow a metal rod with the orientation it was raised in
There was no significant difference
Cats would only reach for a table in raised in the horizontal condition
12. When did biological studies take place?
7.5 Months
6.5 Months
6 Months
5 Months
13. What type of data was collected
Both Quantitative and Qualitative
Qualitative
Quantitative
14. Where was the dependent variable measured?
In a room with tables and chairs
It depended on the independent variable pertaining to that participant
In the dark room
In the cylinder
15. Which of these wasn't a conclusion/part of one?
These results are unlikely due to degeneration
How an animal of this species is raised can effect their ability to navigate their surroundings
There is no evidence of cortical areas being silent
Neurons changed their preferred orientation dependent on the stimulation they receive
16. Which of these isn't an application of this research?
It is possible to build neural pathways by behaving in certain ways/being exposed to certain stimuli
Damage to the visual cortex can be treated if done early enough
Children with a weaker eye should avoid using to reduce strain allowing it to naturally repair itself
Animals raised in a non-stimulating environment are likely to behave differently to those raised normally
17. Which of these was a permanent defect caused by the experiment
Lack of automatically stretching their paws to reach a surface
Clumsy and jerky head movements
Navigation using predominantly touch
Lack of startle response when an object rapidly approached them
18. Who were the participants?
Kittens reared in total darkness for 2 weeks
Mice reared in total darkness for 1 week
Puppies reared in total darkness for 4 weeks
Ferrets reared in total darkness for 3 weeks
19. How was the brain structure of the cats analysed, and how many were?
2 - Using sodium chloride which was injected into the brain using a micro pipette
1 - Using an MRI scan
4 - Using a CAT scan
25 - Using potassium chloride which was injected into the brain using a nano pipette
20. What was the difference in neurons between the two groups and a normal animal of their species
Normal animals of that species have more neurons
Participants didn't have any neurons with an orientation within 20 degrees of the opposite direction to their condition.
