16
Q

What analogy has been given to the attempts to separate nature from nurture?

A

It is like asking whether width or length is more important when calculating the area of a triangle

17
Q

What inherited disorder is affected by both nature and nurture?

18
Q

What is PKU?

A

An inherited disorder that prevents the amino acid phenylalanine from being metabolised

19
Q

If PKU is detected at birth, how can the effects be minimised?

A

Placed on a diet devoid of phenylalanine

20
Q

How does PKU suggest that nature and nurture aren’t entirely separate?

A

As if the inherited disease can be treated via environmental manipulation, is the condition due to nature or nurture

21
Q

What is the alternative explanation to nature-nurture?

A

Diathesis stress model

22
Q

What is a diathesis?

A

A biological vulnerability

23
Q

Why don’t all people with predisposing genes develop the disorder?

A

As expression of the gene is dependent on environmental stressors

24
Q

Give an example of how nurture affects nature.

A

Neural plasticity

25
Whose research supports the concept of nurture affecting nature?
Maguire's
26
How does Maguire's research support the concept on nurture affecting nature?
The taxi drivers' posterior hippocampi (responsible for spatial memory) were bigger than the controls’
27
In the animal study that provides support for nurture affecting nature, what animals were studied?
Kittens
28
In the animal study that provides support for nurture affecting nature, what were placed on the kittens?
Large collars restricting what they could see
29
In the animal study that provides support for nurture affecting nature, where were the kittens raised?
In a drum with only horizontal or vertical stripes
30
In the animal study that provides support for nurture affecting nature, what was observed when the kittens were removed from their drums?
They were unable to see the lines of opposite orientation
31
What is epigenetics?
When different materials in our cells can switch genes ‘on’ and ‘off’
32
What controls epigenetics?
Life experiences such as diet and stress
33
How can epigenetics explain why cloning doesn't always work?
Epigenetic material is inherited from the donor egg cell
